The utility model relates to an autotrophic denitrification device, which is suitable for the treatment of nitrogen-containing wastewater, particularly for the treatment process of organic wastewater containing high nitrogen content so as to transform nitrate nitrogen and nitrite nitrogen into gaseous nitrogen and enable the ammonia nitrogen in water to discharge up to the standards. The device comprises a box body and a bracket body; the box body is arranged in the lower bracket of the bracket body; small holes are formed on the six surfaces of the box body; a movable cover plate is arranged on the top surface of the box body; the autotrophic denitrification agent filled in the box body is a type of porous sintered solid matter, of which the principal components are sulfur, calcium carbonate and the like; and the autotrophic denitrification agent is put in an anaerobic tank, and enables autotrophic denitrifying bacteria to perform autotrophic denitrification and reduce the nitrate nitrogen into nitrogen effectively under the anoxic condition. The device is suitable for the treatment of nitrogen-containing wastewater, particularly for the treatment process of organic wastewater containing high nitrogen content and low carbon-nitrogen content, such as liquid dung, swill, garbage percolate and the like.
Description
Technical field
The utility model relates to technical field of sewage, is specifically related to a kind of device of autotrophic denitrification process.
Background technology
The method of finishing denitrification process has a lot, and is many at present based on microbial process.Because nitrifier is the autotrophy aerobic microbiological, and denitrifying bacteria mostly is the heterotrophism anaerobion, so in sewage disposal, better realize denitrifying process by control dissolved oxygen and adjusting carbon source usually.Microbial growth needs energy balance, in theory when carbon ratio nitrogen greater than 5-10: 1 can realize the denitrification process, and for the organic sewage of high density, example: liquid dung, swill, percolate etc., all exist the lower problem of carbon-nitrogen ratio, in order to finish the necessary additional carbon of denitrification process, as methyl alcohol, glucose, flour etc.Like this, both increase the cost of sewage work, increased unnecessary pollution load again.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of autotrophic denitrification device that nitric nitrogen and nitrite nitrogen are converted into the transformation efficiency of gaseous nitrogen that improves is provided.
The purpose of this utility model is achieved through the following technical solutions.
A kind of autotrophic denitrification device is installed in anoxic pond or the anaerobic pond, and the autotrophic denitrification device comprises a casing and a stake body; Six faces of described casing are covered with aperture, and the aperture of tank floor aperture is less than the aperture of other five apertures.The end face of casing is a removable cover, and removable cover is fixed on the casing by latch.Described stake body is made up of upper bracket and lower bracket, and casing is contained in the lower bracket of stake body.The autotrophic denitrification agent of mainly being made up of sulphur, lime carbonate is housed in casing, and the autotrophic denitrification agent is porous sintered solid substance.
Autotrophic denitrification device of the present utility model, pending waste water passes through in from then on installing, and can improve the transformation efficiency (being denitrification) that nitric nitrogen and nitrite nitrogen are converted into gaseous nitrogen, reduces the nitrogen content in the water outlet, makes the water outlet qualified discharge.The utility model is made simple, and is convenient and practical, only just can realize the purpose of disposing of sewage with the starting material of utmost point low cost.The utility model also has is convenient to the advantage safeguarding, be convenient to change.

Fig. 2 is the side-looking structural representation of autotrophic denitrification device among Fig. 1;
Fig. 3 hangs schematic top plan view on anoxic pond or anaerobic pond for the utility model.
Among the figure: 1, casing, 2, lower bracket, 3, upper bracket, 4, removable cover, 5, the device front side, 6, the device rear side, 7, cross-arm.
Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, the autotrophic denitrification device, its main body is a casing 1, is installed in the anoxic pond, casing 1 is packed in the lower bracket 2 of the stake body be made up of upper bracket 3 and lower bracket 2.The autotrophic denitrification agent is housed in the casing 1, and casing 1 is formed by the polythene material welding production, and casing 1 six faces are covered with aperture, and the aperture of casing 1 bottom surface is 4-6mm, and the aperture with end face is 9-11mm all around.Casing 1 end face is an active cover plate 4, and removable cover 4 is for the usefulness of checking, add or change the autotrophic denitrification agent.Removable cover 4 usefulness latches are fixed on the casing 1.The autotrophic denitrification agent of dress is the porous sintered solid substance of a kind of 20-60mm of being of a size of in the casing 1, and its aperture is at 1-8mm.That solid substance is shaped as is square, circular or its allothimorph, its main component is sulphur, lime carbonate etc., and its action principle is to utilize element sulphur as electron donor, under anoxic or anaerobic situation, make denitrifying bacteria carry out the autotrophic denitrification effect, nitric nitrogen is reduced to nitrogen effectively.Owing to need to consume alkali in the nitrated process of autotrophy, thus lime carbonate as a kind of not only economical rationality but also effectively batching together add in the autotrophic denitrification device.
Waste water from the device front side 5 aperture enter casing 1, with in the casing 1 the autotrophic denitrification agent contact.The autotrophic denitrification agent is the porous sinter, and surface-area is bigger, so on the one hand can be a large amount of electronics is provided, make denitrifying bacteria carry out autotrophic denitrification, on the other hand, can provide the home for procreation, the activity of autotrophic denitrification bacterium.Because the autotrophic denitrification device has satisfied the autotrophic denitrification bacterium and has carried out denitrifying condition, so improved the denitrification rate.Sewage is 5 inflows from autotrophic denitrification device front side, by the autotrophic denitrification agent, flow out from device rear side 6, nitric nitrogen and nitrite nitrogen in water outlet this moment have changed into nitrogen, so reduced the nitrogen content in the water outlet, finished denitrification process, reached the purpose of sewage water denitrification.
Be installed on the narrow 50-100mm of casing 1 total-width ratio anoxic pond in the anoxic pond, the aspect ratio liquid level hangs down 30-50mm, and length is 300-800mm, and thickness is 500-1500mm.Quantity at casing described in the anoxic pond 1 is 1-16.Around the casing 1 and the aperture that is covered with on the cover plate 4 at top, contact with the autotrophic denitrification agent and pass through in order to water; The aperture that the case base fabric is full also makes a part of water pass through, the unlikely bottom that accumulates in casing 1 of sewage.
Autotrophic denitrification agent in the casing 1, be square or circular and other shape of a kind of 15-20mm porous sintered solid substance.Casing is put in the lower bracket 2 that is welded by angle steel, and stake body is made up of upper bracket 3 and lower bracket 2, and it all is welded with 25-75mm or bigger angle steel, and does necessary rotproofing.Upper bracket 3 is hung (see figure 3) on two cross-arms 7 on the anoxic pond, and lower bracket 2 is hung on the extension leg of upper bracket 3 bottoms, thereby has realized the connection of top and the bottom supports, and stake body is suspended among anoxic pond or the anaerobic pond.
The utility model is applicable to the processing of nitrogenous effluent, is specially adapted to the organic waste water that nitrogen content is higher, carbon-nitrogen ratio is lower, as liquid dung, and the treating processes of swill, percolate etc.
