Description

Technical Field

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

[0002] With the growth of industrial and agricultural production, population expansion, and the extensive use of phosphorus-containing pesticides and fertilizers, phosphorus pollution in water bodies has become increasingly serious. Phosphorus is one of the key elements that sustain life on Earth and is essential for the formation of organisms and their metabolism. However, if phosphorus levels in water exceed 20 mg / L, it can lead to eutrophication, causing algae blooms. The decomposition of the dead algae can produce a musty and foul odor in the water, affecting the survival of aquatic life such as fish.

[0003] According to the search announcement number CN221544323U, an efficient phosphorus removal and sedimentation device includes a stirring tank and a temporary storage and conveying tank. A stirring motor is fixed on the top of the stirring tank, and a stirring shaft is fixedly connected to the output end of the stirring motor. A vertical scraper and an inclined scraper are fixedly provided on the stirring shaft. The end of the stirring shaft is located at the outlet of the stirring tank and is provided with a dredging auger. Two groups of feeding components are connected to the stirring shaft through a belt on the top of the stirring tank, and a temporary storage and conveying tank is fixedly connected to the bottom of the stirring tank. The feeding components will continuously add the agent into the stirring tank from the two feeding holes, ensuring the continuous and uniform addition of the agent. Under the action of the stirring shaft, the phosphorus removal effect of the sewage is more sufficient. While stirring, the vertical scraper and the inclined scraper will clean the dirt on the inner wall of the stirring tank in time, and then the sediment will be discharged into the temporary storage and conveying tank in time through the dredging auger. The sediment will be pushed into the transportation vehicle for cleaning through the action of the pushing auger and the pushing bucket.

[0004] However, the following problems exist when implementing the above technical solution: the above technical solution is an integrated mixing and stirring device. Due to the single structure of the closed container, only a single chemical phosphorus removal method can be used to remove phosphorus from sewage. The phosphorus removal work of sewage cannot be carried out in stages and multiple groups. The phosphorus removal effect is single, it is not convenient to disassemble and clean, the fault tolerance coefficient is low, the service life is short, and the phosphorus removal effect is limited.
