摘　　要：通过对驯化后的某城市污水处理厂消化污泥的静态实验,运用正交分析法分别确定了阳离子聚丙烯酰胺、聚氯化铝和聚氧化乙烯与粉煤灰在处理垃圾渗滤液形成厌氧颗粒污泥时的最佳浓度,并用区域沉淀速度、污泥容积指数及上清液中的悬浮固体浓度评价了投加絮凝剂与粉煤灰后所形成的生物絮体的沉降性能．研究结果表明,通过对消化污泥驯化可将 COD去除率提高45％;阳离子聚丙烯酰胺与粉煤灰的最佳浓度组合为50 mg/L和200 mg/L, 聚氯化铝与粉煤灰的最佳浓度组合为40 mg/L和200 mg/L,聚氧化乙烯与粉煤灰的最佳浓度组合为10 mg/L和100 mg/L．The objectives of this study are laid on determining the optimal concentrations of Cationic Polyacrylamide, Polymerized Aluminium-Ferrum Chloride, Poly Ethylene Oxide and fly ash about the formation of anaerobic granular sludge in the treatment of landfill leachate through quadrature analytical method respectively, and also on appraisal of the settling performances of bioflocculates formed after the adding of flocculant and fly ash by using zone settling velocity （ZSV） , sludge volume index（SVI） and mixed liquor suspended solid （MLSS） concentration, according to static experiment of acclimated digest sludge from the waste water plant. The results show that the COD removal rate of acclimated digest sludge is enhanced 45%, the optimal concentrations of CPAM and fly ash are 50 mg/L and 200 mg/L, the optimal concentrations of PAFC and fly ash are 40 mg/L and 200 mg/L, and the optimal concentrations of PEO and fly ash are 10 mg/L and 100 mg/L.
