The migration and distribution characteristics of the COD in the enriching process of HPF coking desulfurization waste solution

摘要：

　　The migration and distribution characteristics of the COD in the enriching process of Coking Desulfurization Waste Solution (CDWS) were researched in this paper.The results show that COD in the early and late condensate are all up to 10000mg/L and it is decreased at first and then increased in CDWS evaporating concentration process.This result is caused by substances containing organic at prophase and inorganic in the late.Therefore,removing the organic matter in the wastewater and controlling the temperature in CDWS concentrating process is the key to reduce the COD in condensate.
