微污染水源水中毒害有机物的控制措施及最新研究进展

目前中国饮用水有机物污染日益加重,其危害性也逐渐被人们所重视,随着科学发展,许多水处理方法不断开发。文中阐述了控制微污染水源水中毒害有机物的主要措施：强化混凝、吸附、臭氧/生物活性炭联用、化学氧化、离子交换、膜技术等,不同的处理工艺对不同有机物的去除能力不同,某些工艺本身亦存在着问题,如膜技术存在着膜污染问题等,目前的研究是将多个工艺组合起来,形成联合工艺,从而达到多种污染物同时去除的目的,获得较好的水质。

Development of Treating Toxic Organic Compounds in Micro -polluted Water Resource

At present, the organic pollution of drinking water becomes more serious in our country. More attention has been paid to its harmfulness. With the development of science, many water treatment methods are developed continuously. The main control measures for organic matter in micro -polluted water resource were discussed：enhanced coagulation, adsorption, ozone/ biological activated carbon process, chemical oxidation, ion exchange, and membrane technology, and so on. Different treatment technology has different removal rate for different organic matters. Some technology has problems in itself. For example, membrane technology has problem of membrane fouling, and so on. The research, nowadays, is to combine multiple processes to form combined technology, to achieve the goal of several pollutants removal, meanwhile, get good water quality.
