污水处理与资源化利用

The Wastewater Treatment and Reuse

通过对我国目前水资源储量, 需水概况,指出我国水资源态势的严重性。我国水资源匮乏的主要因素是地面径流量日益减少,盲目超量开采地下水,用水浪费及水体严重污染。提出污水回用的重要性,必要性及可能性。 并针对目前我国水处理工作的艰巨性,提出今后对工业废水的处理必须遵循工业生产的循环经济原则,提高城市污水的无害化处理率;开发水处理新工艺从而降低水处理费用,并且进一步完善水处理理论科学。

The grave situation of water resource in China at present is pointed out by summarizing the reserve and consumption. The water resource is highly inadequate because the surface runoff has reduced day by day, the groundwater runoff has been mined blindly. Water has been polluted seriousey,People have wasted a lot of water, The wastewater reuse is necessary, important and porssible To counter arduousness in the wastewater treatment, the article puts forward a principle about circulating econolmy in the treatment of industrial wastewater, developing new technology in order to reduce cost and heighten treating ratio of the sewage disposal in city, and perfect further the theory in wastewater treatment.
