摘要
介绍了我国水资源环境的现状,水体污染的来源及控制技术,重点论述了来自农田和畜禽养殖粪便的富营养化污染和控制技术。我国水体中总磷、总氮的43%和53%来自于农田和畜禽粪便,在经济发达的地区尤以畜禽粪便的贡献突出,是水体富营养化的主要污染源。因此污染源头的治理是控制水体富营养化的根本出路和手段。系统的论述了国外成熟的源头控制与循环利用技术以及我国的源头控制与循环利用技术的现状和发展趋势。
The current situation of water environment in China, the mason of water pollution and the controlling technology for it are presented, focusing on water eutrophic pollution from agricultural production and livestock breeding. 43% of total nitrogen and 53 % of total phosphorus in water come from farmland and livestock, and it is even more serious from livestock in developed areas in China. Controlling the pollution resource is the basic method to control the eutrophicated pollution in water body. The related technology available and developmental trends both in China and abroad are summarized.
