水污染现状及其处理的新技术
【摘 要】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。面对如此嚴重的水污染状况，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。
【Abstract】With the rapid increase of the national economy and the population， the problems about water supply，demand and pollution are becoming more and more serious. Through the investigation， there are nearly 90% of the rivers which flowing the cities are contaminated by varying degrees. To detect surface and ground water in several cities， it is easy to find that the composition of pollutants in the water are complex and the pollutants have obvious complex characteristics. In other words， there are hundreds or even several hundreds of pollutants in the water， including organic matter， nitrogen， phosphorus， heavy metals and other pollutants. Facing a serious water pollution situation， our government has adopted a variety of technologies to treat and control the water pollution. In this paper， we describe the current water treatment technology briefly， and do the prospects for the development of water environment and water pollution in China.
