[0002] The main pollutant in glass deep processing wastewater is SS, which has a large density and a wide particle size distribution range, basically between 0.5um-100um. Large particles are easy to sink, while small particles are suspended in the water due to the action of water molecules and are difficult to remove.

[0003] Existing integrated glass sewage treatment machines usually need to be equipped with large sedimentation tanks when treating large-volume sewage. This not only increases construction costs, but also occupies a large amount of land resources. The construction and maintenance of large sedimentation tanks also require a lot of time and manpower, increasing the cost and complexity of overall operations. In addition, when treating sewage, the integrated glass sewage treatment machine has the problem of insufficient slag removal. The treated water still contains a certain amount of suspended matter and impurities, which affects the further improvement and utilization of water quality. Incomplete slag removal can easily lead to internal blockage and increased failure rate of the equipment, affecting the normal operation and service life of the equipment.

[0004] In response to the above technical problems, Chinese patent application number: CN202311835854.7, a glass production wastewater treatment circulation system, through the inclined setting of the upper surface of the pouring table and the connection between the rear side of the pouring table and the water pipe, the sewage entering the filter box can be quickly diverted to the water pipe, thereby improving the system's sewage diversion efficiency; it can adapt to the amount of glass waste and expand its placement space, avoid clogging of the filter screen, and improve the filtration efficiency of the system.

[0005] Although the glass production wastewater treatment circulation system can remove slag, it removes slag by filtering, which is prone to clogging and often requires maintenance, resulting in poor slag removal effect.
