摘要
真空排污系统是利用负压管道中的负压梯度将用户处排放的污水逐步输送、收集至真空站后集中处理及排放的污水收集系统。综述了真空排污系统的分类及适用范围,真空的获得及真空检漏测试的标准。介绍了真空排污系统中用户终端的形式和关键阀件。简述了真空排水管网的输送机理。比较了不同的真空罐排放方式及其技术关键。
Vacuum sewerage system is such a system that utilizes the negative pressure gradient in drainage pipeline to collect the wastewater drained off by users and transfer it to vacuum station step by step for centralized treatment.The classification and field of application of vacuum sewerage system are reviewed,as well as the relevant vacuum acquisition and criteria for vacuum leak detection.The forms of terminal users and key valves used in vacuum sewerage system are described,and the conveying mechanism of vacuum sewer networks are briefly surveyed.Moreover,the different ways using vacuum tank(s) to drain sewage and their key technologies are compared with each other.
