The invention claims a kind of bamboo charcoal filling membrane biological sewage treatment method, belonging to the technical field of water treatment. The processing method is: the bamboo carbon as filler, taking out the soaked bamboo charcoal is set in the fixed bed reactor as biological filler, the water, the pH value is 6-9, the organic waste water by a membrane bioreactor, air is fixed bed filling rate is 100%, the COD volume load is 0.5-6kgCOD/ (m3-d), a water power staying time is 1-6h. The invention uses biomass bamboo charcoal as filling material, it will not generate secondary pollution, at the same time, the technology combined with the bamboo charcoal adsorption and biodegradable double functions, can prolong the residence time of the pollutants such as a surfactant, so as to improve the water quality. The method of the invention has simple technique, small floor area, can remove in the waste water LAS, ammonia nitrogen, total phosphorus, stable quality and wide application range.
