摘要:

以绿矾(FeSO4·7H2O)为药剂,对硫化物含量为1 571.86mg/L、pH为9.5的模拟含硫废水进行脱硫试验。结果表明,在废水初始pH值为10,反应温度为35℃,绿矾投加量为16g/L时,可获得最佳脱硫效果,废水中硫化物去除率达99.69%,出水硫化物含量降至4.83mg/L。

Abstract:

By taking green vitriol(FeSO4·7H2O)as chemical agent, desulfurization test is conducted for the simulating sulfur containing waste water with sulfide content of 1 571.86mg/L and pH value of 9.5. The result shows that when the waste water has the initial pH value of 10, reaction temperature is 35℃ and the adding amount of green vitriol is 16g/L,the best desulfurization result can be obtained. The removal rate of the sulfide in the waste water is up to 99.69% and the sulfide content in the waste water at outlet is reduced to 4.83mg/L.
