Description
Technical field
This utility model relates to sewage treatment area, is specifically related to a kind of negative-pressure guide sewage treatment unit.
Background technology
The Aeration tank of conventional activated sludge process can only carry out Aerobic biological process, the mud flowed in sedimentation tank increases gradually, manually to extract reservation out standby, and aerobic zone (Aeration tank) and anaerobic zone (sedimentation tank) are separated, mud can not automatic back flow, more can not aerobic with anaerobic zone Automatic Cycle (denitrogenation dephosphorizing).
Summary of the invention
Goal of the invention: this utility model is in order that overcome drawbacks described above, it is provided that a kind of negative-pressure guide sewage treatment unit.
nullTechnical scheme: the technical solution of the utility model is a kind of negative-pressure guide sewage treatment unit，Including reaction tank，It is internally provided with negative-pressure guide plate group at reaction tank，Described negative-pressure guide plate group is divided into reaction tank aeration zone and decanting zone，Aeration zone is connected through negative-pressure guide plate group by cross over pipe with decanting zone，It is provided with aeration head near the bottom of negative-pressure guide plate group in aeration zone，It is provided with slush pump in the bottom of decanting zone，It is provided with overflow outlet on the tail top of decanting zone，Described negative-pressure guide plate group includes three pieces of deflectors，Both sides are aeration zone end deflector I and decanting zone end deflector III，Centre is deflector II，Space is had bottom the lower end of described aeration zone end deflector I and decanting zone end deflector III and reaction tank，The upper end lower than aeration zone end deflector I and decanting zone end deflector III, the upper end of described deflector II，Aeration zone end deflector I、Space is had in the middle of deflector II and decanting zone end deflector III.
Preferably, the lower end of described aeration zone end deflector I and decanting zone end deflector III is from the 1/2-1/5 that the distance at the bottom of reaction tank is reaction tank height, the upper end of described aeration zone end deflector I and decanting zone end deflector III is higher than overflow outlet, and the upper end of described deflector II is lower than overflow outlet.
Preferably, the lower end of described aeration zone end deflector I is from the distance at the bottom of reaction tank is reaction tank height 1/3, the lower end of described decanting zone end deflector III is from the distance at the bottom of reaction tank is reaction tank height 1/4, and the upper end of described deflector II lower than the distance of overflow outlet is: overflow outlet is apart from the bottom of reaction tank the 1/3 of height.
" negative-pressure guide " is on the basis of biological activated sludge treatment technology, the return-flow system of mud has been improved, utilize aeration ascending air to drive the negative pressure that the lower current produced are formed between deflector crack to allow mud by decanting zone automatic back flow, instead of traditional machinery backflow.Process pond is separated into aerobic zone (aeration zone) and anaerobic zone (sludge settling, shunting zone of removing contamination) by deflector simultaneously, sewage and mud under the drive of current at the interval iterative cycles automatically of aerobic zone and anaerobism, to pass by that each operation scattered such as aerobic (aeration), anaerobism circulation, clear water mud separate, sludge reflux concentrates on one and processes in pond and be automatically performed, therefore can degrade efficiently COD and the pollutant such as ammonia nitrogen, phosphorus.Sewage disposal energy investment reduction, minimizing place is made to take, improve treatment effeciency, and be easily managed.
Beneficial effect: negative-pressure guide technology with equipment compared with existing activated sludge process technology, have take up an area less, reduced investment, be easily managed, personnel are few, operating cost is low, the feature of high treating effect and treating capacity wide accommodation.
Negative-pressure guide technology makes aeration zone and decanting zone be integrated, and eliminates second pond, saves occupation of land；Save occupation of land, save structures and the input of equipment, naturally also save investment.
Negative-pressure guide device instead of many electromechanical equipments with fixing Steel structure equipment, such as mud scraper, sludge reflux pump (oxidation ditch, conventional activated sludge process), water decanter (SBR method) etc., almost without fault in running after negative-pressure guide rigging up and debugging success, without maintenance.Thus bring several benefit: simplify handling process, also just simplify control and management, decrease operation, management and attendant, the saving of personnel i.e. the saving of running cost；Eliminate electromechanical equipment simultaneously and also just save energy consumption and the maintenance cost of these equipment, thus saving running cost.
It is divided into aerobic zone (aeration zone) and anaerobic zone (decanting zone) owing to processing pond, activated sludge is being brought to anaerobic zone from aerobic zone with current, aerobic zone is returned to by the backflow zone of action of negative-pressure guide plate again after sedimentation, so repeated multiple times anaerobic-aerobic circulation, nitrated, nitrococcus-denitrifying bacterium is conducive to ammonia nitrogen to be decomposed into nitrogen and is discharged in air, thus both having reached to remove the purpose of ammonia nitrogen, expenses increasing time or space again not more.Mud, in aerobic and anoxic zone Automatic Cycle, effectively suppresses hyphomycetic growth, and process system does not have sludge bulking.Therefore, using the sanitary sewage disposal engineering that negative-pressure guide technology carries out, BOD, the clearance of COD is up to more than 90%, and ammonia nitrogen reaches more than 95%, COD, BOD of effluent quality5, ammonia nitrogen, the leading indicator such as SS, TP namely reach GB18918-2002 one-level A mark.
