UV/TiO_2/H_2O_2法对高浓度有机废水降解的应用研究

用UV TiO2 H2 O2 法对高浓度有机废水降解的实验表明 ,当TiO2 、H2 O2 的投加量分别为 2 0g与 1% ,反应时间为3h时 ,CODCr、Oil、Ar OH、NH3 N、S2 - 的平均去除率分别达到 73 %、83 %、86%、5 0 %、10 0 %。此处理工艺具有除臭、除色、快速高效、不产生污泥等优势。实验过程探索了TiO2 、H2 O2 的用量对各污染物降解率的影响 ,并设计了有实用意义的反应器

APPLIED STUDY OF THE DEGRADATION OF ORGANIC SEWAGE OF HIGH CONCENTRATION USING UV/TiO2/H2O2

The industrial organic sewage of high concentration was degraded by using the process of UV/TiO_2/H_2O_2,the average degradation rate of COD_ Cr,Oil,Ar-OH,NH_3-N and S 2- was 73%,83%,86%,50%,and 100% respectively,while adding TiO_2 20 g and H_2O_2 1% to this reactor.Its advantages were deodorization,decolorization,high and fast effective,no slime occured etc..It was investigated that the effects of the quantity of TiO_2 and H_2O_2 on the degradation rate of each pollutant,and a practical reactor was also designed.
