【正文】 dification of a hot topic. Membrane Separation Technology Membrane separation technology of dyeing wastewater by the pollutants in wastewater the separation, concentration and recovery of waste water treatment to achieve the purpose. With no secondary pollution, low energy consumption, can be recycled, wastewater reuse, etc directly. Although membrane separation technology has so many advantages, but there are also unresolved problems, such as membrane fouling, membrane flux, membrane cleaning, and acid resistant membrane material, corrosion resistance and other problems, so at this stage the use of a single membrane separation technology of dyeing wastewater, recycling pure dyes, there are still technical and economic and other issues. Now membrane ultrafiltration membrane treatment technologies, nanofiltration membrane and reverse osmosis membrane. Membrane Treatment of dyeing wastewater salts and COD removal are very good role. Ultrasonic technology Chemical pollutants in water by ultrasonic, especially anic refractory pollutants. It bines advanced oxidation technology, incineration, a variety of supercritical water oxidation technology in water treatment characteristics in a mild condition, degradation, degradation speed, wide application range, can be used alone or in bination with other water treatment technology. The principle of this method is by regulating pond flocculants in selected into the gas wave vibration chamber, in the intense shock oscillation frequency rated under the water, a portion of the anic matter is key to open a small molecule, water molecules in the accelerated 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.
