人工湿地提高动物园水质技术研究

人工湿地由于去污效果好,易维修和运行费用低等特点,已广泛应用到生活污水的处理中。从人工湿地植物的类型及选择原则、去污机理及效果等方面,对人工湿地污水处理技术现状进行综述,对植物在处理生活污水的研究中对不同污染物的净化效果进行了比较。提出了动物园人工湿地的构建,不仅对提高动物福利、保护生物多样性、展现动物和环境的综合美感方面具有重要意义,而且可净化人工湖水,去除水中的BOD5、N、P等污染物质,起到绿化作用,可建立起良好的生态环境。

Techology Research of Improving Zoo Water Quality Using Constructed Wetland

Constructed wetland is widely used in sewage treatment because of its satisfactory decontamination effect, easy maintenance and low operation cost. The status of wetland sewage treatment technologies from constructed wetland type, detergency mechanism and effect etc. was reviewed.The purification effects of the plant on different pollutant in domestic wastewater were compared.It was pointed that foundation of zoo constructed wetland was important to improve animals＇ welfare, conserve the biological diversity showed the beautiful sense of animal and environment,and the water of constructed lake could be purified, BODs, N and P in the water could be eliminated ,thereby so a pleasant ecological environment could be found.
