污水除磷技术的研究进展

水体中氮磷的累积是引起水体富营养化的主要原因之一。富营养化污染是目前世界各国面临的重大环境问题。造成湖泊富营养化的限制性物质主要是磷。因此,除磷技术的研究和应用就显得十分重要。除磷技术效果比较好、应用比较多的是生物除磷技术和化学除磷技术,两种技术各有优缺点,除磷技术的发展方向是生物除磷和化学除磷的联合使用。

Development of Research on Phosphorus Removal form Wastewater

The accumulation of nitrogen and phosphorus compounds is one of the main causes for eutrophication in water bodies. The pollution of eutrophication is an important environmental problem in the world. The restrictive factor which resulting in eutrophication is phosphorus. Thus it is important to study and apply the technology of phosphorus removal. The biological phosphorus removal and chemical phosphorus removal have their shortcomings respectively. The developmental direction of phosphorus removal is simultaneous application of biological and chemical phosphorus removal.
