摘　　要：文章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-的摩尔比值为1∶10,废盐酸循环时间为60 min时,处理后的盐酸汞浓度可降低到1 mg/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 is introduced on treatment of mercury - containing waste hydro- chloric acid with Hydrogen sulfide and efficient reactor. When Hg^2＋ and S^2- molar ratio is 1 ： 10, cycle time of waste hydrochloric acid is 60 minutes, mecury concentration of hydrochloric acid can be reduced to 1 mg/L. The technology has simple process, low operating cost and fine environmen-tal and economic benefits.
