Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to an MBR membrane sewage treatment equipment with an inner wall impurity cleaning function. Background Art

[0002] During the operation of the MBR system, pollutants such as sludge, organic matter, and inorganic matter will gradually accumulate on the membrane surface, resulting in a decrease in membrane flux. Backflushing cleaning can effectively remove these pollutants and restore the filtration performance of the membrane. Regular backflushing cleaning can reduce the degree of membrane contamination and reduce the frequency of membrane replacement, thereby extending the service life of the membrane and reducing the operating cost of the equipment.

[0003] At present, most of the sewage treatment methods are chemical treatment methods, and the whole process is too cumbersome and takes a lot of time. At the same time, the water quality testing process is also relatively troublesome. At the same time, the cleaning of the reaction pool after the sewage treatment is completed is also a large workload, which takes up a lot of time and manpower, increasing the cost of sewage purification.

[0004] Chinese patent CN208995194U discloses a high-efficiency cleaning MBR membrane reactor with gas-water backwashing, including a reactor body and a SIN-PTU200 online turbidity detector. A water injection port is provided on one side of the top of the reactor body, a support leg is welded to the bottom of the reactor body, and a wash port is provided in the middle position of the bottom of one side of the reactor body. In this utility model, during the sewage treatment process, the MBR membrane is a highly efficient biofilm. When sewage is injected into the reactor body from the water injection port, the microbial membrane absorbs organic pollutants in the sewage as nutrients for its own metabolism, and under the condition of providing aeration and oxygen supply at the bottom of the filter material layer, the gas and water are both in an upward flow state, so that the organic matter in the wastewater is aerobically degraded and nitrification and denitrification are carried out. It regularly uses the treated effluent to backwash the filter tank to remove the aging microbial membrane that proliferates on the surface of the filter material to ensure the activity of the microbial membrane.

[0005] In response to the above problems, existing patents have provided solutions. However, when the MBR membrane is backflushed to clean it, the sewage will accumulate inside the equipment chassis. When the MBR membrane is in use, water needs to be run inside the chassis at all times to avoid dry damage. Therefore, if the stains in the sewage are not cleaned in time, it will cause secondary pollution when the cleaned sewage is introduced, thereby increasing the pressure on the equipment sewage treatment.

[0006] Therefore, an MBR membrane sewage treatment equipment with inner wall impurity cleaning function is proposed. Utility Model Content
