真空排污系统在地铁中的应用

摘要

通过比较湿式污水提升系统、一体化污水提升系统以及真空排污系统三者的优缺点,指出地铁建设中的污水提升采用真空排污系统的可行性及必要性.真空排污系统既解决了传统污水泵房气味恶臭的问题,同时也较好地解决了一体化污水提升系统存在的后期检修维护问题,在地铁车站的应用前景看好.真空排污系统也存在价格相对较高、施工精度要求高、真空技术方面需要作进一步完善等问题.%With a comparison among the wet,the integrated and the vacuum sewage promotion systems, the article points out that,in subway construction,the adoption of vacuum sewage promotion system is of higher feasibility and urgent necessity,becauses this system could reduce odor smell from the sewage pump house,and have quite convenient overhauls. Therefore, the vacuum sewage promotion system has prospective application at subway station,but the costly price,strict construction-precision and the improvement of vacuum engineering shall be also put into consideration.
