Description

Technical Field

[0001] The utility model mainly relates to the field of sewage treatment, and in particular to chemically assisted phosphorus removal equipment with recyclable phosphorus removal agents. 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, and is increasingly becoming part of the daily lives of ordinary people.

[0003] Sewage treatment requires adding phosphorus removal agents into the sewage, and mixing the phosphorus removal agents and sewage through phosphorus removal equipment to remove phosphorus from the sewage.

[0004] During the operation of the specific embodiment, the inventors found the following defects:

[0005] However, after the phosphorus removal agent comes into contact with sewage, insoluble phosphate precipitates are formed. The precipitates will accumulate inside the phosphorus removal equipment, causing subsequent sewage to enter the phosphorus removal equipment and be blocked by the treatment equipment, making it impossible for the sewage to flow inside the phosphorus removal equipment.

[0006] It should be noted that the above content belongs to the technical knowledge scope of the inventor. Since the technical content in this field is vast and too complicated, the above content of this application does not necessarily constitute prior art. Utility Model Content

When the dephosphorization agent needs to be mixed with the sewage, the motor is started, and the motor drives the transmission shaft 1301 to rotate. The transmission shaft 1301 drives the second stirring rod 1309 and the first stirring rod 1308 to rotate. The first stirring rod 1308 stirs the dephosphorization agent inside the dephosphorization agent warehouse 10, and the second stirring rod 1309 stirs the sewage inside the diversion shell 1. Then the air pump is started, and the air pump pressurizes the interior of the dephosphorization agent warehouse 10. The pressure pushes the spring telescopic rod 1304 to contract and drive the sealing block 1305 to disengage from the sealing ring 1303, so that a gap appears between the sealing ring 1303 and the sealing block 1305. The dephosphorization agent enters the interior of the diversion shell 1 through the liquid inlet 1306 and the liquid outlet 1307 and mixes with the sewage.
