Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment tower. Background Art

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. It is also increasingly entering the daily lives of ordinary people. Sewage treatment towers are usually used for sewage treatment.

[0003] Patent publication number CN221479664U discloses an integrated sewage treatment tower. When treating sewage, air is transported into the aeration bin through an aeration assembly to aerate the sewage inside the aeration bin. The aerated sewage flows into the purification bin, and the flocculant inside the reagent tank enters the purification bin through a discharge pipe. The drive motor is energized to drive the stirring rod to rotate, stirring and mixing the sewage and flocculant inside the purification bin, causing impurities in the sewage to chemically react with the flocculant, thereby achieving the purpose of improving the sewage treatment efficiency of the sewage treatment tower. However, due to the reaction between the flocculant and the sewage, the suspended solid particles in the water can be aggregated to form larger particles and precipitated on the bottom wall of the tower body. When cleaning the sludge impurities, it is discharged by opening the drain valve. However, a large amount of sludge impurities are deposited on the bottom wall of the tower body and are not fully discharged through the drain valve, making it impossible to fully clean the sludge impurities on the bottom wall of the tower body. For this reason, we have proposed a sewage treatment tower. Utility Model Content
