苏州新区城市污水处理厂的生态足迹分析

An Ecological Footprint Analysis on Municipal Wastewater Treatment Plant in Suzhou New District

生态足迹分析法能定量揭示污水厂的生态状况。文章以苏州新区城市污水厂的处理工艺和运行数据为例,分析计算了该厂能耗、污泥、垃圾和交通等四方面的生态足迹。结果表明,该厂2008年总生态足迹为1 071.868 1hm2,人均污水处理生态足迹为0.005 4 hm2。并从生态足迹角度为污水厂的节能减排与可持续发展提出建议。

The ecological footprint analysis can quantitatively reveal the ecological condition of a wastewater treatment plant.Taking the treatment and operation data in Suzhou New District Municipal Sewage Treatment Plant as an example,the paper presents the four ecological footprints including the energy consumption,sludge disposal,solid wastes and traffic.The results show that the ecological footprint of the plant in 2008 was about 1 071.868 1 hm^2 and the ecological footprint by per capita was 0.005 4 hm^2.The paper also gives some sugges-tions on the energy saving and sustainable development.
