In order to reuse the wastewater and reduce the production cost, the treatment and reuse of printing and dyeing wastewater by using the technology of continuous membrane filter(CMF)-active carbon has been studied. The reasults show that when the wastewater is treated by using CMF or using active carbon respectively, the effluent cannot meet the requirement of printing and dyeing technology; but when the wastewater is treated by using CMF and using active carbon in combination, the effluent efficiency of CMF-active carbon is better than active carbon-CMF. The Fe, Mn removal rates in effluent is up to 100%. Its total hardness is 0.325 mg/L, the chromaticity is 4, turbidity is 0.2 NTU, its pH value is 7.0. The engineering investment of CMF-active carbon treatment and running cost are analysed. This technolgy applied to printing and dyeing fields is pretty valuable.
