【正文】 ccelerated thermal motion, flocculant rapid flocculation, decrease chroma, COD, aniline concentration in the waste water, to reduce the concentration of anic waste water of. The present study of ultrasonic technique in water treatment has made great achievements, but most of the studies are confined to the laboratory level. high energy physics method High energy physics method is a new technology of water treatment, when highenergy particles bombarding the water solution, the water molecular excitation and ionization, ion, the excited molecules, secondary electron, the radiation products in the interaction to the surrounding medium diffusion of reaction ability strong, free radicals and substance H HO atoms, and the anic matter of the deposition. Treatment of printing and dyeing wastewater of high energy physics method with anic removal rate high, equipment covers an area of small, simple operation, used to produce highenergy particle expensive, high technical requirements, large energy consumption, energy utilization rate is not high. If you want to truly put into actual operation, still need to do a lot of research. 3 Conclusion Printing and dyeing wastewater is a kind of difficult to industrial wastewater treatment, prevention and treatment of printing and dyeing wastewater pollution are the two aspects plement each other, and actively develop advanced printing equipment, improve the efficiency of the use of dyes and auxiliaries, printing and dyeing wastewater is effective means to reduce harm and using a variety of treatment methods, and make use of circulating water treatment, it can not only to reduce water consumption, but also the environmental pollution of printing and dyeing wastewater effectively reduced. Printing and dyeing wastewater treatment is to remove all kinds of harmful substances in waste water, preventing the pollution of the environment, so that the water can be reused! So that the printing and dyeing wastewater treatment significance: water is a vulnerable to pollution and renewable natural resources. With the increase of the population and economic development, and water pollution is being more and more serious, the shortage of the quantity of water resources available, causing water crisis. According to the water industry point of view, water supply and drainage are the human nature and return to use renewable resources water of the two procedures, in order to make this cycle can continue to serve mankind, water in the natural regression after use, regeneration treatment must be wastewater, so that water will reach the natural selfpurification ability of endurance level, recovery as natural resources attribute. The implementation of sustainable development strategy is of great realistic significance, to create a human health green ecological circle. With increasingly stringent emission standards, indepth exploration of scholars in the printing and dyeing wastewater treatment technology. Believe that with the continuous progress of science and technology, treatment of printing and dyeing wastewater treatment technology will gradually improve, investment, low operation cost, simple processing for printing and dyeing wastewater brings new hope. 。 biofilm decolorization of dyeing wastewater than the activated sludge process. However, there are three biological methods can not solve its own problems: ① Department of residual sludge in higher costs。t remove the dye colloidal and hydrophobic water, and it only cationic dyes, direct dyes, acid dyes, reactive dyes and other watersoluble dye has good adsorption performance. Activated carbon is not the effect on treatment of printing and dyeing wastewater of all types are the same. Activated carbon has selectivity to dyes, the decolorization performance in order of basic dyes, direct dyes, acid dyes and sulfur dyes. Usually activated carbon from animal charcoal, charcoal, carbon to carbon based material through high temperature carbonization and activation. Activated carbon pore, hole, and lack of strong hydrophilic, hydrophobic dye molecules and the limitation of the internal diffusion, applicable to the molecular weight of not more than 400 water soluble dye decolorization, poor decolorization of macromolecules or hydrophobic dyes. Using activated carbon can effectively remove the reactive dyes, basic dyes, wastewater of azo dye. Under certain conditions, activated carbon can also direct adsorption of some heavy metal ions. In addition, carbon adsorption water activity of soluble dye adsorption rate is high, but can not absorb the suspended solids and insoluble dye. Although excellent adsorption performance of activated carbon, but due to the high cost, generally used in low concentration of dye wastewater treatment and advanced treatment.
