Abstract： |
The present invention belongs to the field of water and waste water treating and purifying technology, and is one kind of on-line chemical cleaning method for controlling the membrane contamination of membrane bioreactor. The chemical cleaning method has alkali washing as the main part and acid washing as the auxiliary part, and for membrane bioreactors of different sizes, two different cleaning modes are recommended. The method can eliminate membrane pore jamming caused by macro molecular organic matter and colloid matter and gel contamination effectively to restore the filtering capacity of the membrane, and has simple operation and low maintenance cost. Applying the method can realize the long term stable operation of the membrane assembly, prolong the service life of membrane assembly and lower the maintenance cost of membrane assembly. |
