  The emission control of air pollutants in the cooking process of catering service units in Beijing is also applicable to the emission control of air pollutants by food manufacturing enterprises that produce oil fume emissions
This standard is not applicable to the emission control of air pollutants from household cooking During catering inspection, not only oil fume inspection, but also noise inspection and oil sewage discharge inspection shall be carried out
These three items are all necessary items
Catering service unit: , Enterprises, institutions and other operators providing catering services for social life, mainly including: , （1） Catering service organization （2） Operating catering departments in hotels, hotels, resorts and other places （3） It is located in the canteen of institutions, social organizations, private non enterprise units, enterprises and other units that provide centralized dining for internal employees and students （4） Kitchen and other group meal processing service institutions
Oil fume emission standard: , DB11 / 1488-2018 test items of air pollutant emission standard for catering industry: , (1) Oil fume: , (2) Particulate matter: , (3) Distribution point of non methane total hydrocarbon oil fume: , According to the number of groups to be distributed by the oil fume purifier, how many groups of oil fume need to be distributed by several oil fume purifiers? Sampling times: , Once a year, the allowable emission concentration of air pollutants is as follows: , Unit: mg / M & sup3 No
allowable emission concentration of pollutant project , 1 oil fume 1
0 , 2 particulate matter 5
0 , 3 total non methane hydrocarbons 10
0 , Note: the allowable emission concentration refers to any concentration less than the average concentration in 1 hour and shall not exceed Note: the allowable emission concentration refers to any concentration less than the average concentration in 1 hour and shall not exceed Sampling location: , The sampling location shall be preferentially selected in the vertical pipe section
Avoid the flue elbow and sharp change of section
The sampling position shall be set at the place not less than 3 times the diameter from the downstream direction of the elbow and reducer, and not less than 1
5 times the diameter from the upstream direction of the above components
For the rectangular flue, its equivalent diameter d = 2Ab / (a + b), where a and B are the side length
Sampling point: , When the cross-sectional area of the exhaust pipe is less than 0
5 square meters, take the middle value of dynamic pressure; If it exceeds the above cross-sectional area, it shall be carried out in accordance with the relevant provisions of GB / T 16157-1996
Sampling requirements: , When monitoring the emission of air pollutants from catering service units, the sampling period shall be placed in the operation period or cooking operation period
