METHOD FOR TREATMENT OF LIVESTOCK EFFLUENTS OF PIG-BREEDING COMPLEXES AND FARMS FOR AGRICULTURAL USE Russian patent published in 2018 - IPC C02F1/52 C02F1/58 B01D21/01 C02F101/30 C02F103/20 

FIELD: agriculture.

SUBSTANCE: invention can be used in agriculture for treatment of effluents of pig-breeding complexes and farms for irrigation and fertilization of agricultural lands. For the implementation of the method, cattle-water drains are pre-acidified with a solution of phosphogypsum with a dose of 10÷45 mg/dm³, and then treated with a solution of aluminosilicate coagulant based on nepheline with a dose of 5÷20 mg/dm³ Al₂O₃, while pH is maintained in the range of 6.5÷7.5. Then liquid and solid phases are fed for disinfection and deodorization with Microzyme™ with a dose of 20÷40 mg/dm³. Precipitate is used as an organomineral fertilizer.

EFFECT: method ensures the acceleration of the settling process of a mixture of liquid waste and reagents, a reduction in the consumption of coagulant, preservation of the fertilizer value of the resulting sludge, utilization of effluents of pig-breeding complexes.
