摘要
给水厂污泥经浓缩处理后含水率仍然较高,需对其进行调质、脱水处理以缩小污泥体积,达到运输和处置的要求。简述了影响污泥脱水性能的因素,介绍了污泥调质剂的种类、调质机理和主要的调质方法及其应用。
The water content of water treatment plant sludge disposed by thickening tank is still high. In order to reduce sludge volume, the sludge need to be disposed by conditioning and dewatering system to achieve the requirement of transportation and disposal. This paper briefly described the factors of dewatering property of the sludge, and introduced the varieties of sludge coagulant, conditioning mechanism, conditioning methods and their application.
