摘　　要：本文分析了上海市周边使用的生活污水处理装置产生污泥的性质,并将其与城镇污水处理厂剩余污泥进行对比。结果发现,农村分散式生活污水处理装置产生的污泥,其各样本的重金属和营养指标差异性较大;其均匀混合样本中的重金属和营养指标可以达到《城镇污水处理厂污泥处理农用泥质》(CJ/T309—2009)要求。This paper analyzes the nature of sludge produced by domestic sewage treatment plants used in Shanghai and compares it with the excess sludge of urban sewage treatment plants.The results showed that the sludge produced by the rural decentralized domestic sewage treatment plant had a large difference in the heavy metals and nutrient indexes of each sample;the heavy metals and nutrient indicators in the uniformly mixed sample can meet the requirements of“Sewage Treatment Plant Sludge Treatment Agricultural Mud”(CJ/T 309-2009).
