Embodiment
Below in conjunction with accompanying drawing, as embodiment, technical scheme is further illustrated.
With reference to Fig. 1, the main body tank 12 of pure oxygen organism fluidization reaction apparatus for treating sewage is made round shape, top, chamber makes water leg 11 within it, be welded into a circular water leg around internal chamber wall, water outlet 10 is installed on the chamber wall of water leg position, horizontal baffle of welding on the internal chamber wall of the bottom that is about main body tank height 1/3rd, evenly distributing on horizontal baffle is fixedly mounted with a plurality of mushroom-shaped filters.Be cone hybrid chamber 15 below horizontal baffle, the cone hybrid chamber vertex of a cone is downward, and opening is equipped with the sewage draining exit 16 that valve is controlled; Cone bottom perimeter and horizontal baffle are welded; In the chamber of cone hybrid chamber 15 wall middle part welding mixing wastewater with air outlet 14, its shape also is cone, and the chamber wall of cone bottom perimeter and cone hybrid chamber 15 is welded, and a through hole is formed on the top, does the mixing wastewater with air outlet.At the flow deflector 6 of the affixed truncated cone-shaped in joint portion of horizontal baffle and main body tank 12 internal chamber walls, the above has serial aperture, and the water that mixes with pure oxygen enters water conservancy diversion letter 7 along flow deflector, and the carrier active carbon in main body tank 12 is in the situation that negative pressure enters guide shell.Play Circulation, channeling, the welding guide shell 7 suitable for reading of flow deflector 6, wall are totally-enclosed, not sealings of top, at one, the guide shell 7 overcoat cylinder with its coaxial line, form a mezzanine space both, as splitter, its top is sealed.The water that mixes with pure oxygen enters water conservancy diversion letter 7 along flow deflector, water, carrier active carbon that both, after mezzanine space of formation, pure oxygen mixes circulate from mezzanine space, flow deflector 6 is integrated with brave the connecing of guide shell 7, form be welded on again on main body tank 12 after integral body, guide shell 7 adopts three spot weld with shunt cylinder 8, internal chamber wall and flow deflector 6 position, junction surface, edge perforates installation back flushing water-ins 13; The peripheral filler particles gac of the cylindrical shell of guide's plate 6 upper surfaces and shunt cylinder 8 or sand, coke, granulated glass sphere, haydite, the ball stopping composition of porous.
Outside main body tank 12, with water inlet incision pipe 17, the incision pipe is water inlet pipe to be inserted the tangent line whirlpool that leans on wall in cylindrical shell, current formation is made progress, lift pump 1 and cone hybrid chamber 15 are communicated with, and in the outside of this pipeline, stopping valve 18 is installed, the water inlet pipe 2 of ejector 3 and outlet pipe are communicated with at the two ends of stopping valve 18, and the middle part of ejector 3 is pure oxygen imports 4.
Sewage treatment process:
Sewage is by lift pump 1; enter ejector 3 by ejector water-in pipe 2; close stopping valve 18 this moment; pure oxygen is entered by pure oxygen import 4; after entering the further diffusive mixing of cone hybrid chamber 15 by water inlet otch pipe 17 tangent lines after air water mixes by ejector; utilize its overbottom pressure to enter flow deflector 6 by mixing wastewater with air outlet 14 by filter 5; guide shell 7 rises and flows into shunt cylinder 8; mix sufficient air water and enter main body tank 12; filling 0.2 1 10mm granulated active carbons 9 in tank body, sewage is rising in tank body.Entered water leg 11 in about 1-1.5 hours, sewage after processing flows out by water outlet 10, when the charcoal fouling too many, when affecting the biological bacteria growth, needing back flushing will break away from mud discharges outside reactor body, reach the demoulding processing capacity, backwashing water is entered by back flushing water-in 13.The gas-water mixing cavity silt particle is discharged by sewage draining exit 16.
The present invention is by bed body, carrier, water-distributing device, device for removing scum, the bed body is that main body tank 12, carrier are also available haydite of gac 9(), water-distributing device is filter 5, device for removing scum is back flushing water-in 13, falls stream district and be the space between main body tank 12 and shunt cylinder 8.Flow deflector 6 guide shells 7 form the up-flow district, water inlet is from bottom to top, then enter shunt cylinder 8.Reaction zone is comprised of inner core and two concentric cylinders of urceolus, and the water-distributing device that microporous aeration device namely is made of filter 5 is located at the bottom of inner core.Fill the carriers such as gac, haydite in reaction zone, for microorganism growth and breeding provide very large surface-area, thereby improved the biomass in unit volume.When pure oxygen and mixed water discharge into inner core up-flow cylinder by the filter device, wrapped folder and the mixing effect of pushing effect in water due to gas, make the mixed solution density of water and carrier reduce and upwards flow, arrive the top, disengaging zone and point out that namely the mouth of a river 13 is to carrier 9 planes, overflow with air pocket afterwards, contain person who lives in exile's urceolus of the water of small bubbles and carrier mixed solution.Because carrier is in ciculation fluidized state, thereby greatly accelerated the relative movement between microorganism and waste water, strengthened effect of mass transmitting, simultaneously can effectively control biomembranous thickness again, make it keep higher biological activity, sewage is processed by discharging by effluent weir after the separate and subside of negative area.
The present invention is with the oxygenate apparatus of biological fluidized bed peripheral hardware, demoulding equipment, greater than the flooding quantity of disposing of sewage and high-lift pump, be combined into one, take pure oxygen as oxygen source, to improve dissolved oxygen concentration in waste water, and in the cone hybrid chamber that arranges in tank body, water inlet combines with the bottom of pure oxygen in cone, because section is little herein, flow velocity is large, and more oxygen is dissolved in water.Can make dissolved oxygen concentration bring up to 30-40mg/L, utilize afterwards the overbottom pressure of lift pump to enter bio-reaction bed and carry out biochemical treatment.
The present invention both had been suitable for the organic waste water of high density, in being suitable for again, the treatment of Organic Wastewater of lower concentration, its organic volumetric loading (in BOD5) can reach 2-1Okg/(m3.d), because required nitrogen phosphorus nutrition is less, especially is suitable for processing the trade effluent that nitrogen phosphorus lacks.The trade effluent of processing comprises phenolic wastewater, α-naphthalenesulfonicacid waste water, Fish canning plant, oil refining sewerage, lactose waste water, slaughterhouse water, coal gasification waste water etc., and the municipal effluent of processing comprises domestic waste water, excrement and urine water, municipal wastewater.Kitchen waste water etc.
What general biological fluidized bed adopted is the air aeration system.This employing oxygen is carried in waste water as source of the gas, has the following advantages:
One, without water smoke, odorless, can not cause secondary pollution to surrounding environment.
Two, the dissolved oxygen consumption of power is low, airborne oxygen partial pressure 21 % that only stand, in clear water, the saturation concentration of dissolved oxygen can only reach 9.17mg/L under standard conditions, can reach 43.7/mg/L under the pure oxygen condition, this shows that the pure oxygen utilization ratio is high, oxygen power is economized, and dissolved oxygen power increases, its than air aeration system can save 60% both more than).
Three, can improve volumetric loading simultaneously, take up an area and economize, working cost is low, and is easy and simple to handle.
