摘　　要：研究泥渣回流强化混凝工艺对再生水的处理效果。研究结果表明，该工艺应用于再生水处理效果很好．在PAC投加质量浓度为10mg／L、回流泥渣质量浓度为10000～16000mg／L、干泥回流量为200mg／L时．泥渣回流强化混凝工艺对浊度、TP、PO4^3-、CODCr、色度及UV254的去除率分别为71．63％、71．21％、82．00％、36．62％、47．25％、18．85％。The treatment effect of the enhanced coagulation process by sludge refluxing on regenerated water has been studied. The results indicate that this process applied to the treatment of regenerated water has very good effectiveness. When the PAC dosage is 10 mg/L, the concentration of sludge refluxing is 10 000-16 000 mg/L, and the sludge refluxing volume is 200 mg/L, the removal rates of turbidity, TP, PO4^3-, CODCr, chroma and UV254 by this process are 71.63%, 71.21%, 82.00%, 36.62%,47.25% and 18.85%, respectively.
