摘要

以低浊微污染配水为试验水样

对比考察了硫酸铝(Al2(SO4)3)、氯化铝(AlCl3)和聚合氯化铝(PACl)的混凝效能;考察高锰酸钾(KMnO4)对铝盐混凝剂的助凝效果及对出水中残余颗粒铝(AlP)和溶解铝(AlD)含量的影响;并对残余铝形态与除污染效果的相关性进行分析。结果表明:AlCl3、Al2(SO4)3混凝效能相似

二者电性中和能力较PACl强

但去除浊质及溶解性有机物效果不如PACl。KMnO4对AlCl3、PACl絮体zeta电位的影响随其投量的增加有小幅下降

同时

KMnO4能有效地降低出水中剩余浊度与溶解性有机物含量

对AlCl3、PACl的助凝作用主要体现在电性中和阶段。KMnO4也能有效地降低出水中AlP与AlD含量

且残余铝多以AlP的形式存在

AlD含量相对较低;相同混凝剂投量下

AlP与剩余浊度存在一定的正相关性

而残余AlD含量受KMnO4以及铝盐混凝剂投量的双重影响。以网捕卷扫为主导时

AlD含量较稳定

在较小范围内波动。

Abstract

For treatment of light pollution water with low turbidity

the investigation was made on coagulation efficiency of Al2(SO4)3

AlCl3

and PACl as well as effect of potassium permanganate on efficiency of alum-based coagulants and on content of residual particle aluminum(AlP) and dissolved one(AlD)

and a relativity analysis also made on between form of AlP and removal performance.The results show that there is similar coagulation efficiency for Al2(SO4)3 and AlCl3

because their ability of charge neutralization is better than PACl.However

for removal of turbidity and dissolved organics

PACl is better than Al2(SO4)3 and AlCl3.The effect of KMnO4 on zeta potential of AlCl3 and PACl flocs weakens gradually with increase of its dosage

while that of KMnO4 on removal of turbidity and dissolved organic matter goes up

mainly in the stage of charge neutralization.Moreover

the content of AlD and AlP

mainly AlP

decreases obviously by use of KMnO4.At the same dosage of these coagulants

there is a positive correlation between the content of AlP and residual turbidity

but content of AlD is influenced by dosage of both KMnO4 and coagulants

especially

is relatively stable when sweep flocculation is in the ascendant.
