The explanation of Reference numeral: 1 is the light-water filler of attached biological film, and 2 is sewage, and 3 is active sludge, and 4 is treating water, and 5 is excess sludge discharge, and 6 are the treating water discharging.
Embodiment is added in sequencing batch activated sludge reactor and is accounted for reactor volume than 10～20%, particle diameter 0.1cm proportion is 0.98 light-water filler, the light-water filler adheres to medium for biomembranous growth provides, thereby forms sequencing batch biofilm-active sludge integrated reactor.Provide precondition owing to adopt proportion to grow for the separation of different types of microorganisms less than the light-water filler of water.Adjustment by operational conditions such as water inlet and aerations makes heterotrophic microorganism and polyP bacteria preferred growth in active sludge, and makes the nitrifier preferred growth in microbial film, and the sludge age separating controlling of nitrifying process and biological phosphate-eliminating process is achieved.The operational process of this sequencing batch reactor comprises anaerobism fill phase, aerobic reaction stage, standing separation stage and bleeding stage, does not have the mix stages of conventional sequencing batch reactor.As shown in drawings, invent the synoptic diagram of four operational processs for present method.1. as shown in Figure 1, the sewage that will contain organic pollutant, nitrogen, phosphor contaminant under the fill phase anaerobic condition evenly enters reactor from reactor bottom, sewage 2 contacts with the active sludge 3 that falls to reactor bottom, make that organism contacts with poly-phosphorus microorganism in the sewage, do not mix in this process, sludge blanket 3 has rising slowly under the effect of ascending current, thereby but owing to action of gravity also can contact with processing sewage in sedimentation.The sewage Short-Chain Fatty Acids is stored with ergastic substances in vivo by poly-phosphorus microorganism absorption and discharges phosphorus, and all the other easily biodegradable organicses are produced short chain fatty acid by poly-phosphorus microorganism absorption by the heterotrophic microorganism fermentation.Because fill phase is not carried out thorough mixing, and the microorganism in reactor top microbial film 1 can not touch organism, so utilize organic heterotrophic microorganism preferred growth in active sludge 3.Absorb organism in the poly-phosphorus microorganism of fill phase and store, discharge a large amount of phosphorus simultaneously with ergastic substances; 2. as shown in Figure 2, in the aerobic reaction stage dissolved oxygen concentration in the reactor is controlled under low oxyty (0.5mg/L) condition by online dissolved oxygen watch-dog or on-line oxidation reduction potential watch-dog, realize synchronous nitration and denitrification and denitrification phosphorus-collecting process, poly-phosphorus microorganism can carry out biological oxidation as electron acceptor(EA) oxidation ergastic substances by the nitrite that nitrifying process produces, excess picked-up phosphorus from environment.Because the microbial film on aerobic stage filler 1 could contact with sewage is mixed, and this moment sewage in most of organism be removed, microorganism in the microbial film can not utilize organic carbon to carry out biological oxidation, can have only the ammonia nitrogen that exists in the sewage for the electron donor that utilizes.Because nitrobacteria is longer generation time, nitrobacteria is more prone to apposition growth and avoids running off from reaction system under the shorter situation of the sludge age of active sludge 3 in addition.In sum, the adjustment heterotrophic microorganism preferred growth by water intake mode and aeration mode is in active sludge 3 and nitrobacteria tends to apposition growth; 3. as shown in Figure 3, after the removal process of pollutent is finished, reactor enters into solids-liquid separation step, nitrifier on the filler 1 floats owing to proportion is less, polyP bacteria in the mud 3, denitrifying bacteria, heterotrophic microorganism are deposited to the bottom of reactor, have therefore realized the separation of different types of microorganisms sludge age.4. as shown in Figure 4, after solid-liquid separation is carried out fully, the sewage 4 after system's emission treatment (process 6), but the poly-phosphorus microorganism of discharge section precipitating sludge 3 (processes 5) control moves under short sludge age condition simultaneously.Also can adjust the sludge age of two kinds of microorganisms by 3 dischargings of control mud and filler 1 demoulding respectively.
