In fact, strictly speaking, the sewage from the concrete mixing plant is not sewage, it only needs to be treated before use.
The water used for cleaning the mixing machine and the water used for cleaning the mixing truck all contain a certain amount of cement, coal ash, sand, and aggregates. Generally, it needs to be separated by a sand and gravel separator through channels or pipelines, and the sand and gravel aggregates are then introduced into a sedimentation tank for sedimentation before entering the reuse sewage tank.
After sedimentation, the wastewater on the surface can be reused as it contains admixtures that have no adverse effects on the production of concrete. This can reduce costs. In addition, the reused clean water can also wash and reduce dust on the site, maintaining a clean environment.
By treating sewage from concrete mixing plants, not only can the damage to the surrounding environment be reduced, but also the cost of cleaning the site can be reduced, making efforts for the environmental protection of construction projects.
