城市生活污水处理技术现状及发展趋势

Present Situation and Development Trend of Municipal Domestic Sewage Treatment Technology

改革开放以来,随着城市不断发展,建筑、化工等行业大量兴起使水资源受到越来越多的污染,污水中的污染源也在快速增多,导致水污染和周边环境污染问题日渐凸显和严峻,因此全面地展开污水处理技术的应用和加强技术的效用是急切需要的。本文介绍了城市生活污水的基本特点,重点分析了污水处理工艺的使用状况和适用条件,并对其具有的优势和局限性进行了对比分析,最后探讨了该处理技术的发展方向。

Since the reform and opening up,with the continuous development of the city,the rise of a large number of construction and chemical industry make more and more pollution in water resources,sewage pollution sources are rapidly increasing,leading to water pollution and environmental pollution problems become increasingly prominent and severe.Therefore,it is urgently needed to fully develop the application of sewage treatment technology and to enhance the effectiveness of technology.The basic characteristics of municipal sewage were introduced,the use of sewage treatment process and the application of the conditions were analyzed,its advantages and limitations were comparative analyzed,and the development of the processing technology was discussed.
