摘　　要：焦化废水含有多种污染物,经过生化处理后,焦化出水往往还达不到国家规定的排放标准,需进一步进行深化处理。混凝剂HF-168系列药剂是通过药剂同水中的污染物起物理和化学反应,生成难溶于水的化合物析出沉淀,降低废水中的COD、总氰化物、浊度、色度等,使废水得到净化,达到排放标准。Coking wastewater contains many kinds of pollutants, often fails to meet na-tional standard at discharge after biochemical treatment and needs further treatment. Coagu-lant HF-168 makes physical and chemical reaction with pollutants in wastewater through chemical agents, which produces water insoluble compounds precipitating out to reduce COD, total cyanide, turbidity and chroma in the wastewater, making the wastewater purified and reaching discharge standard.
