摘　　要：为探讨低温条件下臭氧-生物活性炭系统处理印染废水的挂膜启动方法,采用臭氧氧化、活性炭吸附、生物氧化、活性炭生物再生共同作用,对印染废水二级处理出水进行深度处理。实验结果表明:低温条件虽然延长了系统的挂膜启动时间,但不影响挂膜质量,22 d后挂膜启动完毕,浊度、色度、COD去除率分别为68.76%、73.2%、60%,出水水质良好且稳定。To discuss the treatment of dyeing wastewater by using ozone-biological activated carbon system under the condition of low temperature, ozone oxidation, active carbon adsorption, biological oxidation, and biological activated carbon regeneration interaction were used to treat secondary effluent of dyeing wastewater. Experimental results showed that although low temperature conditions prolonged start-up time of the system, did not affect the quality of membrane hanging. After 22 d, microbial biofilm was over. The removal rates of turbidity, colority and COD were 68.76% , 73.2% and 60% , the effluent quality was good and stable.
