真空排水系统的原理、方法及应用

Principle,Method and Application of Vacuum Sewer System

真空排水系统是一种新型的排水系统,与传统重力排水系统相比具有环保、节水、节电等优点;真空排水系统安装空间小,可随意绕过障碍物,管道铺设灵活,受地形限制小。国内真空系统应用极少,尚无设计规范和验收标准。该文介绍了真空排水系统的原理、组成及特点,并列举了真空排水系统在国内的一些应用实例,对真空排水系统在国内的应用前景进行了预测。

Vacuum sewer system ,which is environmental friendly, is a new kind of wastewater collection systems. Comparing to the comparing to gravity sewers, vacuum sewer system can save more water and electricity. Vacuum sewer systems need small space and can go around the obstacle easily, thus pipeline of these systems are flexible with no limited by terrain. Till now, vacuum sewer sys- tems are not widely used in China because of no design and acceptance criterion. The principles, units and traits of these systems arc introduced in the paper. Examples of vacuum sewer systems are listed, the forecast of their future use in China is introduced as well.
