Description
Technical field
The utility model relates to a kind of high-efficiency and energy-saving type film biological nitration reactor.
Background technology
Along with the development of industrial and agricultural production and the raising of living standards of the people, the quantity discharged of nitrogenous compound sharply increases, and the source of polluted by nitrogen is many, and quantity discharged is big.Except that sanitary sewage and animal excrements, trade effluent (as trade effluents such as iron and steel, oil refining, chemical fertilizer, inorganic chemical industry, iron alloy, glass manufacturing, meat processing and fodder production) also contains a large amount of nitrogen, wherein ammonia nitrogen is the main form of nitrogen in the water surrounding, is the important pollution substance that causes body eutrophication and environmental pollution.How to control the key subjects that ammonia nitrogen waste water pollutes have been become current environmentalist and faced cost-effectively.
The method that is applied to denitrogenation of waste water at present has physics method, chemical method and biological process.From economy and treatment effect, biological process has certain advantage, uses wider at home and abroad.The cardinal principle of biological process is to utilize Nitrite bacteria that the ammonia nitrogen in the waste water is oxidized to nitric nitrogen (nitrite nitrogen) earlier, utilizes denitrifying bacterium that nitric nitrogen (nitrite nitrogen) is changed into nitrogen again.Because the nitrobacteria poor growth, too high ammonia nitrogen concentration then can suppress the activity of nitrobacteria, and bio-denitrification technology also has been subjected to serious challenge.Research and development can efficiently be held and be stayed thalline and can alleviate the nitrator that ammonia nitrogen suppresses, and has important practical significance for the advantage of further performance denitride technology.
Research to membrane bioreactor in the last few years constantly heats up, trace it to its cause, mainly be: 1. membrane bioreactor has good mud-water separation effect, can realize holding back fully to thalline, make thalline (mud) residence time not be subjected to the restriction of hydraulic detention time, these characteristics are fit to thalli growth nitrator slowly very much; 2. because membrane module to the holding back fully of thalline, can keep higher cell concentration in the reactor, volumetric efficiency and job stability strengthen greatly; 3. the cost of membrane module constantly reduces, and performance is continued to optimize, and membrane module possibility of widespread use in wastewater treatment increases gradually.But, the very easily contaminated and influence infiltration water outlet of membrane module, delaying that film pollutes and reduce because of overcoming the energy that membrane resistance consumes is the emphasis that current membrane bioreactor is studied.
Summary of the invention
The purpose of this utility model provides a kind of high-efficiency and energy-saving type film biological nitration reactor.
It has the nitrator body, in the nitrator body, be provided with membrane separation assemblies, be provided with water inlet pipe, micropore aeration pipe in nitrator body bottom, water inlet pipe is provided with magnetic valve, the membrane separation assemblies bottom links to each other with header, header links to each other with water tank, and the water tank upper end is provided with height-adjustable outlet, and magnetic valve links to each other with fluid level controller.
The utility model has very high specific surface area owing to substitute the membrane separation assemblies of settling tank, membrane separation assemblies shared volume in bio-reactor is very little, in addition because the membrane sepn effect can make reactor keep higher sludge concentration, thereby improve the volumetric loading of reactor, therefore can save the volume that reduces reactor, realize the small-sized integrated of treatment facility easily.Because this film biological nitration reactor film utilizes liquid level difference infiltration water outlet, need not extra energy consumption, energy-saving effect is obvious.Can realize automatization control by The real time measure, make the operation of reactor and treatment effect reach optimum flow to the reactor operation.

Embodiment
Energy-saving film biological nitration reactor has the nitrator body, in the nitrator body, be provided with membrane separation assemblies 4, be provided with water inlet pipe 1, micropore aeration pipe 5 in nitrator body bottom, water inlet pipe 1 is provided with magnetic valve 2, membrane separation assemblies 4 bottoms link to each other with header, header links to each other with water tank 6, and water tank 6 upper ends are provided with height-adjustable outlet 7, and magnetic valve 2 links to each other with fluid level controller 3.
Said membrane separation assemblies 4 adopts the one immersion, and promptly membrane separation assemblies is placed on the nitrator body interior, and the type of membrane module is flat folded membrane, and the membrane module surface-area of placing in every cubic metre the reactor is 10～200m
2Membrane module unit series connection is earlier in a row arranged assemblies water outlet in parallel then, and the distance of connecting between the single membrane module in a row is 3～5cm, and the array pitch of arranging the assembly parallel connection is 30～50cm more.The distance that it is arranged in micropore aeration pipe 5 tops is 10～30cm.The waterhead of nitrator body and water tank 6 is 0.1～1m.
The utility model has been realized the efficient operation of nitrator by staying to the active reinforcement of nitrobacteria with to holding of nitrobacteria, by the appropriate design to reactor configuration, realizes that the energy consumption of nitrator reduces.Evidence, membrane bioreactor has high volumetric efficiency and good treatment effect in ammonia nitrogen waste water is handled.In pH7.5～8.5, under the operational condition that temperature is 25～30 ℃, the highest influent ammonium concentration that reactor can bear reaches 120mmo1L
-1Keeping higher influent ammonium concentration (60mmolL
-1) situation under, reactor can reach 8kgm to the stable volume transformation efficiency of ammonia nitrogen
-3D
-1, ammonia nitrogen removal frank remains on more than 90.00%.Cell concentration (MLVSS) reaches 20g.L in the reactor
-1More than.Detect less than suspended matter in the reactor water outlet, water quality is better.Reactor need not to discharge thalline, can realize the zero release of thalline (mud).
