Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically, to a biological purification membrane group device. Background Art

[0002] The MABR membrane aeration biofilm reactor is an innovative biological treatment technology that combines the advantages of membrane technology and biological treatment processes. This technology has broad application prospects in the fields of sewage treatment, wastewater treatment, and resource recovery.

[0003] It is internally provided with oxygen-permeable hollow fiber membrane filaments: This is the core of MABR technology and is usually made of hydrophobic materials such as polytetrafluoroethylene (PTFE), polypropylene (PP), etc. These membrane materials have tiny pores that allow air (oxygen) to pass through but prevent water molecules and suspended solids from passing through. The microporous aeration membrane directly supplies oxygen to the biofilm attached to the membrane surface, improving the oxygen transfer efficiency and biological treatment efficiency.

[0004] However, for the current biological purification membrane group device, the fixation of the oxygen-permeable hollow fiber membrane filaments is mainly completed through a support device. After being sunk into the sewage, the required working depths of the sewage at different depths are different. In order to meet the requirements of sewage treatment depth, the method of advance customization is mostly adopted.

[0005] However, since the depth of the water body in the municipal river channel fluctuates with the seasons, the oxygen-permeable hollow fiber membrane filaments exposed to the air are difficult to achieve the effect of water body purification. After forcibly adjusting the height of the support device, problems such as stacking and extrusion of the internally provided oxygen-permeable hollow fiber membrane filaments will occur, affecting the contact area between the oxygen-permeable hollow fiber membrane filaments and the sewage, and thus affecting the purification effect of the biofilm on its surface on the water body. In view of this, we propose a biological purification membrane group device. Summary of the Utility Model

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a biological purification membrane group device to solve the technical problem that after forcibly adjusting the height of the support device in the current biological purification membrane group device, the oxygen-permeable hollow fiber membrane filaments arranged inside will appear stacked and extruded, affecting the contact area between the oxygen-permeable hollow fiber membrane filaments and the sewage, and thus affecting the purification effect of the biofilm on its surface on the water body.
