This paper was prepared by liquid phase deposition of quartz sand load nanometer titanium dioxide film, in which quartz sand as the carrier, and to Fe3+,Zn2+ as doping on the membrane was modified. The initial value of pH is 6.7,in this condition, select the heating temperature, the doping ratio of Fe3+andZn2+ to design the orthogonal experiment. CODCr removal and pH value as the evaluate index, to deal with the real tannery wastewater, discussed when Fe3+,Zn2+ co-doping, the best doping ratio of them, the best technical conditions such as heat treatment temperature; and their affect on CODCr removal rate and pH value.Under the optimum conditions, confirmed by further study that Fe3+ doped titanium dioxide modified membrane absorption band red shifts, the utilization of solar is increased, the tannery wastewater which was treated by modified membrane, its biodegradability is greatly increased.
