%X 本文论述了碱性氯化法–络合沉淀法处置高浓度含氰废液的实验研究，并进行了双氧水氧化法、硫酸亚铁法、碱性氯化法处置含氰废液的实验效果对比，研究表明碱性氯化法–络合沉淀法处理含氰废液时，氰化物去除效率高，出水可达到排放标准，即氰化物含量小于0.5 mg/L。实验考察了体系的pH值、氧化还原电位(ORP)、反应时间、络合剂对含氰废液中的氰化物指标降解的影响，确定碱性氯化法–络合沉淀法处置高浓度含氰废液的最佳条件。<br />
This paper discusses the pretreatment technology of high concentration cyanide-containing waste liquid by alkali chlorination and complexation precipitation. The cyanide removal efficiency is high and the effluent can meet the discharge standard of cyanide-containing waste liquid. The effects of pH value, REDOX potential (ORP), reaction time and complexing agent on the degradation of cyanide index in cyanide-containing waste liquid were investigated. The optimum conditions for disposal of cyanide-containing waste liquid by alkali chlorination and complexation precipitation were determined.
