ABR厌氧反应器(国外英文资料) Anaerobic processing Anaerobic treatment system is the core part of livestock and poultry manure wastewater treatment engineering, the project for the anaerobic treatment system adopted by the ABR + AF (i.e., add in ABR reactor combination packing) combined process. The project is also equipped with a reflux pump to control the rising velocity of the anaerobic water, because the water flow is small and the water is discontinuous. The process has the following advantages: Refers to the standard Excellent point The reactor structure Simple structure, no moving parts and no mechanical mixing device, low cost, high volume utilization rate, difficult to block, low sludge bed expansion and can reduce the total height of the reactor Biomass characteristics No special requirements on the settling property of the organism, low sludge production rate, less quantity of sludge, high sludge age and sludge need to grow in the carrier surface, without subsequent spate separation tank The operation of the process Hydraulic retention time is short, can be in the form of intermittent operation, hydraulic and organic load impact resistant capability is strong, the poisonous and harmful substances in water with good tolerance, the back can be a very long time The basic principle of the reactor and its process structure Reactor used in a series of vertical installation baffle plate make the treated wastewater in the reactor flow up and down the baffle plate, with the aid of biogas generated from the reactor in the process of handling make the microbiological solid inside the reactor in the baffle plate formed by various indoor for expansion and sediment movement up and down, while the flow within the reactor at a slower speed for horizontal flow. Due to the effect of the sewage on the baffle, the flow of water around the baffle is increasing the total length of the flow in the reactor.In addition to the blocking of the baffle and the sedimentation of the sludge, the bi
