METHOD OF CLEANING OF CATTLE-BREEDING DRAINS VERSATILE BY OBTAINING ENERGY AND FERTILIZERS AND DEVICE FOR ITS REALIZATION

摘要

1. A method for cleaning livestock waste to obtain energy and fertilizer comprising the primary condensation using the solid fraction for the preparation of fertilizer, anaerobic treatment with the formation of biogas, the provisional and final aerobic treatment to form a sludge, the aerobic pre-treatment of the liquid fraction ensures that the temperature anaerobic recycling the excess activated sludge in the removal of biogas and not less than 50% impurities, the final aerobic treatment secu echivaet removal of residual contaminants to established standards, characterized in that the surplus sludge gravitational sequentially subjected to primary sealing, heat treatment lasting at least 0.5 h in the temperature range 100-200 ° C and a secondary seal to the gravitational humidity not higher than 85%, at least a portion of the supernatant from step gravitational secondary seal in conjunction with the liquid fraction is directed to anaerobic treatment, the supernatant from step gravitational primary Nogo seal directed to the final aerobic treatment, and for the preparation of a mixture of solid fertilizer fraction after thermophilic aerobic treatment lasting at least 6 hours with the temperature reaching at least 50 ° C and activated sludge after the secondary gravitational uplotneniya.2. An apparatus for implementing livestock wastewater treatment method to obtain energy and fertilizer, consisting of successively connected to each other primary thickener pretreatment aeration tank, the aeration tanks
