Abstract
The utility model relates to a multi-pipe air stripping internal-loop three-phase biological fluidized bed, which belongs to the technical field of environment-friendly sewage treatment apparatuses. The utility model mainly comprises a fan-connected aeration pipeline, a group of aeration members arranged on the aeration pipeline, a group of air stripping pipes arranged above the group of aeration members, and another group of air stripping pipes arranged inside a fluidized bed. By increasing the number of air stripping pipe, the utility model can increase the volume of cavity and change speed of carrier biomembrane, enhance the bioactivity, improve the capacity of sewage treatment, and accelerate the degradation of sewage matrix. The utility model provides a high-efficiency sewage treatment process.
Description
Technical field:
The utility model relates to a kind of multitube gas and carries inner loop three phase fluidized bed reactor, belongs to environment protection sewage treatment unit technical field.
Technical background:
Before the utility model is made, in prior art, to sewage treatment equipment is various informative efficiently, but with this equipment more approaching be the inner loop three phase fluidized bed reactor that usually adopts inside and outside cylindrical shell to form.As the up-flow district, as falling stream district, inner barrel rises by carry under one's arms current and biological particles of aeration this structure between outer cylinder body and the inner barrel with inner barrel, descends falling stream district's current and biological particles, has formed internal recycle.This structure increases treatment capacity and can only reach by amplifying barrel diameter increase cylindrical shell height, but to form the required air capacity of complete fluidisation when above and will roll up when inner barrel is amplified to diameter 400mm, the power consumption of the unit water yield will increase, and the influence that highly is subjected to blower pressure can not be done very highly, thereby influenced the expansion of treatment capacity, can only make the fluidized-bed that is fit to little water yield processing.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of knockdown stripping tube to be arranged in the biochemistry pool, reach the purpose of bio-carrier fluidisation, can improve the replacing speed of carrier biofilm, increase biological activity, the multitube gas that helps improving sewage treatment capacity is carried inner loop three phase fluidized bed reactor.
Main solution of the present utility model is achieved in that
It mainly adopts blower fan 1 to connect aerating pipelines 7, and one group of aeration head 6 is installed on aerating pipelines 7, corresponding to one group of aeration head 6 top 5, one groups of stripping tubes 5 of one group of stripping tube is installed and is installed in the fluidized bed body 3, installs in fluidized bed body 3 bottoms to start the attached device 10 that helps.
Description of drawings:
Fig. 1 is the utility model structural representation:
Embodiment:
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model adopts blower fan 1 to connect aerating pipelines 7,6, one groups of aeration heads 6 of one group of aeration head is installed above aerating pipelines 7 is adopted two of aeration heads at least.And 5, one groups of stripping tubes 5 of one group of stripping tube are installed above corresponding to one group of aeration head 6 are adopted at least more than two, stripping tube 5 diameters are 200～400mm.Forming aerating apparatus by above-mentioned major parts is installed in the fluidized bed body 3.Dividing plate 13 is installed in rising pipe 12 front ends, and its effect prevents to vulcanize carrier 8 and runs out of fluidized bed body 3.Sulfuration carrier 8 can adopt particulate materials such as sand, haydite, activated carbon, coke, for microorganism growth provides huge surface-area.Sewage water inlet pipe 2 is installed on the fluidized bed body 3, and water distributor 4 is installed on the sewage water inlet pipe 2, can play the effect of water distribution uniformity.Water outlet crest of weir 11 is installed in rising pipe 12 front ends.
Working process of the present utility model: sewage is through water inlet pipe, flow into fluidized bed body uniformly by water distributor, under the situation of air pump air feed, (pass through micro-hole aerator, at stripping tube bottom aeration), flow velocity in each stripping tube reaches more than the 0.3m/S, the shearing action that fluid causes, can improve the replacing speed of carrier biofilm, the bio-carrier that is deposited on the bottom is sucked stripping tube by liquid and gas, finish oxygenation in stripping tube, the process of demoulding and rising is gone out the liquid of stripping tube and bio-carrier is finished absorption and degradation of organic substances in falling stream district 9 process, the part micro-bubble also will be brought into and fall the stream district, increase the dissolved oxygen in the water.Sewage has the good condition of separating that connects in fluidized bed body, fluid medium has very high specific surface area and biological concentration, and residence time 30-120 minute enough, is 10-20/one of activated sludge process.
Compared with the prior art the utility model has the following advantages: 1, owing to adopted suitable air lift Pipe is arranged in biochemistry lets out, and reaches the purpose of bio-carrier fluidisation, only needs the number of corresponding increase stripping tube Amount just can increase lets out the body volume; 2, because the flow velocity in each stripping tube reaches more than the 0.3m/S stream The shearing effect that body causes can improve the replacing speed of carrier biofilm, increases biologically active, is conducive to Improve disposal ability; 3, can not flow out with current owing at the delivery port front end dividing plate, bio-carrier being installed The pond body; 4, because the alternate close contact of bio-carrier, waste water, air three has improved the mass transfer shape greatly Attitude. Therefore, the degradation speed of waste water substrate is very fast, has formed a kind of efficient waste water treatment process.
