The Seminar of the Cleaner Production Technology of Leather and the Using of Tannery Wastewater Recycling Technology was held successfully in Biosk(Shangqiu) Chemicals Co., Ltd. on October 22nd,2016. The board chairman of China Leather Association,Li Yuzhong, The board chairman of Henan Leather Association,Zhu Yan,the professor of Shaanxi University of Science & Technology and the Chief Expert of Dongming Leather Research Institute, Wei Shilin, the professor Zhang Chuanbo, the Vice-principal of College of Light Industry, Textile and Food Engineering Sichuan University, Zhang Zongcai and the professor Peng Biyu,the dean and professor of College of Leather Chemistry and Engineering, Qilu University of Technology,Li Yanchun,the director and researcher of the Leather Research Center of Wenzhou University, Lan Yunjun and other leaders as well as professors;the Chief Engineer of Xingye Technology, Niu Ze，the former Vice General Manager of Guanxing Leather Industry Co.,Ltd,Wang Bingyi, the engineer of Fujian Hualian Industry Co.,Ltd，Shenglin, the Vice General Manager of Huanghua Defu Leather Industry Co.,Ltd, Wang Yijun, the technical director of Liaoning Fuguo Leather Industry Co.,Ltd, Wang Haishan and other famous leaders as well as technical engineers ; the leaders and the technicians from Biosk attended the meeting.Everyone had a comprehensive and profound discussion on the application of development and production of the wastewater recycling technology,which will play an important part in the cleaner production of leather.
The board chairman,Zhu Yan, who's from Henan Leather Association,chaired the meeting. Li Yuzhong,the board chairman of China Leather Association, analyzed the situation comprehensively on the current environmental protection situation faced by the domestic leather industry and leather cleaner production technology at home and abroad,and he has pointed out the necessity and the importance of this seminar. Zhang Zhuangdou, the board chairman of Biosk, gave a speech. In recent years, Biosk has invested about a hundred million,which worked on the research and the promotion of the wastewater recycling technology, and we insisted on the enterprise concept:"Not hanker after fame or gain, But harmony; Protect the environment, Do benefits for the world". Biosk has got more than 10 patents, more and more enterprises has used this technology, and we has made great progress.
The engineer Su Jiasheng, who's from Biosk, gave a report on the the research and the promotion of the wasterwater recycling technology. At present, there has been Xingye Technology and its subordinate companies, Guanxing Leather Co.,Ltd、Hualian Leather Co.,Ltd、Huanghua Defu Leather and other famous enterprises using this technology, and all of them have experienced the process, from doubting to knowing, from knowing to testing, from testing to using. Also, there are some enterprises which have achieved the intention of cooperation with Biosk as well as some enterprises are still taking a wait-and -see attitude toward this technology. The wasterwater recycling technology has gone abroad, it has been tested in one tannery in Australia, and the tannery was very pleased even amazed with this result. What's more, many foreign leather magazines researched and reported the technology.
The professor Jin Liqiang, who's from Qilu University of Technology, gave a report on the microcosmic research into the wasterwater recycling technology in the liming. He pointed the TOC tends to be gentle, and the sulfide isn't increased significantly. The professor Qiang Xihuai, who's from Shaanxi University of Science and Technology, gave a report on n the microcosmic research into the wasterwater recycling technology in the tanning. They took samples in the liming and tanning, and then tested and analysed by the advanced modern precision instruments. So they came to a conclusion that it was feasible to apply the wastewater recycling technology in the liming and tanning，and the quality of products was good .
In order to further know the usage and the production of the wastewater recycling technology,and to solve the problems about the technology, Biosk invited all members to Xingning Leather Industry Co., Ltd.in Xuzhou for field trip, and communicate with the leaders and engineers. There, we solved a lot of problems. Will the waste limed liquid thicken or smell gradually? Will it be overtanning with the waste chromed liquid, for example ,Is it simply operated or controlled ? Will it affect product quality, and so on. Researchers saw the usage of the wastewater recycling technology by themselves. The leaders, experts and the engineers were all amazed by communicating with the leaders and the technicians from this company.
