Description

MBR membrane cleaning operation car Technical Field The utility model relates to the technical field of cleaning equipment, in particular to an MBR (Membrane biological reactor) membrane cleaning operation vehicle. Background Along with the continuous improvement of environmental protection requirements, higher requirements are put forward on the sewage treatment process and equipment. The MBR process has good mud-water separation effect and high intelligent control level, and can be widely applied to sewage treatment systems. In the existing MBR membrane cleaning technology, a fixed cleaning device is widely adopted, and the cleaning track is single, so that the local area of the surface of the MBR membrane is subjected to the concentrated action of high-pressure liquid or brush friction for a long time, and the abrasion and deformation of the membrane assembly are accelerated. Most cleaning devices can only cover part of the surface area, but edge seams of the MBR membrane are difficult to touch, stubborn pollutants are easy to remain, clean dead zones are formed, and the membrane flux is obviously reduced after long-term accumulation. Traditional cleaning equipment relies on an electric driving system, and potential safety hazards exist in electric devices in a water-involved working environment. Most equipment does not consider the airtight requirement of operation space, and the open type cleaning structure makes sewage leakage risk showing, probably causes secondary pollution and violates environmental protection standard, and above-mentioned technical defect leads to current MBR membrane belt cleaning device to be difficult to realize high-efficient, safe, comprehensive MBR membrane surface cleaning jointly, becomes the key bottleneck of MBR technical popularization.
