Integrative treatment of wastewater and offal in broiler chicken slaughterhouse

Depending USB + contact oxidation method, a treatment station of waste water was set up. The construction and establishment in this research could decrease the COD、BOD₅、SS and the Oil and grease rate to 96.8%、99.6%、99.6% and 99.4%, and reduced the cost by 25%. Moreover, every index can reach GB 8978-1996 Waste water Comprehensive Emission Standard Level Ⅰand GB13457-92 Discharge Standard of Water Pollutants for Meat Packing Industry chicken slaughter production level Ⅰ.At the same time, the purified water with the treatment of the biotechnology method can reach the same level as the construction management technology. And it can reduce the cost for treatment by 85%.
