[0002] Granite is also known as synthetic stone, reconstituted stone, and engineered stone. It uses natural marble chips and stone powder as the main raw materials, and can also add materials such as shells and glass as embellishments. With organic resin as the binder, it is made into square materials through vacuum stirring and high-pressure vibration, and then made into plates through processes such as room temperature curing, sawing, grinding, and polishing.

[0003] During the production process, processes such as sawing, grinding, and polishing usually require a large amount of water for cleaning. However, if the sewage generated by these activities is discharged to the outside for a long time, it will cause serious environmental pollution and water resource waste problems. Currently, the common sewage treatment method is to dig multiple sewage sedimentation pits and try to recycle water resources through multi-stage sedimentation. However, this method has some problems: the sedimentation pits occupy a large amount of ground space, and their purification effect is limited. In addition, periodically cleaning the sedimentation pits is not only time-consuming and laborious, but also affects the normal production operation of the enterprise. Content of the Utility Model
