采用Fenton氧化法处理有机硅工业废水。通过正交试验和单因素试验，考察了反应时间、 n(H2O2)/n(Fe2+)、温度、 pH值和H2O2投加量等因素对废水CODCr去除率的影响。结果表明， Fenton氧化法的影响因素主次为： H2O2投加量、 pH值、温度、 n(H2O2)/n(Fe2+)、反应时间；在pH值为3、 n(H2O2)/n(Fe2+)值为6、反应时间为60 min、温度为35℃的最佳条件下，对于CODCr的质量浓度为5440 mg/L的有机硅废水，在100 mL的水样中投加14 mL H2O2(30%)，可使CODCr的去除率达到90.92%。

Fenton oxidation process was used to treat organic silicon industrial wastewater. Through the or-thogonal test and single factor test, the influence of reaction time, n (H2O2) : n (Fe2+), temperature, pH value, H2O2 dosage and some other factors on CODCr removal were investigated. The test results showed that, the effect of the influencing factors of Fenton oxidation process followed the decreasing order of H2O2 dosage, pH value, temperature, ratio of n(H2O2) :n(Fe2+), and reaction time. Under the optimal condition that the mass concentra-tion of CODCr was 5 440 mg/L, the ratio of n(H2O2) :n(Fe2+) was 6: 1, the reaction time was 60 min, the tem-perature was 35℃, dosing 14 mL of H2O2(30%) into the organic silicon wastewater sample with mass concentra-tion of CODCr of 5 440 mg/L, the removal rate of CODCr could reach 90.92%.
