摘　　要：以再生水循环利用过程中可能富集的污染物为对象,通过对比研究"臭氧-生物活性炭"(O3-BAC)与"强化混凝-沉淀-过滤"这两种工艺对水中污染物的去除特性,得到两种工艺对水中污染物色度、氨氮和总氮、总磷等的去除结果,以及臭氧氧化出水相对分子质量和有机物分子结构的变化情况。研究结果表明O3-BAC工艺对有机物、色度、氮、磷等污染物具有更好的处理效果,是适合于再生水循环利用系统水质保障的污水深度处理工艺。With the pollutants that may be enriched during the process of reclaimed water recycling as the research object, the pollutants removal performances of ozone-biological activated carbon（O3-BAC） process and enhanced coagulation-sedimentation-filtration process were compared and studied, and then, the removal rates of colority, ammonia nitrogen, total nitrogen and total phosphorus by the said two processes were detected, further more, the variation of the relative molecular mass and the molecular structure of the pollutants in the effluent water after the ozone oxidation were also inspected. The results showed that, O3-BAC process had a good effect on organic matters, colority, nitrogen, phosphorus and some other pollutants removal, which was a suitable process for wastewater advanced treatment and could ensure water quality for reclaimed water recycling system.
