High antipollution MBR membrane module

Technical Field

The utility model relates to a high antipollution MBR membrane module belongs to filtration equipment technical field for sewage treatment.

Background

A Membrane Bioreactor (MBR) is a novel sewage treatment device which combines the ultrafiltration and microfiltration membrane separation technology with the biological treatment in sewage treatment. The MBR intercepts microorganism flocs and larger molecular organic matters in the activated sludge mixed liquor by means of the ultrafiltration membrane and the microfiltration membrane, so that the microorganisms are stopped in the reactor, high biological concentration is obtained in the reactor, the retention time of organic solids is prolonged, and the degradation efficiency of the microorganisms on the organic matters is greatly improved. After being treated by the ultrafiltration membrane and the microfiltration membrane, the effluent has high quality and can be directly used for recycling non-drinking water. In practical application, the flat-plate membrane bioreactor is characterized in that a plurality of flat-plate membrane components form a flat-plate membrane unit through a plug-in structure.

Because the curtain type membrane component is often composed of thousands of hollow membrane filaments, the membrane filaments are dense and thick, when the membrane component is used for treating sewage, mud is easily formed among the membrane filaments, and micro-filtration holes are blocked and water cannot flow out. In addition, the MBR membrane module is generally aerated at the bottom of the membrane frame at present, the aeration scouring effect is not ideal, and the MBR membrane module is also one of the main factors which cause the membrane module not to be polluted. And finally, the MBR membrane module must be cleaned after being polluted and blocked, and the conventional membrane module is inconvenient to clean and has high labor intensity.
