    Analysis Of The Future Of China'S Printing And Dyeing Wastewater Treatment Equipment

    With the deepening of reform and opening up, China's economy has entered a period of rapid development.

    Printing and dyeing industry

    The volume of drainage increased considerably.

    With the continuous development of water treatment equipment, according to incomplete statistics, the annual discharge of printing and dyeing wastewater in China is about 20 billion tons, which is located at fifth of the total industrial wastewater discharge in China.

    The resulting environmental damage and huge economic losses.

    China's textile printing and dyeing are mostly small and medium-sized private enterprises, scattered scattered, waste water is not easy to concentrate on processing, and the overall production level is not high, the volume of pollutants per unit product is more than twice that of the developed countries.

    Small and medium-sized enterprises are small in scale.

    The dyeing workshop is usually intermittently produced, or the production quantity of the order is small and the water quality fluctuates greatly. The sewage treatment system can not operate stably and effectively.

    Because small and medium-sized enterprises are generally unable to bear the investment and operation cost of sewage treatment system, most of their wastewater has not been effectively managed, resulting in serious environmental pollution.

    Due to the limitation of the existing technology level, a large number of printing and dyeing wastewater reuse will bring a series of problems to the production and wastewater treatment system, including the accumulation of organic pollutants and inorganic salts.

    At present, there are few studies on the long-term reuse of wastewater and the impact on the water treatment system, especially the accumulation of inorganic salts.

    Printing and dyeing wastewater is of poor biodegradability and difficult to decolorization. The decolorization effect of printing and dyeing wastewater is one of the key indicators to evaluate whether the wastewater treatment method is effective.

    The common way of treatment is flocculation and flocculation, and the negative treatment method of biochemical reactivation. The project has large area, long process, high cost of infrastructure and operation, and unstable treatment effect. Most of the dyestuffs are soluble in water because of the current dyeing medium, and because of the large mass of dye molecules, most dyes can form hydrophilic colloids in water, making the conventional decolorization of printing and dyeing wastewater become very difficult. Therefore, more economical and effective decolorization methods and technologies for printing and dyeing wastewater that can remove biodegradable organic compounds need to be adopted.

    The strategic alliance of technology innovation for wastewater treatment and recycling industry in textile printing and dyeing industry is one of the first pilot projects of strategic alliance of industrial technology innovation for water pollution control and control.

    To solve the problem of development and industrialization of key technologies in wastewater treatment and recycling of textile and dyeing industry, we should gradually establish a high level, open sharing experimental platform and industrial test base to jointly solve the technical bottlenecks in the development of the textile printing and dyeing industry, improve the recycling rate of water resources in textile printing and dyeing industrial parks, reduce the environmental pressure of the printing and dyeing industry, build up the technology pfer and diffusion mechanism of the alliance, and accelerate the popularization and application of key technologies and products of the Independent Innovation textile printing and dyeing industry, which can stimulate domestic demand and form new economic growth points, so as to achieve the rapid application of industrialization, commercialization and scale of scientific and technological achievements, and speed up the technological upgrading of the wastewater treatment and recycling industry in the textile printing and dyeing industry, and promote the healthy development of the textile and dyeing industry. The alliance is based on the development of circular economy, building a strategic goal of resource saving, environment-friendly and ecological civilization construction, and working together through open industrial technology innovation strategic alliances.
