采用连续微滤(CMF)+反渗透(RO)处理技术对印染废水进行深度处理,研究了CMF+RO集成工艺的处理效果。实验结果表明:CMF+RO处理系统运行稳定,对CODcr、色度、浊度、电导率的去除率均达到98%以上,RO产水的水质优于自来水,各项水质指标均满足印染工艺回用的要求。
Dyeing waste water was pretreated by CMF (continuous microfiltration) and RO (reverse osmosis) combined process, and the effect of this treatment was analyzed. Results showed that CMF and RO system was operated steadily and economically. It can effectively remove total CODcr, chromaticity, turbidity and conductivity by over 98%. The water quality of RO effluent is superior to that of tap water, and each water quality index meets the requirement of dyeing technique.
