Making Hemp And Degumming Has A Radical Solution.

The key technology achievements of "textile light" jointly sponsored by the Ministry of science and technology development of the China Federation of textile industry, the China Textile Industry Association and the textile optical science and technology foundation of education, were held in Xinyu, Jiangxi. Peng Yanli, director of the Ministry of science and technology development of China Federation of textile industry, Dong Chunxing, Deputy Secretary General of the vice president of China Textile Association, Dong Xiaojian, deputy secretary of Xinyu Municipal Committee, and nearly 200 representatives of Jute Textile Company attended the event.

China is a large country of ramie resources. Its planting area and fiber output account for more than 90% of the world's total. However, the traditional chemical degumming method of ramie is used in sulfuric acid soaking and the high temperature boiling of Ramie with caustic soda. It not only has high production cost, serious fiber damage, but also reduces the quality and spinnability of refined linen, and the wastewater discharged by it also has serious environmental pollution. In order to speed up the innovation and development of the textile enterprises and promote the energy conservation and environmental protection of the textile industry, the promotion of the new technological achievements of "efficient energy saving hemp fiber biological degumming processing" can not only greatly reduce energy consumption and chemical raw materials, reduce the discharge and treatment costs of sewage, but also help improve the hemp fiber properties.

In the promotion activities, Professor Cao Junwei of Wuhan University first introduced the "successful selection and degumming process optimization of efficient degumming bacteria", which can replace the strong acid and strong alkali chemical process for biological degumming, remove 70% of the gum from the original hemp, and then refine it with low concentration of charcoal and auxiliaries.

Nanjing Hui Ke life Engineering Equipment Co., Ltd. Hong Hou Sheng introduced in detail the "innovative hemp biological degumming equipment and intelligent control system", which solved the problem. Biological degumming The effective transfer of quality (oxygen), momentum and heat in the process provides a good environment for suitable production of degumming bacteria. It can save 52.80% of coal per year, save water by 62.67%, reduce the consumption of chemical raw materials by 62.27%, and reduce COD0.357 tons per ton of products than chemical degumming projects, and reduce COD8925 tons annually. The treated wastewater can be recycled, and the economic and social benefits are obvious.

Zhu Teye introduced the "Jiangxi Da Ma Century Technology Co., Ltd." Biological degumming clean production technology and equipment "This project can reduce the biological degumming residue to less than 10%. After 1.5 hours of boiling by 3~4g/L caustic soda, the residual adhesive rate is below 2.5%. The product reaches the international level and can spin high count yarn. At the same time, the "two pollution" was avoided.

　　 Jiangxi Zhang Kaifeng introduced the "sewage treatment process and on-line monitoring system of biological degumming wastewater". The project enhanced the aerobic treatment by introducing the traditional filtration, physicochemical flocculation air flotation separation, A/O process, biological treatment, precipitation and decolorization, and introduced the raw material processing technology. Through the one end aeration and one side diving push, a good oxidation treatment cycle of the sewage in the pond was formed, which reached the first level discharge standard of pollutants in the textile industry.

Peng Yanli, director of the science and Technology Department of the China Federation of textile industry, visited the sewage treatment system of the biological fiber degumming and intelligent monitoring system and the degumming waste liquid. He said: "leading enterprises like delta are not only the example of the scientific and technological innovation in the industry, but also the pioneer of energy conservation and environmental protection in the textile industry, and should be promoted in the whole industry."
