Description
Technical field
It is used for livestock and poultry cultivation sewage disposal circulating biological selecting reactor the present invention relates to one kind, belongs to sewage disposal skill
Art field.
Background technology
With the propulsion of adjustment and the agriculture industrialization of China's structure of agricultural production, livestock culture industry obtains scale, intensive
Fast development, the pollution problem brought therefrom is also increasingly serious, and regional environmental quality is generated and had a strong impact on, subregion
The air in basin, the pollution level of surface water and groundwater are quite serious, and livestock culture organic matter of sewage concentration is high, water quality ripple
It is dynamic big, it has also become the one of the main reasons of China's rural pollution, not only environment is polluted, the health of people and animals is influenceed, jeopardizes
The life of people and animals, also has influence on the food security of the mankind.At present, processing livestock culture sewage method be by separation of solid and liquid,
Anaerobism, Aerobic Process for Treatment, such as Publication No. CN103449606A, a kind of entitled " resistance mud for livestock and poultry cultivation sewage disposal
Formula biological anaerobic reactor ", carries out anaerobism, Aerobic Process for Treatment, improves system sludge concentration and activity, with high concentration being maintained micro-
The characteristics of biology, stable processing, but livestock culture sewage sludge in processing procedure needs backflow, nitrification liquid to be also required to backflow,
Cause that operating process is complicated, cost of sewage disposal is high, therefore, work out one kind in sewage disposal process sludge and nitrification liquid without
The method for needing backflow, cost low, simple to operate, has great importance to livestock culture sewage disposal now.
The content of the invention
The technical problems to be solved by the invention：For the above method processing livestock and poultry cultivation sewage in sludge need backflow,
Nitrification liquid needs backflow, causes the drawbacks of operating process is complicated, operating cost is high to be used for livestock and poultry cultivation sewage disposal there is provided one kind
Circulating biological selecting reactor, this method processing livestock and poultry cultivation sewage sludge and nitrification liquid are without backflow, and three-phase is in not Tongfang
To being separated, make three phase separation more thorough.
In order to solve the above technical problems, the present invention uses technical scheme as described below：One kind is used for livestock and poultry cultivation sewage
Processing cycle formula bioselection reactor, is mainly made up of, livestock and poultry exhaust outlet, reactor body, water inlet, sump and delivery port
The area of anaerobism one that aquaculture wastewater is entered in reactor body by water inlet, sewage is uniformly distributed by water distributing plate, and sludge is with dirt
A stream part waterborne falls into column plate bottom from swash plate, realizes mud-water separation, the sludge of incremental portion overflows across overflow outside plate by center
The sewage that passage is directly fallen into after sump, anaerobism overflows across overflow inner panel and accesses the area of bioselection one by pipeline, and biology is selected
After selecting, sewage enters the area of biology aerobic one from the area bottom of bioselection one, is aerated 2h~3h, and water overflows across overflow inner panel and drawn through pipeline
Enter the area of anaerobism two and carry out denitrification, excess sludge part overflows across overflow outside plate and fallen into sump, and nitrification liquid overflows across overflow inner panel
The area of bioselection two is introduced by pipeline, biological adaptation Sexual behavior mode is carried out, sewage enters biology aerobic from the area bottom of bioselection two
2nd area, are aerated 1h~2h, and some residual sludge overflows across overflow outside plate and fallen into sump, and water overflows across overflow inner panel and introduced through pipeline
The area of anaerobism three carries out denitrification, circulates successively, is carried out by the area of bioselection three, the area of biology aerobic three at selectivity organism aeration
Reason, the gas produced by anaerobism is discharged by exhaust outlet, and sewage is after the processing of the area of biology aerobic three is completed through water fender by delivery port
Sludge in outflow, sump is discharged through dredge pump；The described area of biology aerobic one, the area of biology aerobic two and the area of biology aerobic three
Aerating gas be through air inlet pipe by air inlet layering be filled with.
A diameter of 10~the 15m of described reactor body, a diameter of 2~3m of central passage.
The described area of anaerobism one, the area of anaerobism two, the area of anaerobism three and the area of biology aerobic one, the area of biology aerobic two, biology aerobic
Space between 3rd area is 0.5m.
The described area of anaerobism one is provided with water distributing plate, the area of anaerobism one, the area of anaerobism two, the area of anaerobism three, biology aerobic
One area and the area of biology aerobic two are equipped with overflow outside plate and overflow inner panel, and the area of biology aerobic three is provided only with outside overflow
Plate.
Described overflow outside plate is highly 2.5m, and overflow inner panel is highly 2.0m.
The application process of the present invention：The area of anaerobism one that livestock and poultry cultivation sewage is entered in reactor body by water inlet, sewage
It is uniformly distributed by water distributing plate, sludge from swash plate falls into column plate bottom with the upper part of sewage, realizes mud-water separation, increases
Partial sludge overflows across the sewage that overflow outside plate directly fallen into after sump, anaerobism by central passage and overflows across overflow inner panel by pipeline
The area of bioselection one is accessed, after biology is selected, sewage enters the area of biology aerobic one from the area bottom of bioselection one, is aerated 2h
~3h, water overflows across overflow inner panel and introduces the area of anaerobism two progress denitrification through pipeline, and excess sludge part overflows across overflow outside plate and fallen into
In sump, nitrification liquid overflows across overflow inner panel and introduces bioselection two area by pipeline, carries out biological adaptation Sexual behavior mode, and sewage is from life
Thing selects two area bottoms to enter the area of biology aerobic two, is aerated 1h~2h, and some residual sludge overflows across overflow outside plate and falls into sump
In, water overflows across overflow inner panel and introduces the area of anaerobism three progress denitrification through pipeline, circulates successively, by the area of bioselection three, biology
Aerobic 3rd area carries out selectivity organism Air Exposure, and the gas produced by anaerobism is discharged by exhaust outlet, and sewage is in biology aerobic three
Area's processing is flowed out after completing through water fender by delivery port, and the sludge in sump is discharged through dredge pump.
The present invention is compared with other method, and advantageous effects are：
(1) sludge increased directly falls into bottom, without blowdown；
(2) nitrification liquid of aerobic zone discharge is directly entered anaerobic zone and carries out denitrification, without nitrification liquid backflow；
(3) sludge anaerobism, aerobic repeatedly, reaches the purpose of dephosphorization；
(4) gas, solid, liquid are discharged in different directions, make three phase separation more thorough；
(5) excess sludge is directly fallen into sump.
