[0002] The wastewater from gelatin and collagen pre-treatment workshops contains a large amount of organic solids, which greatly increase the burden on the sewage treatment system. Therefore, it is necessary to remove the solids in the sewage first to improve the subsequent sewage purification efficiency.

[0003] Chinese patent publication number CN211724916U proposes a gelatin wastewater pretreatment system that easily removes solids adhering to the inner wall of a microfiltration drum, thereby improving wastewater treatment efficiency. The utility model comprises a microfiltration drum, a drive mechanism for rotating the drum, and a sewage cofferdam disposed below the drum. The drum's inlet is provided with a water inlet pipe, and the drum's outlet is provided with a filter residue collection container. The drum's inner wall is provided with a spiral scraper, and the drum's inner wall is provided with filter holes. Key features of the gelatin wastewater pretreatment system include a microfiltration drum flushing device consisting of a nozzle mounted above the drum and a clean water inlet pipe connected to the nozzle. This technical solution's gelatin wastewater pretreatment system incorporates a microfiltration drum flushing device that conveniently removes solids adhering to the drum's inner wall, ensuring the drum's separation efficiency, making it ideal for gelatin wastewater treatment.

[0004] The above technical solution uses the cooperation of a second centrifugal pump, a clean water inlet pipe and a nozzle to flush the microfiltration drum, thereby achieving the effect of flushing residue. The water after flushing is mixed with the sewage, which will lead to the pollution and waste of a large amount of water resources, and will also increase the cost of purifying water resources in the future.
