On-line continuous monitoring of emission concentrations and total emissions from fixed sources of contaminants was achieved by the flue gas on-line monitoring equipment using extraction sampling, backscatter ash concentration measurement, leather hosting smoke flow measurement and computer network communication technology. At the same time, technical improvements have been made in response to the country ' s relatively small coal species, high variations in coal, high discharge concentrations of pollutants and high flue gas humidity. The Chinese operating platform and the Chinese reporting function, multi-group simulations and switch input output interface, which are provided in accordance with standard design specifications, allow for connectivity to the on-site bus and the choice of multiple communication methods to allow the system to operate in a flexible manner.

The VOC online monitoring equipment consists of pre-treatment units, gas analysis and data processing display transmissions in three major parts. The system uses intelligent, high performance gas sensors, which are easy to install, measure accuracy, reliability, speed of response and high intervention resistance. The monitoring of toxic gases, such as workshop, plant and stationary source alarms, is widely applicable.

Frozen on-line monitoring analyzers meet the measurement and gas drying requirements for all critical parameters. It is so tightly structured that it can be transported in small cars, thus saving the cost of trucks. The instruments and accessories are light enough to be carried and operated by one person. It's very small and can easily be put in difficult places and save you time and money. Despite the tight structure, there is room for future additions to the measurement function.

In the analysis of atmospheric pollution, there is always an overemphasis on objective conditions and disadvantages. Compared with other cities, such as topography, wind direction, location, the perception that the lack of improvement in environmental quality is largely due to external causes, and that some prefer to talk about input pollution rather than to analyze underlying causes and not to strengthen themselves, is very detrimental to environmental pollution management.

The harm caused by atmospheric pollution includes, inter alia, impacts on the climate and the atmospheric environment, as well as threats to the survival of flora and fauna. The atmospheric environment is an important component of the natural environment, and atmospheric pollution will lead directly to the deterioration of the Earth ' s climatic conditions and living environment. As the process of industrialization accelerates, the impact of human activities on the atmosphere becomes more severe, and climate change resulting from atmospheric pollution is already evident.

The total hydrocarbons and the total hydrocarbons and the gas chromatography methods, respectively, are non-methane hydrocarbons. Methods I and II use gas chromatographs to determine the concentration of total and methane hydrocarbons in air, respectively, the difference being non-Methane hydrocarbons; method III uses GDX-102 and TDX-01 to adsorpt samples of air at constant temperatures, non-Methane hydrocarbons are adsorbed with sampling tubes, heat-resorption is followed, gas chromatographs are imported, determined by flame ionization detectors, and the results are calculated as perpentane. chromatography of gas chromatography in the emissions of fixed sources of pollution
