摘要
针对含氟高浊矿井水,采用聚合氯化铝(PAC)、复配酸性除氟剂(MT-701)、改性铝铁硅聚合物除氟剂(GMS-F6)和复合除氟剂(DAMW-03)四种药剂进行试验研究。结果表明:四种药剂对矿井水浊度的去除都可以超过97%,但PAC和MT-701仅可将矿井水氟化物浓度降至1.2 mg/L和1.3 mg/L;DAMW-03的除氟效果优于GMS-F6,在添加量为140 mg/L的条件下,氟化物浓度分别降至0.83 mg/L和0.95 mg/L;在DAMW-03添加量为120 mg/L、絮凝剂(PAM)添加量为1.0 mg/L、搅拌速度为150 r/min、搅拌时间为60 min、pH为6~7的条件下,氟化物浓度可降至0.95 mg/L。
To treat mine water containing fluorine and high turbidity,polyaluminium chloride(PAC),compound acid fluoride remover(MT-701),modified aluminum iron silicon polymer fluoride remover(GMS-F6)and composite fluoride remover(DAMW-03)were tested.The results showed that more than 97%of the turbidity of mine water could be removed by four agents.However,PAC and MT-701 could only reduce the concentration of fluoride to 1.2 mg/L and 1.3 mg/L respectively.The fluoride removal effect of DAMW-03 was better than that of GMS-F6.When the addition amount was 140 mg/L,the fluoride concentration was reduced to 0.83 mg/L and 0.95 mg/L after treated by DAMW-03 and GMS-F6,respectively.The fluoride concentration was reduced to 0.95 mg/L when the dosage of DAMW-03 was 120 mg/L,the dosage of flocculant(PAM)was 1.0 mg/L,the stirring speed was 150 r/min,the stirring time was 60 min and the pH was 6~7.
