Description

Technical Field

[0001] This utility model relates to the field of MBR membrane module technology, specifically to an easy-to-clean MBR membrane module. Background Technology

[0002] MBR (Membrane Bioreactor) is a novel water treatment technology that combines membrane separation with biological treatment. It immerses membrane modules in an activated sludge reactor, utilizing the microporous filtration of the membrane to retain suspended solids, colloids, bacteria, and other pollutants in wastewater, thus achieving highly efficient water purification. MBR membranes have a wide range of applications, including domestic wastewater treatment, drinking water treatment, surface water treatment, and seawater desalination pretreatment. MBR membranes feature highly efficient solid-liquid separation, microbial retention, flexible and stable operation control, small footprint, high nitrification efficiency, and high degradation efficiency for recalcitrant organic matter. MBR membrane technology has been widely adopted both domestically and internationally, becoming one of the mainstream technologies in wastewater treatment.

[0003] An MBR membrane module, as disclosed in publication number CN221397535U, comprises a frame, a first aeration section, a second aeration section, a lifting mechanism, and a membrane fiber assembly. The membrane fiber assembly is detachably connected to the top of the frame, and the first aeration section is detachably connected to the bottom of the frame, located below the membrane fiber assembly. A lifting mechanism is fixed to the top of the membrane fiber assembly, and the lifting end of the lifting mechanism is detachably connected to the second aeration section. The aeration end of the second aeration section passes through the membrane fiber assembly. Both the first and second aeration sections are connected to external aeration equipment via flexible hoses. This MBR membrane module, by providing a first aeration section below the membrane fiber assembly and combining it with a second aeration section located inside the membrane fiber assembly, achieves cleaning and rinsing of the membrane fiber assembly from various positions, resulting in uniform aeration. Furthermore, the lifting mechanism allows for height adjustment of the second aeration section, ensuring comprehensive aeration without dead zones.
