Abstract
The article raises the problem of treating the wastewater of the pig-breeding complex in classic fish-breeding and biological ponds. A waste water treatment scheme is proposed. Waste water treatment in fish-breeding and biological ponds is considered from the point of view of quality of hydrochemical and sanitary-bacteriological composition of treated waste water. The analysis of the obtained data showed that in the system of fish-biological ponds operating in a flowing mode, purification and decontamination of waste water coming from the pig-breeding complex to a stabilizing level takes place, fish are grown in the pond of clean water. Fish and biological ponds used in agriculture are characterized by high environmental and environmental-economic effect.
