Abstract
The utility model relates to a continuous-flow double-sludge denitrification dephosphorization process teaching device, belonging to a field of sewage water treatment by the active sludge method, which is composed of a water tank 1, an anaerobic tank 3, a middle sedimentation tank 13, an aerobic bio film denitrification tank 11, an anoxic tank 6, a postpositive rapid aeration tank 7, and a final sedimentation tank that are connected in series; wherein the continuous-flow double-sludge denitrification dephosphorization process teaching device comprises two sets of sludge backflow systems: a backflow sludge circumfluence from the final sedimentation tank 9 to the anaerobic tank 3 and a sludge-exceeding circumfluence from the middle sedimentation tank 13 to the anoxic tank 6; the utility model is characterized in that: an adjusting tank 14 is connected between the water tank 1 and the anaerobic tank 3. The utility model can perform real-time control of water quality by the method of filling medicine into the adjusting tank, the utility model is also equal to a selector, the anaerobic environment can wash out other aerobic microorganism and keep the anaerobic microorganism such as denitrification phosphorus, therefore the utility model has good effect of ensuring the microorganism of each reactor in the system is stable and also preventing sludge from expanding.
Description
Technical field
Technical field under the utility model is: the activated sludge process sewage treatment area.
Background technology
The continuous flow double sludge denitrification dephosphorization process reaches wherein microbial growth characteristic
The continuous flow double sludge denitrification dephosphorization process is to utilize this phosphorus of under anaerobic releasing of denitrification phosphorus-collecting bacterium (DPB), can utilize under anoxic environment
For the microorganism of the excessive suction phosphorus of electron acceptor(EA) is realized removal to phosphor in sewage.The difference of itself and traditional dephosphorization process is to save the energy and carbon source, and the excess sludge of generation is few, is particularly suitable for handling the sewage of this low COD/TN ratio of city domestic sewage.This technology uses two to overlap independently sludge system: with the denitrification phosphorus-collecting bacterium as the Sludge System of main body with the biofilm system of aerobic nitrification microbial film as main body, avoided of the contention of two kinds of microorganisms to substrate, and they are being grown under the adapt circumstance separately, help the efficient operation of technology.Yet aggravation along with eutrophication problem, the urban sewage discharge standard is strict more to the requirement of water outlet phosphorus and nitrogen, and that the wastewater treatment in China ubiquity dephosphorization removing nitric efficiency is low, the energy consumption height, the characteristics that controlled levels is low, so be badly in need of the continuable novel process of this efficient energy-saving of continuous flow double sludge denitrification dephosphorization process, solve the environmental problem of the sternness that China faces better.
But also there is following problem in this technology: when 1. traditional technology requires when the influent quality that changes, often directly in water tank, add material and change influent quality, water quality can only be become a kind of, if require change then also will reconfigure into water.2. each reactor microbe groups instability and sludge bulking of system.3. some larger molecular organicses are not broken down into small molecules.
The utility model content
In order to address the above problem, the utility model proposes a kind of continuous flow double sludge denitrification dephosphorization process instructional device.
This continuous flow double sludge denitrification dephosphorization process instructional device is linked to each other successively by water tank 1, anaerobic pond 3, intermediate sedimentation pond 13, aerobic biologic membrane nitrification tank 11, anoxic pond 6, rearmounted aeration tank 7, final deposition pool 9 fast; Overlap mud backflow systems comprising two: the returned sluge that is back to anaerobic pond 3 by final deposition pool 9 refluxes and is refluxed by the mud that surmounts of intermediate sedimentation pond 13 to anoxic pond 6; It is characterized in that: between water tank 1 and anaerobic pond 3, be connected an equalizing tank 14.
Different being of this device and traditional continuous flow double sludge denitrification dephosphorization apparatus maximum: be provided with an equalizing tank before the anaerobic pond.Its main effect is: 1. real time altering influent quality as required.When traditional technology requires when the influent quality that changes, often directly in water tank, add material and change influent quality, water quality can only be become a kind of, if require change then also will reconfigure into water.And behind water tank, set up an equalizing tank to control influent quality in real time by mode so separately according to the requirement of different periods toward the equalizing tank dosing, optimized traditional technology greatly.2. equalizing tank also is equivalent to a selector switch.Its anaerobic environment can be eliminated other aerobic microbiological (as: thread fungus), keeps this anaerobion of denitrification phosphorus-collecting bacterium, and is stable and prevent that sludge bulking has good effect for each reactor microbe groups of assurance system.3. some larger molecular organicses can be broken down into small molecules in equalizing tank, help it and are further utilized in anaerobic pond.
Description of drawings:
Fig. 1 is the utility model one-piece construction synoptic diagram.
Embodiment
Below in conjunction with accompanying drawing application of the present utility model is described.
Water inlet after equalizing tank 14 is regulated water quality and the mud (returned sluge) that refluxes from final deposition pool 9 enter anaerobic pond 3 together, absorb a large amount of organic substrates and store in vivo at this denitrification phosphorus-collecting mud with the form of PHB, discharge a large amount of phosphorus simultaneously.Mixed solution is behind medium sediment pool 13 sharp separation subsequently, and the supernatant liquor that is rich in ammonia nitrogen and phosphorus flows to aerobic biologic membrane nitrification tank 11, carries out nitration reaction.The poly-phosphorus sludge that precipitates has surmounted aerobic biologic membrane nitrification tank 11 and has directly entered anoxic pond 6 (surmounting mud), is electron donor at this denitrification phosphorus-collecting mud with intravital PHB, the nitric nitrogen that provides with nitrification tank is an electron acceptor(EA), finishes the process of denitrification denitrogenation and excessive suction phosphorus.Mixed solution enters rearmounted aeration tank 7 fast subsequently, and poly-phosphorus sludge further absorbs remaining phosphorus.Final blending liquid is discharged through final deposition pool 9 separation of supernatant, and part mud is back to anaerobic pond 3, and all the other mud are discharged system.
With Beijing university life district sewage (pH=6.95～7.45, COD=201～358mg/L, NH4+-N=42.13～68.98mg/L, TN=54～73mg/L, TP=3.68～9.32mg/L) is an example for former water between the starting period.Through the startup of 22d, the clearance of COD, NH4+-N and PO43--P is by initial about 85%, 85% and 75%, raises and is stabilized to final about 90%, 95% and 95%.
