摘要
UV/H2O2降解水中的有机污染物质,将其矿化为CO2和H2O,或降解为易于生物降解的小分子有机物,降解效果受HCO3-等离子的影响;UV/H2O2系统中H2O2存在一临界投量,由于底物种类和浓度的不同而差异较大;UV/H2O2系统去除饮用水中的有机微污染物,与GAC单元结合,可以极大地缩短和降低反应器中的HRT和H2O2的投量,处理效果与O3/GAC相近,使UV/H2O2高级氧化技术得以经济地应用于工程实践.
The organic substance can be completely oxidized into CO2 and H2O, or decomposed into small molecules, and the removal efficiency is affected by anion, e.g. HCO3-. There is critical concentration in oxidizing process, and along with the different substrates, the dosage of H2O2 is also different. By combining with GAC unit, the reaction time can be shortened and the dosage can be cut down. Meanwhile, the removal efficiency of organic substance is closed to O2/GAC technique, which can make this technique be utilized economically into practical engineering.
