Research On Wastewater Engineering Design Of A Chemical Park And Town

The construction of urban pipe network infrastructure plays a vital role in the development of the town now and in the future.Along with the development of the town and the rapid increase of population,the discharge of sewage has also increased significantly.In this case,the planning and design of the drainage network is very important.This study takes the design of a sewage pipe network in a town and its industrial park in Hebei as an example.In order to optimize the planning and design of the sewage pipe network system and improve the drainage efficiency,according to the local conditions,the sewage project has been planned as a whole and the sewage pipe is completed.The network planning and design provides technical support for the quality assurance of the regional water environment.In the process of designing the sewage pipe network,in order to make the arrangement of the sewage pipe more reasonable,fully consider the use of the current terrain.Most of the sewage pipelines are laid by means of gravity flow.Only the pipelines crossing the river use the pumping station to upgrade.The lifting pump station uses an integrated pumping station.The pipeline crossing the river considers the double pipeline to cross the river.The way of rain and sewage in the township area,after the analysis of the actual situation,the pipeline system can be directly changed into the form of rain and sewage diversion;the laying of the pipeline is the most common direct burial method,and for the laying of the pumping station When the water outlet pipe is used,the pressure inspection wells also need to be arranged,generally one is arranged at about 120 m.In addition,the auxiliary facilities arranged together include an exhaust well and a drainage well.The sewage is sent to the sewage treatment plant of the park for treatment after the planned sewage pipe network.The recommended treatment process is SBR process.It is expected that after the implementation of the project,the role of the pipe network collection system will gradually emerge.The collection efficiency of sewage in the area will be greatly improved,and the sewage discharged directly into the river will also have obvious changes,thus making the town And the chemical 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 positive role in the present and future,not only to improve the living environment of local people,but also to improve people's living standards and maintain the balance of the downstream urban ecological environment.Sustained development has also played a large role in promoting.
