The concrete characteristics of the utility model also have; Constitute mud backflow seam between above-mentioned inner core two wall bottoms and the reactor body; The top of next-door neighbour's mud backflow seam is provided with splash pan on the said reactor body, and reactor body is provided with and the corresponding shore pipe in splash pan position.
Above-mentioned inner core one is cylindrical tube shape with inner core two.
The beneficial effect of the utility model is:
1, the characteristics that have the traditional biological fluidized-bed
This treater has the process characteristic that many general activated sludge processes and biomembrance process do not possess; Show that mainly organic loading is high, treater internal flow mixing mass-transfer performance is good, and the mass-transfer efficiency of oxygen is high; Living weight is big; Anti impulsion load, advantage such as the pressure-losses is low, the matrix in the waste water fully contact with homodisperse microbial film in bed and obtain degraded and remove.Because strenuous exercise, collision between the inner bio-carrier of treater; The microbial film of carrier surface is brought in constant renewal in, and not only can effectively control biomembranous excessive increase, and mikrobe also is in increased logarithmic phase all the time; Biological activity is high, thereby has guaranteed the efficient processing performance of treater.
2, have three-phase biologic fluidized-bed characteristics
This treater is the basis with the biomembrance process, has drawn the fluidization technology in the chemical industry operation, and the gas, liquid, solid three-phase medium is placed in the same reactor drum, and district's formation internal recycle flow system flows with falling in the up-flow district.Have the three-phase biologic fluidized-bed distinguishing feature of three-phase fluidized bed:
1. air from three-phase bed bottom direct aeration, both for mikrobe provides oxygen,, can control microbial film thickness excessive increase again for the carrier fluidisation provides power.
2. since gas, liquid, solid in the up-flow district with fall between the stream district and circulate; Speed of circulation is very big; Much larger than the EM settling velocity; The shearing action that fluid forms can be controlled microbial film thickness effectively, increases with the inner transmission matter resistance of avoiding blocked up microbial film to cause, makes circulating fluid bed middle microbial film keep higher activity.
3. because the turbulent fluctuation shearing and the hydraulic friction of internal-circulation type fluidized-bed come off blocked up microbial film voluntarily, therefore can prevent a large amount of losses of carrier, the number of dropouts of carrier seldom.
4. can remove organic pollutant at a high speed; BOD volumetric loading rate can be up to 5 ㎏/(
), and treating water BOD value can guarantee at 20 ㎎/below the L
5. the transfer efficiency of oxygen is high, and liquid is at upspout and fall between the stream pipe and circulate, and gas, liquid are long duration of contact.
3, the characteristics that have biological contact oxidation process
1. filling surface is covered with by microbial film entirely, forms biomembranous agent structure.On microbial film, can form the stable ecosystem and food chain.
2. owing to carry out aeration, biofilm surface is constantly accepted aeration stripping, helps keeping biomembranous activity like this; Suppress the propagation of anaerobism film, also be suitable for the utilization ratio that improves oxygen, therefore; The active biomass that can keep higher concentration; Processing efficiency is high, helps dwindling the pond and holds, and reduces floor space.
3. the hollow ball filler is when aeration; The biomembranous packing density of having grown approaches water, and filler relies on the stirring action of aeration tank, is in flow state; Make sewage and frequent the contacting of the microbial film on the filler; Filler cuts bubble in flow process, make gas distribution more even, and the utilising efficiency of oxygen is improved.Therefore, under the situation of certain pollutants removal rate, the residence time of sewage in the pond is shorter than traditional biological contact oxidation method, and simultaneously, the ability of anti impulsion load is strengthened.
4. the hollow ball filler is suspended in the water surface when aeration not, and fixed support needn't be set, and the installation and the maintenance that make the main body reaction tank are easily.
4, the characteristics that have activated sludge process
Raw waste water gets in the pond from the aeration tank head end, and the mud that is refluxed by tube settler also gets into synchronously.The mixed solution that sewage and returned sluge form is pulling flow type and flows in reactor drum.Thereby can make wastewater treatment efficiency fabulous, and the BOD clearance is also higher, and effluent quality is better.
5, the characteristics that have tube settler
This treater places inside with tube settler, has reduced capital cost, and the part mud that this structure also is beneficial to post precipitation refluxes.It is little to have made full use of the tube settler surface load, and clearance is high, and the residence time is short, the advantage that floor space is little.
6, the characteristics that have synchronous denitrification dephosphorizing
The mixed solution of sewage and mud is pulling flow type and advances in treater, in the process of circulating, successively experienced aerobic section, anoxic section, anaerobism section, thereby be similar to A
2/ O technology has the effect of synchronous denitrification dephosphorizing.
7, the characteristics that have the biological filter
At the outer haydite of filling of treater, form bacteria filter structure, the advantage that so just can make full use of ordinary biofilter promptly: the ⑴ treatment effect is good, and the BOD5 clearance can reach more than 95%; ⑵ stable, be easy to management, save the energy.The treated device of sewage is handled the back and is got into the biological filter through the perforation water distributor, and the air in the treater is sent into the bottom, biological filter with blast main and carried out oxygenation.The practical technique that has so just made full use of the detergent power of haydite and handle to have disperseed sewage effluent makes the filter tank not only can remove organic pollutant, but also can remove pollutents such as the nitrogen that causes body eutrophication, phosphorus, no mud generation.
