Description
Technical field
The utility model belongs to sewage treatment area, is specifically related to a kind of domestication by low temperature device of denitrification flora.
Background technology
Nitrogen phosphorus discharge excessive in sewage can aggravate the eutrophication of receiving water body, the reduction of dissolved oxygen; The growth of some algae can discharge toxin, increases the weight of water quality deterioration, causes the mortality of aqueous bio.In water body, the biological removal of total nitrogen mainly relies on two large class denitrification microorganisms to be achieved.In nitrifying process, primarily of ammonia nitrogen being converted to the ammonia oxidizing bacteria of nitrite nitrogen and nitrite nitrogen being converted into the nitrite nitrogen oxidizing bacteria of nitre nitrogen; Nitric nitrogen is then converted into nitrite nitrogen by denitrifying bacterium, and then is transformed into gaseous nitrogen.Growth and breeding speed and activity all can significantly reduce major part denitrifying bacteria under cryogenic, the effect of nitrification and denitrification effect also can run down, so need to tame the resistance to elevated temperatures of denitrifying bacterium, existing domesticating device forms primarily of stirring rake, aerating apparatus and refrigerating unit, although can play a role in the domestication process of denitrifying bacterium, but one-piece construction is comparatively loaded down with trivial details, various piece exists the larger temperature difference in reactor, cause domestication result unsatisfactory.
Utility model content
It is simple, easy to use that the utility model object is to provide a kind of structure, can effectively realize high-level efficiency, the high temperature acclimation device of comprehensive denitrification flora of lowering the temperature.
For realizing above-mentioned technical purpose, by the following technical solutions:
A kind of domestication by low temperature device of denitrification flora, comprise reactor, refrigeration plant, off-gas pump, cooling tube and coil pipe, wherein off-gas pump entrance and refrigeration plant are connected, to be exported and coil pipe is connected, coil pipe is arranged at reactor inner bottom part, coil pipe is provided with several aperture, cooling tube coils in reactor outer wall, and cooling tube top is provided with liquid outlet, bottom is provided with liquid inlet.
For making the utility model more be suitable for practicality, make further improvements below:
Also stirring rake is provided with in described reactor.
Described coil pipe is Stainless Steel Coil.
Described aperture spacing is between any two 2-5 times of hole diameter.
The beneficial effects of the utility model are: the utility model structure is simple, easy to use, by off-gas pump, the freezing air produced in refrigeration plant is sent into coil pipe, sprayed by the aperture that coil pipe is offered again, mix with the water in reactor uniformly, reach the object from internal cooling and aeration.Again by the cooling tube ecto-entad cooling that reactor outer wall is arranged, fully realize the comprehensive effect of cooling.
