It is respectively equipped with fixing filler, combined stuffing and floating stuffing in oxygen section, be provided with aerator in the bottom of anoxia section and aerobic section.
Aerobic section can be a uncovered container.Floating stuffing can make violent unordered fortune under the promotion of bottom aerator
Dynamic, so that every nook and cranny is in aerobic state, be conducive to the carrying out of biochemical treatment.
Further, it is provided between described anaerobism section and anoxia section and detest scarce passage and detest scarce return flow line.Detest lacked water lead to
Road is the passage that anaerobism section flows to anoxia section；Correspondingly, detest the passage that scarce return flow line is that anoxia section is back to anaerobism section.Its
In, passage may each be an opening.
Further, it is provided between described anoxia section and aerobic section and lack passage and become reconciled scarce return flow line.Lacked well water to lead to
Road is the passage that anoxia section flows to aerobic section；Correspondingly, lacking well return flow line is the passage that aerobic section is back to anoxia section.Its
In, passage may each be an opening.
Further, in described anaerobism section, several deflection plates are installed, fixing uniform filling is distributed between deflection plate.
This utility model can also connect offer nitrification settler, including sedimentation tank, described sedimentation tank after aerobic section
Inside it is divided into contraminated zone and settling zone, is provided with aerating system in the bottom of sedimentation tank, be provided with nitrifying sludge in the lower section of aerating system
Return duct and air stripping system.
Fill inclined plate packing in the settling zone of sedimentation tank, carry out biochemical treatment further, and precipitation carries through aerating system
For oxygen nitrification after mud through air stripping system flowback to anaerobism section be anaerobe provide carbon source.
Know-why of the present utility model：After pretreatment, Small Town Wastewater is through entering integrated A AO（Anaerobic-anoxic-good
Oxygen）Biochemical device anaerobism section, arranges multiple little lattice in anaerobism section, each little lattice is provided with deflection plate, is filled with fixation between deflection plate
Filler, sewage advances through the upper and lower baffling of deflection plate after entering anaerobism section, carries out a point reaction by every lattice one by one, has good water
Power fluidised form, in water inlet, hardly degraded organic substance here is hydrolyzed acidifying, improves the biodegradability of sewage；The sewage of anaerobism section tail end
Enter anoxia section in anaerobism section with scarce section section junction one end, it is anti-that the other end then carries out anaerobic phosphorus release for backflow anoxia section mixed liquor
That answers detests scarce return flow line；Sewage enters filling suspension in aerobic section, aerobic section through anoxia section and aerobic section intersection one end and fills out
Material, forms biological floating bed, because suspended biological flotation bed is under the promotion of at the bottom of pond aerator, is thoroughly mixed, touches with sewage
Hit, shear, make the bubble that aerator transmits more tiny, improve coefficient of oxygen utilization, complete the oxidation of organic pollution, ammonia nitrogen
The reaction such as nitrification and suction phosphorus, the other end is then the well scarce return flow line that aerobic section nitrification liquid is back to anoxia section, enters anoxia section,
It is provided with combined stuffing, the nitrification liquid here of backflow carries out denitrification denitrogenation, and its water outlet part is back to anaerobism in anoxia section
Section, substantially reduces the harmful effect that nitrate nitrogen reacts to anaerobic phosphorus release；Enter the sewage of aerobic section, in the effect of floating stuffing
Under, fast breeding, accomplish biological multiplication；Sewage is downward through outlet row after the process of anaerobism section → anoxia section → aerobic section
Procedure.
Aerating system is laid in sedimentation tank central authorities near bottom, by micro supply, accelerates the mud nitrification sinking to the bottom；Conflux
Nitrification mud liquid to bottom of device central authorities is back to preamble by the air stripping system being arranged on below aerator by nitrifying mud liquid
Technique；Source of the gas is respectively aerating system supply and air stripping system supply, individually controls.Air stripping system shares one with aerating system
Feeder, avoids the need for installing power-equipment in the bottom of sedimentation tank；Nitrifying sludge can be flowed back by siphonage and provide
Carbon source, can save power.
The beneficial effects of the utility model：1. one AAO biochemical treatment apparatus form one by unit-modularized for civil engineering structure
The form of body equipment, reduces on-site construction time, shortens construction period.2. anaerobism section baffling hydrolysis acidification, improve sewage
Biodegradability simultaneously carries out anaerobic phosphorus release reaction with backflow anoxia section mixed liquor；Anoxia section fills combined stuffing denitrification denitrogenation, good
Oxygen section filling floating stuffing can be rapidly completed the oxidation of organic pollution, the nitrification of ammonia nitrogen and inhale the reaction such as phosphorus, accomplish to give birth to simultaneously
Thing doubles, and controls its dissolved oxygen can save energy consumption in a large number.3. AAO process unit loads different fillers, sewage treatment capacity respectively
Multiplication, aerobic section（O section）Floating stuffing by comprehensive to sewage and mud contact, collision and shearing, pond holds is fully used, work
Skill takes up an area province, and resistance to impact is strong, stable performance, safeguards simple.4. outlet effect is good, can reach《Urban wastewater treatment firm pollutes
