[0002] Urban sewage treatment plants are one of the key environmental engineering systems, which aim to reduce the pollution of natural water bodies (rivers, lakes, oceans, etc.) caused by sewage discharge. These systems are usually designed to treat urban domestic sewage and industrial wastewater to ensure the ecological safety of water bodies and human health safety.

[0003] After searching, a city sewage treatment device with announcement number CN215886609U is found. The utility model relates to the technical field of sewage treatment. The city sewage treatment device comprises: a treatment box, a stirring chamber is arranged at the upper end inside the treatment box, and a sedimentation chamber is arranged at the lower end inside the treatment box; first, the sieve plate is taken out from the sedimentation chamber to the left, and then the connecting rod is rotated clockwise by the pull ring, and the connecting rod drives the limit rod to move from the first card slot to the position of the second card slot, and then the connecting rod can be removed by moving it to the left, and then the impurities on the sieve plate can be cleaned, and then the connecting rod is reinserted into the through slot and the limit rod is embedded in the second card slot, and then the connecting rod is rotated counterclockwise and the limit rod is inserted into the first card slot, and then the right end of the sieve plate is inserted into the sedimentation chamber, which can quickly complete the treatment of impurities on the sieve plate, and the operation is simple. Through the treatment of impurities on the sieve plate, the sieve plate can better filter the sewage impurities, so as to facilitate the sedimentation treatment of the sewage.

[0004] Based on the above patent, by first pulling the pull ring to the left and making it drive the protective plate and the sieve plate to move to the left, and letting the sieve plate be taken out of the sedimentation chamber to the left, then rotating the connecting rod clockwise through the pull ring, and letting the connecting rod drive the limiting rod to move from the first slot to the position of the second slot, because the connection method between the connecting rod and the sieve plate is the same as the connection method between the connecting rod and the protective plate, the connecting rod will be detached from the left end of the sieve plate, and then the connecting rod can be removed by moving it to the left, and then the impurities on the sieve plate can be cleaned, and then the sieve plate is stuck into the right side surface of the protective plate, and then the connecting rod is reinserted into the through slot and the limiting rod is embedded in the second slot, and then the connecting rod is rotated counterclockwise and the limiting rod is Insert the card into the card slot one, and then insert the right end of the sieve plate into the sedimentation chamber, which can quickly complete the treatment of impurities on the sieve plate. The operation is simple. By treating the impurities on the sieve plate, the sieve plate can better filter the sewage impurities to facilitate the sedimentation treatment of the sewage. However, when the stirring blade of the above-mentioned patent stirs the sewage, since the stirring blade uses a unidirectional stirring method, the stirring efficiency is low when the sewage is treated with chemicals. Stirring is particularly important for the biochemical link in sewage treatment. For example, in the activated sludge treatment process, if the stirring efficiency is insufficient, it will cause uneven distribution of dissolved oxygen in the pool, affecting the metabolic efficiency of microorganisms to pollutants, thereby causing instability in the biochemical process and reduced treatment effect.
