[0003] After massive searches, it was found that the prior art publication number is CN215627458U, which discloses an efficient facility for rural domestic sewage treatment. Impurities in domestic sewage are filtered out through the inclined filter plate in the filter pool. The microorganisms in the activated sludge in the treatment pool can decompose organic matter in domestic sewage. Aquatic plants carry out photosynthesis, which can enhance the activity of microorganisms and speed up the treatment efficiency. The blower can suck the odor in the wastewater into the deodorization box and adsorb it through the activated carbon in the deodorization box, so that the facility can treat domestic sewage, solving the problem that rural areas have not achieved direct discharge of sewage treatment or have insufficient treatment efforts, resulting in sewage polluting the surrounding soil and air.

[0004] Therefore, based on the above search and combined with the existing technology, the existing rural domestic sewage treatment methods often lack effective treatment facilities and technologies, resulting in sewage being directly discharged into rivers, lakes and other water bodies, seriously polluting the environment and threatening people's health. In addition, the existing rural domestic sewage cannot be filtered when it flows into the regulating tank, affecting the regulation efficiency. Utility Model Content
