【摘要】 近年来饮用水水源污染加重,及国家对饮用水标准要求越来越高,常规水处理工艺已经不能满足人们生活的需求,新的水处理工艺的开发及对传统工艺的改良和强化成为研究的重点。给水水源中存在持久性有机物、内分泌干扰物等微量有机污染物,且采用传统的加氯消毒技术会产生消毒副产物,催化臭氧氧化-生物活性炭联用工艺以其特有的优势成为给水深度处理技术研究的热点。本文在新型三级催化臭氧氧化-生物活性炭技术研发的基础上,针对受污染水源水的深度处理进行了中试研究。中试为期9个月、水量规模为120m3/d,试验经历了夏天到冬天的水温、水质变化过程,考察了各种水质指标的去除效率以及影响工艺出水性能的因素。研究结果表明,出水中耗氧量、高锰酸盐指数、NH4-N、浊度、色度、Fe和Mn都能达到生活饮用水卫生标准。THMsFP减少18%。催化剂的投加能有效降低工艺出水中溴酸盐的含量,与不投加催化剂相比,溴酸盐的含量降低了77%。臭氧投加量对锰的去除率影响不大。水中溴酸盐的含量随着臭氧投加量的增加而增加,但催化剂的存在下出水溴酸盐含量达标。本研究对促进多级催化臭氧氧化-活性炭工艺的推广与指导性生产应用、保障饮用水安全有着重要意义。更多还原

【Abstract】 In recent years, with the pollution of drinking water sources aggravating and the requirements of national drinking water standards improving, the need of people’s lives can not be met by conventional water treatment processes, so the development of new water treatment processes and the improvement and strengthening of the conventional processes had been the focus of the research. Due to the presence of persistent organic pollutants, endocrine disruptors and other trace organic pollutants in drinking water sources and the conventional chlorine disinfection technology generating disinfection by-products, the catalytic ozonation-biological activated carbon combined process with its unique advantages became the hot pot of advanced water treatment research. This paper carried on a polit-scale research for the advanced treatment of polluted source water based on the research of novel three-grade catalytic ozonation-biological activated carbon technology. This polit-scale research lasted nine months with 120m3/d water scale and experienced water temperature and water quality change process from summer to winter. It also studied the removal efficiency of various water quality indicators as well as the factors that affect the process water performance. The research results showed that the oxygen consumption of effluent, permanganate index, NH4-N, turbidity, chroma, Fe and Mn can meet drinking water health standards. THMsFP was reduced by 18%. Catalyst dosing can effectively reduce the process of bromate in water, compared with not adding the catalyst, the content of bromate was reduced by 77%. The ozone dosage had little effect on the removal rate of manganese. With the increasing of ozone dosage, the content of bromate in water increased, but the content in effluent can meet the standards in the presence of catalyst. This study was of great significance to the promotion of the spread and guiding production application of multi-stage catalytic ozonation-activated carbon process and to the guarantee of drinking water safety.更多还原
