Types of treatment facilities Some consider container-type treatment facilities to be the most rational.
All houses in cities and beyond have long been equipped with specialized communications. With the help of neither, the necessary comfort and such a necessary level of convenience of residents are provided. From all houses, large and small, runoff flows to wastewater treatment plants. There they are collected and processed.
Sewer networks of large city systems are combined with industrial ones. Modern systems of treatment facilities contain a whole range of enterprises that combine new technologies for the purification of polluted waters.
Residents of country houses, summer residents, owners of gas stations and car washes use local-type devices. Most often, residents of such houses organize drains using such types of treatment facilities:
container type.
Somebody think container-type wastewater treatment plant the most rational. They have a deep aerobic processing of fecal water. At the outlet of such a system, water comes out with a degree of purification of slightly less than one hundred percent. It can be taken to absolutely anywhere. Usually, water is dispersed in a special well with drainage and goes directly into the ground.
The sealed body of the container is made of polypropylene, which does not rot and does not enter into various chemical reactions with any of the components of wastewater in the sewer. This plastic perfectly withstands any temperature and is very durable. The manufacturer usually gives a good guarantee for their products. Inside such a case there are several compartments, five chambers and a compartment for compressor and automation equipment.
Wastewater treatment plant of the wave type.
They are used to purify storm drains, household and household waste, as well as effluents generated after washing cars at a car wash. Contaminated water is drained into a container, where it undergoes many purification steps in special filtration units. Water that has been purified is usually used for a second time or is discharged into a storm collector. The filter materials that are used at each stage of block cleaning are different, made of non-woven textile fibers of different composition.
Block-modular type.
They are classified as stormwater treatment plants and they consist of combined systems. Designed block-modular treatment facilities respectively for the treatment of wastewater from toxic chemicals and petroleum products. They are presented in the form of block boxes or block containers. Its body is made of steel with a special coating. It is insulated either with mineral wool, or with fiberglass or foam.
Approximately the same type block-type industrial treatment facilities.Two stages of treatment (physico-chemical and biological) make it possible to purify wastewater at enterprises to the norm and drain them into water bodies.
For the treatment of surface runoff from areas from 0.1 ha to 10 ha, we have developed treatment plants of the Volna-1 series according to TU 4859-003-68995916-2010 of ten standard sizes with a capacity of 1.0 m 3 /hour; 1.8m 3 / hour; 3.6m 3 / hour; 5m 3 /hour; 10m 3 /hour and 18m 3 /hour.
Technical characteristics of stormwater treatment plants of the "Volna-1" series.
Treatment plants "Volna" manufactured by Stroyspetsmontazh + 21 LLC TU 4859-003-68995916-2010 (TU 5265-002-18274347-2006), registered by the State Standard of Russia under No. 200/056578, have a valid Certificate of Conformity No. ROSS RU.AB75. H02587 (ROSS RU.AG40.H01182); Sanitary and epidemiological expert opinion No. 468-02-EZ (77.01.03.526.T.066192.10.06) and a positive conclusion of the State Ecological Expertise of the Federal Service for Ecological, Technological and Nuclear Supervision in the Central federal district(ROSTEKHNADZOR) under No. 02-EE-93237-06 dated 09/08/06, which they are recognized as standard.
The principle of operation of the treatment plant is based on mechanical methods wastewater treatment (14 technological transitions) without the use of chemicals. These are thin-layer settling, forced and non-pressure filtration on needle-punched bag filters with preliminary clarification of water in a hydrocyclone and an oil trap; sequential filtration on stuffed fine-fiber filters of three stages of purification; flotation using a vortex water-air ejector and subsequent free-flow filtration on synthetic non-woven materials, as well as post-treatment on carbon fiber sorbents.
The design of the treatment plant provides for the possibility of adjusting the loading of filter elements in terms of composition and volume at different stages of purification, which, without unnecessary costs, allows, based on water analyzes made during commissioning, to bring the degree of purification to the required standards, depending on the concentration of contaminants in the incoming effluents.
The treatment plant is manufactured at the factory (complete set) from steel 4-6 mm thick with internal partitions and filter frames, and is covered with a two-layer polymeric anticorrosive composition. All filter elements of domestic production are made on the basis of modern synthetic textile materials and activated carbon fibers.
Wastewater treatment plant operate in automatic water circulation mode and require only periodic monitoring. To do this, the external panel of the control unit is equipped with a light signaling the switching on and off of the pumps, as well as the degree of contamination of the filter elements. It is planned to switch the system to "manual" control of the operation of pumps in the event of a sudden loss of excess precipitation.
To ensure year-round operation (including during thaws), technological modules are mounted buried in the ground at the level of the design mark and closed with additional internal insulated covers; their side walls are insulated from the outside along the perimeter with extruded polystyrene foam 100 mm thick to the depth of soil freezing. In this regard, additional heating of the treatment plant and the construction of a warm building or pavilion above it are not required. All covers of the treatment plant are removable, which provides free access to any technological compartment and convenience during routine maintenance and removal of filtration products.
Installation of the treatment plant can be carried out by the Customer on their own according to the attached instructions.
Treatment plants "Volna-1" can be grouped during installation by several pieces with parallel connection to achieve a given total performance (for example, "Volna-1-18" + "Volna-1-18" = "Volna-1-36").

There are four complexes of treatment facilities on the territory of the enterprise. Treatment facilities No. 1 are designed to treat industrial effluents from car washing and consist of seven settling tanks arranged in series. Washing is carried out with recycled water (from the last sedimentation tank, water is pumped to the sink).
Complexes of treatment facilities No. 2 and No. 3 are located on two branches of storm sewers parallel to the coastline of the river. Moscow.
Each complex of treatment facilities consists of a mud trap, a sipron filter and an oil collector.
Pre-treated wastewater at treatment facilities No. 2 and No. 3 is pumped by a pump to a post-treatment unit of the “Volna” type (treatment facilities No. 4) and then discharged into the river. Moscow. The design capacity of the post-treatment unit "Volna" is 72.0 m3/day. Treatment facilities No. 2, No. 3 and No. 4 located outside the territory of the enterprise, but within the territory of the water protection zone of the Moscow River.
The enterprise designed, built and operates system No. 4 of storm and waste water treatment facilities (Fig. 2) consisting of:
cleaning unit "Wave" - 1 pc.;
receiving tanks - 2 pcs.;
intrasite networks;
submersible pump "Gnome-10" - 2 pcs.;
instrumentation system and A.
Cleaning method: mechanical, with elements: pressure filtration and sorption. Productivity up to 3 m3 per hour.
The concentration of contaminants in the incoming effluent:
- - suspended solids (V.V.) - up to 100 mg/l;
- - petroleum products (N.P.) - up to 20 mg / l.
Effluent concentration after treatment facilities:
V.V. - no more than 10 mg/l;
N.P. - no more than 0.05 mg/l.
Figure 2 - Technological scheme of the stormwater treatment plant "Volna"
Treatment plant "Wave" works as follows. Stormwater contaminated with suspended solids and oil products enters the receiving tank 1 along the natural slope of the territory or the storm-collecting chute (collector). A coarse filter installed in the receiving tank 1 prevents the removal of pollutants to the water intake area of the "dirty water" pump 2. Further, the clarified water is pumped for cleaning by the "dirty water" submersible pump 2 to the "Volna" purification unit 3. The pump is turned on automatically as it rises water level in the receiving tank 1 up to a certain mark; pump shutdown is also automatic when the level drops. The pressure pipeline is equipped with a gate valve to regulate the optimal performance of the cleaning unit and can be equipped with a check valve.
The Volna 3 purification unit is equipped with four successive stages of support filtration, made in the form of removable cassettes. The purified water after the last stage can be reused or discharged into a storm sewer.
The filter materials used at each purification stage of the Volna block differ from each other and are non-woven compositions made of textile fibers of various compositions:
- - Lavsanite
- - KM-1/400
- - KM-2
- - KM - 1/170
- - Sintenit-P
- - Carbon felt
- - Foam rubber.
The selection of filter materials, their volume and combination is carried out depending on the composition of the effluent in each case during commissioning and is specified during the warranty period of operation.
Over time, filtered sludge of finely dispersed suspensions accumulates at the bottom of the purification unit. To remove it and regenerate the filters, there are four valves located in the lower part of block 3. When they are periodically opened, the sludge flows down the pipeline to the sand area 4, where it is dehydrated and accumulated for disposal. The filtrate from the sludge, having passed the coarse filter, which is equipped with a sand platform, again enters the receiving tank 1 and enters for cleaning.
The city fecal sewerage is laid further than 500 m from the territory of the base of the Mechanization Department. Therefore, laying a domestic sewerage network from the base to the city network is an impractical and expensive construction. In this regard, the discharge of household water on the basis of the Mechanization Department is carried out into concrete storage tanks for storm water.
On the territory of the base there are two concrete reservoirs - a reservoir with a volume of 12 m3 (Fig. 3) and 8 m3, with metal caissons with very reinforced insulation nested inside.
Storm water treatment facilities are cleaned as they accumulate suspended solids and oil products. Suspended solids are removed and transported by pneumatic tank from the territory of the base in accordance with an agreement with CJSC Khoroshevskoye Road Administration.
At present, the wells are in a satisfactory condition. There are no complaints against the company for the untimely removal of fecal water.
