摘　　要：进行了UV/H2O2/GAC系统用于饮用水深度处理的试验研究,结果表明,UV/H2O2/GAC对UV254和TOC均有良好的去除效果,当H2O2投量为3.0 mg/L,UV/H2O2反应器停留时间为20 min时,系统的COD和UV254去除率为44.6%和72.8%.UV/H2O2主要作用在于改善了GAC对有机物的吸附,产生了羟基自由基,从而提高了去除效果.In this paper,the UV/H2O2/GAC system was studied in drinking water advanced treatment process. The experimental results indicated that the removal efficiency of UV254, TOC by UV/H2O2/GAC were good. The better conditions of UV/H2O2/GAC system were： the H2O2 dosage was 3.0 mg/L and the UV radiation time was 20 minutes, the removal efficiency of COD and UV254 is 44.6% and 72.8% respectively. The main function of UV/ H2O2/GAC is that the absorption improvement of GAC on was chiefly due to the· OH generated by UV/H2O2. The removal efficiency of organic substances will be increased.
