摘　　要：根据九龙江流域给水厂污泥的颗粒性质,进行絮凝、污泥比阻和过滤试验,研究污泥的脱水性能。试验结果表明,适当投加聚丙烯酰胺可以降低污泥比阻,改善脱水性能。其中阴离子型聚丙烯酰胺对该地区水厂污泥的调理效果较好,PAM投加范围以低于0.5‰为佳,不仅可以降低运行成本,而且在改善污泥的脱水性能及上清液水质的回用效果上,均可以达到最佳的状态。The dewatering property of sludge discarded from waterworks in Jiulongjiang River Basin is researched by means of flocculent, specific resistance and filtration experiments on the basis of the granular characteristics of the sludge. The results have shown that adequate dosage of polyacrylamide (PAM) can reduce the specific resistance and improve the dewatering property of the sludge. And for this, the dosage of anionic PAM less than 0. 5‰ might be the best. It will be optimum way of economical and helpful to improve the dewatering property of the sludge and the reuse of the supernatant in sludge thickening.
