Description

The invention relates to the treatment of wastewater and can be used in the water treatment of return flow and irrigation systems for reuse for irrigation or drainage in the waters of the seas and reservoirs outside the zones of water use.

The purpose of the invention is to increase the efficiency of water treatment drainage water.

FIG. 1 shows the water intake of drainage and waste water of irrigation systems, plan; in fig. 2 is a section A-L in FIG. one.

The drainage-wastewater intake includes a dam 1, jetting dams 2, creating compartments 3 with close to zero bottom slopes and are equipped with water outlets-aerator 4, dams 5 embankments limiting the water intake area, drainage collector 6 and discharge channels 7, pumping station 8 transfering pump. - discharge flow, tray 9 for supplying drainage-waste water to the first compartment of the water intake through weirs 10 with a variable rowing row, having aerators 11, for example, as a cantilever discharge.

On the slopes of the dam and dams, a device 12 bioplats of higher aquatic vegetation (reed, reed, reed), providing biological treatment of drainage-waste water. Pump station 13 is designed to supply prepared for recycling drainage-discharge water to (Pipeline 14 in

The presence of a higher aquatic plant, 25 enrichment with oxygen when entering the compartments, adjustable speed of movement of the water in the compartments and its good warming contribute to the intensification of drainage cleaning in wastewater from harmful impurities.
