摘 要

水资源的利用是当今社会日益严肃的话题，随着工业社会的发展，水污染问题同样在扩张，废水的处理变得十分必要。本课题着重研究电解废水的相关内容及研究。从其背景出发，然后设计实验装置及方法步骤。主要研究电解苯酚实验时最优电解效果的各实验条件的参数值。利用三维电极进行探究，采用活性炭作为电极。在实验室条件下模拟实际污水的有机成分，通过调节极板间电压及溶液PH值来计算苯酚的去除率及COD的去除率。同时研究电解苯酚这类有机物得到的产物，一般为小分子的有机物或者直接被氧化为二氧化碳和水。最后利用紫外光谱分析苯酚降解过程，最优实验条件下紫外吸收光谱分析结果分析，得到最终的实验结果。探究出电解苯酚去除率最大时的最优实验参数为：板间距10cm；槽电压15V；溶液PH为5。COD的去除率最高可以达到70%，而苯酚的去除率则可达到80%以上。

Waste water electrolysis device selection and experimental studies of electrode

Abstract

The use of water resources are becoming an increasingly serious issue in today's society, with the development of the industrial society, the water pollution problem in the expansion, same wastewater processing become very necessary.This topic focuses on related contents and electrolytic water research. Starting from the background, and then design the experiment device and steps.Exploring the electrolytic phenol experiment the optimum electrolytic effect of experimental parameters values.Using three-dimensional electrode experiments, the experimental study using activated carbon as electrode .Under laboratory conditions simulated wastewater organic composition, by adjusting the voltage between the plate and the solution PH value to calculate the removal rate of phenol and COD removal rate. Explore the product of electrolytic phenol and other organic matter to get at the same time, generally for small molecule organic matter or directly oxidized to carbon dioxide and water .Finally using ultraviolet spectrum analysis of phenol degradation process, the optimal experimental conditions of ultraviolet absorption spectrum analysis results analysis, the final experiment results are obtained. Explore the electrolytic removal rate of phenol maximum when the optimal experimental parameters for: plate spacing 10 cm; Cell voltage 15 v. Solution PH of 5. COD removal efficiency can reach 70%, while the removal rate of phenol could reach more than 80%.

Key words: water pollution；electrolytic；removal rate；three dimension electrode；spectral analysis
