Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a multi-stage filtering device. Background Art

[0002] Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily lives of ordinary people.

[0003] The existing Chinese patent "Multi-stage filtration sewage treatment device" with announcement number CN217895284U proposes that during filtration, sewage enters the filter box from the water inlet, is filtered through the first filter screen and the second filter screen, then passes through the activated carbon layer, and is finally discharged from the water outlet. At the same time, the motor is turned on, the rotation of the motor drives the rotation of the shaft, the rotation of the shaft drives the stirring rod to rotate, and then drives the brush to rotate. The rotation of the brush cleans the first filter screen and the second filter screen. The device can stir the sewage to make it easier to filter. The brush can continuously clean the filter screen during the filtration process to prevent the filter screen from being blocked. The carbon layer can disinfect and sterilize the sewage, thereby improving the sewage treatment efficiency of the sewage filtration device.

[0004] However, in actual use, the applicant found that the device only performs multi-stage filtration of sewage through two filter screens, which is unable to fully and effectively treat the sewage, and the filtration effect is poor and has great limitations. Therefore, we propose a multi-stage filtration device. Utility Model Content
