海南某半地下污水处理厂海绵城市设计应用

海绵城市是一种新型设计理念,旨在汛期控制并存蓄部分地表径流,随后将其加以利用.因此,它可让城市像海绵一样——在需要的时候可以充分为城市环境吸收或提供水资源.海绵城市理念的实施,既可以满足城市发展的生态环境效益需求,又能给城市建设带来更好的景观效果.以海南省某半地下污水处理厂为例,运用海绵城市设计理念,对厂区雨污水系统进...

Application of Sponge City Design for a Semi-underground Wastewater Treatment Plant in Hainan

Sponge city is a new design idea, is aimed to control and store up the partial surface runoff, and then to utilize it. Thereby, it can let a city as a sponge fully absorb or supply the water resource for the urban environment when in need. The implementation of sponge city idea can not only satisfy the demand of ecological environment benefit of urban development, but also bring the good landscape effect to the urban construction. Taking a semi-underground wastewater treatment plant WWTP in Hainan Province as an example, the design idea of sponge city is used to in the ecological design of rainwater and sewage systems in WWTP, which can reduce the influence of urban WWTP construction on the surrounding ecological environment. The sponge rainwater drainage system mainly includes the permeable pavement, gravel drain, conveying-type grassing ditch and sunken greenbelt.
