Owing to adopted above-mentioned technical solution, the operational mode that is about to sequence batch (combines with biomembrance process, the advantage that had both kept general biomembrance process, has the distinctive advantage of microorganism under the sequence batch (operating mode again,, microbial population strong as the microorganism physiological fitness enriches, biomass is big, living microorganism is difficult for running off system's anti impulsion load, flexible operation mode mutability.The utility model reactor assembly is applicable to the processing of various wastewater, as de-carbon, the denitrogenation of municipal effluent, the processing of extraordinary industry or processing wastewater.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model, it is a kind of sequencing batch biofilm reactor system, comprise reactor 3, this reactor 3 contains fixed bed 10, circuit automatic control case 1, external circulation line 11, recycle pump 4, intake pump 5, air pump 2, water inlet vacuum breaker 8 and the circulation vacuum breaker 9 be made up of granulated filler to be formed.
Circuit automatic control case 1 is electrically connected with air pump 2, recycle pump 4, intake pump 5, water inlet vacuum breaker 8 and circulation vacuum breaker 9 respectively;
Waste water pumps into reactor 3 bottoms from water leg 7, by the plug-flow effect of water inlet, second water outlet 34 of treated water from reactor 3 is entered to effluent trough 6 then.
The result of experimental study shows: when the aspect ratio of packing layer post less than 3.7 the time, under the abundant round-robin condition of current, the reactor of step of reaction can be seen complete as.
In above-mentioned reactor assembly, produce different master modes by circuit automatic control case, can make sequencing batch biofilm reactor produce the kinds of processes operation scheme.The cycle of operation of system generally is made up of water inlet, reaction and water outlet three phases.Fill phase mainly is that pending waste water is incorporated in the reactor, and the water outlet stage mainly is that the waste water that will handle is discharged reactor, and step of reaction is the process of effects such as microorganism and pollutent generation biochemical reaction.Step of reaction can be deduced as required and is following several main patterns: (1) aerobic reaction; (2) anaerobic reaction; (3) hypoxia response; (4) above-mentioned pattern is by the complex reaction of different order, the combination of different time mark.The outer external circulation line that is provided with of reactor guarantees that step of reaction has good mass transfer situation, and under the effect of water circulating pump, good water circulation has guaranteed the effect of liquid-phase mixing and mass transfer.The dissolved oxygen that aerobic reaction is required can guarantee by the control air demand according to reaction process.
