High-maintainability MBR membrane reaction environment-friendly sewage device and treatment process

Abstract

The invention discloses a high-maintainability MBR membrane reaction environment-friendly sewage device and a treatment process, and belongs to the technical field of sewage treatment, the high-maintainability MBR membrane reaction environment-friendly sewage device comprises an MBR purification tank, an ultrafiltration membrane is arranged in the MBR purification tank, and a cathode plate is arranged at the position, corresponding to the side direction of the ultrafiltration membrane, in the MBR purification tank. According to the invention, under the mutual cooperation of the designed structures such as the ultrafiltration membrane, the cathode plate, the anode cylinder, the valve, the bucket-shaped sleeve, the spherical body, the elastic supporting device and the second threaded cylinder, a certain backflushing effect can be achieved on the ultrafiltration membrane, a large amount of bacteria and suspended solids are prevented from being deposited and attached to the ultrafiltration membrane, and under the action of the mixed flow fan, the to-be-treated sewage just injected can be rapidly mixed with the strains so as to improve the distribution uniformity of the strains in the sewage, and when the number of the strains on the surface of the ultrafiltration membrane is too large so as to affect the water production of the ultrafiltration membrane, the gas inlet amount of the aeration pipe can be improved to perform short-time aeration cleaning, and the aeration is stopped after the partial strains are removed so as to continue the membrane contact oxidation treatment process.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a high-maintenance MBR membrane reaction environmental protection sewage device and a treatment process. Background technique [0002] In the field of sewage treatment and water resource reuse, MBR, also known as membrane bioreactor, is a new type of water treatment technology that combines membrane separation unit and biological treatment unit. According to the structure of the membrane, it can be divided into flat membrane, tubular membrane and Hollow fiber membranes, etc., can be divided into microfiltration membranes, ultrafiltration membranes, nanofiltration membranes, reverse osmosis membranes, etc. according to the membrane pore size.

Problems solved by technology

[0003] In the field of sewage treatment and water resource reuse, MBR, also known as membrane bioreactor, is a new type of water treatment technology that combines membrane separation unit and biological treatment unit. At present, the traditional MBR reactor is still in use. There are some shortcomings. When treating sewage, it is usually necessary to add phosphorus removal agents to the treated sewage. Phosphorus is a substance that is easy to scale. If it is attached to the ultrafiltration membrane, it is difficult to clean it. Even if it is It is also difficult to achieve a high cleaning effect by backwashing technology, which leads to high cost of using ultrafiltration membranes and seriously affects the efficiency of ultrafiltration membranes. Therefore, a high-maintenance MBR is urgently needed in the market at this stage Membrane reaction environmental protection sewage device and treatment process to solve the above problems
