[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This centralized rural sewage treatment device, through its filter box, purification box, feed rack, discharge rack, return pipe, extraction pipe, return seat, return pump, extraction seat, and extraction pump, enables the equipment to perform a more suitable centralized and cyclical treatment of rural sewage. In actual use, the staff first injects the rural sewage to be treated into the filter box, where the sewage is filtered by the equipment. At this time, the extraction pump on the side of the extraction seat is activated, working in conjunction with the extraction pipe to extract the sewage from the bottom discharge rack of the filter box and send it into the purification box, where it is purified by the equipment. Simultaneously, the purified impurities are directly circulated back into the filter box by activating the return pump on the side of the return seat for centralized treatment. Daily maintenance only requires cleaning the inside of the filter box to remove debris, thus achieving a more efficient centralized treatment of rural sewage and demonstrating the practicality of the equipment design.

[0015] This centralized rural sewage treatment device, through its filter box, purification box, first metering device, second metering device, sealing cover, liquid control valve seat, feed trough, uniform material ring grid, installation groove, and installation inner tank, further improves the overall performance of the equipment. During daily use, operators can install the return material seat, return material pump, and extraction material seat and pump at the feed racks at the top of the filter box and purification box, respectively. The feed rack, through the uniform material ring grid in the internal feed trough, ensures more even feeding, assisting in more uniform and efficient sewage treatment. Furthermore, the first and second metering devices between the return and extraction pipes allow for efficient metering of sewage at each stage. Simultaneously, the interiors of the filter box and purification box can be efficiently switched using the installation inner tank in the installation groove, facilitating maintenance of the centralized rural sewage treatment system and demonstrating the comprehensiveness of the equipment design.
