Research On Chemically Enhanced Flocculation Treatment Of Coking Wastewater

Coking wastewater is a kind of intractab wastewater which are from the process of making coke, purifying coal gas and recovering coke products. The component of this wastewater is complicated and is influenced by many kinds of factors such as the properties of raw coal ,the technology of coking and recovery of coke products,etc. There are many methods to treat the coking wastewater, among which chemically enhanced flocculation has been used for advanced treatment of coking wastewater. This article introduces the coking wastewater treatment situation of our country ,and puts great emphasis on the research on possibility and usefulness to the primary treatment of coking wastewater by chemically enhanced flocculation .Chemically enhanced flocculation treatment is to intensify the removal of pollutant by increasing flocculant under the foundation of primary...
