摘　　要：采用正交试验法对负载型纳米二氧化钛光催化剂降解工业污水中有机污染物的过程进行了分析与研究 ,探讨了有关因素对工业污水中有机物的降解率的影响 ,并确定了最佳的降解条件。通过实验认为 。It was studied that the organic pollutant in the industrial wastewater was degraded with the photocatalyst of conted nanometer sized titanium dioxide by the method of orthogonal test from the angle of photocatalytic chemistry in this paper. The factors concerned to influence the rate of degrading the organic pollutant in the industrial wastewater were discussed and the optimum conditions to degrade organic polutant were determined. It was thought that the mass percentage of nanometer sized titanium dioxide in the photocatalyst was main factor to influence the rate according to the experiment.
