净水厂沉淀污泥浓缩性能初探

Prior on the Sludge Thickening in Waterworks

对净水厂污泥的沉降性能及影响污泥浓缩性能的主要因素进行试验研究的结果表明 :污泥起始浓度是影响污泥浓缩性能的一个重要因素 ;对污泥进行慢速搅拌、酸处理。

The study was conducted on the sludge thickening properties and some factors that affect the sludge thickening in waterworks. The results show, the initial concentration of sludge is a very important factor to the sludge thickening properties. Beside this the thickening and dewatering properties of sludge also will be improved by means of slow agitating during the course of thickening, or treating by acid, alkaline, or polyacrylamide before the sludge enters the thickening tank. The results can be used as reference in the selection of sludge pretreatment methods and design of thickening tank in water works.
