摘　　要：以某工业园区印染废水处理厂二级生化出水为处理对象,采用预氧化+膜生物反应器(MBR)+反渗透(RO)的组合工艺对其进行深度处理,以达到企业回用水要求。实验结果表明,在进水COD为105~120 mg/L,色度为50倍的条件下,当氧化剂用量为3 mg/L,MBR水力停留时间为3~3.5 h时,组合工艺的出水COD≤5 mg/L,色度≤5倍,电导率≤20μS/cm,出水水质满足企业回用水要求,RO浓水COD≤120 mg/L,色度≤50倍,达到排放标准。Taking the secondary biological treatment effluent of a dyeing wastewater treatment plant in an industrial zone as the treatment object,the combined process,pre-oxidation-membrane bioreactor（MBR）-reverse osmosis,has been used for its advanced treatment,in order to meet the requirements for the industrial reuse water.Experimental results show that under the conditions below：the influent COD is 105-120 mg/L,chroma 50 times,the dosage of oxidant 3 mg/L,and MBR hydraulic residence time 3-3.5 h,the effluent COD of the combined process is ≤5 mg/L,chroma ≤5 times,and conductivity ≤20 μS/cm,the effluent water quality meets the requirements for the industrial water reuse.RO concentrated water COD is ≤120 mg/L and chroma ≤50 times,achieving the discharge standard.
