摘　　要：介绍了硫化氢法结合高效反应器处理含汞废盐酸新工艺。当Hg2+与S2-的摩尔比为1∶10、废盐酸循环时间为60min时,处理后的盐酸含汞质量浓度可降至1mg/L。该工艺流程简单,运行成本低廉,具有较好的环保效益和经济效益。A new technology was introduced on the treatment of mercury-containing waste hydrochloric acid with hydrogen sulfide in an efficient reactor.When the molar ratio of Hg2＋to S2-was 1∶10,the cycle time of waste hydrochloric acid was 60minutes,the mecury concentration in the treated hydrochloric acid was lowered to 1mg/L.The process was simple,low in operating cost,and had good environmental and economic benefits.
