GB/T3840--91
This standard specifies the methods for formulating local emission standards for air pollutants. This standard is applicable to guide provinces, autonomous regions, municipalities directly under the Central Government and their subordinate areas in formulating emission standards for air pollutants. 2 Reference standards

GB9137 Maximum allowable concentration of air pollutants for protecting cropsTJ36 Design hygienic standards for industrial enterprises
3 General provisions
3.1 This standard is formulated to implement the Environmental Protection Law of the People's Republic of China and the Law of the People's Republic of China on the Prevention and Control of Air Pollution. 3.2 This standard is a method standard to guide the formulation and revision of local air pollutant emission standards. 3.34 The standard takes the atmospheric gas base standard as the control standard, and on the basis of the diffusion and dilution law of air pollutants, uses the method of controlling air pollution by using the total emission allowable limit value of the control area (defined in Article 4.1) and the point source emission allowable limit value. In addition, local areas can also formulate local air pollutant emission standards based on local technical and economic conditions, and apply the best feasible and best practical technical methods or other total control methods.
3.4 The emission limits of pollutants listed in the air pollutant emission standards formulated by all provinces, autonomous regions and municipalities shall not be lower than the emission limits calculated by this standard and the limits of relevant national air pollutant emission standards. 3.5 The provisions of this standard have equal effect under the same conditions, but when the allowable emission limits determined in various provisions of the same pollution source standard are inconsistent, the minimum allowable emission limit shall prevail. 3.6 The provisions of the provisions in this standard are for reference when using this standard. 4 Total emission control areas for gaseous air pollutants and atmospheric environment functional zoning 4.1 Total emission control areas for gaseous air pollutants (hereinafter referred to as total emission control areas) are areas where local people's governments decide to implement total emission control on air pollutants according to urban planning, economic development and environmental protection requirements. Areas outside the total emission control areas are called non-total emission control areas, such as the vast rural areas and remote and wasteland areas with low industrialization levels. For areas with acid rain hazards, total emission control areas for SO2, NOx and NO2 should be set up as much as possible.
4.2 Atmospheric environment functional zones are areas of the country where different social functions are required for environmental protection. The number of functional zones is unlimited, but they should be divided into Class I, Class II and Class III by local people's governments according to relevant national regulations and urban and rural master plans. They correspond to the three types of air quality zones in GB3095.
Approved by the State Environmental Protection Agency on August 31, 1991 and implemented on June 1, 1992
GB/T3810-91
Class I zones: natural reserves, scenic spots, sanatoriums, etc. specified by the state. Class II zones: residential areas, mixed commercial and transportation residential areas, cultural areas, scenic spots and historic sites, and vast rural areas determined in urban planning. Class III zones: towns and industrial areas with relatively heavy air pollution, as well as urban transportation hubs and trunk lines. 4.3 Both total amount control areas and non-total amount control areas can be divided into functional areas according to Article 4.2. 4.4 The concentration limits of atmospheric pollutants in each functional area in this standard are determined in accordance with GB3095. For pollutants with concentration values specified in this standard, they are determined according to the allowable concentration limits for residential areas in GB36; the concentration limits for crop protection areas are determined according to the concentration limits specified in GB9137. 5 Method for formulating emission standards for gaseous atmospheric pollutants generated in the process of fuel combustion Gaseous atmospheric pollutants generated in the process of fuel combustion refer to pollutants generated by the combustion of various mineral fuels by various energy-producing equipment, such as suspended dust, carbon dioxide, nitrogen oxides and carbon monoxide, referred to as atmospheric pollutants in this chapter. 5.1 Method for calculating the total amount limit of atmospheric pollutant emissions in the total amount control area 5.1.1 The limit of the total amount of pollutant emissions in the total amount control area is calculated by formula (1): Qk

This standard only specifies the allowable concentration limit for atmospheric pollutants. Generally, it can be taken as three times of the monthly average tolerable concentration limit. For substances that cause visible phenomena, such as mercury, lead, etc., their average tolerable concentration limit can be taken directly. 6.2.2 The emission coefficient R is taken from Table 1 based on the type of the region where the exhaust gas is located, the type of the atmospheric environment quality functional zone and the height of the exhaust pipe.

Harmful gases that do not pass through exhaust pipes or through air passages below 5m in height are all considered unorganized emissions. Industrial enterprises should use reasonable production process flow, strengthen production management and equipment maintenance, and minimize the unorganized emission of harmful gases. 7.2 When the concentration of harmful gases emitted from unorganized sources exceeds the annual concentration limit specified in G33695 and 36, the production barrier (inside the production area) where the unorganized emission source is located shall be equipped with a biosafety protection distance of 100m; when it exceeds 100m, the level difference is 200m; when it exceeds 1000m, the level difference is 200m. 7.4 The sanitary protection distance of various industries and enterprises shall be calculated as follows: N0 r

Solution: The emission of harmful substances coexisting with unorganized emission sources is not sensitive to the emission of harmful substances. The standard stipulates that the emission of harmful substances coexisting with unorganized emission sources is not allowed to coexist with the emission of harmful substances in the atmosphere. The tolerance index of harmful substances in unorganized emission is the technical acute reaction index to determine the material. The three-no-organized emission tolerance index is determined by the overall investment reaction index. The production process is reasonable, the production management and equipment maintenance are at the advanced level of industrial enterprises, and the unorganized emission during normal operation is selected. When the value calculated by formula (31) is between two levels, the wider level is selected. 7.5 For industrial enterprises that emit more harmful gases, the required sanitary protection distance shall be calculated based on the maximum value of QC; when the sanitary protection distance calculated based on the QC value of one or more harmful gases is at the same level, the upper level of the sanitary protection distance of such industrial enterprises shall be increased by one level.
7.6 The required sanitary protection distance for industrial enterprises located in complex terrain conditions shall be jointly determined by the competent department of the construction unit and the main environmental protection department of the province, autonomous region where the construction project is located based on the environmental impact assessment report. 8 Formulation of smoke emission standards Determination method

Solution: Coexisting with unorganized sources of harmful gases, the non-toxic and allergic reactions of the manufacturers are very important! The standard stipulates that the allowable emission is one-third of the emission of various atmospheric pollutants that can coexist with the emission of other gases from organized emission sources, and the allowable emission index of three non-organized hazardous substances is determined by the technical and acute reaction index. The unorganized emissions during normal operation are selected from industrial enterprises with reasonable production process flow, advanced production management and equipment maintenance. When the value calculated by formula (31) is between two levels, the wider level is selected. 7.5 For industrial enterprises that emit more harmful gases, the required sanitary protection distance shall be calculated based on the maximum value of QC; when the sanitary protection distance calculated based on the QC value of one or more harmful gases is at the same level, the upper level of the sanitary protection distance of such industrial enterprises shall be increased by one level.
7.6 The required sanitary protection distance for industrial enterprises located in complex terrain conditions shall be jointly determined by the competent department of the construction unit and the main environmental protection department of the province, autonomous region where the construction project is located based on the environmental impact assessment report. 8 Formulation of smoke emission standards Determination method
