Making Hemp And Degumming Has A Radical Solution.

China

Peng Yanli, director of the Ministry of science and technology development of the Federation of industries, Dong Chunxing, Deputy Secretary General of the vice president of China Textile Association, Dong Xiaojian, deputy secretary of the Xinyu Municipal Committee and representatives of the textile enterprises, attended nearly 200 people.

China is a large country of ramie resources, its planting area and

Output accounts 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 Hong Ke life Engineering Equipment Co., Ltd. Hong Hong Sheng introduced in detail the "innovative hemp biological degumming equipment and intelligent control system", which solved the problem of effective pmission of quality (oxygen), momentum and heat in the process of biological degumming, and provided 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 "biological degumming clean production technology and equipment", which can reduce the bio degumming residue to less than 10%. After 1.5 hours of boiling by 3~4g/L caustic soda, the residual adhesive rate of the product is below 2.5%, and the product reaches the international level and can spin high count yarn. "Jiangxi"

At the same time, the "two pollution" was avoided.

The wastewater treatment process and on-line monitoring system of biological degumming waste liquid are introduced. Based on the traditional filtration, physicochemical flocculation air flotation separation, A/O process, biological treatment, precipitation and decolorization, the project has intensified the aerobic treatment and introduced the biological fluidized bed process. Through the one end aeration and one side diving push, a good oxidation treatment cycle has been formed, which achieves the first level discharge standard of pollutants in the textile industry.

Peng Yanli, director of the science and Technology Department of the Federation, visited the sewage treatment system of the biological fiber degumming and intelligent monitoring system and the degumming waste liquid, said: "the 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 at present, and should be promoted in the whole industry."
