Abstract
The invention provides a folded plate anaerobic moving biofilm online sewage treatment system and relates to the technical field of sewage treatment systems. The folded plate anaerobic moving biofilm online sewage treatment system comprises a folded plate anaerobic reactor; the output end of the folded plate anaerobic reactor is connected with a moving bed biofilm reactor; and the first output end of the moving bed biofilm reactor is connected with a first water pipe. The invention designs an efficient energy-saving treatment method which is small in size, low in infrastructure expenditure and running expense, and more economical than a contact oxidation method and is an upgrade and an improvement or a substitute of a traditional activated sludge process, a fixed bed contact oxidation method and other treatment methods. The folded plate anaerobic moving biofilm online sewage treatment system is widely applied to newly building or upgrading and improving all the existing industrial and domestic sewage treatment systems and particularly greatly improving the system effluent quality and the phosphorus and nitrogen removal effect in the upgrading and improvement project on the premise that the improvement on the existing building is small, and the investment is reduced.
Description
Technical field
The present invention relates to the technical field of Sewage treatment systems.
Background technology
At present, the sewage of industry generation generally needs could externally discharge after treatment.There is following defective in existing industrial sewage treatment system: aerobic biofilter can not take full advantage of the pond to be held; The mechanical means problem can often appear in bio-disc system; The tradition submerged bacteria filter is difficult to make load to be evenly distributed on the surface of carrier, and needs back flushing, and washing the granule medium biological filter can not non-stop run; The power consumption of the similar technique of fluidized-bed mainly concentrates on the aeration, and the medium that common fluidized-bed adopts mostly is quartz sand, hard coal, gac, haydite and zeolite etc., and density is all greater than water, and the power that its complete fluidisation is consumed is large.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, provide a kind of efficient, economic, energy-conservation flap anaerobism to move the online Sewage treatment systems of microbial film.
The object of the present invention is achieved like this: the flap anaerobism moves the online Sewage treatment systems of microbial film, comprise the flap anaerobic reactor, the output terminal of flap anaerobic reactor connects MBBR, and first output terminal of MBBR connects the first water pipe.
The present invention adopts ABR flap anaerobic-aerobic MBBR to move the online Sewage treatment systems of biofilm bed, can realize that acidication, anaerobism put phosphorus (ABR), anoxic denitrogenation, aerobic suction phosphorus, the microbial film absorption degradation organism in the water of purifying waste water; Realize the reasonable removal efficient of organic pollutant by system's nitrification and denitrification.
The present invention is compared with prior art: 1. the mechanical means problem can often appear in bio-disc system, and organic and biophasic the contact is because there is not mechanical means aspect problem in the mixing generation of liquid phase among the MBBR;
2. traditional submerged bacteria filter is difficult to make load to be evenly distributed on the surface of carrier, and needs back flushing, and washing the granule medium biological filter can not non-stop run; And the continuous lifting of MBBR is exactly to make organic equally distributed process, and MBBR does not need back flushing;
3. the power consumption of the similar technique of fluidized-bed mainly concentrates on the aeration, and the medium that common fluidized-bed adopts mostly is quartz sand, hard coal, gac, haydite and zeolite etc., and density is all greater than water, and the power that its complete fluidisation is consumed is large; And the support density that MBBR adopts is little, and after carrying full microbial film, density is similar to 1, so the carrier power that mobile fluidisation consumes in reactor is little.
4.MBBR the carrier specific surface area that adopts is large, the biomass of its surface attachment is many, the food chain length, sludge concentration is high, and mud is long age, and system arranges flexibly, can be arranged to front end, rear end or synchronous nitration and denitrification, so that system's dephosphorization and denitrification effect is good, the sludge creation amount is little, the flow process of many application MBBR techniques is arranged even do not have sludge refluxing apparatus;
5.MBBR method is good than the treatment effect of activated sludge process, under the same load condition, gas, solid (matrix), liquid three-phase mass transfer transmission effect are good, and gas-water ratio can be saved greatly, so HRT can shorten;
In sum, design volume of the present invention is little, and capital cost is little, and working cost is low, than contact oxidation method economy, is the upgrading of the treatment processs such as traditional activated sludge process, fixed bed contact oxidation method or alternative energy-efficient treatment process.Be widely used in existing all industry and domestic sewage processing system is newly-built or upgrading, particularly in the project of upgrading and rebuilding, original structures changed less, under the prerequisite of reduced investment, increased substantially system's effluent quality and dephosphorization and denitrification effect.
The input terminus of flap anaerobic reactor of the present invention connects equalizing tank, and the input terminus of equalizing tank connects the grille well pond; Described equalizing tank connects aerating system by the first aerated conduit, and aerating system connects described MBBR by the second aerated conduit.MBBR is reasonably avoiding the dead angle under the layout because aeration and hydraulic hoist effect are distributed in the reactor suspending carrier widely, takes full advantage of the pond and holds.
For the water to MBBR is processed again, second output terminal of MBBR is connected with described equalizing tank.
In order further sewage to be processed, the 3rd output terminal of MBBR connects the subsurface infiltration ecosystem, and the output terminal of the subsurface infiltration ecosystem connects sterilization pool, and the output terminal of sterilization pool connects the second water pipe; Bottom in the described sterilization pool connects lower clapboard, top in the sterilization pool connects upper spacer, lower clapboard is arranged between the input terminus and upper spacer of sterilization pool, and sterilization pool connects chlorine dioxide generator by pipeline, and install pipeline is between the input terminus and lower clapboard of sterilization pool.
The same, the 4th output terminal of MBBR connects artificial swamp (being fit to southern near-thermal band weather condition), and the output terminal of artificial swamp connects the 3rd water pipe.
