摘要：

经筛选、驯化培养得到的高效微生物对污染物具有较强的耐受力和降解能力,应用O-A-O处理工艺,合理控制流程,在不外加碳源情况下,成功地将焦化废水中的氨氮从600￣800mg/L降到15mg/L以下,氨氮去除率达到了95%￣98%,总脱氮率也达到了80%以上,并且出水COD基本维持在100mg/L以下,达到了国家一级排放标准。

Abstract:

Highly efficient microbes have higher endurable capacity for pollutants and to decompose them more efficiently. With O - A - O process, highly efficient microbes can reduce NH₃ - N in coking-plant wastewater from 600 - 800 mg/L to 15 mg/L with removal rate up to 95% - 98% without adding organic matter. COD in effluent is less than 100 mg/L.

Key words: highly efficient microbes, coking-plant wastewater, biological denitrogenation, nitrification and deni-trification
