铅锌选冶废水氟的去除研究
|
摘要
对4种不同的铅锌选冶含氟废水分别采用不同工艺流程和不同药剂进行了除氟处理。试验结果表明,某矿山井下水,当药剂HQF1用量为0.5 kg/m~3时,含氟量可从15.4 mg/L降至1.8 mg/L,除氟率达88.3%;某选矿厂尾矿水,石灰300 g/m~3,聚合氯化铝PAC的用量1 700g/m~3,氟可以从8.4 mg/L降至2.2 mg/L,除氟率可达到73.8%;某冶炼厂污酸,药剂HQF1用量为25 kg/m~3时,含氟量可从2 283 mg/L降至260 mg/L,除氟率达88.6%;某冶炼厂新液,药剂A+B组合用量20 kg/m~3时,含氟量可从171 mg/L降至51 mg/L,除氟率达70.1%。
Four kinds of fluoride-containing wastewater from lead-zinc metallurgy were treated with different processes and different chemicals respectively. The results show that when the dosage of medicament HQF1 is 0.5 kg/m~3, the fluorine content in mine water can be reduced from 15.4 mg/L to 1.8 mg/L, and the fluoride removal rate can reach 88.3%; when the dosage of poly aluminum chloride(PAC) is 1700 g/m~3, the fluorine content in tailing water can be reduced from 8.4 mg/L to 2.2 mg/L, and the fluoride removal rate can reach 73.8%; when the dosage of HQF1 is 25 kg/m~3, the fluoride content can be reduced from 2283 mg/L to 260 mg/L, and the fluoride removal rate can reach 88.6%; when the dosage of medicament A+B is 20 kg/m~3, the fluoride content in smetter new solution can be reduced from 171 mg/L to 51 mg/L, and the fluoride removal rate can reach 70.1%.
