In China, the prospects for the development of environmental protection instruments are very bright. However, it should be noted that the foundation of environmental management in our country is relatively weak, and under the influence of insufficient capital input factors, there is a big gap between the actual needs and potential needs of the environmental protection industry, and environmental monitoring instruments are used as the basis for environmental protection. Instrumentation equipment is still far from meeting the needs of development. As China’s investment in environmental protection continues to increase, the environmental protection industry will become a new growth point for the national economy.
Environmental protection has become a global consensus, not only related to the quality of our contemporary human living space, but also related to the proliferation of human beings. China attaches great importance to the environmental protection industry and actively promotes the development of environmental protection research, including the development of environmental protection equipment.
In 2012, in the national special scientific equipment development project, 150 million yuan of central budget was allocated to support the development of environmental protection equipment and equipment. This aspect shows that the country attaches importance to the development of environmental protection instruments. On the other hand, capital investment also promotes the development of environmental protection instruments.
In addition to scientific research in environmental protection and public welfare industries, the main role of the enterprise in irreplaceable environmental protection technology innovation, scientific research organization, and application of results transformation is not irreplaceable. In fact, among the numerous scientific research projects, the participation of enterprises has been very high, and the proportion of national environmental protection technology awards that the company has led and completed has also accounted for 28%. All this shows that the company's main position in the field of environmental protection research, as well as the strength of scientific research in this field. With the continuous support of the policy for the environmental protection industry, the environmental protection industry including the development of environmental protection equipment and equipment will usher in faster development.
The environmental protection industry is a new industry that has flourished in the world in the past 20 years. It has now become a new economic growth point for some countries. The global environmental protection industry is growing at a rate of 7.5% per year, and the average annual growth rate of China's environmental protection industry is above 15%. According to statistics, the output value of China's environmental protection industry reached 1,100 billion yuan in 2010, accounting for 2.7% of GDP in the same year. There are 35,000 national environmental protection companies, 3 million people are employed, and a number of modern environmental protection companies with an annual output value of over one billion yuan have emerged. The Ministry of Environmental Protection has approved the construction of 26 key national environmental protection laboratories and 29 engineering and technical centers.
At present, the domestic urgently needed environmental protection instruments and meters mainly include: atmospheric environmental quality monitoring instruments and automatic monitoring systems; coal gas power stations or boilers as the representative of the flue gas analysis instrumentation monitoring system; surface water environmental quality testing instruments and monitoring systems; to urban sewage treatment Plants and high-concentration organic wastewater represent pollution source monitoring instruments and automatic control systems.
