水污染现状及其处理的新技术

The Present Situation of Water Pollution and the New Treatment Technology

随着我国国民经济的快速增长和人口数量的迅猛增加,水资源供求及水污染问题日趋严重。经调查,在我国流经城市的河流中,有近90%的受到不同程度的污染。对多个城市的地表、地下水进行检测,我们不难发现水中污染物成分复杂,污染物具有明显的复合特征,即水中的污染物有上百甚至几百种,其中包括有机物、氮、磷及重金属等污染物质。面对如此严重的水污染状况,现阶段国内外已经采用了许多种水处理技术对污水进行处理与控制。论文就现阶段常采用的水处理技术进行简要叙述,并对我国水环境及水污染治理的发展进行展望。

With therapidincrease ofthe nationaleconomyand the population , the problemsabout water supply,demand andpollution are becoming more and more serious . Through the investigation , there are nearly 90% of the rivers which flowing the cities are contaminated by varyingdegrees . To detectsurface and groundwater in several cities , it is easytofindthatthe composition ofpollutants inthe water are complex and the pollutants have obvious complex characteristics . In other words , there are hundreds or even several hundreds ofpollutants in the water, including organic matter, nitrogen , phosphorus , heavymetals and other pollutants . Facing a serious water pollution situation , our government has adopted avariety of technologies to treat and control the waterpollution . In this paper, we describe the current watertreatmenttechnology briefly, and dothe prospects forthe development ofwater environment and waterpollution in China .
