摘要
萍钢焦化厂新建酚、氰废水处理站采用了先进的A/A/O法生物脱氮工艺,此工艺将污水二级处理中的缺氧、好氧两大类方法有机结合在一起,对焦化废水中的酚、氰、COD、氨氮等多种污染物均有较高的去除率,尤其是出水氨氮含量远远低于钢铁行业一级排放标准(15mg/l)。文章详细介绍了A/A/O生物脱氮的原理、运行控制和工艺流程。
Pingxiang Steel coke plant new phenol, cyanide wastewater treatment stations adopted advanced A / A /O biological nitrogen removal technology which combined anaerobic with aerobic ways . It remove effectively the coking wastewater phenol, cyanide, COD and ammonia nitrogen and other pollutants. Especially ammonia content in the effluent is far below the steel industry emission standard （ 15mg / 1）. The article dwells on the A / A / O biological nitrogen removal of the principle of operation and process control.
