The group standard "Technical Requirements for Semiconductor-Grade Ozone Generators" has been officially released and implemented.

2026-01-08

On December 9, 2025, the first group standard in China’s semiconductor industry—“Technical Requirements for Semiconductor-Grade Ozone Generators” (T/CIET 1946-2025)—led by Guolin Semiconductor was officially released and put into effect. The development of this standard promotes the standardized development of the industry, drives technological innovation and supply-chain collaboration, and provides a scientific and quantifiable basis for the selection and application of ozone equipment in the semiconductor and panel-display industries.

CECS group standard "Ozone Catalytic Oxidation Sewage Treatment Technical Regulations" compilation group was established and the first working meeting was held

2021-06-30

On June 9, the China Engineering Construction Standardization Association's group standard "Technical Regulations for Ozone Catalytic Oxidation Sewage Treatment" was established and the first working meeting was held in China Municipal Engineering North China Design and Research Institute Co., Ltd. (South Institute). The meeting was presided over by Dr. Li Chunju, Secretary General of the Urban Water Supply and Drainage Professional Committee of the China Engineering Construction Standardization Association, the focal point of the standard, and a team of 6 industry experts headed by Li Shuyuan, a national survey and design master from the Central South Design and Research Institute of China Municipal Engineering, was invited to come and guide. For the preparation of this standard, the Municipal North China Institute invited 14 enterprises and institutions with extensive professionalism and regional representation, including Tianjin Wanfeng, Qingdao Guolin, and Anhui Huaqi, to participate in the drafting of the standard, of which our company was the first to participate in the compilation. unit. During the meeting, the relevant industry expert team and members of the preparation group discussed and communicated on the preparation outline, and the industry expert team highly affirmed the necessity and practical significance of the preparation standard. Ozone catalytic oxidation wastewater treatment technology is currently one of the best treatment methods to complete the upgrading and transformation of various wastewater treatment plants. Although it has been popularized and applied, it is still in process design, installation and commissioning, operation and maintenance management and selection of supporting devices. In a state of no rules and no basis, the scientificity and rationality of the design data of each project and the standardization of the use of the technology are still lacking. Through the formulation of the group target, it can be standardized, rationalized, and developed scientifically and soundly.

The national heavy project "coal-fired boiler pollutant integrated control technology research and engineering demonstration" ozone equipment was successfully accepted

2021-06-15

On May 27, 2021, experts from 6 universities including the High-Tech Center of the Ministry of Science and Technology, Tsinghua University, and 2 companies including Huaneng Group demonstrated the national key R&D program "Integrated Control Technology for Coal-Fired Boilers" in Xiangyuan The device was inspected on site. Our customer service staff accompanied the expert group to visit the project to ensure the normal operation of the ozone device system. The ozone system of this project has been guiding the installation and commissioning since March. Under the circumstances of short construction period, heavy tasks and high requirements, the on-site engineers worked overtime to fully cooperate with the progress of the project, and played the role of Guolin people's "service first, customer first" the spirit of. In the end, the task was successfully completed under the premise of ensuring quality and quantity. On April 23, the ozone device system was successfully turned on and put into use. As the core equipment of the "multi-pollutant integrated control device", Guolin's ozone system plays a vital role in the desulfurization and denitrification of waste gas. In the context of the 14th Five-Year Plan, which aims to reduce pollution and reduce carbon emissions, the successful acceptance of this project has not only improved the competitiveness and influence of National Forestry, but also contributed to the realization of the national energy conservation and emission reduction goals, and promoted the development of a green economy. Quality development!
