Environmental Monitoring Instruments: A Big Future Market

Wei Fusheng, an academician of the Chinese Academy of Engineering, said: From the country's environmental monitoring data, the deterioration of China's environmental pollution has been basically controlled, and the environmental quality has been improved, but the pollution is still at a very high level.

In the face of such severe environmental pollution and the deterioration of the ecological environment, a large number of real-time and accurate monitoring of the environmental quality, the current status of the ecological environment, and the trend of change, as well as supervision and monitoring of pollution sources and their governance, are placed on the nation’s environmental protection workers. One of the toughest tasks before it. Therefore, a large number of modern environmental monitoring instruments are urgently needed, and particularly, high-quality automatic monitoring systems and continuous on-line pollution monitoring systems are required.

The status quo and problems of environmental monitoring instruments Environmental monitoring instruments mainly include the following aspects:

(1) General-purpose laboratory analytical instruments: including optical instruments such as visible ultraviolet spectrophotometer, fluorescence photometer, atomic absorption photometer, plasma spectrometer, X-ray fluorescence spectrometer, and infrared spectrometer; electrochemical instruments such as PH meter, conductivity meter, coulometer, potentiometric titrator, ion activity meter and various polarographs; chromatographic instruments such as ion chromatography, gas chromatography, high pressure liquid chromatography, chromatography/mass spectrometry, and liquid Spectrum/mass spectrometry online and so on. Analytical laboratories should have instrumental environmental science and monitoring laboratories.

(2) Special monitoring instruments: air-TSP, PM10, MP25 samplers and their monitoring instruments (beta-ray absorption, crystal oscillator balance); gas autosamplers: SO2, NO2, NO, NOX, O3, and CO monitors; Water quality monitoring: mercury analyzer, oil meter, CODcr meter, D0 meter, sewage meter and proportional auto sampler.

(3) Automatic monitoring system: air ground automatic monitoring system; environmental water quality automatic monitoring system; industrial pollution source online continuous automatic monitoring system; road traffic noise automatic monitoring system.

The main problems of domestic environmental science monitoring instruments The number of domestically-made special monitors and samplers has an advantage and is basically available, but the added value is low. High-quality analyzers, special-purpose monitoring instruments, and automatic monitoring systems are mostly introduced from abroad, so the share of domestic instruments is very small. The reasons are as follows: First, the operational mechanism of large-scale state-owned enterprises has not played a good role in the backbone; second, small companies have flocked, lack of technology, lack of funds, and many low-level repetitions. The quality and performance of the instruments cannot be imported with foreign equipment. Third, the lack of close cooperation between research institutions and enterprises, the lack of technological innovation, and the lack of funds to achieve rapid industrialization. Fourth, the government's investment in the development of environmental science instruments and the lack of risk investment.

Future market demand for environmental science monitoring instruments (1) Environmental quality monitoring: The national environmental protection system and various departments, industries, and enterprises have established more than 4,000 monitoring stations, employing more than 60,000 employees, and tens of thousands of environmental research institutes. In recent years, it has been time for environmental science and monitoring and analysis instruments, equipment replacement and upgrading, and the central government, local governments, and companies have invested about 200 million yuan in equipment and equipment every year. The National Environmental Protection Agency plans to equip more than 400 national network monitoring stations during the "10th Five-Year Plan" period; more than 350 environmental information centers: 100 urban air ground automatic monitoring systems. The project includes: PM10, S02, N02, O3;, CO, wind direction, wind speed, temperature, and humidity; about 100 national monitoring water quality monitoring sections automatic monitoring system. The project includes PH, temperature, conductivity, turbidity, dissolved oxygen, ammonia nitrogen, total nitrogen, total phosphorus, CODcr, and permanganate index. The initial plan is to invest 1.5 billion yuan, including two-thirds of state investment and three-points of local investment. one. This does not include the investment in the capacity building of monitoring stations in industries, localities and enterprises, and various departments and localities have their own investment plans according to the needs of environmental protection tasks.

(2) Monitoring of pollution sources: The state shall implement the control and reduction of the total discharge of major pollutants to 18,000 key polluting enterprises across the country to improve the quality of the environment. Therefore, 18,000 large polluters are required to gradually install on-line continuous automatic monitoring systems. Sewage monitoring mainly includes: automatic monitoring systems for sewage flow meters, automatic proportional samplers, PH, CODcr, mineral oil, cyanide and ammonia nitrogen, and computerized network management. Exhaust gas monitoring mainly includes: On-line continuous monitoring system for industrial dust, smoke, smoke S02, N02, CO, and flue gas flow, to achieve computer networking management, and strengthen real-time monitoring, these are relatively new. There are few mature domestic instrument systems, and the demand is much greater than the environmental quality monitoring, which is mainly purchased by polluting companies. The industries are mainly electric power, petrochemicals, building materials, metallurgy, paper making, food and urban sewage treatment plants, and the potential market is from several billion to tens of billions of yuan.

(3) Remote Sensing Telemetering Instrumentation: The State proposes a principle of equal emphasis on environmental pollution prevention and ecological environment protection. To strengthen ecological environmental protection, we must monitor the ecological environment in China. Including monitoring of deserts, grasslands, forests, oceans, and agro-ecological environments, it is also necessary to carry out remote sensing telemetry of air pollution, water pollution (such as ocean red tide, oil spill pollution) and pollution sources, and to establish satellite ground receiving systems and satellite image analysis. The system analyzes the current status and changing trends of environmental ecological quality, and provides scientific basis for national environmental protection and construction.

(4) Research and Development Key Areas:

a) Automatic monitoring system for environmental quality (air, water, noise) as described above.

b) Pollution Source Emissions: On-line continuous automatic monitoring system for total discharge of sewage, waste gas and pollution sources.

c) Enhance the quality of on-site sampling and monitoring equipment and upgrade, develop and develop portable on-site pollution accident emergency monitoring equipment, research and development of mobile monitoring vehicles and monitoring vessels, and provide a modern means for rapid response to environmental pollution accidents and pollution sources monitoring and monitoring.

d) Research and development: airborne, on-board, shipboard, and satellite-borne remote sensing instrumentation, such as laser polluted radar.
