摘要：

采用铁碳微电解工艺深度处理阿维菌素废水好氧出水。结果表明，当好氧系统二沉出水COD为1 000 mg/L时，在停留时间为1 h，进水pH为2.5，混凝pH为6，溶解氧为0.9~1.4 mg/L的最佳工艺条件下，COD去除率达到56%。铁碳微电解法适用于处理阿维菌素废水好氧出水，该方法COD去除率高，运行稳定，操作简单。

Abstract:

The iron-carbon micro-electrolysis process has been applied to the treatment of aerobic effluent from avermectin wastewater. The results show that when the optimum conditions are as follows:COD of secondary sedimentation effluent is 1 000 mg/L,HRT l h,influent pH 2.5,coagulation pH 6,and dissolved oxygen 0.9-1.4 mg/L,the COD removing rate reaches 56%. The iron-carbon micro-electrolysis method is suitable for treating the aerobic effluent from avermectin wastewater. This method is characterized by high COD removing rate,stable running,and simple operation.

Key words: avermectin wastewater, iron-carbon micro-electrolysis, advanced treatment
