印染废水回用的连续微滤/反渗透技术

Continuous microfiltration/reverse osmosis technique for reuse of dyeing effluents

采用连续微滤(CMF)+反渗透(RO)技术对印染废水进行深度处理,研究CMF+RO集成工艺的处理效果。试验结果表明,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98%以上,RO出水水质优于自来水,各项水质指标均满足印染工艺回用水的要求。

Advanced treatment of dyeing wastewater is carried out with continuous micro filtration （CMF）and reverse osmosis （RO） combined process, and its effect is studied. The results show that the system of the combined process with CMF and RO works smoothly,and can effectively remove over 98% of the total CODCr, chromaticity, turbidity and conductivity. The wa- ter quality of RO effluent is superior to that of tap water. The main water quality indexes of the treated water can meet the de- mands of dyeing and printing process.
