2 Reference standard
The provisions contained in the following standards constitute provisions of this standard by reference in this standard.
GB3095-1996 Ambient Air Quality Standard
GB/T16157-1996 Determination of particulate matter in fixed pollution source exhaust gas and sampling method of gaseous pollutants

3 definition
This standard uses the following definition
3.1 Standard status
Refers to the state when the temperature is 273K and the pressure is 101325Pa. The standard values ​​specified in this standard are based on dry air under standard conditions.
3.2 Maximum allowable emission concentration
Refers to the limit of the average concentration of any 1h concentration of pollutants in the exhaust pipe after the treatment facility; or the limit of the average concentration of any 1h concentration of pollutants in the exhaust pipe of no treatment facility.
3.3 Maximum allowable emission rate (Maximum allowable emission rate)
Refers to the limit of the mass of any 1h emission of the exhaust pipe at a certain height that must not exceed the limit.
3.4 Unorganized emissions
Refers to the irregular discharge of atmospheric pollutants without passing through the exhaust pipe. Emissions from low exhaust ducts are organized emissions, but under certain conditions can also have the same consequences as unorganized emissions. Therefore, when the “unorganized emission monitoring concentration limit” indicator is implemented, the increase in monitoring point pollutant concentration caused by the low exhaust pipe is not deducted.
3.5 Unorganized emission monitoring points
A monitoring point established to determine whether unorganized emissions exceed the standard in accordance with the provisions of Appendix C of this standard.
3.6 Unorganized emission monitoring concentration limit
Refers to the concentration of pollutants at the monitoring point at any 1h average value must not exceed the limit.
3.7 Source of pollution
Refers to facilities that emit atmospheric pollutants or to building structures that emit atmospheric pollutants (such as workshops, etc.).
3.8 unit perimeter
Refers to the boundary between the unit and the external environment. Boundaries should normally be determined in accordance with legal procedures; if formalities are not established, they are determined on the basis of current actual boundaries.
3.9 Unorganized source of emissions
Refers to a facility with unorganized emissions in an open air environment, or a building structure with unorganized emissions (such as workshops, work sheds, etc.).
3.10 Exhaust cylinder height
Refers to the height from the ground plane where the exhaust cylinder (or its main building construction) is located to the outlet of the exhaust.

4 indicator system
This standard sets the following three indicators:
4.1 The maximum allowable emission concentration of pollutants discharged through the exhaust pipe.
4.2 The maximum allowable discharge rate specified by the exhaust pipe height for the pollutants discharged through the exhaust pipe.
Any one of the exhaust cylinders must comply with both of the above criteria, and any one of them exceeds the standard.
4.3 Unorganized emission of pollutants, monitoring points for unorganized emissions and corresponding monitoring concentration limits.
This indicator is implemented in accordance with the provisions of Article 9.2 of this standard.

5 emission rate standard grading
The maximum allowable emission rate stipulated in this standard is that the existing pollution sources are divided into first, second and third grades, and the new pollution sources are divided into second and third grades. According to the type of ambient air quality functional zone where the pollution source is located, the emission rate standard of the corresponding level is implemented, namely:
The pollution sources located in the first-class districts implement the first-level standard (the first-class district prohibits the new and expanded pollution sources, and the first-level standards for the implementation of existing pollution sources when the existing pollution sources are rebuilt in the first-class districts);
The pollution source located in the second-class area implements the secondary standard;
The pollution sources located in the three types of zones implement the three-level standard.

6 standard value
6.1 The pollution sources established before January 1, 1997 (hereinafter referred to as existing pollution sources) shall implement the standard values ​​listed in Table 1.
6.2 The pollution sources (including newly built, expanded and rebuilt) from January 1, 1997 (hereinafter referred to as new pollution sources) shall implement the standard values ​​listed in Table 2.
6.3 Judging the date of establishment of the pollution source according to the following regulations:
6.3.1 In general, the date of approval of the construction project environmental impact report (form) shall be the date of its establishment.
6.3.2 The pollution source established without the approval of the environmental protection administrative department shall be the date of its establishment according to the date of approval of the environmental impact report (form).

7 Other regulations
7.1 Exhaust cylinder height shall be higher than the standard value of the discharge rate in the table, and shall be higher than the surrounding area of ​​more than 5m in the radius of 200m. If the exhaust pipe cannot meet the requirements, the discharge rate shall be the standard value according to the height of the table. Strict 50% implementation.
7.2 Two exhaust pipes that discharge the same contaminant (whether or not they are produced by the same production process) shall be combined as an equivalent exhaust pipe if their distance is less than the sum of their geometric heights. If there are more than three close-range exhaust pipes and the same type of pollutants are discharged, the equivalent of the previous two exhaust pipes shall be taken in order with the third and fourth exhaust pipes. See Appendix A for the calculation of the relevant parameters of the equivalent exhaust pipe.
7.3 If the height of a venting cylinder is between the two values ​​listed in this standard, the maximum allowable discharge rate to be performed is calculated by interpolation. The calculation formula of the interpolation method is shown in Appendix B of this standard; When the height is greater than or less than the maximum or minimum value listed in this standard, the maximum allowable emission rate is calculated by extrapolation. The calculation formula of extrapolation method is shown in Appendix B of this standard.
7.4 The exhaust pipe of the new pollution source should generally not be less than 15m. If the exhaust pipe of a new pollution source must be less than 15m, the standard value of the discharge rate shall be strictly 50% according to the extrapolation calculation result of 7.3.
7.5 Unorganized emissions of new sources of pollution should be strictly controlled. Under normal circumstances, there should be no unorganized emissions. Unavoidable unorganized emissions should meet the standard values ​​specified in Table 2.
7.6 Industrial production tail gas does need to be burned and discharged, and its blackness must not exceed that of Ringman.

8 Monitoring
8.1 Distribution
8.1.1 The number of sampling points and the location of sampling points monitored by particulate matter or gaseous pollutants in the exhaust pipe shall be in accordance with GB/T16157-1996.
8.1.2 The number of sampling points (ie monitoring points) and the method of setting the sampling points for unorganized emission monitoring are detailed in Appendix C of this standard.
8.2 Sampling time and frequency
The three indicators specified in this standard refer to the limit that any 1h average value must not exceed, so it should be done at the time of sampling:
8.2.1 Sampling of exhaust gas in the exhaust pipe
The average value is obtained by sampling for 1 hour;
Or, within 1 h, 4 samples were taken at equal time intervals and averaged.
8.2.2 Sampling of unorganized emission monitoring points
Sampling for unorganized emission monitoring points and reference point monitoring, generally using a continuous 1h sampling average;
If the concentration is low, the sampling time can be extended as needed;
If the sensitivity of the analytical method is high, when only a short time is required to collect the sample, the sampling should be performed at equal intervals, and the average of the four samples should be collected.
8.2.3 Sampling time and frequency in special cases
If the discharge of a certain exhaust pipe is intermittent discharge, the discharge time is less than 1h, continuous sampling should be carried out within the discharge time period, or 2~4 samples should be collected at equal time intervals during the discharge time period, and averaged;
If the discharge of a certain exhaust pipe is intermittent, and the discharge time is greater than 1h, it shall be sampled according to the requirements of 8.2.1 during the discharge period;
When conducting pollution accident discharge monitoring, the sampling time and sampling frequency set as required are not subject to the above requirements;
The sampling time and frequency of the completion and acceptance monitoring of the environmental protection facilities of the construction project shall be implemented in accordance with the monitoring and acceptance measures for the completion of environmental protection facilities for construction projects formulated by the State Environmental Protection Administration.
8.3 Monitoring condition requirements
8.3.1 In the routine monitoring of pollution sources, the working conditions during the sampling period shall be the same as the operating conditions at that time. The personnel of the sewage disposal unit and the personnel performing the monitoring shall not arbitrarily change the operating conditions at that time.
8.3.2 Construction project The requirements for the completion and acceptance of the environmental protection facilities shall be implemented in accordance with the monitoring and acceptance measures for the completion of environmental protection facilities for construction projects formulated by the State Environmental Protection Administration.
