摘要
采用传统的活性污泥法处理焦化废水 ,很难达到理想效果。而运用厌氧—欠氧—好氧之生物处理法结合化学处理法 ,能使出水达到国家 GB9878- 1996一级排污标准。本方法具有工艺流程简单、操作简便、运行稳定的特点。本文就此方法的工艺条件及影响因素作一探讨。
It is very difficult to deal with the coking water by traditional method adopting active mud.If we combine biological treatment with chemical one,then the COD、NH 3 N of the waste water can reach the National GB8978-1996 blow down standard compared with the former,the new method is easy to handle and work steadly.The article tries to explain the influencing factors of the new technology.
