摘　　要：采用"一体臭氧曝气生物滤池+曝气生物滤池(BAF)"组合工艺,对纺织印染废水进行预处理,联合后续膜分离工艺以实现中水回用,处理水量为5 000 m3/d。设计运行条件下,臭氧曝气生物滤池最佳臭氧投加量为20-30mg/L,预处理系统出水COD<40 mg/L、BOD<10 mg/L、SS<10 mg/L、色度<4倍;反渗透产水可作为染整工艺用水,膜滤浓缩液可达标排放。工程实践证明,该联合工艺可实现对纺织印染废水的深度处理与高质回用,并解决了膜滤浓缩液的处理难题,具有推广应用价值。For the purpose of water reuse with a capacity of 5 000 m3/d, a combined process of integrated ozonation biological aerated filter and biological aerated filter（BAF） has been used for the pretreatment of textile and dyeing wastewater. Then,membrane filtration has been used for achieving water reuse. Under designed operating conditions,the optimal ozone dosage for integrated ozonation biological aerated filter is 20-30 mg/L,pretreatment effluent COD〈40 mg/L, BOD〈10 mg/L, SS〈10 mg/L, and chroma〈4 times. The water produced by RO system could be reused in dyeing process, and membrane filtration concentrate could be discharged under local regulations. It has been proved by practical application that the combined process could guarantee stable advanced treatment and reelaimation of textile and dyeing wastewater with high quality,and solve the problem of membrane filtration concentrate treatment, showing its broad popularization and application value.
