摘　　要：采用TiO2光催化氧化法处理敌敌畏生产废水,试验结果表明,光催化5h后,对废水中污染物的去除率不高,废水的COD去除率为24.1%,无机磷生成率为36.7%,TOC的去除率为18.0%,但是BOD5与COD的比值则由0.18提高到0.68,废水可生化性得到大大改善,为后续生化处理创造了有利条件。TiO2 photocatalytic oxidation process was used to treat wastewater from DDVP production, the results of the test showed that, 5-hour photocatalytic oxidation could not remove pollutants from the wastewater effectively, the removal rates of COD and TOC were 24.1% and 18.0% respectively, the generation rate of inorganic phosphorus was 36.7%, however, when the ratio of BOD5 to COD increased from 0.18 to 0.68, the biodegradability of the wastewater was greatly improved, which was beneficial to the following biochemical treatment.
