SEWER OF HYDROTECHNICAL AMELIORATION SYSTEMS Russian patent published in 2003 - IPC

FIELD: agriculture, particularly, irrigated agriculture in utilization of drainage water of hydrotechnical systems with horizontal drainage. SUBSTANCE: sewer includes entrance channel with transmitters of mineralization and volume of drainage water, channel has forebay provided with intake regulating structures with actuating mechanisms electrically connected to transmitters of mineralization and volume of drainage water. Sewer also includes discharge channels with units for chemical control of quality and purification of drainage water from pesticides, biogenic substances, heavy metals, and compartments with antifiltering coating for differential accumulation of drainage water depending on value of its mineralization. Sewer has interception channels and compartment for compartments of thaw and rain water. Sewer compartments are hydraulically interconnected by means of structures in order of increase of mineralization of drainage water and provided with pumping stations with conveying lines for supply of drainage water to users, and plant for preliminary desalination of drainage water with maximum mineralization. In natural evaporation of drainage water with maximum mineralization, compartment for its accumulation is made in form of natural evaporator accumulation is made in form of natural evaporator and has horizontal leveled bottom. EFFECT: higher efficiency of sewer functioning, reduced expenditures for desalination of drainage water. 6 cl, 5 dwg
