Recently, the Ministry of Industry and Information Technology and the Ministry of Ecology and Environment jointly released the "Catalogue of Major Environmental Protection Technologies and Equipment Encouraged by the State for Development (2023 Edition)" (hereinafter referred to as the "Catalogue"). The "Catalogue" contains a total of 158 major environmental protection technologies and equipment in three technical stages: development, application, and promotion, covering 10 major sub-sectors such as air pollution control, water pollution control, soil pollution remediation, solid waste treatment, noise and vibration control, and environmental monitoring instruments. Lihe Technology's "Automatic Monitoring System for Ambient Air Particle Composition" was successfully selected into the promotion category of the major equipment catalogue - environmental monitoring instruments.

The formulation and release of the "Catalog" aims to accelerate the research and development and application promotion of advanced environmental protection technologies and equipment, and to improve the overall level and supply quality of the environmental protection equipment manufacturing industry. It is a comprehensive assessment by the country of the technological innovation capabilities, process technology, and promotion prospects of environmental protection technologies and equipment.

Automatic monitoring system for ambient air particulate matter composition

The automatic monitoring system for ambient air particulate matter components is developed based on standards and specifications such as the "Technical Guidelines for Particulate Matter Source Analysis". The system collects fine particulate matter (PM2.5) in the ambient air through automatic sampling devices and cutters. The detection system automatically detects the collected fine particulate matter and analyzes the content of water-soluble ions, inorganic elements and carbonaceous components (OC, EC) in the particulate matter. Combined with comprehensive analysis of regional particulate matter pollution, refined pollution analysis of urban particulate matter, dynamic pollution analysis of pollution processes and other technologies, it realizes refined analysis of the causes of atmospheric pollution.

In recent years, Lihe Technology has continuously improved its ability to monitor pollution factors in all parameters of the atmospheric environment, built and improved a nationwide technical support network, developed conventional six-parameter, ambient air particulate matter component monitoring, lidar, cruise monitoring and other automatic atmospheric monitoring systems with independent intellectual property rights, and built an integrated "air-ground-ground" atmospheric environment monitoring system; it has innovated the atmospheric pollution control and supervision service model, developed supporting data models and application software, and gradually realized the extension of "data manufacturing" to "data application", providing strong decision-making support for the precise control of urban air pollution.

In the future, Lihe Technology will take the opportunity of being selected into the "Catalogue of Major Environmental Protection Technologies and Equipment Encouraged by the State for Development" and take helping the country achieve its dual carbon goals as its starting point to continuously improve its independent innovation capabilities in atmospheric monitoring and carbon monitoring, continuously improve the level of localization of instruments and equipment, and continue to work hard to promote and apply atmospheric monitoring products and improve the national technical service network.
