摘    要:经浓缩的城市污水处理厂剩余污泥,一般是通过投加絮凝剂调质后进行机械脱水处理。絮凝剂品种选择、投加量多少都直接影响污泥的脱水效果,絮凝剂的费用也是污泥处理运行费用的重要组成部分。结合镇江污水处理厂污泥的产生、浓缩处理、脱水形式过程的生产实践,针对污泥的调质用絮凝剂的种类、用量等着手,进行絮凝剂的分析选择。提出了絮凝剂的选择应该遵循的原则以及确定污泥处理中药剂费的简易方法,同时建议城市污水处理厂在运行中应根据季节的变化调整絮凝剂用量。

关 键 词:污泥调质  絮凝剂选择  药剂费确定  生产实践  城市污水处理厂

Abstract:The thickened surplus sludge from municipal wastewater treatment plants is generally mechanically dewatered after regulated with flocculants and the type and dosage of flocculants will influence the dewatering effect directly.And the cost of flocculants is the main part of operating cost of sewage sludge treatment.With the processing practice on yields,thickening and dewatering pattern of Zhenjiang Wastewater Treatment Plant,the analysis and selection of flocculants are carried out with respect to the type and dosage of flocculants for sewage sludge regulation.the principles for flocculants selection and simple calculation method for chemicals cost for sludge treatment are proposed.It is suggested that the dosage of flocculants for sludge regulation should be adjusted in different seasons in real operation of the municipal wastewater treatment plants.
Keywords:sludge regulation  selection of polymeric flocculants  determination of chemicals cost  practice  municipal wastewater treatment plant
