The Adsorption-Biodegradation Anaerobic Sequencing Batch Reactor (AB-ASBR) To Process The High Organic Concentration Waste Research

The adsorption-biodegradation anaerobic sequencing batch reactor is in A, in the B two sections of reactors distinguishes selectively the raise take the methane sarcina, the methane silk fungus as the superiority fungus pellet sludge. A section under the short water power resident time, the high organic load condition moves, in the reactor has the high ethanoic acid density adaptation methane sarcina the living environment, this stage's major function is the anaerobic active sludge to enters in the water the non-soluble organic pollutant to play the adsorption elimination role; B section enters the water by the soluble organic matter primarily, raises take the methane silk fungus as the superiority fungus anaerobic pellet sludge, carries on the biodegradation response.This topic is under the warm 35±1℃condition, carries on by the whole milk powder matches the water artificially, in enters the water Concentration respectively is 6500mg/L,9000mg/L,10000mg/L, 11000mg/L, the corresponding volume load is under 10gCOD/(Ld),15gCOD/(Ld),16gCOD/(Ld),18gCOD/(Ld) operating mode reactor's movement effect carries on the inspection to AB-ASBR. Obtains the following conclusion through the experiment: 1,In the anaerobic adsorption stage, with does not carry on the agitation and the intermittence stirs two ways to compare, stirs the way to be able continuously to be best to A section of anaerobic pellet sludge adsorption rate adsorption effect, the adsorption rate achieves 69.06%; A section of anaerobic pellet sludge removes the COD effect to the organic pollutant adsorption to be very obvious, in 6500mg/L, 9000mg/L, 10000mg/L, the 11000mg/L four kind of organic density situations get down except rate to achieve above 80%, explained that A section of anaerobic pellet sludge can have the good adsorption elimination function under the high organic density condition to the organic pollutant.2,The regeneration can enhance A section of anaerobic pellet sludge the adsorption performance.In the entire regeneration time,the COD density drops continually in previous 5 hours,after regenerating 5h,COD,VFA basic invariable, this reflects in the sludge to be possible the biodegradation organic pollutant to disappear basically exhausts,may explain that the regeneration already completed,from this then determined that the best regeneration time is 5h.3,After the highly concentrated waste water passes through A section achieves the adsorption equilibrium, water leakage after precipitation enters B section to carry on the biodegradation, B section maintains invariable basically after the 6h, COD density, may think that B section of biodegradation completes, this time the total COD elimination rate achieves above 96%.The above conclusion confirmed under the high organic load to adsorb - the biodegradation anaerobic foreword to approve the type active sludge law (AB-ASBR) the craft feasibility.
