Description
Technical field
The present invention relates to sewage and the design field of fixed-end forces equipment.
Background technology
Anaerobic digestion refers under anaerobic utilize the process of microbial degradation and stable organic matter, anaerobic digestion process
In can produce biogas and excess sludge.Owing to anaerobically digested sludge yields poorly, energy resource consumption is little, it might even be possible to reclaim the energy, mesh
Front many application in organic solid waste and high concentrated organic wastewater process.But anaerobic digestion fluctuation of service, restraining factors is more, limit
Make it to promote.Ammonia nitrogen is one of main restraining factors of anaerobic digestion.The nitrogen substance such as protein, carbamide, through anaerobism
Digestion, nitrogen element therein can be converted to ammonia nitrogen.In changing food waste and the sewage such as waste water, animal wastes thereof and solid waste, nitrogenous
Amount height, during anaerobic digestion, easily produces ammonia nitrogen in high density, suppression digestion gas generation process.
Summary of the invention
Present invention aim at for problem above, it is provided that the anaerobic digestion of a kind of eliminated ammonia inhibition easy to use
Reactor.
The present invention includes anaerobic digestion reaction vessel, arranges gas film assembly at described anaerobic digestion reaction vessel inner chamber, described
Gas film assembly includes that membrane tube, described membrane tube are immersed under liquid level；Acid case is set outside described anaerobic digestion reaction vessel；Institute
The outfan stating acid case connects water inlet pipe, and the input at described acid case connects outlet pipe；Described water inlet pipe arranges circulation
Pump, water intaking valve；Described outlet pipe arranges outlet valve；The outfan of described water inlet pipe, outlet pipe input respectively with film
Pipe connects.
The material of the present invention film for making membrane tube is one or more in PP, PE, PVDF, PTFE or ePTFE
Mixture, or with the mixture of super-hydrophobic macromolecular compound.In membrane module by circulating pump pump into pH ＜ 2 dilute sulfuric acid,
Phosphoric acid,diluted, the mixture of one or more of dust technology.In use, membrane tube is immersed in below liquid level to the present invention, in acid case
Acid, through water inlet pipe, is pressurizeed by circulating pump, is pumped in membrane tube.Acid, during membrane module, absorbs outside membrane tube
Ammonia nitrogen, generates corresponding ammonium salt.After the absorption of a circulation, acid is flowed out from outlet pipe, returns in acid case.Acid absorbs saturated
After, gained ammonium salt can recycle.Valve, convenient maintenance are set on water inlet pipe and outlet pipe.
The invention has the beneficial effects as follows: the gas film assembly arranged in described anaerobic digestion reaction vessel, can effectively absorb
Ammonia nitrogen in sewage and solid waste, assimilation effect all can reach requirement in sewage of different nature and solid waste.Can according to sewage and
The amount of ammonia nitrogen in solid waste, the concentration of instant regulation absorbing liquid and soak time, it is ensured that in reactor, ammonia nitrogen concentration is at zone of reasonableness
In.After acid solution absorbs, the corresponding ammonium salt of generation can recycle.
Gas film assembly of the present invention is one or both mixture of tubular type, hollow fiber form.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
As it is shown in figure 1, the present invention includes anaerobic digestion reaction vessel 1, tubular type gaseous state is set at anaerobic digestion reaction vessel 1 inner chamber
Membrane module 2, tubular type gas film assembly 2 includes that membrane tube 2-1, membrane tube 2-1 are immersed under liquid level；Outside anaerobic digestion reaction vessel 1
Acid case 3 is set；Outfan at acid case 3 connects water inlet pipe 4, and the input at acid case 3 connects outlet pipe 5；Water inlet pipe 4 sets
Put circulating pump 6, water intaking valve 7；Outlet pipe 5 arranges outlet valve 8；The outfan of water inlet pipe 4, the input difference of outlet pipe 5
Connect with membrane tube 2-1.
Claims (2)
1. can eliminate an anaerobic digestion reaction vessel for ammonia inhibition, including anaerobic digestion reaction vessel, it is characterised in that: described
