The utility model has a rectangular or circular external shape, the diameter of the utility model is 1.5 to 8 m, and the height of the utility model is 2 to 6 m. One to twenty isolated type aerators each of which is composed of an aeration barrel and an aeration head are arranged in the utility model, and the isolated type aerators which can be arranged in the center or at the circumference of the internal-circulation aerobic oxidizing bioreactor are designed to have a rectangular or circular arc shape. The filler area 4 is arranged in the bioreactor, and the entire reactor is formed after the filler area 4 is filled with fillers. The utility model can be used for treating muddy solution (water).
Description
Technical field:
The utility model relates to sewage disposal device, can be applicable to the sewage disposal such as trade effluent, city domestic sewage, reuse water of high and low concentration.Mainly be meant a kind of improvement to traditional BAF.
Technical background:
It is the sewage treatment process of developing in recent years that BAF (BAF) is disposed of sewage, widely popular America and Europe and Japan, but less in China's research.The characteristics of BAF maximum are to integrate bio-oxidation and hold back suspended solids, have saved post precipitation pond (as second pond).In addition, this treatment process volumetric loading, hydraulic load are big, and floor space, initial cost are few, oxygen transfer rate height, characteristics such as energy consumption is low, working cost is low, and effluent quality is good, sludge output is few.But in traditional B AF technology, make the oxidation of pollutent mainly concentrate on reactor end (about 0.5m) with filtering because of filtering velocity that it adopted is lower, the capacity utilization in whole filter tank is low, simultaneously owing to the maldistribution of gas-liquid-solid three-phase in the packing layer is easy, aeration channel short circuit phenomenon occurs, reduce processing efficiency.Its process range mainly is confined to city domestic sewage processing aspect simultaneously, and industrial sewage especially high-concentration sewage is seldom related to.
Summary of the invention:
The purpose of this utility model provides a kind of and can make waste liquid (water) treatment efficiency height for overcoming the prior art defective exactly, and is simple in structure, the internal-circulation type biology aerobic reactor that cost is low.
Internal recycle aerobe oxidation reactor is compared with traditional B AF technology, bigger change is arranged aspect aeration mode, therefore its volumetric loading, hydraulic load further improve, move more steady, broken through the forbidden zone that traditional B AF technology can not be handled high-concentration hardly-degradable sewage simultaneously, have organism volumetric loading height, hydraulic load is big, hydraulic detention time is short, required initial cost is few, the effluent quality advantages of higher, and high-sulfur, prussiate, phenol, CODcr, ammonia nitrogen are all had adaptability and removal ability preferably.
The characteristics of internal recycle aerobe oxidation reactor are by adopting the characteristic filler and the novel isolated aeration technology of the high cavity rate of lightweight, big flow internal recycle current of inner formation in the biological filter, the biologic packing material bed can utilize the sewage self characteristics to cultivate the superior microorganism phase that this sewage is possessed adaptability rapidly in this internal recycle stream, form the good bio-oxidation bed of exclusive performance, in long-term operation, be aided with efficient gas filter bed back flushing proprietary technology and keep biophasic activity, thereby form an efficient height, biological filter that stability is good.So both strengthened the mass transfer velocity of pollutent between water and biophase, pollutent is more evenly distributed at filter material layer, improved the volumetric efficiency of reactor, avoided traditional aeration mode washing away again to filtrate, can prevent the loss of the microorganism that the generation cycles such as thiobacterium, nitrifier are long quite effectively, safeguard biophasic integrity.And the internal recycle of flow makes the filter tank possess the characteristics of complete mixing reactor greatly, and the sewage quality that enters reactor obtains dilution, thereby has improved the ability and the impact resistance of the anti-toxic substance of reactor, makes its range of application wider, moves more stable.The biomass density of cultivating in the sophisticated internal circulation biological filter can reach 20kg/m
3Filler is being handled common sewage, high sour water and is being carried out sewage when nitrated, and the volumetric loading of its corresponding each pollutant can reach 7.2kgCODCr/m respectively
3.d, 4.8kgS
2-/m
3.d, 1.2kgNH3-N/m
3.d, when carrying out advanced treatment, water outlet can reach middle water water quality standard fully.The purpose of this utility model is achieved in that it is made up of shell of reactor, separation net, isolating cylinder, aeration inner core, aeration head and packing area, is made up of every inner region isolating cylinder and aeration cylinder.Be respectively if group half an arc aeration isolating cylinder has at least one (root) to expose to the sun from tube in isolating cylinder on week in reactor; In reactor central authorities are separation nets, and the isolating cylinder inner bottom part is equipped with aerator, and the bottom side offers the water back window, and the top is submerged in the water.Internal recycle aerobe oxidation reactor built-in 1-20 isolated aerator, be arranged in internal recycle aerobe oxidation reactor central authorities or all around.Isolated aerator can be designed to rectangle or circular arc.Isolating cylinder and aeration cylinder are fixed on the stuffing frame.
Water during aeration in the isolating cylinder obtains oxygenation, and under the lifting of bubble, formation is vertical water circulation at center with the isolating cylinder, makes the sewage of handling in it constantly carry out aeration aerating reaction degraded repeatedly by aeration zone, packing area, thereby reaches the purpose of handling dirty (liquid) water.
It is made up of the utility model housing 1, effluent weir 2, isolated aerator 3, packing area 4 and filler bracing frame 5, it is characterized in that profile is rectangle or circle, be of a size of diameter 1.5-8m, highly be 2-6m, in arranged 1-20 isolated aerator, isolated aerator is made up of aeration cylinder, aeration head, and it is central or all around to be arranged in internal recycle aerobe oxidation reactor, isolated aerator can be designed to rectangle or circular arc, is packing area 4 in the reactor.
Advantage of the present utility model is simple in structure, the treatment efficiency height, and cost is low.
