Novel membrane coupled anaerobic bioreactor of the present invention is worked as follows:
The water outlet of step 2, traverse baffle anaerobic reactor 1 gets into tubular membrane ultra-filtration equipment 2 and handles; Water outlet after tubular membrane ultra-filtration equipment 2 filters drains into follow up device, and the anaerobic activated sludge that contains a large amount of mikrobes after tubular membrane ultra-filtration equipment 2 filtering and concentrating passes back into traverse baffle anaerobic reactor 1.
(Anaerobic baffled reactor is to equal early 1980s by the Bachman of U.S. Standford university and Mccarty to put forward a kind of new high-efficiency anaerobic reactor ABR) to traverse baffle anaerobic reactor 1.Some vertical flow deflectors are set in the traverse baffle anaerobic reactor 1, reactor drum is separated into placed in-line several reaction, each reaction chamber is respectively equipped with traverse baffle 13 and anaerobism filler 14, and anaerobism filler 14 is used for fixing mikrobe, strengthens water treatment effect.Each reaction chamber can be regarded a relatively independent upflow sludge blanket as; Waste water get into behind the reactor drum along flow deflector up and down baffling advance; Flow through the successively Sludge Bed of each reaction chamber, the organic substrate in the waste water obtains removing through contacting fully with mikrobe.As shown in Figure 1; The biota gas (biogas) that waste water reaction generated is discharged from traverse baffle anaerobic reactor 1 top; By means of the effect that waste water flows and to rise with biota gas, the anaerobic activated sludge in the reaction chamber moves up and down, but since flow deflector stop the settling property with mud self; Mud flow velocity in the horizontal direction is extremely slow, thereby a large amount of anaerobic activated sludges is trapped within the reaction chamber.Cellular structure that traverse baffle anaerobic reactor 1 is unique and plug-flow attitude make can standard turn out and flow to the sewage quality in this reactor drum, the microflora that envrionment conditions adapts in each reaction chamber; Thereby cause anaerobic reaction to produce separating of acid phase and product methane phase; Two big types of anaerobism crowds can be grown under the optimum separately envrionment conditions; Help giving full play to the activity of anaerobic bacteria flora, improve the treatment effect of system.
The research of laboratory, pilot scale and productivity scale shows that all the ABR reactor drum can be handled the waste water of various concentration in a bigger load range, and it has the advantage that the UASB reactor drum is not had:
1, structural advantages
A, simple in structure does not have moving portion, does not need whipping device, and the waste water flow process of same volume prolongs;
B, hydraulics are good, and useful volume is big;
C, along the longitudinal direction of reactor drum with acid process with produce the methane process separately, reactor drum moves with the biphasic system mode;
D, reduce to stop up and sludge bulking;
E, no special gas-solid liquid separation system;
F, investment and working cost are low;
2, active sludge
A, seed activity mud are not the prerequisites of the good operation of ABR;
B, active sludge interception capacity need solid dielectric or sludge settling chamber by force and not, have higher reactor drum sludge age (STR), and sludge yield is low;
The mikrobe of C, each compartment is with flow process alternation step by step, and the degradation process of gradation law and matrix is harmonious, and it is active to guarantee that corresponding mikrobe has best work mutually;
3, operation
A, hydraulic detention time (HRT) weak point, volumetric loading is high;
B, strong to the adaptive faculty of temperature;
But C periodic running;
D, pulling flow type hydraulic performance guarantee that system still has very high stability when waterpower and organic impact load, have stronger buffering adaptive faculty to toxic substance and inhibitory substance;
E, effluent quality are good;
Sludge characteristics
As far as the ABR treatment process,, have the forming process of granule sludge in this reactor drum, and its speed of growth is too fast though the formation of granule sludge is not the principal element of its treatment efficiency.Generally speaking, this reactor drum initial operating stage (30～45d), this 3～5kgcod/ (m of volumetric loading
3D) time, the granule sludge that particle diameter is 02-05mm can appear.After this, the particle diameter of granule sludge constantly increases, and can reach 2-3mm.The advantage methanobacteria that is similar to methanothrix sp and methanothrix sp genus and Methanosarcina is arranged in the granule sludge, also have heterotrophism methanobacteria and desulphovibrio etc.Importantly, the kind of the anaerobe in the ABS reactor drum in the different compartments distributes and demonstrates good population cooperation, has the superior microorganism population that adapts to the waste water quality that flows into this compartment in the different compartments.For example, at the compartment that is arranged in the reactor drum front end, be main mainly, and in reactor drum compartment at the back, be main then with methanobacteria with hydrolysis and product acid.With regard to methanobacteria; With the passing of compartment, its population is main gradually to the methane phycomycetes by Sarcina, transformations such as heterotrophism methanobacteria and Desulfovibrio; Pursue the variation of chamber like this; Make the superior microorganism population be able to good growth and breeding, pollutants in waste water obtains degraded respectively in different compartments, thereby good treatment efficiency and stable treated effect are arranged.
Because the exclusive structure of ABR can be in the indoor development of different lattice with different microfloras; The microecosystem that each lattice is indoor; All can be dependent on the matrix type and the quantity that are occurred, just as relying on external parameter pH and temperature, is the sarcina methanica of high density in flap reactor drum front portion; Transfer the methane thread fungus to the reactor drum rear portion, this is because sarcina methanica is preponderated than the hyphomycetic height of methane than rate of growth under high acetic acid concentration.Yet the methane thread fungus is owing to its affinity to acetate is preponderated than sarcina methanica is strong under low acetate concentration.
Granular sludge can not only improve the settling property of mud, is beneficial to reactor drum to the holding back of mikrobe, and improves the physiological environment of mikrobe, strengthens their opposing and adaptive facultys of environment to external world, is beneficial to the stability and efficient operation of system.Although prilling is not necessary for optimality concerning the ABR reactor drum, many researchs show that all in the appearance of ABR reactor drum endoparticle mud, the outward appearance of its granule sludge and size be difference with the difference of waste water quality, concentration and processing intent.
