An asphalt mixing plant has to go through many processes in the process of producing concrete, such as concrete, sand, etc. These materials are generally exposed to the outside immediately. If there is a heavy rain, a large amount of rainfall will wash the road surface, resulting in water-containing concrete and mud. Sandy sewage, if this kind of sewage cannot be properly treated, will pollute the surrounding water resources and the natural environment of people's basic necessities of life. In fact, a sewage collection tank can be built in the concrete mixing plant, which can be used for production and manufacturing after sedimentation, which can save resources and maintain the natural environment.
