摘　　要：针对水中污染物的特性,从污染物极性角度考虑,将极性无机吸附剂——多孔性软陶粒与活性炭组成复合滤料,提出了臭氧/无机+有机吸附剂组合强化去除水中污染物的作用机制,开发了臭氧/复合吸附组合工艺,将臭氧氧化、滤料的物理、化学吸附技术有机结合,充分发挥了三者协同作用,对水中污染物具有去除效率高、效果稳定等特点.臭氧/复合吸附组合工艺在最佳工艺条件下,对经常规处理后的济南狼猫山水库水中的浊度、CODMn、UV254、NH3-N和NO2-1-N的去除率分别达到92.2%、87.7%、86.3%、88.6%和92.3%.According to the polarity of water pollutants,ceramisite and GAC are composed for a new composite filtration.Combined with ozone,the O3/composite adsorption process is used for advanced treatment of drinking water.The process fits ozone oxidation and composite adsorption has the advantage of high removal efficiency and stability in characteristics.Under the optimal condition for treating reservoir water,the removal rates of turbidity,CODMn,UV254,NH3-N and NO2-1-N are proved to be 92.2%,87.7%,86.3%,88.6% and 92.3% respectively.
