Description
Technical field
The invention belongs to technical field of environment protection equipment, the pretreatment system of especially a kind of anthraquinone dyes production waste water and
Using.
Background technique
Anthraquinone dyes produce chroma in waste water height, and major pollutants are anthraquinone type organic, and waste water COD is higher, and ammonia nitrogen contains
Amount is higher, contains certain salinity, and sewage composition is complicated, and aromatic structure is not easy to be destroyed, and biodegradability is poor, BOD5/COD < 0.1,
It is decolorized slowly, and contains organic dyestuff in waste water, strong toxicity, pH fluctuation is big, and change of component is big, if not preprocessed, directly
Into sewage treatment plant, sewage treatment plant inflow water quality, water will be caused larger fluctuation occur, and high oil-containing, sulfur-containing waste water will
Very detrimental effect is generated to biochemical treatment system, causes effluent from WWTP water quality not up to standard, surrounding enviroment is caused greatly
Harm.
By retrieval, following two patent publication us relevant to present patent application are found:
1, a kind of dye wastewater processing system (CN107986553A) provides a kind of dye wastewater processing system, including
Grid pond, Powder ash adsorption pond, sedimentation basin one, activated carbon adsorption tank, sedimentation basin two, anaerobism photo-biological turntable, aerobic moving bed
Membrane bioreactor, grid pond and Powder ash adsorption pond, sedimentation basin one, activated carbon adsorption tank, sedimentation basin two, anaerobism photo-biological turn
Disk, membrane-moving bed biofilm reactor are sequentially connected；Dye wastewater processing system of the present invention, first joint uses flyash, work
Property charcoal adsorption treatment is carried out to dye wastewater, dye molecule, reduction salt and metal ion content can recycles from sewage, and right
COD is effectively removed, good decolorizing effect, improves the biodegradability of sewage, later using anaerobic-aerobic combination method to waste water
It is further processed, so that sewage is realized effective detoxification treatment, dramatically increase the removal rate of COD, may ultimately reach 96%
More than, while the present invention invests, operating cost is low, process flow is reliable and stable.
2, the anaerobic in low temperature processing unit (CN207330514U) of a kind of industrial wastewater discloses a kind of the low of industrial wastewater
Warm anaerobic processing device, structure include: anaerobic reactor, anaerobic reactor bracket, low-temperature condenser, membrane bioreactor,
Anaerobic in low temperature processing pedestal, waste water water conservancy diversion tubule, waste water water conservancy diversion extra heavy pipe, double header Rose Boxes, Industry Waste moisture groove body, deslagging are led
Pipe, washing filtering ponds, sewage aerobic pond, takes out pipe circulatory pool at sewage aerobic groove body, and anaerobic reactor of the present invention is equipped with second level three-phase
Separator, deep purifying reaction chamber, anaerobic reactor down-comer, level-one three phase separator, fluidized-bed reaction room, anaerobic reactor
Shell, low temperature water distributor realize inside the anaerobic in low temperature processing unit low-temperature condenser cooperation anaerobism generator of industrial wastewater
Water distributor efficiently sprinkle water cooling anaerobism cooperation processing sewage and waste water, make industrial wastewater anaerobic in low temperature handle linking cooperation more
Efficiently, and conjugation is high, and double acting faster handles waste water.
By comparison, there is essential difference in present patent application and above-mentioned patent publication us.
Summary of the invention
It is an object of the invention in place of overcome the deficiencies in the prior art, provide a kind of the pre- of anthraquinone dyes production waste water
Processing system and application, the system is reliable for operation, operating cost is low, characteristics of compact layout, reduces land occupation and investment cost, which produces
Raw mud amount is less, predominantly activated sludge, subsequent easy to handle, and the water inlet that sewage treatment plant can be reached after sewage disinfection treatment is set
Count limit value condition.
