| 中文摘要 |
| 采用我国城市供水行业2000年技术进步发展规划水质目标与Ames试验评价现有水处理工艺与模拟水处理工艺的净化效果,为受污染水源的净水工艺选择提供参考依据。结果表明:①现有水厂传统处理(T)工艺出水有嗅味、氨氮、矿物油、亚硝酸盐氮、酚类、多环芳烃类等多项水质超标,与原水相比,致突变活性进一步增强;②在传统处理之前,增加生物预处理(BT)工艺或之后增加活性炭吸附处理(TC)工艺,均能有效改善水质,降低致突变活性;③只有生物处理、传统处理、活性炭吸附、臭氧氧化等的组合工艺(BTC、OBTC)能全面改善和提高饮用水水质,达到2000年规划水质目标要求,并使水的致突变活性转为阴性反应。 |
| 英文摘要 |
| Based on the drinking water quality goals proposed by The developing plan of technology progress for municipal and town water supply in 2000and Ames test,a practical and a pilot drinking water treatment processes were assessed,which will be benifit to treatment process selection for polluted source water.The follows can be concluded:①Several water quality parameter such as ordor,ammonia,mineral oil,phenol,PAH,etc,cann't meet the criterial in the practical conventional process effluent,compared to source water,mutaginicity of effluent rised.②That bio-treatment unit was put before conventional process,as well as GAC unit was put after conventional process can improve effluent quality and reduce mutaginicity.③Only intergation of bio-treatment unit,conventional treatment unit,ozone oxidation and GAC absorption can improved drinking water quality in all aspects,meet the goals of 2000 year and make Ames test result to negative. |
