Several processes by integrating with membrane systems such as stripping-membrane-distillation， multiple stage membrane concentration， pervaporation- distillation， etc. were designed and developed to treat chemical wastewater containing valuable components（e.g.， polyol， polybasic acid， ester， inorganic salt）. The combination of the integrated processes with the chemical production processes can effectively reduce COD in the treated wastewater and realize the recovery of the valuable components in chemical wastewater， and consequently decrease the cost of wastewater treatment. Therefore， application of these processes could be helpful for the sustainable development of chemical industry.
