This study takes the design of a sewage pipe network in a town and its industrialpark in Hebei as an example. In order to optimize the planning and design of the sewagepipe network system and improve the drainage efficiency, according to the localconditions, the sewage project has been planned as a whole and the sewage pipe iscompleted. The network planning and design provides technical support for the qualityassurance of the regional water environment.
In the process of designing the sewage pipe network, in order to make thearrangement of the sewage pipe more reasonable, fully consider the use of the currentterrain. Most of the sewage pipelines are laid by means of gravity flow. Only thepipelines crossing the river use the pumping station to upgrade. The lifting pump stationuses an integrated pumping station. The pipeline crossing the river considers the doublepipeline to cross the river. The way of rain and sewage in the township area, after theanalysis of the actual situation, the pipeline system can be directly changed into theform of rain and sewage diversion; the laying of the pipeline is the most common directburial method, and for the laying of the pumping station When the water outlet pipe isused, the pressure inspection wells also need to be arranged, generally one is arranged atabout 120 m.
In addition, the auxiliary facilities arranged together include an exhaustwell and a drainage well. The sewage is sent to the sewage treatment plant of the parkfor treatment after the planned sewage pipe network. The recommended treatmentprocess is SBR process. It is expected that after the implementation of the project, therole of the pipe network collection system will gradually emerge. The collectionefficiency of sewage in the area will be greatly improved, and the sewage dischargeddirectly into the river will also have obvious changes, thus making the town And thechemical environment of the chemical park has a qualitative change in the good aspects,and the positive effect of the sewage pipe network system can be better displayed.
The construction and improvement of the sewage pipe network will have a positiverole in the present and future, not only to improve the living environment of localpeople, but also to improve people's living standards and maintain the balance of thedownstream urban ecological environment. Sustained development has also played alarge role in promoting.
