臭氧-活性炭组合工艺在污水再生中的应用

Application of Ozone-activated Carbon Technology in Wastewater Reclamation

臭氧-活性炭组合工艺应用于各类污水的再生中,如城市污水,工业废水,养殖废水和食品废水等.各种数据表明,该组合工艺对COD,TOC,UV254,氨氮,色度等指标有很好的去除效果.其中对色度的去除最明显.根据污水处理过程中遇到的各种问题,如处理费用高,出水细菌超标,NO-3-N去除效果不理想等,臭氧-活性炭组合工艺常和其他工艺技术联用,如混凝沉淀,气浮等预处理技术、膜分离技术、反硝化生物滤池、高级氧化技术等.臭氧-活性炭组合工艺是一种新型高效的水处理方法,具有较大的应用和推广价值.

Ozone-activated carbon technology is used in the reclamation of wastewaters,uch as urban sewagei,ndustrial wastewaterb,reeding wastewaterf,ood wastewater and so on.All data show that the technology is very effective at removing COD,TOC,UV254a,mmonia nitrogen and chromaticitye,specially chromaticity.In view of various problems arising in the sewage processing procedures,uch as high processing fee,excessive amount of bacteria in treated water,unsatisfactory removing effect of NO-3-Ne,tc,ozone-activated carbon technology is often combined with other technologiess,uch as coagulation and floating,membrane separation technologyd,enitrifying bio-filter and advanced oxidation technologye,tc.Ozone-activated carbon technology is a new type of advanced water treatment method,worthwhile to be widely used and spread.
