Description
Technical field
The invention belongs to field of waste water treatment, in particular to a kind of integrated conduct method of cotton dyeing waste water.
Background technique
In dyeing production process, waste water caused by cotton dyeing usually contains higher COD and higher
Salinity causes residual dye concentration high since reactive dye dye-uptake is low, and coloration is high, and biodegradability is poor.It is general higher
Salinity will have a direct impact on the activity of microorganism in biochemical treatment system, salinity contained therein is mainly Na2SO4, due to SO4 2-
The presence of ion, excessively high sulfate concentration can inhibit anaerobic biological process, influence biochemical disposed of in its entirety effect.Therefore, cotton
There is decoloration hardly possible in dyeing waste water, salinity is high, and the phenomenon easily exceeded there are tail water phenyl amines index, and these problems will be that printing and dyeing are useless
Water process urgent problem to be solved.
Currently, the main method for treatment of dyeing wastewater has several techniques such as physico-chemical process, biochemical method, chemical method to combine
Combination treatment method.Part printing and dyeing enterprise also starts the method using shunting of removing contamination, dual treatment, and source of generation carries out waste water
High and low sub-prime is collected and is handled, and reduces processing cost to a certain extent, is recycled to effluent part, generally but
The thinking of end treatment is still continued, the recycling of material is not implemented.It is added especially to cotton dyeing waste water, in dyeing course a large amount of
Salt assitant finally by discharge of wastewater, result in waste of resources.The presence of salt residue and dyestuff simultaneously, to useless under a certain concentration
The biological production liveliness proof of water biochemical system inhibits, thus generally require by special bioreactor by bacteria selection with
The means such as domestication, activity activator carry out bioreactor performance promotion.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of integrated conduct method of cotton dyeing waste water, this method
It solves high chroma, the high salinity, the processing problem of biodegradability difference of dyeing waste water, breaches cotton fabric biological wastewater treatment work
The limitation of skill.
The present invention provides a kind of integrated conduct methods of cotton dyeing waste water, comprising:
(1) cotton fabric dyeing process raffinate is discharged into raffinate water tank and is extracted, the two-phase liquid flowed out from raffinate water tank is logical
Enter compressed air and is sent into three phase separation tank；Color oil of the three phase separation tank top discharge containing dyestuff, is sent into color oil collecting tank, color oil
Collecting tank recycles extractant by back extraction, and the dyestuff raffinate being concentrated is sent into conditioning tank I；The discharge of three phase separation tank lower part
High level salt solution, high level salt solution are sent into salting liquid collecting tank utilization (can be back to dyeing) to be recycled；
(2) high-concentration waste water in pre-treatment workshop section is discharged into conditioning tank I, the dyestuff raffinate with the concentration in step (1)
Mixing, and pH value is adjusted to neutrality；Waste water in low concentration wastewater and the remaining workshop section of dyeing in pre-treatment workshop section is discharged into tune
Save pond II；
(3) by the waste water in conditioning tank I be sent into resistance to sulfate it is anaerobic fluidized bed in degraded and decolourized, resistance to sulfate is detested
After the water outlet of oxygen fluidized bed is mixed with the waste water in conditioning tank II, it is sent into aerobic biochemical system and carries out biological treatment, through sedimentation basin
Biological aerated filter processing is re-fed into after coagulating sedimentation.
Extractant in the step (1) is complexing agent 15-45%, cosolvent 10-30%, surplus are diluent；Wherein,
Complexing agent is one or both of trioctylamine, benzoic acid, and cosolvent is one or both of isomery alcohol, n-octyl alcohol, dilution
Agent is petroleum ether or sulfonated kerosene.
The workshop section that pre-treatment generates high-concentration waste water in step (2) includes one or more of desizing, kiering, concise；
It includes one or more of bleaching, washing that pre-treatment, which generates the workshop section of low concentration wastewater, in step (2).
Dyeing residue workshop section in the step (2) includes one or more of rinsing/washing, fixation.
Dehydration waste liquid in cotton dyeing final finishing workshop section is discharged into conditioning tank II；In cotton dyeing final finishing workshop section
Discarded finishing fluid is discharged into conditioning tank I.
Resistance to sulfate in the step (3) is anaerobic fluidized bed using Mo-bearing Iron Ores as filler, granular size 200-400
Mesh, concentration 0.05-0.25kg/m3。
The anaerobic fluidized bed disengaging mode of resistance to sulfate in the step (3) is bottom in and top out formula, and upflow velocity is
0.8-1.2m/h, water outlet crest of weir arrange 60 mesh wire nettings, and Mo-bearing Iron Ores and mud granule is prevented to be lost；Hydraulic detention time is greater than
36h can realize extension hydraulic detention time by water outlet circulation and the concatenated mode of multiple reactor.
By Mo-bearing Iron Ores particle be placed in resistance to sulfate it is anaerobic fluidized bed in, pass through the anaerobic fluidized bed upflow velocity of control and top
Effluent weir flow velocity realizes that stop and fluidization of the Mo-bearing Iron Ores particle in anaerobic reactor are uniformly distributed, using molybdenum-iron element to hydrolysis
The effect that anaerobic fluidized bed resistance to sulfate inhibits is played in anaerobic bacteria activation in acidification.
The hydraulic detention time of aerobic biochemical system in the step (3) is greater than 24 hours.
The hydraulic detention time of biological aerated filter in the step (3) is greater than 8 hours.
The present invention for the higher cotton dyeing waste water of saliferous take be reasonable distribution and interflow waste water mechanism, will contain
The higher dense dyeing waste-water of salt after being stripped with cotton fabric desizing, that concise/kiering waste water is mixed into resistance to hydrolysis acidification with high salt is anti-
It answers device to handle, can be recycled after processing through staining solution with high salt extracted, solve the problems, such as that salt is difficult to remove.
Desized wastewater, kiering waste water in pre-treating technology section can also contain a large amount of organic matter, can use these organic matter tune in this way
The biodegradability for saving reactor for hydrolysis and acidification is avoided since the too low caused sludge of organic substrates cannot remain sufficiently high dense
Degree, influences effluent quality.The resistance to anaerobic fluidized bed middle packing layer of sulfate can not only filter some suspended materials, also have and inhibit
SO with high salt4 -2Effect.
Beneficial effect
(1) present invention realizes the resource utilization of cotton fabric dyeing process waste liquid salt and water, solves the high color of dyeing waste water
Degree, high salinity, the processing problem of biodegradability difference, breach the limitation of cotton fabric biological process of wastewater treatment.
(2) present invention has been achieved at low cost the recycling of salt in dyeing waste-water, in anaerobic fluidized bed hydrolysis acidification
Stage can remove the pollutants such as 60% or more residual dye.
(3) present invention does not have to change original dyeing production method, handles high chroma, high salinity dyeing waste-water at low cost,
And existing sewerage processing difficulty is significantly reduced, strengthen Hydrolysis Acidification microbiological treatment waste water efficiency under high salt,
The degradation and decoloration and phenyl amines processing up to standard of realization cotton dyeing waste water；High salinity solution extracted can recycle,
Avoid influence of the salt to aftertreatment systems.
