Background technology
The dyeing waste water water yield is big, the colourity height, and complicated component comprises remaining dyestuff, slurry, auxiliary agent etc. in the dyeing course of processing, and organism is had bigger toxicity, is one of unmanageable trade effluent.In recent years, continuous development along with dyeing industry, the exploitation of new dye and auxiliary agent, especially the continuous increase of azoic dyestuff quantity, cause refractory organic to enter dyeing waste water in a large number, the common department of microbiology method of unifying is difficult to reach the ideal treatment effect, and original biological treatment system mostly drops to 50% even lower by the 70%COD clearance, and traditional treatment process is faced with formidable challenges.
The biological fluidized-bed reactor of development in recent years is fluidization technique and biotechnology bonded product, and with its less investment, floor space is little, the anti impulsion load height, treatment effect good and extremely environmental protection circle pay close attention to.But traditional biological fluidized-bed three phase separating efficiency is not high, causes carrier to run off in a large number; Internal structure is comparatively complicated simultaneously, causes the part biological film excessively to come off, and influences treatment effect.And using gas causes the anaerobic reaction cost too high or be difficult to carry out as promoting power.
Summary of the invention
The purpose of this invention is to provide a kind of fluidized bed processor with dyeing waste water of efficient decolorizing and COD clearance.
The fluidized bed processor of dyeing waste water of the present invention, comprise the anaerobic fluidized bed reactor oxygen flow fluidized bed reactor of becoming reconciled, anaerobic fluidized bed reactor comprises coaxial mounted urceolus, inner core and the tubular triphase separator that is positioned at the inner core top, inner/outer tube diameter ratio is 1: 2, the triphase separator barrel dliameter is greater than the inner core barrel dliameter, in the anaerobic fluidized bed reactor bottom water-in and nozzle are arranged, circulating outlet and water outlet are arranged at top, sealing cover is arranged at the top, has covered the air outlet, and water-in links to each other with wastewater trough through intake pump, circulating outlet links to each other with nozzle through recycle pump, and the microbe carrier that circulates is arranged in anaerobic fluidized bed reactor;
Aerobic fluidized bed reactor comprises coaxial mounted urceolus, inner core and the tubular triphase separator that is positioned at the inner core top, inner/outer tube diameter ratio is 1: 2, the triphase separator barrel dliameter is greater than the inner core barrel dliameter, at aerobic fluidized bed reactor bottom aeration head and water-in are arranged, water outlet is arranged at top, and the bottom water-in links to each other with the water outlet of anaerobic fluidized bed reactor, aeration head links to each other with aerating apparatus, and the microbe carrier that circulates is arranged in aerobic fluidized bed reactor;
Anaerobic fluidized bed reactor is become reconciled has several thief holes respectively on the wall of the outer-rotor of oxygen flow fluidized bed reactor.
The become reconciled microbe carrier of oxygen flow fluidized bed reactor of microbe carrier in the above-mentioned anaerobic fluidized bed reactor is shell preparing active carbon particle, shell preparing active carbon particle surface has by the microbial film that exists the microorganism adhering growth to form in the waste water, and shell preparing active carbon particle diameter is 2-3mm.
Principle of work:
Waste water enters anaerobic fluidized bed reactor through intake pump from water-in in the wastewater trough, recirculated water is extracted out by recycle pump from the top circulating outlet, spray into by bottom nozzle, microbe carrier rises in inner core in the promotion anaerobic fluidized bed reactor, reach after the tubular three-phase separation area sedimentation on anaerobic fluidized bed reactor top from the urceolus gravity settling, rise once more after arriving the anaerobic fluidized bed reactor bottom, successively circulation.Microbe carrier can not gone out with water outlet in anaerobic fluidized bed reactor, can constantly degrade to waste water.Emitted through the air outlet, top by the gas of microorganisms in the anaerobic fluidized bed reactor, the top water outlet is connected with aerobic fluidized bed bottom water-in, and the anaerobic fluidized bed reactor water outlet enters aerobic fluidized bed reactor via pipeline.Aerobic fluidized bed reactor bottom has aerating apparatus, and the microbe carrier that promotes in the aerobic fluidized bed reactor by aeration head generation tiny bubble rises, and rises to three-phase separation area through inner core and enters the urceolus gravity settling.Aerobic fluidized bed water outlet is discharged by the top water outlet.Degraded situation under the different heights can be by analyzing from different thief hole water samplings.
Before the reactor start-up, earlier two fluidized-beds are all filled water, bubble is driven out of from recycle pump, the anaerobic fluidized bed reactor median water level should be higher than circulating outlet.Start recycle pump and aerating apparatus, allow the anaerobic fluidized bed reactor liquid circulation in the oxygen flow fluidized bed reactor of becoming reconciled, add biofilm carrier, filling ratio is advisable with 5%.Anaerobic fluidized bed reactor with the lid sealing, is guaranteed anaerobic environment in the reactor.Start intake pump, dyeing waste water is entered by anaerobic fluidized bed reactor bottom water-in, and even with liquid mixing in the anaerobic reactor, water outlet is simultaneously flowed out from the anaerobic fluidized bed reactor water outlet, enters aerobic fluidized bedly further to degrade.
Apparatus of the present invention compact construction is simple, floor space is little, in aerobic, anaerobic fluidized bed reactor, the tubular triphase separator of barrel dliameter greater than the inner core barrel dliameter is set, not only simple in structure and have good gas-liquid-solid three-phase separating effect, improved the phenomenon that carrier runs off significantly.In anaerobic fluidized bed, adopt recirculated water to substitute aerating apparatus as promoting power, guaranteeing successfully anaerobic reaction to be introduced fluidized-bed reactor under the condition cheaply.In aerobic, anaerobic fluidized bed reactor, introduce the biomembranous absorbent charcoal carrier that is loaded with that circulates respectively, have the characteristic of degrade azo dyestuff rapidly and efficiently, colourity and COD
CrClearance height, effluent quality are good.The solution of apparatus of the present invention success the susceptible to plugging technical barrier of conventional packed bed, having can dynamic processed continuously advantage, can be used for the processing of multiple dyestuff.
