Abstract

The invention provides a composite strain biological fluidized bed membrane reactor, which comprises a plurality of reaction tanks, a biological membrane carrier and an aeration mechanism, and is characterized in that the biological membrane carrier is provided with composite strains, and the composite strains comprise composite oil removing bacteria, composite phosphorus accumulating bacteria, composite denitrifying bacteria and composite desulfurizing bacteria. Preferably, the composite oil removing bacteria comprise bacillus, saccharomycetes and micrococcus, the composite phosphorusaccumulating bacteria comprise aeromonas, pseudomonas and acinetobacter, the composite denitrifying bacteria comprise nitrosomonas and nitrobacter, and the composite desulfurizing bacteria comprise thiobacillus, pseudomonas and acinetobacter. By the adoption of the above scheme, petroleum, gasoline hydrocarbons, phosphorus-containing substances, ammonia nitrogen, nitrites and sulfides in water can be wellremoved, rapid establishment of nitrifying bacteria, phosphorusaccumulating bacteria and desulfurization bacteria in a sewage system is promoted, and the effluent quality is improved.

Description

technical field

[0001] The invention relates to the technical field of sewage treatment, in particular to a biofluidic bed membrane reactor of composite bacteria. Background technique

[0002] At present, there are two main types of sewage treatment methods: activated sludge method and biofilm method: the activated sludge method has been developed in Britain since the early 20th century. The sewage treatment effect has gradually become a relatively mature process recognized by everyone; the biofilm method is a process that uses organisms attached to the filler to purify the water body, and it has also been rapidly developed and improved in recent years. The biofilm method makes up for many shortcomings of the activated sludge method, such as its good stability, strong ability to withstand the impact of organic load and hydraulic load, no sludge bulking, no reflux, high removal rate of organic matter, and the volume of the reactor Small size, small footprint of the sewage tr...
