FIELD: agriculture.
SUBSTANCE: invention relates to agriculture, in particular, to irrigated farming in recycling sewage and stock-raising effluents in a sprinkling system from distributing pipelines to agricultural irrigation fields (AIF). Area of mirror 3 of wastewater containment pond 4 over water areas of dams is divided into working sections with fixation of posts 5, to which network 1 with fixed elements in form of absorbing jaw 2 is fixed. Containment pond 4 is a closed water area with enclosing dam along its perimeter with zone of sludge accumulation from liquid drains. There is developed effective and economically accessible method for prevention of wastewater (livestock) evaporation from containment pond surface, based on the fact that containment pond 4 water mirror 3 is coated with mesh 1 with an absorbent material in the form of jaw 2 from foamed polyurethane. Grid 1 with absorbing jaw 2 is fixed on a block-rope structure having steel rings 7, through which iron ropes 6 are passed in one direction and the network is fixed to opposite shores of containment pond 4.
EFFECT: higher efficiency and reliability of protection of wastewater from lifting of biogas into atmosphere above area of mirror containment pond and simultaneously supply of wastes to agricultural irrigation fields.
