净水厂排泥水及其污泥的处置

Disposal of Sludge Water and Sludge in Water Treatment Works

主要通过阐述净水厂排泥水及其污泥处置的必要性,对不同水源水质的排泥水组成及特性进行了分析,归纳并分析了目前国内外对净水厂排泥水的各种处理技术方案,指出净水厂沉淀池排泥水和反冲洗水处理方式需要经过技术经济论证而选用;最后在分析总结国内外净水厂污泥处置方式的基础上,提出污泥资源化是净水厂污泥处置的最终出路。

By discussing the necessity of the disposal of sludge water and sludge in water treatment works, this paper analyzes sludge water composition and properties of different water quality, summarizes all kinds of processing technology at home and abroad for muddy water in water treatment works and then points out that the treatment approaches for the Sludge water purification from sedimentation tank and backwashing water need to be selected after technical and economic argumentation. Finally, it proposes resource utilization as the ultimate way of sludge disposal in water treatment works on the basis of reviewing treatment sludge disposal methods both at home and abroad.
