摘要
采用接触氧化—水解 (酸化 )—两段接触氧化—混凝工艺处理高浓度养猪场废水 ,通过试验得到最佳工艺参数。在最佳试验条件下 ,进水 CODcr小于 50 0 0 mg/L,经处理后出水 CODcr平均去除率大于 97% ,BOD5 去除率大于 98% ,氨氮去除率大于 96 % ,各项主要指标可达污水综合排放标准 (GB8978— 88)
Biological contact oxidization hydrolysis(acidification) two stage biological contact oxidization coagulation process was used to treat high concentration piggery wastewater.The results showed that under the optimum conditions,when CODcr of influent was below 5000 mg/L,the CODcr,BOD 5 and NH 4 N removal efficiencies were 97 %,98 % and 96 % respectively.The effluent could meet the National Discharge Standard of China.
