Description
Technical field
The invention belongs to the waste water treatment applications technical field, be specifically related to a kind of method that adopts immobilized fungal mycelia to decolorizing printing and dyeing waste water.
Background technology
Dyeing waste water is the waste water that processing cotton, fiber crops, man-made fiber and DYE PRODUCTION and the course of processing are discharged.The dyeing waste water water yield is bigger, and as 100～200 tons of 1 ton of textiles water consumptions of printing and dyeing processing, wherein 80～90% become waste water.Contain a large amount of pollutents in the dyeing waste water, cause that wherein the higher reason of its colourity is wherein to contain a large amount of dyestuffs, these dyestuffs are divided into azo, anthraquinone, heterocycle, tritane etc. from structure, also contain a large amount of inorganic salt, sulfide in addition in the dyeing waste water, and multiplely have an organism that bio-toxicity or three causes performance.A lot of dyeing waste water color and lusters are dark, and biodegradability is low, and are very big to the human health influence.
Have the water of color and luster, be disposed to open water supply, generally should not drink,, enter water body and also can cause the water body transmittance to reduce the destruction that causes water ecosystem even remaining dye component concentration is very low in the waste water.Therefore, the decolorization of dyeing processing is the main task that dyeing textile and DYE PRODUCTION are faced always.The physico-chemical process of decolorizing printing and dyeing waste water processing at present mainly contains adsorption bleaching technology, coagulating sedimentation technology, chemical oxidation technology, ion exchange technique, ultra-filtration membrane decolouring technology, photocatalysis technology, high-voltage pulse electrolysis tech etc.The shortcoming of physico-chemical process is the processing costs height, produces a large amount of difficult mud and may cause secondary pollution problems.Along with development of biology, utilize microorganism to decolour and receive increasing concern.Biosorption process is cheap, and adsorptive capacity is big, need not add medicament, has advantages such as convenient operation and management and processing costs be low, has become one of new method of removing this pollutant.Domestic and international many scholars use fungies such as white-rot fungi, mould, Aspergillus fumigatus and have carried out biological decolouring experimental study to dyestuff, and the result shows that biological process has good potential application foreground in dye wastewater treatment.But how fungi is carried out immobilization to improve treatment effect and to prevent that it is problem demanding prompt solution that thalline runs off always.Fungi is carried out immobilization be about to fungi and be fixed on the solid material with cell texture, make it to have certain volume, physical strength and porosity.Immobilization technology commonly used mainly contains absorption, embedding, crosslinked etc., and fixing agent has silica gel, gelatin, glutaraldehyde etc.Usually this class can make the activity of bacterial strain reduce after material immobilized, and immobilization cost height, complex process.
