Description
Technical field
The utility model relates to a kind of waste water pretreatment system, especially a kind of useless flue gas associated treatment dyeing waste water system.
Background technology
Dye species is ten hundreds of, approximately has the dyestuff of 10%-20% to discharge with waste water in the dyeing and printing process process, and every discharging 1t waste water from dyestuff will pollute the 20t water body.Dyestuff in waste water can absorb light, reduces water transparency, causes visual pollution.Waste water from dyestuff is one of unmanageable trade effluent, has the advantages that colourity is dark, alkalescence is large, organic pollutant content is high and change of water quality is large.Most of dyestuffs are poisonous hardly degraded organic substance, and chemical stability is strong, have carcinogenic, teratogenesis, mutagenesis; Directly harm humans is healthy, and also havoc water body, soil and ecotope, cause unthinkable consequence.Effectively solving the waste water from dyestuff governing problem is the key point of eliminating the dyeing development bottleneck.
Dyestuffs industries is especially outstanding with the pollution problem of waste water from dyestuff in polluting.In the last few years, the annual quantity of wastewater effluent of China reached more than 390 hundred million tons, and wherein industrial sewage accounts for 51%, and waste water from dyestuff accounts for 35% of total industrial wastewater discharge, but also was increasing year by year with 1% speed.Every discharging 1t waste water from dyestuff just can cause the pollution of 20t water body.In every profession and trade, the COD quantity discharged of printing and dyeing textile comes the 4th, and discharging is increasing year by year than escheat.
The bipseudoindoxyl dye chroma in waste water is high, the water yield large, alkalescence is large, moiety is complicated, belongs to one of more unmanageable trade effluent.Dyestuff is the principal pollutant in waste water from dyestuff, with all kinds of colour developing groups (as-N=N-,-N=O etc.) and segment polarity group (SO, Na ,-OH ,-NH), complicated component, great majority are take aromatic hydrocarbons and heterocycle as parent, belong to the organic pollutant than difficult degradation, are also the important source of pollution one in each large waters of China.Most of organic dye chemical stabilities are strong, have and three cause (carcinogenic, teratogenesis, mutagenesis) effect, are typical poisonous Persistent organic pollutants.In addition, the dyestuff in waste water can absorb light, reduces the transparency of water body, unfavorable to hydrobiont, microbial growth, and reduced the self-purification capacity of water body, cause simultaneously visual pollution, havoc water body, soil and ecotope are directly with harm humans is healthy indirectly.
The important prerequisite of administering waste water from dyestuff to the effective degraded of bipseudoindoxyl dye and treatment technology.For the characteristics of most of dyestuff chemistry stable in properties, hard degradation, the various countries scientist pays much attention to the degraded of dye well waste water from dyestuff and the research for the treatment of process.Along with the development of scientific-technical progress and Pollution abatement technology, the mankind have also found the method for a lot of effective dye wastewater treatment using, sum up the biological integrated process of pre-treatment one.Usually pretreatment process mainly comprises coagulation sedimentation, membrane separation process, advanced oxidation processes.
1, coagulation sedimentation
Coagulation sedimentation is the method that present dye wastewater treatment using effect is more stable, technique is comparatively ripe.Generally accepted mechanism has bridge linking effect, compression is double-deck, net is caught and the charge neutrality effect.The coagulating agent self-characteristic has determined the quality of its settling property, and a lot of environmental factorss comprise that temperature, pH and Eh etc. may play promotion or restraining effect to sedimentation function.In recent years, inorganic polymer flocculant becomes the focus of research coagulation-flocculation behavior and mechanism.
There is following defective in coagulation sedimentation:
1. the coagulating agent chemical feeding quantity is large, and running cost is high;
2. sludge yield is large, and supporting sludge treatment device cost is high.
2, membrane separation process
Membrane separation technique has that technique is simple, less energy-consumption, environment is not produced the advantage of polluting.Utilize ultrafiltration process that the waste water of bipseudoindoxyl dye is processed, can realize the direct reuse of the highly concentrated solution of dyestuff, can be used as neutral water through liquid and be recycled utilization.
There is following defective in membrane separation process:
Due to film pollution, concentration polarization and too fast replacement frequency, the price of film is more expensive in addition, makes the high cost of membrane separation technique dye wastewater treatment using, has greatly limited membrane separation technique and has administered application and the popularization of industry at waste water from dyestuff.
3, advanced oxidation processes
Advanced oxidation processes is the decomposition by oxygenant in katalysis quickening system, and make it with water in organism react rapidly, cause in the short period of time organic pollutant oxidative degradation.Advanced oxidation processes mainly contains Fenton reagent method, ultraviolet catalyzed method, Ozonation, chlorine oxidation process and several method and unites use.
Advanced oxidation processes has good removal to the colourity in bipseudoindoxyl dye waste water and organism, but the working cost height limits the use of this pretreatment process in the bipseudoindoxyl dye wastewater treatment always.
Although the pretreatment process to indigo waste water is a lot of both at home and abroad, all there is the limitation of self in the whole bag of tricks, is not that treatment effect is not good enough, is exactly that running cost is too high, or selective to the processing of waste water.Materialization treatment process is all to utilize chemical reagent or electric energy that waste water from dyestuff is processed, exist not high to organic matter removal efficient, strong to the selectivity of dyestuff, processing costs is high, operation is uneconomical, produce a large amount of unmanageable mud, easily cause the shortcoming such as secondary pollution, applies being very limited.
The utility model content
The useless flue gas associated treatment dyeing waste water system that the utility model provides that a kind of working cost is low, treatment effect is reliable and stable.
