摘　　要：采用活性炭悬浮式光化学反应仪进行了光催化臭氧氧化不同分子量的聚乙二醇(200-20000)水溶液的研究,考察了臭氧氧化、UV、活性炭吸附和活性炭催化臭氧氧化等不同条件下COD去除率效率,证明活性炭不仅具有对有机物的吸附作用而且同时也具有对臭氧氧化的催化作用。聚乙二醇在活性炭上的吸附特性对其降解具有重要的作用,但是在此系统中不能够完全降解聚乙二醇。The catalytic ozonation of polyethylene glycols (PEG) solution with different molecular weight (MW200-20000) in a fluidised activated carbon reactor was investigated. Experiments were conducted to examine the effect of various operating variables on COD removal efficiency including ozonation, UV, activated carbon adsorption and catalytic ozonation combined with activated carbon adsorption. It was observed that activated carbon acts not only as an adsorbent, but also as a good catalyst in promoting ozonation. Adsorption properties of activated carbon did important roles in the catalytic ozonation, but total degradation of PEG by carbon dioxide was difficult.
