摘要
由于各种污染物的排放,我国饮用水水源水质日益恶化,常规水厂的工艺已显得力不从心,作者对微污染水源水的处理技术作了简要介绍。重点分析了作为预处理技术的曝气生物滤池技术和作为后续处理的膜分离技术(特别是超滤技术)。在分别对这两项技术作了介绍的基础上,提出了曝气生物滤池(BAF)+常规工艺+超滤(UF)的净水工艺,指出该工艺是提高饮用水水质的最佳工艺。同时,用有机物分子质量的观点对此工艺进行了深入分析。
For the discharge of all kindsof pollutants,the quality of the source water of drinking water in our country isgetting worse day by day.And thismakesthe normal processused in most water plantsunable to do their jobswell asusual.So,the paper briefly introducesthe technologiesto cope with the micro - polluted source water.It givesemphasison two technologies,biological aerated filter( BAF )and the membrane separation techno - logy(especially the UF).Based on the analysisof these two technologies,the paper posesa new water purificati - on technology:BAF+normal process+UF.It indicatesthat thisisthe best way to improve the quality of the drinking water.Meanwhile,thisnew technology isfurther analyzed in term of organism molecular weight.
