( s ) ozonation did n ' t have great influence on thmfp but the effects of biological activated carbon were obvious , the removing rate could reach 10 % , and 30 % to remove haas ( 5 )臭氧化对三卤甲烷生成势的影响不大,但是生物活性炭有着较明显的效果,去除率可以达到10 ,对卤乙酸的去除率可以达到30 。
Advanced water purification uses ozone treatment and bio - activated carbon treatment during the conventional sedimentation and rapid filtration processes . this treatment breaks down trihalomethane , and substances causing a moldy odor 先进的水净化设备在传统沉淀和快速的过滤过程中,使用氧气处理和活性炭处理,这一处理除去了三卤甲烷等引起发霉味道的物质。
This paper expounds the developing situation of halogen disinfecting by - product in drinking water ( thms and haas ) , analyzes on the harms of the by - product to human health , introduces the effective paths of eliminating the by - product , and looks forward to the research directions in the future 论述了饮用水卤代消毒副产物(三卤甲烷和卤乙酸)的研究现状,分析了其对人类健康的危害,介绍了去除副产物的各种有效途径,并展望了今后的研究方向。
Check residual chlorine with residual chlorine reagent and claim that the tap water contains chlorine , which would act with pollutant and generate trihalogenmethane and the product is a substance of carcinogen . filter can effectively remove trihalogenmethane from drinking water and helps to ensure health 以馀氯试剂检测水样的馀氯量,声称自来水含有氯,与污染物反应生成三卤甲烷为致癌物质滤水器可有效去除饮水中三卤甲烷,确保人体健康。
The transferabilities of disinfectant outgrowths . the transformations admixed with chloroamine disinfectant water and chlorizating disinfectant water in conveying tubes have been particular analyzed . mostly work and conclusions as follows : ( 一 ) using simulative test and crosswise test , changing some parameters such as the sequence and proportion of chloroamine affiliated C )采用氯胺消毒方式时,预加氯成为总三卤甲烷、卤乙酸生成量的决定因素,取消预加氯将大幅度减少氯消毒副产物的生成,而对于滤后水消毒剂量(主要为一氯胺)的控制影响不大。
The quality of tap water supplied by twd meets completely with drinking water regulation , safe and healthy . the concentration of total trihalogenmethanes is only 1 10 of the standard of water quality of advanced countries like europe , usa and japan . concentrations of harmful substance like heavy metal and pesticides are so low that instrument could not detect them out 处供应的自来水水质完全符合饮用水水质标准,安全卫生,三卤甲烷含量仅为欧美日等先进国家水质标准的1 10 ,重金属农药等有害物质含量更是低到仪器无法检测出来。
