This article highlights the composition of wastewater from poultry farms and their suitability for irrigation of agricultural crops. It has been established that the chemical demand of wastewater from poultry farms is 480–850 mg О2/l, which indicates a high level of contamination with organic products. Coarse and finely dispersed substances vary within 430–720 mg/l, and biochemical oxygen consumption on the fifth day (BOD5) within 0.39–0.74 g О2/l, and at the time of mass effluent emissions it reached 15–1.6 g О2/l. The titer of Escherichia coli was equal to 10-6, the number of microbes ranged from 48.5 x 106 to 61.6 x 106. Determination of the suitability of wastewater based on generally accepted methods showed that they are quite suitable for irrigation of crops without additional reclamation measures.
