涡流澄清池/纤维束滤池组合工艺在中水处理厂的应用

Application of Combined Process of Vortex Clarifier and Fiber Bundle Filter in Reclaimed Water Treatment Plant

徐州某污水厂采用涡流澄清池/纤维束滤池组合工艺对污水厂二级出水进行深度处理,当进水COD为60 mg/L、浊度为15 NTU时,出水COD和浊度分别约为30 mg/L和2 NTU,出水水质达到设计要求。实践表明,该组合工艺具有混凝效率高、过滤效果好、出水水质优、适应能力强等优点,具有一定的推广价值。

The combined process of vortex clarifier and fiber bundle filter was used to treat the secondary effluent from a wastewater treatment plant in Xuzhou City. When the influent COD and turbidi- ty were 60 mg/L and 15 NTU, the corresponding effluent values were 30 mg/L and 2 NTU, meeting the design standard. The practice showed that the combined process had advantages of high coagulation efficiency, fine filtration effect, good effluent quality and strong adaptability, and it had some promotion value.
