Abstract
The invention discloses a UV (ultraviolet)/O3+BAF (biological aerated filter) advanced oxidation sewage treatment facility which comprises a UV/O3 catalytic reaction region, a supporting layer and haydite filter material layer region and a water outlet region, wherein the supporting layer and haydite filter material layer region is provided with a BAF. By combining the UV catalytic O3 oxidation and microbial degradation technique, the facility lowers the sewage treatment cost and enhances the COD (chemical oxygen demand) removal rate.
Description
Technical field
The present invention relates to a kind of waste disposal plant, relate in particular to a kind of UV/O
3+ BAF built-up type advanced oxidation sewage disposal device.
Background technology
BAF is the sewage treatment process that contact oxidation technology and suspended substance filtration process are combined, its technological principle is in filter tank, to load the particulate filter that a certain amount of particle diameter is less, the filter material surface microbial film of growing, the inner aeration in filter tank, effluent stream through time, owing to adhering to high-concentration biological film amount on filtrate, utilize the pollutent in its strong oxidative degradation ability fast degradation waste water, simultaneously, utilize feature and biomembranous biological flocculation that particle diameter of filter medium is less, hold back a large amount of suspended substances in sewage, and ensure that the microbial film coming off can not drift out with water, reach thus the object of purifying liquid waste.But be subject to the restriction of microbiological deterioration ability, BAF can not be processed the waste water that contains a large amount of hardly degraded organic substances.Its main drawback is: (1) BAF is had relatively high expectations to the SS of water inlet, needs to adopt the pretreatment technology that S is had to higher position reason effect.And the concentration of water inlet can not be too high, otherwise easily cause filtrate conglomeration, obstruction.(2) can not process high concentration hard-degraded organic waste water, generally, influent COD generally can not exceed 2000mg/L, and this has also just limited its sewage disposal scope.
Summary of the invention
The object of this invention is to provide a kind of UV/O
3+ BAF built-up type advanced oxidation sewage disposal device, it can high-level efficiency, process at low cost difficult for biological degradation organic waste water.
The present invention is achieved like this, a kind of UV/O
3+ BAF built-up type advanced oxidation sewage disposal device, comprises UV/O
3catalytic reaction zone, supporting layer and ceramic grain filter floor district, exhalant region, wherein UV/O
3gas-liquid mixing pump, ozonizer, ultraviolet lamp tube are contained in catalytic reaction zone, and supporting layer, aeration tube, filler, filter are contained in supporting layer and ceramic grain filter floor district, it is characterized in that UV/O
3bottom, catalytic reaction zone is connected with inhalent siphon, before inhalent siphon, is connected with gas-liquid mixing pump, and gas-liquid mixing pump is connected with ozonizer; UV/O
3top, catalytic reaction zone is provided with a back flushing water inlet pipe and back flushing inlet pipe; Supporting layer and bottom, ceramic grain filter floor district are provided with supporting layer, filter, arrange filter on supporting layer; Supporting layer and middle part, ceramic grain filter floor district are provided with aeration tube; The packing layer that supporting layer and top, ceramic grain filter floor district are attached growth of microorganisms; Exhalant region is overflow device, and bottom is connected with normal rising pipe and back flushing rising pipe.
Further, the normal rising pipe of water outlet water table ratio of described back flushing rising pipe is low.
Advantage of the present invention is: (1) ultraviolet catalyzed is effective, O
3oxidation capacity good, UV/O
3synergistic action effect is remarkable, has reduced cost of sewage disposal, and the rate of removing of COD is high; (2) UV/O
3the excessive O of remnants in technology
3can float and be utilized by microorganism, vent gas treatment cost is few, non-secondary pollution.(3) UV/O
3technology and ripe BAF technical combinations, processing efficiency is high, economical and practical, has generalization; (4) in equipment running process, every key index is monitored in real time, ensures treatment effect and security.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
In the drawings, 1. normal rising pipe 9. back flushing rising pipe 10. filter 11. back flushing inlet pipe 12. ultraviolet lamp tubes of gas-liquid mixing pump 2. ozonizer 3. back flushing water inlet pipe 4. supporting layer 5. aeration tube 6. packing layer 7. shell 8..
Embodiment
As shown in Figure 1, a kind of UV/O
3+ BAF built-up type advanced oxidation sewage disposal device, comprises a shell 7, in shell 7, is divided into UV/O
3catalytic reaction zone, supporting layer and ceramic grain filter floor district, exhalant region, wherein UV/O
3in catalytic reaction zone, establish ultraviolet lamp tube 12, UV/O
3bottom, catalytic reaction zone is connected with inhalent siphon, before inhalent siphon, is connected with gas-liquid mixing pump 1, and gas-liquid mixing pump 1 is connected with ozonizer 2; UV/O
3top, catalytic reaction zone is provided with a back flushing water inlet pipe 3 and back flushing inlet pipe 11; Supporting layer and bottom, ceramic grain filter floor district are provided with supporting layer 4, filter 10, arrange filter 10 on supporting layer 4; Supporting layer and middle part, ceramic grain filter floor district are provided with aeration tube 5; The packing layer 6 that supporting layer and top, ceramic grain filter floor district are attached growth of microorganisms; Exhalant region is overflow device, and bottom is connected with normal rising pipe 8 and back flushing rising pipe 9.The normal rising pipe 8 of water outlet water table ratio of described back flushing rising pipe 9 is low.
Sewage water inlet pipe road accesses gas-liquid mixing pump 1 together with ozonizer 2, according to the suitable ozone of the concentration adjustment of pollutent and sewage proportioning, the sewage and the ozone that are pumped to catalyzed reaction pond react under the katalysis of ultraviolet light 12, and high density refractory organic is degraded to readily biodegradable organism.
Contain easily biodegradable organics sewage and be to support fixing filter 10 by an effect of supporting layer 4(supporting layer 4, another effect is that block ultraviolet line enters BAF) in filter 10 enter BAF, BAF mainly comprises packing layer 6 and aeration tube 5, microorganic adhesion is grown on packing layer 6, aeration tube 5 passes into fresh air, under the effect of microorganism, readily biodegradable organism is thoroughly decomposed, thereby obtains conforming with the clean water of emission standard.
A small amount of ozone floating of failing to have reacted in catalyzed reaction pond enters BAF, self redox reaction occurs and generates oxygen, supplies with microorganism growth breeding, has reduced ozone and has discharged the pollution that environment is produced, and is conducive to again the renewal of microorganism simultaneously.
Back flushing water inlet pipe 3 and back flushing inlet pipe 11 are regularly opened, and for purifying BAF, remove the clogged material such as mud on filter and wash away dead microorganism.
