Focus on R & D and manufacturing of VOCs exhaust gas treatment equipment
According to the "Integrated Emission Standard for Air Pollutants" (GB16297-1996), the sampling of fugitive emission monitoring points and reference points is generally based on the average value of a continuous one-hour sampling meter, or four samples are collected at equal intervals within one hour And count the average. 1. In the process of environmental protection daily law enforcement monitoring, are there any detailed regulations on the number of samples of fugitive waste gas collected at monitoring points? For example, a certain monitoring point must collect 3 samples, and the sampling time must be more than 3 hours to meet the requirements of environmental protection supervision monitoring? 2. If the chemical enterprises in a certain area are concentrated in one area, the enterprise and the enterprise are separated by only one wall. Because the downwind enterprises are inevitably affected by the upwind enterprises, in this case, is it unsuitable for the enterprise to arrange unmonitored exhaust gas monitoring?

1. Regarding the monitoring of daily law enforcement, it is recommended to implement the following methods or regulations. Article 37 of the "Administrative Measures for Environmental Administrative Penalties" stipulates: "The competent environmental protection department can conduct instant sampling on the spot when conducting supervision and inspection of pollutant discharge units, and the monitoring results can be used as evidence to determine whether the pollutant discharge exceeds the standard." The Interpretation of the Issues Concerning Sewage Monitoring Methods during On-site Inspections by Environmental Protection Departments (formerly the State Environmental Protection Administration Announcement No. 16 of 2007) stipulates: "The pollutant discharge methods and discharge limits specified in the emission standards are to determine the discharge behavior The technical basis for whether the standard is exceeded. At any time and under any circumstances, the pollutant discharge behavior of the polluting unit must not violate the relevant provisions in the emission standard. "" Reply to the Issue of Immediate Sampling of Environmental Administrative Penalties "(Circular Measures Regulations [2018] No. 1246) clearly: "On-site real-time sampling means that a sample can be taken for monitoring during the on-site inspection, and the monitoring result can be used as evidence to determine whether the pollutant discharge exceeds the standard. The collection of this sample must be performed in accordance with relevant technical specifications."
2. With regard to the centralized distribution of enterprises, the issue of the monitoring of enterprises' unorganized exhaust gas emissions is implemented in accordance with Appendix C3.1.1 of the Comprehensive Emission Standard for Air Pollutants (GB 16297-1996), that is, setting reference points and monitoring the downwind direction of emission sources. point.
