摘要:建筑物内用水器具后至污水处理厂为整个污水集输管道系统，包括建筑排水立管、化粪池、地下重力流管道3部分，通常分为建筑小区排水和市政排水2大系统。污水集输管道系统普遍关注的问题是臭味扩散、管道腐蚀和爆炸事故，这些问题均与管道中气流组织密切相关。为有效缓解管道系统气体危害性，采用系统分析的方法，从整个污水集输管道系统角度出发，分别探讨了3部分气体运动状况与流动特点，以及3部分管道之间气体流动的相互联系，提出了解决污水管道系统有害气体问题的新思路，并对未来有害气体控制相关研究方向进行展望。

Abstract:The whole sewage collection and transportation pipeline system is between the end of water appliances in the building and the sewage treatment plant, including three parts: the building drainage riser, septic tank, underground gravity flow pipeline. It is divided into the construction community drainage and municipal drainage. The common concerns about sewage collection and transportation pipelines are odor diffusion, pipeline corrosion and explosion accidents, all of which are closely related to airflow organization in the pipeline. Thus, in the perspective of the whole sewage collection and transportation pipeline system. in order to alleviate effectively the gas hazard of pipeline system, the system analysis method was used to discuss the gas movement and flow characteristics in above three parts, and the interrelation of gas flow among the pipeline of these three parts, respectively. Then a new way to solve the problem of harmful gas in sewage pipeline system was proposed, the prospect of the future research directions to harmful gas control was also predicted.
