Industrial civilization and urban development, while creating enormous wealth for human beings, also discharge billions of tons of exhaust gas and waste into the atmosphere. The atmosphere on which human beings live depends on air dumps and gas storages. When harmful gases and pollutants in the atmosphere reach a certain concentration, they will cause great disasters to humans and the environment. Therefore, environmental monitoring and environmental governance are imminent.
Here we look at an example:
The Sanmenxia City Environmental Monitoring Station of Henan Province received a notice from the Environmental Monitoring Center of Henan Province regarding the acceptance monitoring of Yima Kaixiang Chemical. Kaixiang Chemical is currently in the trial production phase. Henan Environmental Protection Bureau will use this monitoring result to determine whether the company meets the acceptance criteria.
Sanmenxia City Environmental Monitoring Station 13 staff in accordance with the division of labor began to monitor in Kaixiang Chemical. The engineer led the monitoring staff to collect the wastewater samples and collected the samples 4 times a day for 3 consecutive days. Sample collection of 6 exhaust gas items.
Eight points were set in the chemical plant area. The monitoring staff held up the tripod and took out the atmospheric sample collector. In just ten minutes, four instruments were installed and the sample collection started. The factors to be collected by the staff are wind direction, atmospheric pressure, hydrogen sulfide ( hydrogen sulfide detector ) , and methanol. Each sample is collected for one hour.
In addition to human monitoring, environmental monitoring also includes an environmental quality automatic monitoring system. The ambient air quality automatic monitoring system can continuously monitor the ambient air quality for 24 hours. The system consists of a monitoring center station, a monitoring station, and a quality assurance laboratory. The air environment monitoring substation includes a sampling system, a gas analysis instrument, a calibration device, a meteorological system, and substation data collection. The data monitored by the substation is sent to the Environmental Monitoring Center via a telephone line for real-time control, data management and graph generation.
In the environmental monitoring industry , as an indispensable monitoring instrument, China also urgently needs to increase technical investment and innovation in the scientific research of monitoring instrumentation to adapt to the trend of high automation and intelligence in the future.
