摘    要本次的课题主要是研究不同催化条件下对Fenton法处理工业废水的影响，着重分析杭州久福实业有限公司的电镀废水，分析其特点及Fenton法处理废水过程中最佳处理方案。

首先将粉煤灰进行改性，分别在两种废水的处理中比较其COD的降低率，得出的结论是酸改性>未改性>碱改性，从而得出酸改性可以提高粉煤灰的催化性能。89463

同时采用控制变量法对杭州临江前进齿轮和杭州久福实业的废水进行研究，得出前者废水在改性粉煤灰的类Fenton实验的最佳条件：反应时间为60min，粉煤灰投加量为30g/L,过氧化氢投加量为9。4mmol/L,后者的最佳条件为反应时间为45min，粉煤灰投加量为35g/L,过氧化氢投加量为18。3mmol/L。COD的去除率最高在72%左右。

此次实验能为类Fenton在实际工程的运用提供一些理论依据，对处理工业废水有一定的意义。

Abstract The main task of this project is to study the effect of different catalytic conditions on the treatment of industrial wastewater by Fenton method, and to analyze the electroplating wastewater of Hangzhou Jiufu Industrial Co。, Ltd。, analyze its characteristics and the best treatment scheme of Fenton process in wastewater treatment。

First, the fly ash was modified, and the reduction rate of COD was compared in the treatment of the two wastes。 The conclusion was that the acid was modified> not modified> alkali modified to obtain acid Catalytic Performance of Coal Ash。

Then the control variables were used to study the waste water of the two enterprises。 The optimum conditions of the Fenton experiment were as follows: the reaction time was 60min, the dosage of fly ash was 30g / L, The dosage of hydrogen peroxide is 9。4mmol / L, the best condition is 45min, the dosage of fly ash is 35g / L, and the dosage of hydrogen peroxide is 18。3mmol / L。 COD removal rate of about 72%。

The experiment can provide some theoretical basis for the application of Fenton in practical engineering, which is of great significance to the treatment of industrial wastewater。
