摘要: 水厂废水的综合处理与回用是我国供水行业的新趋势和节水目标所在，采用强化混凝技术进行水厂排泥废水的深度处理。通过混凝剂筛选实验和有机物表征确定最佳混凝剂为高效聚合铝(HPAC)，适宜投加量为650 mg/L。当混凝剂HPAC投加量为650 mg/L时，对COD、TOC、浊度和色度的去除率分别为82.5%、89.8%、95%和92.5%，相应的出水值分别为58 mg/L、8.46 mg/L、2.35 NTU、13度，COD满足《污水综合排放标准》（GB 8978-1996）的要求(COD≤100 mg/L)，同时实验结果显示聚合氯化铝（PAC）、HPAC、三氯化铁（FeCl3）主要去除分子量处于＞1 300 Da范围的有机物，对分子量处于744～1 300 Da之间的有机物去除有限。

Abstract: Integrated treatment and recycle of wastewater from water treatment plants becomes new trend and target to save water in water industry. The advanced treatment of filtrate from sludge water was tested by using enhanced coagulation. Results of jar tests and DOM characterization showed that HPAC was the optimum coagulant for filtrate treatment， and the proper dose was 650 mg/L. Removals of COD， TOC， turbidity and color were reached by 82.5%， 89.8%， 95% and 92.5% with a final value as 59 mg/L， 8.46 mg/L， 2.35 NTU and 13 degrees， respectively. The effluent COD meets the criteria of the Integrated Wastewater Discharge Standard (GB 8978-1996). Furthermore， the experimental results revealed that molecular weight (MW) of organics removed by polyaluminium chloride (PAC)， HPAC or ferric chloride were mainly ＞1 300 Da， while between 744～1 300 Da was only limitedly removed.
