有机高分子絮凝剂对污泥脱水性能的影响研究

Research on the Effects of an Organic Macromolecule Polymeric Flocculant on Sludge Dewatering Performance

通过对城市污水处理厂污泥进行絮凝、污泥比阻和过滤实验,研究聚丙烯酰胺作为絮凝剂对污泥脱水性能的影响。实验结果表明,适当投加絮凝剂可以降低污泥比阻,改善脱水性能。

The effects of the different polyacrylamides as flocculent on sludge dewatering are analyzed based on the experiments of sludge flocculated,the determination of sludge specific filtration resistance（SFR） and the test of sludge filtration.The results show that properly adding flocculent will reduce SFR and improve the sludge dewatering performance.
