摘要
通过砂滤池出水后接UV/H2O2高级氧化中试试验设备并投加特征污染物,考察了UV,UV+颗粒活性炭(GAC),UV/H2O2,UV/H2O2+GAC工艺对阿特拉津、嗅味物质及消毒副产物生成量的去除效果,发现UV/H2O2+GAC工艺对土臭素去除效果最好,去除率高达95%以上;对MIB和阿特拉津的去除效果比较接近,去除率在70%以上;UV/H2O2能有效去除消毒副产物前体物、减少消毒副产物的生成。
To study the efficiency of UV, UV＋GAC, UV/H2O2, UV/H2O2＋GAC water treatment on removing atrazine, 2-Methylisoborneol （2-MIB）, geosmine and disinfection by-products production, a UV/H2O2 pilot test equipment is connected to the outlet of sand filter and target pollutants were injected into the filtered water. The results show that UV/H2O2 ＋ GAC advanced oxidation technology has the best effect on removing geosmine, the removal rate of which reaches over 95 %. The removal effects of 2-MIB and atrazine is approximate, the removal rates of which are about 70 % by UV/H2O2＋GAC treatment. Less disinfection by-products is formed in UV,/H2O2 water treatment.
