Elimination of Contamination Factors of Wastewater Deep Treatment in Steel Industry Coking Plants

A compound JA-450A/B composed of component A (FeSO4,K2FeO4,6%~8% high polymer flocculant,>3% FeCl3) and component B (H2O2,CaCl2,7%~8% AlCl3) was developed.Results showed that the JA-450A/B was effective for biochemical treated coking waste water.The decontamination efficiency of CODcr,total cyanide,fluoride and chroma was stable.Especially in highly contaminated raw water,the elimination of contamination factors by JA-450 A/B was more effective.
