Fig. 1～2nd, the most preferred embodiment of the utility model further specifies below in conjunction with 1～2 pair of the utility model of accompanying drawing:
Embodiment
With reference to accompanying drawing 1～2:
This kind circulation self-stip carrier organism filtration reactor comprises support 1, reactor shell 4, fills inner chamber 5, lifter 6, carrier distribution clearer 7, effluent weir 8, sewage draining exit 9, aerator 10, water distributor 11 and the equalizer 12 of carrier filtrate.Housing 4 installs and fixes through support 1; Housing 4 upper openings, the setting triangular in shape of vertical section, bottom, housing 4 xsects are circle, rectangle or ellipse; Reactor drum inner chamber 5 central upper portion places set up a carrier distribution clearer 7; Carrier distribution clearer 7 belows connect the lifter of vertically installing 6, housing 4 top inner ring fixed installation effluent weirs 8, and effluent weir 8 becomes the ring groove of L shaped setting for the vertical section; The top is lower than the top of housing 4, and the sewage draining exit 9 that housing 4 one sides are provided with connects carrier distribution clearer 7.
Working process is following:
The utility model is when work; Can be divided into three sections from top to bottom successively through technical matters inner chamber 5 as required: aerobic zone, oxygen-starved area and anaerobic zone, waste water needs the sewage of filtration treatment through water-in 2 to the anaerobic zone injection of the bottom of inner chamber 5 by water distributor 11, and the rising water body passes through with this; Anaerobism, anoxic, aerobic three sections; Aerator 10 obtains filtering in the carrier filtrate of sewage at inner chamber 5 through the oxygen-starved area gas distribution of inlet mouth 3 to inner chamber 5 bottoms, obtains the top of filtering water at inner chamber 5; Get in the effluent weir 8, then through discharging the outside of housings 4 with effluent weir 8 joining water outlets 16.In this process, the PM for particulate matter in the waste water under the effect of media filtration, obtain removing, and the organism in the water body is by the mikrobe that adheres on the bio-carrier filtrate, absorption, degraded, digestion.Air by aerator 10 in the oxygen-starved area, aerobic zone carries out gas distribution, the rising microbubble is long in the following residence time of crown_interception of bio-carrier, has increased the duration of contact with water body, the transfer efficiency of oxygen is high.
Simultaneously, the microbial film that comes off on inner chamber 5 bottom biofilter materials and filtering PM for particulate matter and the bio-carrier is together risen under the effect of air-lift unit in the water storage platform 13 on reactor drum top by lifter 6; Insert in the clear water zone straight-tube portion bottom that water shoot 14 vertically is provided with, and this part straight tube upwards promotes a part and filters good clear water, and the water in the water storage platform 13 is discharged sewage to be cleaned through the part body that water shoot 14 is obliquely installed; At this moment; Clear water can carry out back flushing to sewage, and the mud that washes out will flow at circulation tube 15 internal recycle, and sewage can separate cleaning through the carrier clearer 7 that distributes like this; After separating cleaning; The bio-carrier filtrate is back in the reactor drum through water shoot 14 again, and under the guiding function of the equalizer of tilt installing 12 uniform distribution, thereby avoided occurring the problem at cleaning dead angle; Avoided the obstruction of equipment; Formed of the reciprocation cycle self-stip of bio-carrier filtering material particle, and carrier distribution clearer 7 isolated mud are discharged housing 4 outsides through sewage draining exit 9, thereby guaranteed the continuous operation of equipment at inside reactor.
In addition, the living weight of the utility model is big, can reach 30～45g/L, and the withstand shock portative power is strong, and the removal amount is big, and organic loading can reach 10kgCOD/M
3More than the d, technology satisfies anaerobism, anoxic, aerobic three conditions, has possessed the processing requirement of dephosphorization denitrogenation; Its air micro-bubbles is under the crown_interception of carrier filtrate; The efficiency of conversion of oxygen is higher, and the utilising efficiency of oxygen can reach 35～40%, has reduced a large amount of power consumption.
The above; It only is the preferred embodiment of the utility model; Be not to be the restriction of the utility model being made other form, any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified as the equivalent embodiment of equivalent variations.But every the utility model technical scheme content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of the utility model technical scheme according to the technical spirit of the utility model.
