The invention relates to the protection of waters, in particular to the prevention of pollution of surface waters surface water allocated to agricultural land.
During precipitation from the surface of agricultural land is washed away and carried into water bodies a significant amount of fine-grained soils, fertilizers, pesticides, residues of plants and the life aquatic organisms, as well as petroleum products. The intake of these substances in water bodies leads to pollution, deterioration of the oxygen regime and organoleptic characteristics of water.
A device for the mechanical purification of water (asscr No. 1481348, class E 03 F 5/14, 1987), comprising a housing, a shield, a controller, a rotating perforated drum, the mechanism of the cleaning blade and the wheel.
A disadvantage of the known system is the lack of purification from suspended solids, which can lead to blockage of the anterior chamber, and the presence of the gearbox, propeller shaft and a series of gears reduces the durability of the structure.
Most similar to that proposed by the technological nature is a system of storm water drainage (asscr No. 1142607, class E 03 F 5/10, 1983), containing take rain pit wells, collector probatova sewers and collector drainage of rain water in the reservoir, provided with a reservoir for cleaning threads with the containing a series of vertical partitions, dividing the enrollment, overflow and sucky camera, and the settling chamber is connected to the collector probatova sewage sludge pipeline.
A disadvantage of the known system is the cyclical nature of the work, resulting in the structure is large. In addition, through a tank of water purification are not all rain water, which makes it possible to discharge into the waters of pollutants.
The technical solution is to simplify the construction and increase the efficiency of purification of surface waters.
The task is achieved by a modular device for treatment of surface water allocated to agricultural land, including vertical septum, which divides it into reception, an overflow and a settling chamber, made of several similar sections, fitted with dividing camera, camera clean water chamber for collecting oil and floating debris, the device contains a filter dam installed on the bed of the recipient.
The novelty of the claimed proposal due to the fact that the modular device may contain any number of identical sections, allowing you to achieve different degrees of purification. Filtering the dam prevents streambed scour pond and serves as a base for roads and decimal surface runoff. At the same BP is me is so that has the ability to self-clean during the pass in the receiving waters of the flood costs. The location of the partitions below the plate prevents erosion of the road by the overflow of water through the device.
According to the patent and scientific literature not found a similar technical solution that allows to judge about the level of invention proposals.

After the clarified stream without suspended solids enters the separating chamber 5. Oil and floating debris float to the surface and flow by gravity into the chamber for collecting oil and floating debris 10 through the float valves 11, maintaining constant water level at the Weir - 4 mm. camera 10 of the settled water without oil and floating debris through the mine water discharged 12 enters the outlet chamber 13. The main part of the clarified stream from the separation chambers 5 through the vertical wall 7 and the camera clean water 9 flowing through the vertical wall 8 into the discharge chamber 13.
From the discharge chamber 13 through the filter dam 15 pure water to flow into the recipient 14.
Modular device for treatment of surface water allocated to agricultural land, including vertical walls, de is Asia it on admissions, overflow and settling chamber, characterized in that the device is made of several similar sections, fitted with dividing camera, camera clean water chamber for collecting oil and floating debris, the device contains a filter dam installed on the bed of the recipient.
