| 摘 要： | 采用硫化反应、混凝沉淀工艺,对工业含汞废水进行脱汞实验研究。结果发现,将工业含汞废水的pH值调节到7～8,Na2S投加量为理论用量的14～18倍,再加入适量的混凝剂FeSO4,出水汞离子浓度即可低于国家排放标准(0.05×10-6)。

| Abstract: | The sulfuration-coagulation process is used to treat mercury-containing wastewater. The results show that under the conditions： pH of 7 - 8, Na2S adding amount of 14 - 18 times of theoretical amount, with appropriate coagulant FeSO4, the mercury concentration in discharging wastewater can meet the national standard （ 0.05 × 10^-6 ） . |
