摘要
研究阴离子聚丙烯酰胺(APAM)对黑河水库高浊度水的絮凝特性,探讨APAM对使用聚合氯化铝(PAC)和水玻璃(PSI)助凝剂净水工艺的强化混凝作用,考察了在一定原水浊度下使用APAM对PAC和PSI投加量的影响。结果表明:原水浊度在1 000 NTU以下时,投加PAC之后加入APAM能起到强化混凝的效果。原水浊度在250 NTU时,投加0.2 mg/L APAM可将PAC和PSI投加量分别降低16.0和7.0 mg/L,且对浊度、色度、UV_(254)的去除效果相当。
The flocculation characteristics of anionic polyacrylamide(APAM) on high turbidity water of the Heihe River reservoir were investigated, and its enhanced coagulation effect on water purification process using polyaluminium chloride(PAC) and coagulant aids sodium metasilicate(PSI) was discussed, and the effect of APAM on the dosage of PAC and PSI under a certain raw water turbidity was investigated. The results showed that when the turbidity of raw water was less than 1 000 NTU, dosing PAC and APAM could enhance coagulation. When the turbidity of raw water was 250 NTU, adding 0.2 mg/L APAM could reduce the dosage of PAC and PSI by 16.0 and 7.0 mg/L respectively, and had the equivalent removal effect on turbidity, chroma and UV_(254).
