Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment device for removing nitrogen and phosphorus. Background Art

[0002] After searching, the Chinese patent authorization number CN217868256U discloses an integrated denitrification and dephosphorization sewage treatment device, including a device body, the bottom of the device body is fixedly connected and connected with a sludge pipe, the left and right sides of the device body are respectively fixedly connected and connected with a water inlet pipe and a drain pipe, the center of the top of the device body is fixedly connected with a motor, and the output shaft of the motor is fixedly connected with a shaft rod. Through the set feed pipe, the motor drives the shaft rod to rotate, and the fixed rod will also rotate with the rotation of the shaft rod. When the second magnetic block at the end of the fixed rod moves to the outside of the feed pipe, the second magnetic block will attract the cylinder to move along the feed pipe, so that the magnesium salt inside the feeding funnel falls into the inside of the feed pipe. After the second magnetic block leaves the feed pipe, the cylinder resets to break up the magnesium salt inside the feed pipe and pushes it out of the feed pipe, and a small amount of magnesium salt is added each time, so that the dissolution rate of magnesium salt can be improved, and the efficiency of sewage purification can be improved.

[0003] The integrated denitrification and dephosphorization sewage treatment device in the above patent has the following shortcomings: when the stirring blade stirs the sewage, the stirring blade needs to have a faster rotation speed, so the rotation speed of the shaft will also be faster, and the speed of the second magnetic block will also be very fast. Due to the fast speed, the second magnetic block can only attract the first magnetic block for a very short time, and it cannot be guaranteed that the second magnetic block can stably attract the first magnetic block every time it moves close to the first magnetic block so that the first magnetic block can pull the spring. It cannot be guaranteed that the magnesium salt can be stably broken up and discharged into the sewage, and the stability is low. Therefore, it is necessary to design a denitrification and dephosphorization sewage treatment device to solve the above problems. Utility Model Content
