The invention relates to a cathode and anode built-in ceramic micro-filtration membrane reactor suitable for removing pollutant in source water. According to the invention, titanium mesh is taken as cathode, an Sb element-doped titanium-based SnO2 coating A electrode or a mixed coating B electrode with TiO2 and SnO2 loaded on the basis of the A electrode serves as an anode, and the cathode faces to two sheets of anodes and is placed into a micro-filtration membrane module. The reactor applies extra electric field by constant voltage DC source, and operates under a continuous flow mode, the particles and colloid in source water can be filtered by the ceramic micro-filtration membrane with the aperture of 0.1-0.4 [mu]m, under electrocatalysis effect, a lot of substances with strong oxidizability is generated in water, and removal of the organic pollutants which are difficultly degraded is realized. doping of Sb can obviously increase the conductivity of SnO2, the coating of the electrode has physical sorption e
