摘要
采用硫化反应、混凝沉淀及活性炭吸附工艺,对节能灯行业的含汞废水进行试验研究。结果发现,对Hg2+浓度为1.6mg/L的原水,将废水pH值控制在7～8,FeS、PAC及活性炭投加量分别为1.5mg/L、50mg/L和60mg/L时,出水Hg2+浓度为8μg/L,去除效率达到99.5%。
Sulfuration-coagulative precipitation-charcoal adsorption process is tested to treat mercury-contained wastewater on energy-saved light industry.The results show that under the condition pH= 7-8 FeS=1. 5mg/L、PAC=50mg/L、GAC= 60mg/L,the quality of effluent is 8μg/L and removal rate of 1.6mg/L mercury is over 99.5%.
