高效微生物—A/O工艺处理化工综合废水

High Solution Bacteria-A/O Process for Treatment of Chemical Integrated Wastewater

采用高效微生物—A/O工艺处理化工综合废水,出水氨氮可降到15 mg/L以下,在线监测出水氨氮平均值为0.4 mg/L,去除率高达99%;出水COD可降至100 mg/L以下,在线监测COD平均值为35 mg/L,去除率高达96%,上述两项指标均达到《污水综合排放标准》(GB 8978—1996)的一级标准。

The combined process of high solution bacteria（HSB）and A/O was used to treat the chemical integrated wastewater. The effluent ammonia nitrogen can be reduced to less than 15 mg/L, the on-line average monitoring value is 0. 4mg/L, and the removal rate is 99%. The effluent COD can be reduced to less than 100 rag/L, the on-line average monitoring value is 35 rag/L, and the removal rate is 96%. Both indexes meet the first criteria specified in Integrated Wastewater Discharge Standard （GB 8978 - 1996 ）.
