5.1 Sewage unit emissions (including leakage and unorganized For odor pollutants emitted), the maximum monitoring value (including odor concentration) at the specified monitoring point (without other interference factors) at the boundary of the sewage unit must be lower than or equal to the factory boundary standard value of odor pollutants. 5.2 The emission volume and odor concentration of odorous pollutants emitted by sewage discharge units through smoke and gas exhaust pipes (height above 15m) must be lower than or equal to the odorous pollutant emission standards.
5.3 The odor pollutants and odor concentration discharged and emitted by the sewage discharge unit through drainage must be lower than or equal to the factory boundary standard value of odor pollutants, 6 Monitoring
6.1 Organized emission source monitoring||tt ||6.1.1 The minimum height of the exhaust pipe shall not be less than 15m. 6.1.2 For exhaust pipes between the two heights listed in Table 2, the rounding method is used to calculate the height of the exhaust pipe. The exhaust pipe height listed in Table 2 refers to the vertical height from the ground (zero ground) to the exhaust port. 775 | | tt | | GB14554-93 | The lower part is sampled and monitored to measure the odor concentration or convert it to obtain the actual emissions. The monitoring point of the treated pollution source is located at the exhaust outlet of the treatment device, and a permanent sign should be set. 6.1.4 The sampling frequency of organized emission sources should be determined according to the production cycle. If the production cycle is within 8 hours, the sampling frequency will be every 2 hours. If the production cycle is greater than 8 hours, the monitoring frequency will be collected once every 4 hours. The maximum measured value will be used. 6.2 Unorganized emission source monitoring
6.2.1 Sampling points
The monitoring sampling points at the factory boundary should be set on the downwind side of the factory boundary, or on the boundary line in the direction of odor. 6.2.2 Sampling frequency
Continuous emission sources are sampled every 2 hours, for a total of 4 times, and the maximum measured value is taken. For intermittent emission sources, sampling is selected during the maximum odor time, and the number of sample collection times is no less than 3 times, and the maximum measured value is taken. 6.3 Water area monitoring
Water area monitoring (including oceans, rivers, lakes, drainage ditches, canals) should use the shore as the factory boundary line, and its sampling point setting and sampling frequency are the same as those for unorganized emission source monitoring.

6.1.3 Sampling point: The monitoring sampling point of the organized emission source should be the exhaust port where the odor enters the atmosphere. It can also be sampled and monitored at the horizontal exhaust duct and the lower part of the exhaust pipe to measure the odor concentration or convert it to obtain the actual emission. The monitoring point of the treated pollution source is set at the exhaust port of the treatment device and a permanent sign should be set. 6.1.4 The sampling frequency of the organized emission source should be determined according to the production cycle. If the production cycle is within 8 hours, the sampling should be once every 2 hours. If the production cycle is greater than 8 hours, the sampling should be once every 4 hours. The maximum measured value is taken. 6.2 Monitoring of unorganized emission sources
6.2.1 Sampling points
The monitoring sampling points at the factory boundary are set on the downwind side of the factory boundary or on the boundary line where the odor is located. 6.2.2 Sampling frequency
The continuous emission source is sampled once every 2 hours, for a total of 4 times, and the maximum measured value is taken. The intermittent emission source is selected to sample during the maximum odor time, and the number of sample collection times is not less than 3 times, and the maximum measured value is taken. 6.3 Water area monitoring
The monitoring of water areas (including oceans, rivers, lakes, drainage ditches, and canals) should use the shore as the factory boundary line, and the sampling point setting and sampling frequency are the same as those for monitoring unorganized emission sources.
