Description

[technical field]

[0001] The invention relates to a biological treatment technology, in particular to an MBR membrane biological treatment technology in which activated carbon is used as a carrier and engineering bacteria are added. [Background technique]

[0002] At present, in the MBR membrane biological treatment process, conventional activated sludge is used as inoculation sludge for domestication and cultivation. Due to the interception effect of the MBR membrane, it is very effective in preventing sludge loss and increasing the sludge age and sludge concentration. Therefore, the MBR process has a short commissioning period, stable operation, relatively high COD removal rate, clear effluent, and good water quality. However, for some industrial wastewater with complex water quality, poor biodegradability, and high drainage requirements, the MBR treatment effect is unsatisfactory, and there are few application cases.

[0003] In order to improve the treatment effect and ...
