Understanding the design and operation of the mechanism will facilitate the choice of septic tank sewage treatment plant and its installation.

Construction of various modifications have some common components. Sewage treatment system is a sealed tank, comprising one or more compartments.

The construction of a septic tank

To prevent contamination of ground volume of waste coming into the hole, it should be in the range of 1 cubic meter / day. However, in a house where there is a bathtub, toilet, sink and washing machine, this requirement is not feasible

septic chambers separated by partitions. fluid movement between them is carried out by an overflow pipe.

The first compartment of the domestic sewage is brought home the drain pipe, and from the last camera output purified water into the ground or semi-purified - on soil advanced treatment.

Scheme septic device

Many models have a mechanical filter - separation of the precipitate occurs without a chemical reaction, and addition of reagents. Effluent filtered through a sand, gravel or expanded clay (+)

The main components of water treatment units are as follows:

  1. Capacity to defend drains. Storage tanks are made of plastic, metal, concrete or brick. Most preferred model of fiberglass and polypropylene - materials resistant to abrasion, and ensures the tightness of the tank for the entire lifetime.
  2. The incoming and outgoing line. Overflow pipes are installed under the bias, providing unimpeded flow of fluid between the tanks.
  3. service elements. Inspection chambers and manholes. It sets at least one well on the outside of the track sewer. With increasing extent of more than 25 m threads arranged additional revision.
  4. Ventilation system. Regardless of what bacteria (aerobic or anaerobic) are involved in the processing of waste masses for normal activity of microorganisms, removing methane and maintain the desired temperature requires breathability.

The simplest scheme for venting comprises one local sewer in the beginning of the riser system, and the second - on the end section of a septic tank. The regeneration of filtration fields vent stack is installed on each of the drainage pipe.

Location septic tank

The ventilation system ensures the removal of the gases formed as a result of the decay of organic matter. Natural ventilation based on the difference of air pressure - supply opening is located lower than the exhaust 2-4 m (+)

The overall principle of the treatment plant

Operation of any septic tank is based on the principle of gravitational sedimentation and biological filtration by natural or forced. Perhaps the use of drugs and biofermentnyh biofilters. Conventionally, the sequence of purification of sewage can be divided into a number of standard steps.

Step 1.primary treatment. According to the sewer from the house waste water flows into the first tank or compartment. Here there is a rough cleaning of suspended particles larger. Heavy slurry (sand and similar insoluble inclusion sinks) are deposited on the bottom of the chamber. Light fraction (fats and oils) rise to the surface and flow into the next compartment.

Step 2.Decomposition heavy particles. Sank to the bottom of the first chamber waste start to ferment and decompose - process time of about 3 days. As a result, impurities fall into dough, carbon dioxide and water.

The purification process

At the bottom of the first compartment accumulates yl which periodically must be removed. Effectiveness of cleaning fluid in the first chamber is about 60%. For the removal of the soil that is not enough, therefore, requires post-treatment of (+)

Step In the second chamber is re decomposition impurities. In some septic tanks at this stage by the action of specific bacteria and decompose chemical agents (personal hygiene waste) and organic compound.

Step 4.liquid withdrawaland. The further way of water depends on the type of cleaning system. The purified liquid can flow into a tank for subsequent watering the garden.

If insufficient degree of purification, the water passing through the post-treatment process infiltrate drainage well, fields for filtering dirt etc.

Schematic description of the operating principle of a conventional septic tank process transmits common features. Each modification treatment plant has structural and operational performance nuances.

Features of different types of septic tank

All water treatment plants are divided into three categories: storage tanks, septic tanks-models with additional cleaning and dirt septic tanks deep biological treatment of wastewater. Consider how each of the septic tanks in more detail.

Cumulative sewage system

In fact, storage septic tank, an analogue cesspool - sealed a solid one-chamber tank, which receives sewage. In designs accumulative type waste is collected and stored temporarily. As the filling of the tank is pumped sewage using vacuum trucks.

storage tank

The volume of the container varies within 1-4 cubic meters tank dimensions are matched to the particular needs of the family - namely, the average daily volume of sewage

Scheme sewage system is very simple and consists of the drive and the outer pipe.

Septic may further be provided with:

  • check valve - prevents motion of sewage in the opposite direction;
  • signaling with the sensor level effluents - notify the owners of the filling of the tank and the need for pumping sewage.

Popular models of storage septic tanks: Bars-H, beetle, Rodlex,cleansing.

cumulative septic tank

Setting drive justified in case of impossibility arrangement subsequent filtration system or septic seasonal use, for example, cottage

Sediment from soil aftertreatment systems

Units with additional cleaning groundwater belongs to the category of the overflow structures. The system consists of two or three sections and devices for additional filtering wastewater. Once in the holding tank, waste masses are asserted and decompose under the action of the anaerobic bacteria.

Flowing from the vessel into the vessel, the mass of waste pass several stages natural separation. However, the degree of purely mechanical processing reaches the maximum 65 - 70%. Therefore, wastewater treatment for high-grade, emerging from the lagoons, must undergo additional advanced treatment before disposal and discharge of the relief on or in the ground.

Septic tank Soil additional cleaning

The initial filtration is carried out in a sealed tank. Semi-purified waste water derived in the dirt after-treatment - drainage basins without a bottom with a "filter bag" in the ground

Ways of organizing dirt tertiary sewage treatment:

  • seepage pit;
  • Field underground purification;
  • filter trench.

filter well. It fits in sandy soils of varying size and density of addition. Can be used in sandy loam with a minimum number of plasticity.

produce filter well It can be of precast concrete, stone or brick. Kosntruktsiya has no bottom - the base of the well is filled with gravel. The height of the drainage layer - 1 m.

drain well

to the arrangement of requirements: the distance from the "filter bag" to groundwater - a minimum of 100 cm. filtration area for sand - 1.5 m, sandy loam - 3 m per one family member

Field underground filtration. The complex of perforated tubes arranged on the filter area - sand and gravel backfill. The clarified supernatant in the septic tank, and water is supplied to the irrigation pipe with holes.

Liquid seeps into the groundwater and into the filter. Pipes can be connected to the vent manifold jumper tap settle or separate risers ventilation.

filtration field

Technical requirements: the height of gravel and sand cushion - 20 cm, depth of irrigation pipes - 0.5-1.8 m from the surface, at least one of m should be between conventional systems and the bottom level groundwater

filter trench system. The construction used in clay soils and divisions, with discharge of treated wastewater into an unused reservoir. In the prepared trench depth of 1.5-1.7 m are arranged in two tiers pipe: the upper called irrigation lower drains.

Supernatant in the septic tank the water enters the upper conduit, and seeps through the perforation passes through the final purification gravel and sand. Then passed through a natural precoat filter effluents collected underlying drainage pipe - drains through which discharged to the disposal site.

absorbent trench

Having filtration, water enters the lower tube and dumped on the terrain - part absorbed into the ground, and some - in the nearest pond or ravine

The main "element" post-treatment and disposal of sewage water taking acts not design, and directly laminate the precoat filter. It is necessary to collect only the interface for efficient fluid distribution within the Earth.

Septic tank with biological treatment

Bioseptik - deep cleaning station based on micro-organisms. The system is a sealed single block, reinforced ribs and subdivided into several chambers. The number of sections determines the efficiency of purification.

Fluids entering of the soil pipe inside the septic tank, subjected to various purification methods. Water output is cleared by 90 - 96% or more, so you can use it for watering plants or poured into the reservoir. Additional filtering in groundwater systems is not required.

Septic tank with biological treatment

Sewage treatment plant with biofiltration can be installed on any geological conditions of sites, regardless of the level of groundwater. Septic fully operational - a body with "stuffing" should only be installed and connected to the sewerage (+)

Operation "bioseptika":

  1. The first chamber serves as a sump. Here, impurity particles are divided into heavy and light fractions and film forming floating precipitate anaerobes and processed without needing supply of oxygen.
  2. In the second compartment organic and inorganic wastes are decomposed by aerobic microorganisms requiring oxygen for regular processing of the private and life.
  3. In the third chamber the filtered effluent or disinfected with chemical components are subjected to repeated impacts aerobic bacteria.

To activate the aerobic microorganisms in the septic tank chamber must act oxygen - the device is provided with an aerator. Therefore, the majority of stations Bioremediation are volatile.

The basic scheme of popular models

In an effort to improve the effectiveness of the septic system, manufacturers are constantly improving the product units. Some are trying to facilitate the design and make the scheme work more understandable, while others - increase the number of cycles and the cleaning quality, introducing innovative technologies.

Tank - a complex purification Infiltrator

septic tank Tank - waste water treatment system with after-treatment devices dirt. The one-piece device chassis is reinforced by thick ribs 17 mm thick. Due to its design septic tank may be installed in different soils.

Due to the block-modular structure, if necessary, to get a "ramp up" of the system.

septic Tank

septic tank consists of two or three chambers. Filters, partitions and biogranules allow sewage purifying three ways: mechanical, biological and chemical

water purification loop in a septic tank is divided into the following stages:

  1. At the receiver, the heavy precipitate inorganic substances. The clarified water overflows into the second compartment.
  2. The liquid is subjected to anaerobic treatment and the fermentation process is split into simpler compounds. In the second chamber the membrane disposed delaying fat fraction.
  3. The sumps into two compartments purification cycle ends at Infiltrator. In the three-chamber tanks, the water passes the biological purification. The last compartment is filled with a colony of bacteria capable of utilizing impurity.

At the output of purified water at 75-80% (depending on the number of cameras). For a complete clarification of the system is complemented by Infiltrator - a bottomless reservoir set in a trench in the "cushion" of sand and rubble.

Operating principle

Passing through the filter layer, impurities deposited unmetabolized - enters in the ground water, purified to 95-98%. Alternative to infiltrate - drain well or filtration pad

Tapas - a multi-stage biofiltration

septic tank Tapas - sewerage system biochistki deep. The device unit is fundamentally different from the structure of "horizontal" septic tanks. Vertically oriented body is divided into 4 sections, circulating between which impurities are purified by 98%.

Septic running from the power supply. All wastewater treatment process within the structure takes place on a given cycle, thanks to well-thought-out internal structure

Compartment 1. The primary impurity into a chamber and exposed to aerobic bacteria are split into lighter components, water and sludge.

bay 2. The camera fall effluent purified to 45-50%. In the aeration tank the air flow raises the fine particles to the water surface. The compartment has a pyramidal shape, that facilitates rapid precipitation of sludge. After airlift liquid flows into the next chamber.

Compartment 3. In the secondary clarifier effluent re-converted to water and silt.

Compartment 4. The cell accumulates purified water. As the filling tank rises liquid level sensor transmits a signal to the drain pump of the container is full.

Triton - volatile cleaning system

septic Tank Triton performs mechanical and biological filtration with additional cleaning dirt. Important advantages of Triton models: compact and simple design. For suburban area, small country estate or put a bath often selected septic Triton-Mini.

Two tanks are interconnected in the top and bottom nozzles. This solution increased the space for accumulation of sludge on the common bottom and the semi-purified water allowed to flow freely into the next compartment.

Fast - aerobic recycling technology

septic tank Fast - an innovative solution treatment of domestic sewage. The unit is designed so that the work of processing the waste mass is carried out as quickly as possible.

septic Fast

The treatment plant consists of a receiving unit, a secondary settling tank, aeration tank built, the pump and the module, where processing is performed aerobic effluent. Habitat microorganisms - specific cell (+)

Sewage entering the receiving chamber, immediately processed for aerobic microorganisms. With the compressor and fan air is supplied into the septic tank - cleaved and activated biomass waste. The cellular structure of impurity module, air and microorganisms active mixed - effluents are converted into water and precipitate.

Simultaneously, the job included airlift providing displacement liquid in the second compartment. Here the water is clarified and settles naturally - yl falls to the bottom. Work on the expansion of sewage continue to anaerobic bacteria.

The clarified liquid is discharged through the outlet. In parallel with the discharge is sending a new batch of sewage.

Septic Fast - a self-regulating system that adapts to the wastewater with larger particles or impurity with the chemical components. Due to the cellular structure of the module bacteria are able to heal itself.

From the action of aggressive chemicals kills microorganisms deposited on the walls of the septic tank and drains the surface. Bacteria inside the cells survive and continue to actively proliferate.
