真空排水技术在老城区雨污分流工程中的应用
- Title:
- Application of Vacuum Drainage Technology in Rainwater and Sewage Diversion Project in Old Urban Area
- 摘要:
- 雨污分流是提升老城区环境的有效措施之一,但老城区一般地下管线复杂,采用传统重力排水技术施工改造难度较大。潍坊滨海老城区雨污分流改造项目采用真空排水技术进行污水收集,相比重力排水技术,在管网施工与维护中均体现出了明显优势。介绍了系统雨污分流改造方法及污水量、真空泵站、收集箱、真空管道及电气系统的设计关键点,可为类似工程提供借鉴。
- Abstract:
- Rainwater and sewage diversion is one of the effective measures to improve the environment of the old urban area. However, the distribution of the underground pipelines are complex in the old urban area. It is difficult to reconstruct the pipelines by using the traditional gravity drainage technology. In Weifang Binhai old urban area, the vacuum drainage technology is used for sewage collection in rainwater and sewage diversion reconstruction project. It shows obvious advantages in pipe network construction and maintenance comparing with gravity drainage technology. The transformation method of rainwater and sewage diversion, and the design key points of sewage volume, vacuum pumping station, collection box, vacuum pipeline and electrical system were introduced, which can provide reference for similar projects.
