With the aggravation of organic pollution of the drinking water source and the improvement of the water-quality standards, the conventional treatment craft of drinking water used in most of water plants in China can't remove the organic pollutant effectively to satisfy people's demand in the water quality. Consequently, permanganate preoxidation technic and mineral materials are combined with coagulation to removing the organic pollutant of drinking water further, so that to solve the increasing contradiction between the aggravation of organic pollution of the drinking water source and the striction of the water-quality standards.

随着饮用水源有机污染的日益加重以及饮用水水质标准的不断提高，我国大多数水厂所采用的传统处理工艺不能有效地去除有机污染物，从而对饮用水水质产生一定的影响，因此，引入高锰酸钾预氧化技术和矿物吸附材料，从而强化去除饮用水中的有机污染物，以解决水源有机污染日益严重与饮用水水质标准日趋严格之间的矛盾。

The samples'concentration level is ng/L, meanwhile, which doesn't go beyond the national standard "Environmental quantity standards for surface water-GB 3838—2002"and "Drinking water quality criteria standard GB5746-85". The study shows that the water purification palnts in The Three Gorges Reservoir Area especially those raw water from Yangtze River and Jialingjia River is safe enough for drinking and its level is low. After having tested and analyzed the raw water samples of 6 water purification plants in Three Gorges Reservoir Area, I have found several variety of PAHs and PAEs. Of which, naphthalene, fluoranthene and DEHP are priority pollutants firstly listed by SEPA..

按照《地面水环境质量标准GB 3838—2002》和《生活饮用水水质标准GB5746-85》对有机氯农药的规定，上述6 个水厂均未超标，表明三峡库区城市给水厂特别是以长江、嘉陵江为水源的水厂，其有机氯农药污染较轻，饮用水水质安全。6 个给水厂的原水均检出含有多种PAHs 和PAEs，其中包括有我国国家环境保护总局首批公布的水中优先检测污染物萘、荧蒽、DEHP。

Therefore, systematically research on protection of headwater area of reservoir hasprofound and significant meanings.

在我国南方地区，伴随着社会经济的快速发展和城市化进程的迅速推进，许多河流的中下游河段由于点源和面源污染加剧而丧失了饮用水功能，河源区段的水库已经成为目前最重要的城市集中式饮用水供水水源。
