我国地下污水处理厂建设现状及展望

The Current Status and Prospect of Underground Wastewater Treatment Plant in China

为应对稀缺土地资源限制和满足更高生态环境需求,我国城市污水处理厂建设开始向地下寻求空间。对我国近年来刚刚兴起的地下污水处理厂工程实例进行全面调查分析,揭示其在占地、投资、厂址、工艺、地面功能设计等方面与传统地上污水处理厂的不同特点,并对地下污水处理厂未来发展趋势、关注重点和突出作用进行展望。

When land resource is a limited factor in China,the municipal wastewater treatment plants( WWTPs) have to be built under the ground to save space required. Additional driving force of underground WWTP construction lies in protecting the integrity of the above-ground ecological environment. Recently,many underground WWTPs have been constructed in China. According to the overview of these underground WWTPs,the differences between the underground WWTPs and the traditional above-ground WWTPs in terms of the space requirement,investment,plants site,technology,functional application of ground design were compared and discussed in this paper. The prospect of the underground WWTPs including the future developing trend,attention focuses and the prominent role was also presented.
