Working process of the present utility model is: water inlet enters reactor uniformly by water distribution system, and the mud mixture that water inlet and inner circulating tube descend makes internal flow become the fast rotational suspended state through spiral water distributor secondary distribution, and the organism processing efficiency improves.Liquid is retained in the reactor most of bacterial classification by triphase separator, and biogas and part of contaminated water, bacterial classification enter steam separator by the biogas upcast, and biogas is discharged from the top, and sewage and part bacterial classification then enter into reactor bottom by downtake.The part effluent recycling is to reactor bottom simultaneously, and the part water outlet makes effusive bacterial classification come back to anaerobic reactor through separator for mud and water, and sewage then enters the next stage treatment process.Make under the upflow velocity of high water and gas into that water and granule sludge keep good admixture, system can reach higher load.The maximum characteristics of this reactor are that duty ratio is higher, and floor space is little, and energy consumption is low, and is stable.
The maximum characteristics of this reactor are that duty ratio is higher, and floor space is little, and energy consumption is low, and is stable.The volumetric loading of reactor is not 5～8kg/m before improving
3.d, improving afterwards, volumetric loading can reach 30～40kg/m
3.d; The upper reaches speed that outer circulation need provide before not improving is 8～12m/h; Outer circulation only need provide the upper reaches speed of 3～5m/h after improving, and energy consumption reduces by 30%～40%; Biogas output in the unit volume can reach original 3～5 times.But in the utility model reactor granules mud prolonged preservation reactor, prevent that bacterial classification runs off, bacterial classification can be sold simultaneously.
The beneficial effects of the utility model are:
1, by internal recycle, outer circulation, sewage backflow, the bacterial classification multiple mode that refluxes, muddy water good mixing effect, processing efficiency height.
2, adopt novel secondary spiral water distributor, help carbonated drink separation, prevent the obstruction of water distribution pipe.
3, adopt separator for mud and water to prevent that as far as possible bacterial classification runs off, and has optimized effluent quality simultaneously.
4, triphase separator 14 is different with the water yield, water quality with 15, and structure changes to some extent.
5, traditional anaerobic reactor does not add the mud return-flow system, and the utilization of sewage backflow system is also insufficient, except causing bacterial classification loss seriously.Relatively harmonic(-)mean is about 70% for the clearance of pollutent, and at many load anaerobic reactor system's adding mud return-flow systems and sewage external circulating system, the clearance of system can fully keep anaerobic grain sludge, and move more stable on average more than 85%.
