A disadvantage of the known installation is a great value at an insufficiently high efficiency and reliability.

The aim of the invention is to improve the efficiency and n is the plant stormwater treatment wastewater includes tank-averager block pre-treatment, treatment plant and pumping station, unit sorption filters and biological pond, reservoir equalizing tank and block prefilter made in the form of capacity, equipped with Pechorsky hopper, opening and flushing of sediment, the water mirror installed free-floating non-metallic pipe having perforations along its entire length 180 degrees of a circle in the bottom part and filled with a material with a developed surface and a high coefficient of the wetting liquid particles of oil.

This objective is achieved in that the installation of stormwater treatment wastewater treatment plants equipped with thin-film modules, shelves which are made of non-metallic pipes having perforations along the entire length of 150 degrees of a circle and placed unperforated side up, the pipe is filled with a material with a developed surface and a high coefficient of the wetting liquid particles of oil.

This objective is achieved in that the installation of stormwater treatment wastewater packetboy bunker block prefilter connected through a pump to output acrobat connected to the system opening and flushing of sediment input and the collector of sewage treatment plants.

This objective is achieved in that the installation of stormwater treatment wastewater release of treated water from the biological pond equipped sorption screen filter.

The drawing shows a schematic diagram of the installation of stormwater treatment wastewater volume, which is the subject of the present invention.

Installation of stormwater treatment wastewater contains a reservoir equalizing tank 1, block pre-treatment 2, treatment facilities 3 pumping station, unit sorption filters and biological pond (not shown).

Reservoir equalizing tank 1 and the block prefilter 2 made in the form of capacity, equipped with Pechorsky hopper 4, system 5 opening and flushing of sediment, the water mirror installed free-floating non-metallic pipe 6 having perforations along its entire length 180 degrees of a circle in the bottom part and filled with a material with a developed surface and a high coefficient of the wetting liquid particles of petroleum products. Treatment facilities 3 is equipped with thin-film modules 7, shelves which are made of non-metallic pipe 8 having along its entire length to 150 degrees of a circle and placed unperforated its hundred-and-the mi particles of petroleum products. Pechorsky hopper 4 block prefilter 2 is connected via the pump 9 to the inlet pipe 10 of hydrocyclones, slurry pipe 11 which is connected to the storage hopper 12 and the outlet 13 is connected to the system 5 opening and flushing and inlet manifold 14 treatment facilities 3.

The release of treated water from the biological pond equipped sorption screen filter (not shown).

The installation of stormwater treatment of wastewater is carried out as follows.

The first rainwater subject according to SNiP 2.04.03-85 cleaning, proceed to the reservoir equalizing tank 1 and the block prefilter 2. Sand and other solid particles settle in Pechorsky hopper 4, where the pump 9 are served in the inlet pipe 10 of the hydrocyclone, where the centrifugal forces are gathering and through the pipe 11 are displayed in the storage hopper 12. The clarified water through the pipe 13 is given partially in the system 5 for opening and flushing of sediment in the hopper 4, and the main part of the clarified water is fed into the treatment plant 3 through the inlet manifold 14. Particles of oil present in the purified water in the tank-the equalizing tank 1 and the block prefilter 2 b is a material with a developed surface and a high coefficient of wetting liquid particles of petroleum products, for example, polyethylene or polyamide.

Clarified waste water from the inlet manifold 14 is coming into the treatment plant 3, which pass between the shelves of thin-layer modules and proceed further through sorption filters in biological pond natural deep cleaning. With the passage of purified water between the shelves thin models 7 from a thread on the shelves of deposited solids (smaller fractions), where the accumulation slide down and eventually fall into the hopper 4, the fine particles of oil will float and through the perforation will go into the pipe 8, which will accumulate.

Periodically, 1-2 times per year pipes 6 and 8 are removed and accumulated them in the oil are removed by any known method.

The size of a gap between treatment plants 3 and bin 4 provides the drift of sediment and pass not more than ten percent of the flow of the purified waste water from reservoir 14.

The release of treated water from the biological pond equipped sorption screen filter, which increases the degree of purification of waste water from oil and prevents their release into the river in case of any emergency or abnormal situations.

The proposal is a modular version of the maximum factory readiness, that significantly reduces the amount of construction works and reduces their cost.
