中文摘要 |
在中试集成系统水平上对比研究了常规工艺、预臭氧化工艺、粒状活性炭吸附工艺、臭氧-生物活性炭工艺对受污染源水中的有机物及消毒副产物前体的去除效果。结果表明,前2种工艺对有机物的去除效能大致在50%~60%,后2者则能达到75%~90%。与前2者相比,后2者是更有效地去除受污染原水中有机物的方法。建议采用Ⅱ类及更优水体为水源的水厂考虑使用常规处理或季节性水质变化时采用预氧化工艺;而对于那些以Ⅲ类或更差水体为主水源的水厂则应考虑增设GAC或BAC设备,以满足饮用水水质新标准要求。 |
英文摘要 |
The traditional technique, preozonation technique, granular activated carbon adsorption technique and ozone-biological activated carbon technique were compared on its removal efficiency of organic matter and the THMs formation potential (THMFP) as well. It was found that, as compared with the former two techniques, the last two were more effective in organic matter removal, and the efficiency reached 75%~92%, while the former only at 50%~60%. The waterworks that adopted the Grade II source raw water were suggested to use the conventional techniques and seasonal preozonation techniques, while the others were suggested to alternatively select GAC or BAC technique to meet the request of new water quality criterion. |
