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.
