摘要
城市污水处理厂通常因散发气味和影响景观而易成为周边地块升值、商业开发的限制因素,地下式污水处理厂的集约化构造模式可改变这一困境,但存在技术、投资成本等方面的问题,导致污水厂布置方案的比选成为难题。本文以重庆市广阳岛污水处理厂为例,采用成本效益分析方法对2种布置形式进行方案比选,利用影响区域内外的房价差值对外部效益进行量化,采用净现值法对综合效益进行评估,研究结果表明,地下式双层加盖污水厂为广阳岛最佳推荐方案。研究为类似工程方案比选提供参考。
Urban sewage treatment plant is a limitation to estate price and business development due to the stink and landscape devastation, thanks to the intensive underground sewage treatment plant, this trouble can be pulled out. However, underground wastewater treatment plant has problems such as technology, investment cost, so how to adjust layout option to local conditions becomes a dilemma. In this paper, combined with Guangyang Island sewage treatment plant of Chongqing city, several schemes were evaluated by cost-benefit analysis method, while external benefit were quantized by the house price difference between the influenced area and outside, and the comprehensive benefit were evaluated by the net present value. The result showed that the underground sewage treatment plant was the recommended scheme for Guangyang Island, which provided reference for scheme selection and similar projects.
