The invention provides ultra-shallow precipitation moving bed biofilm reactor domestic sewage treatment equipment. Fluidized bed fillers are adopted in an anoxic acidification denitrification area, ananaerobic denitrification area and an aerobic suspended bed reaction area; a carrier is provided for microorganisms, the specific surface area for biological reactions is increased, various types ofmicroorganisms can obtain required conditions under the effects of a stirring device, a reflux assembly and an aeration assembly, various types of microorganisms obtain the environment or the substance required by the reactions, and each process unit can realize ammonification, degradation, nitrification and denitrification. The effective utilization rate of space is greatly improved, the removalcapacity of each unit is improved, the treatment reaction time of each treatment unit is effectively shortened, and the occupied area of equipment is reduced.
Description
technical field [0001] The invention relates to the technical field of domestic sewage treatment equipment, in particular to an ultra-shallow sedimentation moving bed biofilm reactor domestic sewage treatment equipment. Background technique [0002] MBBR (Moving-Bed Biofilm Reactor, MBBR moving bed biofilm reactor) is a new type of biofilm reactor, which is developed on the basis of fixed bed reactor, fluidized bed reactor and biofilter. Improved novel composite biofilm reactor. It overcomes the need for regular backwashing in fixed bed reactors, the need to fluidize the carrier in fluidized bed reactors, and the complex operations of cleaning filter materials and replacing aerators in submerged biofilters, and retains the traditional biofilm It has the characteristics of anti-shock load, less sludge output and long sludge age. Compared with the activated sludge method, due to the longer sludge age, more nitrifying bacteria can be maintained, and it has a better denitrific...
