摘　　要：调查某地3座污水处理厂脱水污泥的7类有机污染物指标,对照城市污水处理厂污泥处置相关标准,针对污泥中不同污染物含量,提出污泥处置优化对策。在某地污水处理厂脱水污泥有机污染物中,总氰化物标准含量比值最高,可吸附有机卤化物含量比值较高;挥发酚含量较低但仍不符合农用标准,导致脱水污泥无法农用且无害化、资源化、减量化处置受限。目前某地污水处理厂现有污泥处理处置方式基本可行,但要防范部分污泥长期堆置导致的环境风险。The indexes of seven kinds of organic pollutants in dewatered sludge of three sewage treatment plants in one city were investigated,and the further optimization countermeasures for sludge disposal were put forward according to different pollutant contents in sludge according to the relevant standards for sludge disposal of urban sewage treatment plants.The total content of organic components in the dewatered sludge of one sewage treatment plant is the highest relative to the sludge disposal standard,followed by the content of adsorbable organic halides,which is relatively high,and the content of volatile phenol is very low,but it still does not meet the agricultural standard,which directly leads to the fact that the dewatered sludge can not be used for agriculture,and limits the harmless,resource and reduction disposal of dewatered sludge.At present,the existing sludge treatment and disposal methods of one sewage treatment plant are basically feasible,but the stacking of sludge will increase the environmental risk for a long time.
