市政污泥深度脱水试验研究

The Study of Sewage Sludge's Deep Dehydration Performance by Experiment

随着污水量的快速增长,污泥产生量大幅增加,且大多未妥善处置。文章通过一系列试验,研究了几种通过添加有机药剂的方法,可以将污泥的毛细吸水时间大大缩短,从而使脱水性能大大提高。

As the quantities of treated sewage increasing, the quantities of sewage sludge are more and more. But the most of sewage sludge are not treated by proper way. By a series of experiment with a few of organic reagents added into the sludge, the author studied on changing of the CST （capillary suction time）, and found a proper way to increase the sewage sludge＇s dewatering performance.
