Description
Technical field
The invention belongs to waste water treatment applications technical field, be specifically related to a kind of co-immobilization white-rot fungi thalline that adopts to the method for decolorizing printing and dyeing waste water.
Background technology
Dyeing waste water refers to the waste water that processing cotton, fiber crops, man-made fiber and DYE PRODUCTION and the course of processing are discharged.Its generation is large, and to process 1 ton of textiles, water consumption needs 100 ~ 200 tons, and wherein 80 ~ 90% become waste water.What dyeing waste water contained mainly contains organic pollutants is the dyestuff causing its colourity higher; In addition, also containing a large amount of inorganic salt, sulfide, and multiple there is the organism that bio-toxicity or three causes performance.Dyeing waste water color and luster is dark, COD is high, and biodegradability is low, and the subject matter of therefore dyeing textile and the solution of DYE PRODUCTION needs is its desolventing technology always.Based on the coloured groups of dyestuff chemistry structure, dyestuff can be divided into azo, anthraquinone, tritane etc.The physico-chemical process of current decolorizing printing and dyeing waste water process mainly contains absorption method, membrane separation process, chemical oxidization method, reduction method, electrochemical process.The main drawback of physics and chemistry method dye wastewater treatment is poor efficiency, likely produces the larger by product of toxicity; Range of application is narrow, and working cost is higher.
Along with the development of biotechnology, utilize microorganism to carry out decolouring and receive increasing concern.Domestic and international many scholars apply the fungies such as white-rot fungi, mould, yeast and have carried out and study the biological decolouring of dyestuff, result shows that biological process has a good application prospect in dye wastewater treatment, but current research is in only simply simulates in dye decolored level by lower concentration, composition, and how improving treatment effect is problem demanding prompt solution always.Therefore, for the feature of dyeing waste water, the method that the dye molecule developed in a kind of energy efficient degradation waste water also can repeat decolouring has great using value.
Immobilized microorganism technology utilizes physics or chemical means to be positioned by free microorganism in the area of space of restriction, makes it to keep biological activity and the method that can recycle.It becomes possibility by for the normal growth of microorganism and catalyzed reaction, the distribution in the reactor of control biomass, effective separation of reaction product and the optimizing of realization response process control.The microorganism of white-rot fungi belongs to Basidiomycetes, Ascomycetes and deuteromycetes on taxonomy, because it is saprophytic on trees or timber, invades wood cell chamber, and release degrading enzyme, causes woodenly rotting into white sponge agglomerate, thus gain the name.Dyestuff thoroughly can be degraded to CO by secreted degradation enzyme system by them
2and H
2o, has good decolorizing effect.Due to the lignin-degrading enzymes limitednumber of single white rot fungus secretion, cannot Wastewater Dyes be made fast thoroughly to degrade, so can set up the method for the white-rot fungi co-immobilization of different genera, the complementation of enzyme system, and be applied to the degradation and decolorization of different dyeing waste water.The establishment of the method, not only can realize fully degrading thoroughly to the dyestuff of different structure, and can protect the biological activity of mycelium and enzyme, make it from the destruction of mechanical force, reach the object of multiple batches of desolventing technology dyeing waste water.At present white-rot fungi co-immobilization is carried out treatment of dyeing wastewater still to appear in the newspapers and lead in end.
