Key developments in environmental monitoring equipment 1, air and exhaust gas monitoring equipment:
(1) Pollution source The dust (dust) on-line monitor is used to monitor pollution source dust, process dust emissions (concentration or total amount) online, including measurement related parameters: flow, O2, moisture content, temperature, etc. The necessary monitoring equipment for monitoring.
(2) Flue gas SO2, NOx on-line monitoring instrument is used to monitor the content of SO2 and NOx in the flue gas on-line. Through the flow measurement, total amount monitoring can be realized.
(3) Automatic Monitoring System of Ambient Air This system is used for weekly and daily air quality monitoring. The main monitoring items are: SO2, NOx, CO, O3, PM10, etc.
(4) Acid rain automatic sampler automatically collects precipitation samples to determine the pH of precipitation.
(5) The PM10 sampler is used to collect particles with an aerodynamic equivalent diameter of 10 μm or less in ambient air.
(6) Fixed and portable vehicle exhaust gas monitor is used to determine the content of CH, CO, etc. in exhaust gas of motor vehicles.
2. Pollution sources and environmental water quality monitoring instruments:
(1) On-line monitoring of pollution sources The total amount of pollutants emitted from the monitoring equipment requires simultaneous monitoring of concentration and flow. On-line flow measurement and proportional sampling are the basic technical measures for total monitoring. On-line monitoring equipment is also required for key pollution sources.
(2) Flowmeters are used to standardize the on-line continuous monitoring equipment for the sewage discharge flow of open channels.
(3) The automatic sampler is used for the online automatic sampling device which has the flow rate proportion and the time ratio of the pollution source discharge port.
(4) On-line monitoring instruments On-line measurement and analysis instruments for industrial pollution sources or sewage outlets. The main monitoring items include: COD, TOC, UV, NH4, NO3-N, cyanide, volatile phenol, mineral oil, pH, etc. It should have automatic calibration and automatic flushing piping functions.
(5) Automatic monitoring equipment for environmental water quality Automatic online monitoring equipment for surface water environmental quality indicators. The automatic water quality monitoring project is divided into five general parameters of water quality and other items. The five parameters of water quality include temperature, pH, dissolved oxygen (DO), conductivity, and turbidity. Other items include permanganate index and total organic carbon (TOC). , total nitrogen (TN), total phosphorus (TP) and ammonia nitrogen (NH3-N).
(6) Total organic carbon (TOC) The total organic carbon (TOC) is an indicator of organic matter content in the reaction water and can be used for the monitoring of pollution sources or surface water.
3, Portable on-site emergency monitoring equipment Portable on-site emergency monitoring equipment for sudden environmental pollution accident monitoring, its main features are small, easy to carry and fast monitoring.
(1) Portable spectrophotometer Portable spectrophotometer for on-site monitoring. The test components generally include toxic items such as cyanide, ammonia nitrogen, phenols, aniline, arsenic, mercury and antimony.
(2) Small toxic and harmful gas monitor Small portable instrument used for on-site monitoring of toxic and harmful gases. The main monitoring items include CO, Cl2, H2S, SO2, and combustible gas monitoring.
(3) Simple and rapid detection tube is used for rapid quantitative or semi-quantitative detection of hazardous components in water or air. It is mainly used for monitoring items including CO, Cl2, H2S, SO2, combustible gas, ammonia nitrogen, phenol, hexavalent chromium, and fluorine. , sulfides and COD.
4. Electromagnetic radiation and radioactivity monitoring instruments (1) Omnidirectional broadband field strength meter is used to measure the integrated electromagnetic field strength in a certain frequency range.
(2) Spectrum analyzers are used to measure the field strength and spectral distribution of electromagnetic radiation at different frequencies.
(3) Power frequency field intensity meter is used to measure 50HZ power frequency electromagnetic field intensity.
(4) Large-area screen ionization chamber alpha spectrometer measures the concentration of alpha radionuclides in environmental media.
(5) Whole body counters are used to monitor the systemic contamination of professional workers or the public.
(6) Environmental radiation dose rate meter is used to monitor the environmental penetration radiation level.
