Abstract: This paper mainly introduces the operation impact on coke oven，decanter，alkali adding
of ammonia stripper and other equipment on COD content of stripped water. COD content in stripped
water is reduced significantly by taking targeted measures，which helps to guarantee long-term stable
operation of biochemical system，bringing great environmental be nefits.
