摘要 水泥窑协同处置污水厂污泥避免了其他方式处置不彻底、存在二次污染等问题,是一种高效的污泥处置手段。污泥入窑前的干化脱水过程需要消耗大量的热量和电能,导致成本偏高。采用化学调质及机械压滤的深度脱水方式,先将污泥含水率降到55%以下,避开污泥的粘滞区,再采用废烟气余热进行干化,则可显著降低污泥脱水的成本。本文概述了国内外污泥化学调质的研究进展,分析了污泥深度脱水和普通脱水的区别,以期为污泥化学调质和深度脱水方法的选择提供参考。

Abstract: Sludge co-processing in cement kiln, compared to other disposal way, which avoids of incomplete disposal and second pollution, is an ideal way for sludge disposal. Before the  sludge  is fed into kiln, a drying pretreatment is necessary, which demands large amount of heat and electric energy resulting in huge operation cost. The water content of sludge is firstly reduced down to 55% which avoids of viscous zone by the deep dewatering pretreatment of chemical conditioning and physical press filter, then dried by the waste gas, this treatment process significantly  reduces the sludge dewatering cost. The progress in chemical conditioning of sludge was summarized in this paper and the difference of deep dewatering as well as regular dewatering are  analyzed in order to provide a reference for the adoption of sludge chemical conditioning and deep dewatering.
Key words:  sludge    chemical conditioning    deep dewatering
