摘　　要：采用铁盐与阴离子型PAM联合调质方式对给水厂排泥水进行调质试验。试验条件下,AN910PWG投加率为2‰,铁盐与其投加质量比为1时,调质后污泥絮体颗粒较大,沉速为3.18mm/s,污泥比阻为4×1011m/kg,上清液浊度为10NTU,与阳离子型FO4240SH投加率为4‰时的调质效果相当,但药剂费用节约显著。Jar test was carried out for waterworks sludge water condition by polyferric chloride combined with anionic PAM （AN910PWG）. Best dosage has founded, when AN910PWG dosage 2%0 and mass percent of polyferric chloride to anionic PAM 1 were applied, sludge floc of bigger size was observed in the conditioned sludge water and sediment velocity of 3.18 mm/s, SRF （sludge resistance of filtration） of 4×10^11 m/kg and effluent turbidity of 10 NTU were measured. These are similar to dosage 4%0 of cationic FO4240SH and will reduce the dosage.
