With the increasing demand for sand and gravel in China, the development of natural sand is facing the pressure of resource reduction and environmental protection. Washed sand has become an important source of construction sand in the building materials market. Washed sand can be widely used in concrete, mortar and products.

[0003] Sand washing mud is generally made of raw materials such as crushed stone, stone powder, cement, etc. The main components of the mud are water and clay. In the sand washing process, in order to ensure the efficiency of sand washing, a large amount of water and clay are needed. The amount of water and clay content of sand washing will gradually increase as the construction progresses, and the mud residue washed down will also increase accordingly. The sand washing mud contains a large amount of water and clay components, which is easy to cause caking during the sedimentation and drying process. In addition, a large amount of wastewater will be generated during the sand washing process. If these wastewaters are directly discharged into the environment without treatment, they will cause environmental pollution. The wastewater treatment system in the prior art is prone to blockage when treating wastewater, and when the impurities reach a certain amount, they cannot be cleaned up in time, which greatly reduces the efficiency of equipment treatment and also increases other costs.
