摘　　要：采用酸解-Fenton氧化对甲胺磷废水进行预处理试验，研究结果表明：在酸解反应过程中，在pH为2，反应温度100℃的条件下，TOC和硫化物的去除率分别达18．33％和90．7％；在Fenton氧化反应过程中，在pH为4，n（H2O2）：n（Fe^2＋）=30：1，H2O2投加体积分数为3．0％的条件下，TOC去除率达24.3％；投加20％Ca（OH）2乳液，pH为11-12时，可将Fenton氧化后的废水中绝大部分的无机磷除去。The pretreatment of methamidophos pesticide wastewater has been carried through by acidification- Fenton oxidation process. The results show that during the acidification reaction, and under the following conditions： the pH is 2, and reaction temperature 100℃, the removal rates of TOC and sulfide can reach 18.33% and 90.7% respectively. In the process of Fenton oxidation reaction, and when pH is 4, n （H2O2）：n （Fe^2＋）is 30：1, and a dosage of 3.0% of H2OE, the removal rate of TOC can reach 24.3%. When 20% of Ca（OH）2 emulsion is added, and the pH is between 11 to 12, most of the inorganic phosphorus in the Fenton oxidized wastewater can be removed.
