With《Water prevention and cure of pollution action plan》Implementation, rural area water process market is classified as one of key project by government.
Whether market scale or policy guidance, rural area water treatment field are unprecedentedly strong.Because Chinese countryside is in topography and geomorphology, economy
Had differences in terms of level, ability to pay, effect requirements, the selection of rural sewage treatment technology path should cut the garment according to the figure.Thing
In reality, due to the particularity of Chinese countryside, the portion that builds, Chinese Ministry of Environmental Protection, Bureau of Water Resources etc. are lived in the choice of technology by correlation authorities of country
Not yet recommend particular technique route.
With reference to the actual conditions of Chinese countryside, the technology path of following rural sewage treatment should possess following feature：
1st, distributing treatment in situ；2nd, the advantage of single technology is made full use of, combination advantage technology is formed；3rd, one-time investment
It is small；4th, operating cost is low；Stable effluent quality when the 5th, running；6th, automatic operating can be realized.7th, facilities and equipment and proprietary technology
The long lifespan of product is as far as possible few to occur or do not occur the second investment expense.
The content of the invention
The present invention provides a kind of vertical integrated sewage-treatment plant, meets rural sewage treatment described in technical background
The technical solution adopted by the present invention is as follows to achieve the above object：
A kind of vertical integrated sewage-treatment plant, it is characterized in that logical including water pump, absorption mixing pit, anaerobic pond, backflow
Road, Aerobic Pond, circulation canal, rapid precipitation backflow pool, water leg, bag type filter device, water enter absorption through water pump and mixed
Pond is mixed herein with returned sludge, circulating water body, and water body enters anaerobic pond progress biological denitrification, biology and released at phosphorus after mixing
Reason, the water after processing flows into Aerobic Pond and carries out biological nitration, inhales phosphorus, and the water after Aerobic Pond processing enters circulation canal, and circulation is logical
Most of water flows into absorption mixing pit through return flow line in road, and fraction water enters rapid precipitation backflow pool, rapid precipitation backflow
Pond carries out mud-water separation to water, and primary water collects inflow bag type filter device through water leg, removes suspension in water.
Preferably, screen pack is installed, screen pack is made of rigid plastics, carried on screen pack at the pump intake
Needle-like crotch, screen pack mesh diameter is 5mm~8mm.
Preferably, high-efficiency composite biological filler is placed in the anaerobic pond, anaerobic pond bottom is installed with top and blocks protecting wire net, blocks
Protecting wire net bore dia is not more than high-efficiency composite biological filler diameter.
Preferably, aerator and high-efficiency composite biological filler are installed, wherein aerator is used in the Aerobic Pond
Nanometer aeration technology is made, and high-efficiency composite biological filler is in pie arrangement inside Aerobic Pond.
Preferably, the bag type filter device is from single bag type filter, and filtering accuracy is 0.8 μm~2 μm.
Compared with the prior art, beneficial effects of the present invention are as follows：
Installed at pump intake and needle-like crotch is carried on screen pack, screen pack, prevent line style debris from being wound into water pump
Water pump motor internal；The present invention organically combines biosystem, settling system and filtration system, merges in same reactor,
And according to fluid behaviour, the structure to sewage-treatment plant is optimized, and the height for realizing sewage disposal system is intensive, repeatedly
Circulation decontamination ensure that effluent characteristics.In addition, service life of the present invention is long, automatic operating can be realized, the second investment expense is few,
Delicate structure, practical, the rural area for being adapted to lack sewage treatment facility is used.
Referring to accompanying drawing:A kind of vertical integrated sewage-treatment plant, it is characterized in that including water pump 1, absorption mixing pit 2, detesting
Oxygen pond 4, return flow line 3, Aerobic Pond 6, circulation canal 5, rapid precipitation backflow pool 9, water leg 7, bag type filter device 8, water
Enter absorption mixing pit 2 through water pump 1 to mix herein with returned sludge, circulating water body, water body is given birth into anaerobic pond 4 after mixing
Thing denitrification, biology release phosphorus processing, and the water after processing flows into Aerobic Pond 6 and carries out biological nitration, inhales phosphorus, after the processing of Aerobic Pond 6
Water enters most of water in circulation canal 5, circulation canal 5 and, through return flow line 3, flows into absorption mixing pit 2, and fraction water enters fast
Speed precipitation backflow pool 9, rapid precipitation backflow pool 9 carries out mud-water separation to water, and primary water collects inflow pocket type mistake through water leg 7
Device 8 is filtered, suspension in water is removed.Screen pack 10 is installed in the water inlet of water pump 1, and screen pack 10 uses rigid plastics system
Into with needle-like crotch 11 on screen pack 10, the mesh diameter of screen pack 10 is 5mm~8mm.Placed in the anaerobic pond 4 efficient
Composite biological packing 401, the bottom of anaerobic pond 4 is installed with top and blocks protecting wire net 402, blocks the bore dia of protecting wire net 402 no more than high efficiency composition
The diameter of biologic packing material 401.Aerator 602 and high-efficiency composite biological filler 601 are installed in the Aerobic Pond 6, wherein being aerated
Device 602 is made of nanometer aeration technology, and high-efficiency composite biological filler 601 is in pie arrangement inside Aerobic Pond 6.The bag
Formula filter 8 is from single bag type filter, and filtering accuracy is 0.8 μm~2 μm.
