人工湿地处理污水技术及其在我国的应用现状和对策

随着社会工业的发展，世界人口的急速膨胀以及城市化进程的加速，人类水资源利用的矛盾日益突出，人类可利用的水资源变得十分有限。为了解决此问题，改善水质和水生生态系统的恢复成为了目前极为紧迫的任务。自人工湿地污水处理系统于20世纪70年代初首次在德国投入使用后，

Man-made Wetland Sewage Technologies and Their Application:Present State and Policies

This paper introduces the concept, principles, classification and structure of man-made wetland. Based on several international cases of treating sewage by man-made wetland, the paper focuses on the current state, advantage, problem and development trend of live water technologies by man-made wetland. It is believed that man-made wetland, as a new kind of ecological sewage treatment technics, has outstanding advantages in technological design, engineering technologies, economic interest, and beautification of the environment. But the sewage treatment technologies by using man-made wetland also have many limitations and shortcomings in its development and applications. According to the current state and development of the technologies in China, several measures are set forth, including (a) to develop and establish man-made wetland database, (b) to enhance the research and development and application of the related technologies, (c) to pay more attentions to the local resources; and (d) to explore the market operation mode of ecological sewage treatment technologies by using man-made wetland.
