SYSTEM OF IRRIGATION WITH CATTLE BREEDING WASTEWATERS Russian patent published in 2016 - IPC A01C23/04 A01G25/06 A01G25/09 F16K7/17 F16L55/10 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture and can be used as a combined system of irrigation with cattle breeding wastewaters along furrows and by sprinkling. System comprises a supply line - of pressure main pipeline 1 of a higher order. Distributing pipelines 4 are equipped with vertical metal posts 5 at construction of the irrigation system. Lower end of metal post 5 is rigidly connected to distributing pipeline 4, and its upper end is equipped with horizontal pressure branch pipe 10, outlets of which are connected via curved polyethylene pipe 11 with controlled valves 12 and 13 to irrigation pipeline 6. Polyethylene irrigation pipelines 6 are configured as assembly 7 in the form of water outlet 8 with the upper end tightly closed with flexible diaphragm 9 covering water outlet 8 discharge into soil (in the idle state). Distributing pipeline 4 is simultaneously a transporting and an irrigating one, for this purpose it is equipped with pressure hydrants 15 for connection of sprinkling machine 16, and they are arranged between vertical posts 5 with horizontal branch pipes 10. Irrigation pipelines 6 are installed, respectively, perpendicular to straight distributing pipeline 4. Wastewaters are supplied under pressure of the pump station into the supply line of main pipeline 1, then into distributing pipeline 4, into irrigation pipelines 16 with water outlets 8 overlapped ontop by flexible diaphragms 9. As the result of a combined process scheme of irrigation with wastewaters there is simultaneous supply of a preset standard of wastes into vertical posts 5 or hydrants 15, which is linked as per the plan to a specific technology of irrigation. Wastewaters leaving water outlets 8 with diaphragm 9 first wet the soil, and then form a funnel of washing with outlet of the wastes into furrows considering the width of spacing crops.

EFFECT: invention improves sanitary conditions of operating water sorption fields and provides ecological compatibility of cultivating agricultural crops, as well as reduced expenditures for construction and operation of the irrigation system.
