摘要

本文采用高效澄清与叠螺脱水组合工艺对自来水厂排泥水进行处理,对该工艺试运行期间,出泥含水率达不到设计目标80%情况下,调查分析不达标原因,并制定一些列改进措施。结果表明,通过延长前端排泥水进水混合时间,更换定制螺旋轴,调整浓缩段环片间隙,选择匹配度良好的絮凝剂(PAM)阴阳离子药剂,调整出泥压板间隙,调低叠螺机运行频率,增加投药量等一系列措施能降低排泥水处理后出泥的含水率,使污泥含水率稳定达标,证实本研究在自来水厂排泥水处理应用中具有较强的推广价值。

Abstract

In this paper, the combination process of high efficiency clarification and snail dewatering is used to treat the sludge discharge water of waterworks. During the trial operation of the process, the water content of sludge discharge is less than 80% of the design target, and the causes are investigated and analyzed, and a series of improvement measures are made. The results showed that a series of measures, such as extending the mixing time of the front-end sludge discharge water, changing the customized spiral shaft, adjusting the gap between the ring pieces of the enrichment section, choosing the PAM with good matching degree, adjusting the gap between the mud discharge plate, reducing the operation frequency of the screw stack machine, increasing the dosage, etc. could reduce the water content of the sludge discharge water treatment and make the sludge water content reach the standard stably. It is proved that this study has strong popularization value in the application of sludge discharge water treatment in waterworks.

Key words: water works; sludge water; water content of sludge; improvement measures
