摘要
介绍了好氧—兼氧—好氧系统处理氯碱行业电石渣上清液、助剂废水的工艺流程和处理效果。废水经处理后 ,进水COD从 1 0 0 0mg/L下降至 90mg/L以下 ,COD去除率平均为87.5 % ,BOD5去除率平均为 93 .3 % ,出水指标达到GB8978— 1
An aerobic facultative anaerobic aerobic system has been used in treatment of carbide slag supernatant and auxiliary wastewater in chloro alcali industry. The process flow and treatment effect are presented. After treatment, COD is reduced from 1000 mg/L to 90 mg/L with 87.5% of removal rate. The average removal rate of BOD 5 is 93.3%. The effluent can meet the first grade of the national discharge standards (GB8978-1996).
