Abstract: Aiming at the limitation of single method and single function of urban sewage treatment,the combined technology of advanced oxidation,efficient adsorption and biofilm process has been used for treating NH₃-N,PO₄^3- and COD in urban sewage,in order to achieve the purpose of simultaneous removal. Using Fenton reagent as advanced oxidant,and Zeolite,steel slag and activated carbon as composite adsorption materials,the bio-film formation of ad-sorptive materials by activated sludge is implemented. The contrast test research is accomplished through adsorption column,Fenton-adsorption column,biofilm-adsorption column and Fenton-biofilm-adsorption column in order to determine the purification effect and reveal synergistic purification mechanism.

Key words: urban sewage, advanced treatment, nitrogen removal, phosphorus removal, organics removal

摘要： 针对城市污水深度处理单一方法、单一功能的局限性，采用高级氧化、高效吸附与生物膜法联用来深度处理城市污水中NH₃-N、PO₄^3-和COD，以达到同步去除的目的。以Fenton试剂作为高级氧化剂，沸石、钢渣和活性炭作为复合吸附材料，活性污泥对吸附材料进行挂膜，通过单独吸附柱、Fenton-吸附柱、生物膜-吸附柱和Fenton-生物膜-吸附柱进行对比试验研究，以确定净化效果，揭示协同净化机理。
