Abstract
A multi-biomass bioreactor features that anaerobic sludge region, sand and soft filler of fibre bundles are arranged in the equipment to increase the specific surface area of inert medium, collect anaerobic microbe, speeding up the degradation of organic waste water and raise effect.
Description
The present invention relates to device, especially multi-biomass bioreactor that a kind of organic waste water anaerobic biological is handled.
At present, the anaerobic biological treatment process of known organic waste water is to utilize the anaerobion degradation of organic substances, makes it innoxious.According to this treatment process, mainly contain anaerobic sludge method and anaerobe embrane method.The anaerobic sludge method is with water pump waste water to be imported from reactor bottom, makes mud and microorganism be suspension, flow state and produces cohesion, absorption and Decomposition, removes organism.The anaerobe embrane method then is that the surface that makes anaerobion be attached to some carrier is membranaceous, and the organism of picked-up in the waste water done nutrition and in addition metabolism, thereby makes purification of waste water.The reactor of these methods mainly contains digester, anaerobic filter, anaerobic fluidized bed etc.The reactor pattern that anaerobic biological is handled is single, and the microorganism total amount of unit waste water contact is few, inefficiency, and adopt anaerobic sludge to reflux to increase the method for biomass, increase investment and expense again, and reduced processing efficiency.
The bio-reactor that the purpose of this invention is to provide a kind of multi-biomass is to improve treatment effect.
The object of the present invention is achieved like this: in a device, be provided with anaerobic sludge zone, sand grains, fibrous bundle soft-filler etc.After waste water enters this device, rush at anaerobic sludge zone, make anaerobic sludge be in suspension, flow state, with the waste water thorough mixing and react, waste water passes the porous supporting plate, contact with sand grains, and make sand grains be fluidized state, and reacting with the fibrous bundle soft-filler again, the anaerobion of set growth fully contacts with waste water on these two kinds of materials, and react, be purified for waste water.
Owing to adopt such scheme, concentrate the microbial film of a large amount of anaerobic sludges and set growth in this device, and specific surface area is big, the unit's of making waste water is big with the microorganism amount of contact, fast reaction speed.This apparatus structure is simple, wide adaptability.
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is cross section structure figure of the present invention (1: 20).
Fig. 2 is vertical section structure figure of the present invention (1: 20).
Among the figure 1, shell 2, water inlet tap 3, water inlet 4, water inlet pipe 5, common brick masonry 6, water outlet 7, anaerobic sludge zone 8, porous supporting plate 9, sand grains 10, supporting bar 11, fibrous bundle soft-filler 12, cross bar 13, water outlet 14, faucet 15, gas block panel 16, biogas storehouse
In Fig. 1 embodiment, shell (1) bottom is built by Steel Concrete by concrete, top, long 2m, and wide 1m, dark 4m, the bottom is domatic.Water inlet tap (2) links to each other with water inlet pipe (4), 0.4m * 0.1m, water outlet (6) leads directly to anaerobic sludge zone (7), porous supporting plate (8) is with concrete prefabricated one-tenth porous plate, the carrying particle diameter is the sand grains of 0.6～1mm, thickness is 0.2m, and fibrous bundle soft-filler (11) colligation is carried its weight by cross bar (12) on supporting bar (10).
Among Fig. 1 embodiment, waste water forms water inlet (3) and flows into water inlet tap (2), flow out at water outlet (6) by water inlet pipe (4), mix with the mud of anaerobic sludge zone (7), microorganism in the anaerobic sludge and waste water generation DeR, enter porous supporting plate (8) then, make sand grains (9) be in fluidized state, the microbial film of the surperficial set growth of sand grains (9) contacts with waste water, DeR takes place, waste water enters in the fibrous bundle soft-filler (11), and the microorganism that goes up the set growth with its surface contacts, and DeR takes place, form water outlet (13) then, the device that enters next same pattern continues to react with microorganism, and the device series connection of several same patterns is used, and makes microorganism at different device generation acidolysis reactions and produce biogas.This device series connection is many more, and microflora's classification is also many more, and dominant bacteria is obvious more, and degradation rate is high more.Moreover the series connection classification is many more, and the waterpower fluidised form approaches plug-flow more, and short flow phenomenon is few more, and hydraulics is good more.
In Fig. 1 embodiment, the theoretical specific surface area of sand grains (9) is 3000m
2/ m
3, fibrous bundle soft-filler (11) specific surface area is 2474m
2/ m
3, spacing is 0.06m in length and breadth, and length is 0.12m, and the weight in each device is 40kg.
In an embodiment, adopt totally 60 in pattern device of the present invention (not comprising anoxic and aerobic treating processes), day processing 2000 T organic waste waters, the treatment time is 4.3h.Through this anaerobic biological treating processes, obtained the good treatment effect.
Claims (3)
1, a kind of multi-biomass bioreactor, constitute by shell (1), water inlet pipe (4), porous supporting plate (8), cross bar (12), it is characterized in that water inlet pipe (4) leads to anaerobic sludge zone (7), and sand grains (9) and fibrous bundle soft-filler (11) are arranged in device.
2, multi-biomass bioreactor according to claim 1 is characterized in that water inlet pipe (4) connects anaerobic sludge zone (7).
3, multi-biomass bioreactor according to claim 1 is characterized in that anaerobic sludge zone (7), sand grains (9), fibrous bundle soft-filler (11) are in same device.
