In order to implement the spirit of the Nineteenth National Congress of the CPC and the Law on Promoting Small and Medium-sized Enterprises, strengthen the support for the innovation of small and medium-sized enterprises, and promote the innovation and Entrepreneurship of small and medium-sized enterprises, according to the Circular of the Ministry of Industry and Information Technology on Holding the "Creator China" Innovation and Entrepreneurship Competition in 2018 (Enterprise Letter of the Ministry of Industry and Information Technology [2017] 552), the On May 29, 2018, the "Creator China" Hunan Small and Medium-sized Enterprises Double Creative Competition (Shifeng Competition Area) and the first "Tianxin Cup" Double Creative Competition in Shifeng District, jointly sponsored by Shifeng Science and Technology Bureau, Shifeng Economic and Information Bureau and Shifeng Investment Project Service Center, were held in Zhigu, Zhuzhou Railway.
1. Transformation of new technology achievements in clean production of clean and lead-zinc in Hua Qi
At present, the high alkali flotation process with lime is basically adopted in the lead zinc separation at home and abroad. The main problems of this process are: the recovery of lead and associated gold and silver in lead concentrate is low; lime needs to be mixed into lime milk to add, difficult to wash, and the pipeline of adding reagent and slurry connection are easily blocked, resulting in frequent fluctuation of mineral processing index; the pH value of tail water is above 12, and it needs to add sulfuric acid to adjust to the range of 6-9. Standard discharge; COD content of tail water as high as 100-200 mg/l, need to add oxidant to eliminate treatment; in the lime production process, carbon emissions are serious, the purchase price is higher and higher. For this reason, after many years of technical research in Huaqi, Hunan Province, a lime-free clean separation process of lead and zinc based on pollution source control was developed. The greatest advantages of this process are: without lime, the recovery of lead and associated gold and silver in lead concentrate is greatly improved; without lime, the problems of refractory mixing of lime milk, difficult addition and easy plugging of reagent pipeline and slurry pipeline are eliminated, and the production index is more stable; without lime, the pH value of tail water is 6-9. Within the scope of reaching the standard; without lime, reduce the staffing of lime washing and distribution, reduce the labor cost of mineral processing; use light tension and light compression process, the dosage of reagents is small, the content of COD in tail water is low to about half of the high alkali process.
At present, the project has been popularized and applied in Shuikoushan Nonferrous Group Co, Ltd. and Huangshaping Mining Branch of Zhongtungsten High-tech Co, Ltd, with good market prospects.
1. Provide entrepreneurs with office space, workplaces, conference rooms, broadband and so on, greatly reducing venture capital for entrepreneurs, and enjoy a better office environment.
2. Integration of venture capital sources, rapid docking between the needs of entrepreneurs and investors, to provide financing services for entrepreneurs, to solve the most headache entrepreneurs.
3. Integrating resources to provide counseling and guidance for entrepreneurs, providing entrepreneurship training, avoiding entrepreneurial risks, and helping entrepreneurs to go on better.
4. Provide more detailed solutions for different individual needs, such as technical support, legal advice, intermediary services, offline gatherings, policy popularization, leisure and entertainment, and more diversified services.
The benefits of eco-space mainly come from the successful incubation income of the project, the stock investment income of the project incubation capital, the service income of the pioneer and the pioneer team, the policy of the state and the fund support of the project.
