With people’s increasing efforts in waste classification and environmental protection, the whole world is asking for environmental protection. Reduce takeaway waste, reduce white pollution, reduce express boxes and so on. But for construction projects, machinery and equipment is essential, only to say that in the choice as much as possible to use some environmentally friendly equipment. Concrete mixing plant is now a kind of equipment used in construction sites, so how to choose an environmentally friendly concrete mixing plant?
As we all know, concrete mixing plant is composed of 5 major systems such as mixing host, material weighing system, material conveying system, material storage system and control system and other ancillary facilities. Since the building aggregate metering reduces four intermediate links compared with the station aggregate metering, and it is vertical down metering, which saves the metering time and therefore greatly improves the production efficiency. How to choose an environmentally friendly concrete mixing plant depends on its sewage transformation and treatment system.
In the process of concrete production, the cleaning of equipment and vehicles generates a large amount of sewage, which is harmful to the environment when discharged directly. This is why the wastewater treatment system in concrete production will recycle the wastewater and achieve zero discharge standards. The wastewater treatment system mainly includes the concrete transport fleet unloading chute, gravel separator equipment, sewage sedimentation tank, sewage tank mixer, clarifier, conveying pump, filter press, etc. The whole drainage in the concrete mixing plant is transformed so that the sewage does not flow out of the plant, and the treated sewage is directly supplied to the mixing plant for use and vehicle cleaning after inspection, and the waste slag produced can be used as added aggregate. The treated waste water can also be used as added aggregate. The treatment of zero discharge of sewage is realized.
