Technical Field

The utility model belongs to the technical field of sewage treatment's technique and specifically relates to a but MBR membrane cleaning system of hoist and mount formula is related to.

Background

MBR is also called membrane bioreactor, which is a novel water treatment technology combining an activated sludge process and a membrane separation technology. The MBR membrane has high concentration of activated sludge, large volume load and land saving; the solid-liquid separation efficiency is high, and the effluent quality is good; the sludge age is long, and the amount of residual sludge is small; good denitrification effect and the like. The method is widely applied to the aspect of sewage treatment at present.

However, when the MBR membrane is used, in order to ensure a good treatment effect, the membrane needs to be cleaned off-line regularly. In the conventional cleaning operation, each membrane is manually removed, the membrane is placed in a designated membrane cleaning pool and is soaked and cleaned by using medicines, and after the membrane is cleaned, the membrane is installed in the membrane group again. The method has the advantages of large manual operation amount, easy accident occurrence and high membrane loss rate.
