The invention relates to the field of construction and can be used for removal and cleaning runoff of rainwater, snow melt and sprinkling water from road, rail, built-up areas, industrial sites, etc.

A well-known system of drainage and treatment of surface runoff, including rainwater collector, settling chamber, a separating chamber with an input, an output and a lateral exit of the cleaned fluid, filter chamber and outlet manifold (see SU 1776636 A1, 23.11.92.).

The disadvantages of the known systems of drainage and treatment of surface runoff is the complexity of its design due to the presence of a large number of mechanical components, increasing the probability of failure, and reduce the quality of effluent treatment.

The closest in technical essence and the achieved result is a system of drainage and treatment of surface runoff, including water-insulated from the surrounding soil, consistently communicated between a drain manifold, a settling chamber, divided into two sections coarse and fine cleaning, respectively, biological pond, consisting of shallow bio Mesa and deep pools, tor (see EN 2137884 C1, 25.02.99. IPC 6 E 03 F 1/00).

The disadvantages of the known systems of drainage and treatment of surface runoff is that when the flow of surface runoff through the bottom of the bypass section of thin clearing settling chamber is clogged and the remaining impurities of surface runoff through the crest of the Weir, not after filtering, fall into a shallow plateau. In addition, the flow of surface water from the settling chamber in the biological pond occurs through drainage, podobravya channels and overflow tray, which complicates the design of the drainage system and cleaning and reduces the quality of cleaning runoff.

The present invention is to simplify the design and improve the quality cleaning runoff.

The problem is solved due to the fact that the system of drainage and treatment of surface runoff, including water-insulated from the surrounding soil, consistently communicated between a drain manifold, a settling chamber, divided into two sections coarse and fine cleaning, respectively, biological pond, consisting of shallow bio Mesa and deep pool next to the last filtered cameras which measures one of which is placed in the settling chamber between the sections of coarse and fine cleaning, and the other in front of the shallow bio Mesa, and each of the additional filter chambers are made from stacked layers from top to bottom of filter materials, reduction of permeability of each subsequent layer relative to the previous one, and the permeability of each layer chamber is not less than 1 m/day.

In the system of drainage and cleaning of the surface layer in additional filter chambers their vertical walls can be made of gabions and covered on the inner side of the geotextile.

In the system of drainage and treatment of surface runoff in each additional filter chamber, at least one of the upper layers can be made of gabions.

The system of drainage and surface runoff treatment can be provided for filtering the dam, installed in biological pond between shallow bio Mesa and plunge pool.

The technical result of the invention is to simplify the design of the extraction system and treatment of surface runoff and improving the quality of cleaning runoff.

In the drawing, the surface runoff includes seal from the surrounding soil consistently communicated between a drain collector 1, settling chamber 2, is divided into sections rough 3 and 4 thin cleaning accordingly, biological pond, consisting of shallow bio Mesa 5 and deep-basin 6, the filter chamber 7 is separated from the deep pool filter dam of 8, and outlet manifold 9. The system of drainage and cleaning of the surface layer provided with an additional filter chambers 10 and 11. Moreover, the filter chamber 10 is installed in the settling chamber 2 between the rough sections 3 and 4 thin clean, and the filter chamber 11 is installed in front of the shallow bio Mesa 5. Additional filtering chamber 10 and 11 are stacked layers of filter materials, the permeability of each subsequent layer to the previous one, starting from the top, decreases, but is equal to not less than 1 m/day. The vertical wall 12 additional filter chambers are made of gabions and covered on the inner side of the geotextile. Between shallow bio Mesa and deep pool has additional filtering dam 13.

The drainage system and cleaning runoff (rain, watering, melt water and other) works as follows.

Surface runoff Doge is indicate in a rough section of cleaning 3 settling chamber 2, where are exempt from large solids. Next, the surface runoff is filtered through an additional filter chamber 10 filled with layers of natural filter material, and into the fine purification section 4 settling chamber 2. With the passage of wastewater through the layers of natural filtering material additional filter chambers and their vertical gabion walls purification of wastewater from suspended particles and related products. The filtration coefficient of the natural filtering material covered in layers shall be not less than 1 m/day, which ensures maximum performance of the treatment plant of this type.

Use the filtering backfill with a smaller value of the coefficient of the filter will decrease the performance of the treatment plant and will require more frequent changing of the filter material and/or increase the size of the treatment plant.

In the fine purification section is the deposition of smaller impurities. From the fine purification section surface runoff is filtered through an additional filter chamber 11, which is also filled grained natural material with a coefficient filtersusa, planted with aquatic plants (macrophytes) one or more species: bulrush, cattails, reeds, sedges, pondweeds. In shallow bio Mesa is the biological decomposition of the oil contained in surface runoff associated compounds and heavy metal ions. The thickness of the water layer in the shallow bio Mesa above ground level must be at least 30 cm From the shallow bio Mesa surface run-off flow through the filter dam of 13, made of gabion structures in the deep pool 6, depth not less than 1 m In the deepwater bio Mesa processes of anaerobic decomposition of organic matter in wastewater and oxidized petroleum derivatives, as well as contact and accumulate heavy metals. In addition, in the water column there is a biological filtration of wastewater organisms of the zooplankton.

From the deepwater bio Mesa water being filtered by gabion filter dam, falls in full flow filter chamber 7 filled with natural sorbent, where the purification of surface runoff. Purified surface water flow from the filter chamber is discharged through the discharge call the nogo and rectangular. The gabions are filled with stone material basket, made of steel tightly galvanized mesh double twist hexagonal cells (cell size 100 x 120, 80 x 100 60 x 80 mm). This mesh is durable, resistant to corrosion and abrasion, durable, not spliced mechanical damage the individual wires.

Natural rock to fill gabions (crushed stone, gravel, small boulders, quarry stone) has a high density, durability, frost resistance. The size of the stone must be larger than the grid cell size that is 1.5-2 times. After the construction of gabion structures its open porosity is 30 %.
