人工湿地污水处理技术及其在南京浦口区应用的可行性

人工湿地是模拟自然湿地人为设计建造的,它通过过滤、吸附、共沉淀、离子交换、植物吸收和微生物分解来实现对废水的高效净化.论文从南京市浦口区的地理位置、气候条件、水污染现状及发展趋势、污水处理及需求等方面,分析并论证了人工湿地对污水处理技术在该区的应用及经济可行性.最后对该技术在浦口地区的应用提出了一些实施建议.

Wastewater Treatment with Constructed Wetland and the Feasibility of Its Application in Pukou District of Nanjing City

Constructed wetland is a simulated wetland. The purifying of wastewater depends on a comprehensive result of physical, chemical and biological processes, such as filtration, adsorption, sedimentation, ion- exchange, plant assimilation and micro-organism decomposition. The feasibility of its application in Pukou District of Nanjing City was analyzed and testified based on the aspects of geographic and climatic conditions, water pollution and wastewater treatment at present and their development in the district. Finally, some suggestions were presented for the aoolication of constructed wetland technology in the district.
