Hebei Guohui Environmental Protection Technology Co., Ltd

1、 Hebei Guohui Environmental Protection Technology Co., Ltd. is a subsidiary of Shanghai Guohui Group (with 99% equity). It is a high-tech innovative environmental protection enterprise driven by both technological innovation and business model innovation. Its main business areas include comprehensive utilization of solid waste resources, air pollution control, open water pollution control, ecological restoration, etc. With years of technological breakthroughs and environmental governance achievements, the company has obtained investments from well-known investment companies such as Softbank China Capital, CICC Capital, Zhenghai Capital, and Aladdin Environmental Protection, leveraging capital to achieve leapfrog development. Since its establishment, the company has always attached great importance to international scientific and technological cooperation. In recent years, the company has actively promoted cooperation with Global Environment Limited in Hong Kong, AO Science International Technology Center in the United States, BioGill Environment in Australia, CurrentWaterTechnologies Inc. in Canada Overseas enterprises, research institutions, and universities such as Canada's Fuwei Global Procurement Co., Ltd., Australia's JieAiXi Infrastructure Engineering Co., Ltd., Sydney Institute of Technology in Australia, and Canada's Clean Energy Technology (China) Company have conducted exchanges and cooperation in areas such as atmospheric governance, sewage treatment, and odor control. The company has 26 independent intellectual property rights in the fields of deep sludge dewatering, sludge incineration power generation, and ultra-low emission control of flue gas, including 2 invention patents, 23 utility model patents, 1 software copyright, and 5 other applications for authorization. The company's core technology has been selected for the "2018 Key Environmental Protection Practical Technology List" released by the China Environmental Protection Industry Association, the "First Major Technical Equipment Promotion and Application Guidance Catalogue (2017 Edition)" issued by the Ministry of Industry and Information Technology, and the "Advanced Applicable Technology for the Construction of Waste Free Cities" Pilot Project (First Batch) selected by the Ministry of Ecology and Environment The Chinese Academy of Social Sciences and other institutions jointly released China's first "Blue Book on Ecological Governance, China Ecological Governance Development Report (2019-2020)", and participated in the Astana World Energy Expo as one of the five permanent representatives of China's new energy technology in 2017. The company is committed to the development, promotion and application of sludge treatment and disposal technology, overcoming multiple technical barriers that are difficult to overcome, and connecting the entire process from front-end modified dehydration to back-end incineration power generation. The technology of each unit is seamlessly connected, forming a full chain closed-loop technology system, realizing the conversion of sludge into energy, and solving the "last mile" problem of sludge treatment and disposal that troubles the industry. The Hebei Xinji Sludge Centralized Incineration and Power Generation Disposal Center, independently invested and constructed by the company in Xinji, Pidu, northern China, has a daily treatment capacity of 1300 tons of sludge with a moisture content of 80% and an annual power generation capacity of 86.4 million kilowatt hours. It is a typical case in the field of sludge incineration and power generation in China. The company is a national high-tech enterprise, a national technology-based small and medium-sized enterprise, a technology-based small and medium-sized enterprise in Hebei Province, a research and development institution for industrial enterprises in Hebei Province, a demonstration base for talent introduction in Hebei Province, a top ten unit for talent introduction in Hebei Province, and an international science and technology cooperation base in Hebei Province. It has passed ISO9001, ISO14001, and OHSAS18001 system certifications. The company is an executive director unit of the China Environmental Protection Industry Association, an executive director unit of the China Circular Economy Association, a vice president unit of the Hebei Environmental Protection Federation, and a member unit of the Hebei Environmental Protection Industry Association. 2、 How to carry out large-scale, high-value, resourceful disposal, and recycling of the slag after incineration of solid waste such as sludge, which is required by the proposed project technology, is a major issue that urgently needs to be solved. Hebei Guohui plans to introduce renowned 3D printing experts from the United States and jointly develop the technology of using solid waste to prepare 3D printing materials. Using urban and industrial solid waste as the main raw materials, and combining 3D printing construction technology, it aims to prepare green building materials such as non clay bricks, building blocks, building boards, and walls, in order to solve the problem of urban and industrial solid waste and provide new choices for 3D printing construction materials. The research and development, promotion and application of this project will help reduce the mining and use of natural stone materials, in line with sustainable development concepts such as creating a circular economy, building a "waste free city", and a "conservation oriented society". The main research content of this project is as follows: (1) Research on the preparation plan of green aggregates. Industrial solid waste is used as the main raw material, and different particle sizes of ceramsite sand are prepared through molding and roasting processes to replace natural river sand and other aggregates. Based on the properties and usage needs of the raw materials, different products and production processes such as expanded ceramsite, sintered ceramsite, and non fired ceramsite are developed. (2) Utilizing the previous research results, ceramsite sand, fly ash, cement Mix curing agents and other materials to prepare geopolymer cement-based materials, and combine them with 3D printing technology to form green building materials such as non clay bricks, building blocks, building boards, and walls. Adjust the preparation process, formula, and other factors to meet actual usage needs and relevant standards.
