摘　　要：采用以浸没式超滤和反渗透为核心的组合工艺对煤气化废水进行了深度处理,并对不同工艺组合中浸没式超滤和反渗透的运行工况进行了比较,得出了煤气化废水深度处理的最佳工艺,该工艺运行下的浸没式超滤和反渗透最佳运行通量分别为30.0 L/(m2.h)和16.8 L/(m2.h).Through the advanced treatment of the coal-gasification wastewater by using combined membrane processes of immersed UF and RO, and the comparison of the operation conditions of its various combined processes, the authors of this paper find out the optimized process for the advanced treatment of the research object, the optimized running fluxes under the immersed UF and RO of which are 30.0 L/（m^2.h） and 16.8 L/（m^2.h） respectively.
