| 无机混凝剂与壳聚糖联合调理对污泥脱水的影响 | |
| 摘 要： | 研究了无机混凝剂(PAFC和PAC)与壳聚糖(CTS)联合调理对污泥脱水效果的影响。结果表明:联合调理污泥脱水效果明显优于单一混凝剂调理。当无机混凝剂PAFC和PAC投加量(以干污泥量计)分别为60 mg/g,CTS投加量(以干污泥量计)为3.0 mg/g时,PAFC+CTS、PAC+CTS调理污泥比阻比原泥分别降低了87.90%和84.93%,滤饼含水率降到76.3%和76.9%,污泥平均粒径从原来的8.70μm分别增大至59.07μm和54.69μm。相同投加量下,PAFC+CTS联合调理的污泥脱水效果优于PAC+CTS联合调理。 |
