| 摘 要： | 对光稳定、生物难降解的甲拌磷农药废水经ＴｉＯ２或负栽型ＴｉＯ２光催化降解方法处理，化学耗氧量达到排放标准。研究了ＰＨ值、阴离子种类对降解过程的影响，ＰＨ〈２或ＰＨ〉８时，降解率高于５０％。催化剂稳定性好；当ＣＯ３＾２－和ＳＯ３＾２－离子质量浓度约为６．０ｍｇ／Ｌ时降解率下降２０％。

| Abstract: | The photocatalytic degradation of phorate in wastewater, which is one of the typical refratory biodegradable and photostable orgaophosphorus pesticides,was studied using TiO 2 partical and loaded TiO 2 on SiO 2 as photocatalysts respectively The results showed that the value of COD was below 200mg/L after the treatment process The effect of pH,anions such as CO 3 2- ,SO 3 2- ,PO 4 2- ,and SO 4 2- on the effciency of the photocatalytic degradation was discussed |

| Keywords: | phorate loaded TiO 2 on SiO 2 orgaophosphorus pesticide photocatalytic degradation refratory biodegradability |
