钢铁行业焦化废水深度处理中污染因子的去除

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

开发了一种JA-450A/B复合药剂,主要由A组分(FeSO4,K2FeO4,6%～8%高分子絮凝剂,不低于3%的FeCl3)和B组分(H2O2,CaCl2,7%～8%AlCl3)组成。其对经过生化处理的焦化废水中污染因子的去除非常有效。对废水中的CODcr、总氰、氟离子、色度的去除效率稳定,尤其在原水中污染因子含量较高时的去除率更为突出。

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.
