Description
Technical field
The present invention relates to trade effluent innoxious process for treating field, be related specifically at a kind of cloth dyeing industrial sewage
Science and engineering skill.
Background technology
Dyeing is the industry that textile industry water consumption is bigger, and water participates in the whole dyeing and finishing course of processing as medium.Printing and dyeing dirt
The water water yield is big, and colourity is high, complicated component, containing dyestuff, slurry, auxiliary agent, oil preparation, soda acid in sewage, and fiber impurity and inorganic salt
Deng, in dye structure, nitro and the heavy metal element such as amine compound and copper, chromium, zinc, arsenic have bigger bio-toxicity, seriously
Pollute environment.According to statistics, within 2010, in national each industrial trade, textile printing and dyeing industry quantity of wastewater effluent is 12.75 tons, occupies complete
The 5th of state's industrial wastewater discharge amount, accounts for the 6% of whole nation industrial wastewater discharge amount.Show according to relevant information, Taihu Lake basin
In trade effluent COD (CODcr) discharge capacity, about 30% derives from textile printing and dyeing industry.The pollution problem of dyeing and printing sewage is
Become the social problem of extensive concern.
Dyeing and printing sewage is mainly by desizing sewage, boiling-off sewage, bleaching effluent, mercerising sewage, dyeing waste and stamp sewage
Composition, has that the water yield is big, concentration is high, variation water quality is big, content of organics is high, intractability is relatively big, part of contaminated water has containing poisonous
The features such as pest matter .Owing to dyeing and printing sewage is containing substantial amounts of organic pollution, enters water body and will consume dissolved oxygen, destroy Ecology
Balance, jeopardizes Fish and other hydrobiological existence.Demersal Organic substance, can produce hydrogen sulfide etc. because of anaerobic digestion
Harmful gas, adverse condition.The color and luster of dyeing and printing sewage is deep simultaneously, has a strong impact on receiving water body outward appearance, and with general biochemistry
Method is difficult to remove.Coloured water body also can affect the transmission of daylight, is unfavorable for the growth of aquatic organism.Meanwhile, dyeing and printing sewage major part
Meta-alkalescence, enters farmland, can make saline Land；The sulfate of dyeing waste can be converted into sulfuration under the reducing condition of soil
Thing, produces hydrogen sulfide.
Dyeing and printing sewage is the organic sewage of the complicated component based on organic contamination, and the main object of process is BOD5, no
Easily biological-degradable or biodegradation rate Organic substance slowly, basicity, coloring matter and a small amount of noxious substance.Although printing and dyeing dirt
The biodegradability of water is the most poor, but in addition to the most special dyeing and printing sewage (such as pure chemical fiber textile dyeing), still belongs to and can biological drop
The organic sewage solved.Its processing method, based on biological treatment, needs to be aided with pretreatment and the physical chemistry degree of depth of necessity simultaneously
Facture.In conventional treatment technology, activated carbon adsorption processing cost is high, and regenerates difficulty；Membrane separation technique is disposably thrown
Money is big, and technical difficulty is big, and membranous system cleans difficulty, and the backwash water yield is big, and operating cost is high, and regular job is complicated, runs and ties up
Protect costly；Photocatalytic degradation speed is fast, does not produce secondary pollution, but titania photocatalyst need to utilize ultraviolet light as energy
Amount energy consumption is high, and the photocatalyst response rate is low simultaneously, all limits photocatalytic oxidation application in Pollutant Treatment；Electrolysis
Or the technique such as plasma-catalytic oxidation to there is again energy consumption high, fluctuation of service, through engineering approaches application difficult and and traditional handicraft
It is difficult to the problems such as combination.Although it is fast that catalytic ozonation method has degradation speed, flow process is simple, does not produce the excellent of secondary pollution
Point, but there is also that energy consumption is high, ozone utilization rate is low, catalyst activity is relatively low and the problem such as catalyst recycling difficulty.
