Emission standard of cooking fume in catering industry

Legal analysis: 1. Catering service units shall set up permanent inspection holes, sampling platforms and sewage outlet signs at the exhaust port. 2. The sampling position of lampblack and non-methane total hydrocarbon is the same, so it should be selected in the vertical pipe section, avoiding the flue elbow and the parts with drastic cross section changes. The sampling position shall be set at a position not less than 3 times the diameter from the downstream direction of elbow and reducer and not less than 1.5 times the diameter from the upstream direction of the above components. For rectangular flue, its equivalent diameter d=2ab/(a+b), where a and b are side lengths. 3. When the cross-sectional area of the exhaust pipe is less than 0.5m2, the sampling point is taken as the dynamic pressure median; When the cross-sectional area exceeds the above, the number of sampling points shall be determined according to gb/t 16 157 and hj/t 397. 4. When the catering service unit monitors the emission of lampblack and non-methane total hydrocarbons, it shall take samples during the peak hours of its cooking operations (cooking, food processing or other operations that produce lampblack). The sampling times are three consecutive sampling times, and each sampling time is 10 minute.

Legal basis: People's Republic of China (PRC) Environmental Protection Law.

Article 40 The State promotes clean production and recycling of resources.

Relevant departments of the State Council and local people's governments at all levels shall take measures to promote the production and use of clean energy.

Enterprises should give priority to the use of clean energy, adopt technologies and equipment with high resource utilization rate and low pollutant discharge, as well as technologies for comprehensive utilization of wastes and harmless treatment of pollutants to reduce the generation of pollutants.

Forty-first facilities for pollution prevention and control in construction projects shall be designed, constructed and put into use at the same time as the main project. Facilities for the prevention and control of pollution shall meet the requirements of the approved environmental impact assessment documents, and shall not be dismantled or left idle without authorization.

Article 42 Enterprises, institutions and other producers and operators that discharge pollutants shall take measures to prevent and control environmental pollution and harm caused by waste gas, waste water, waste residue, medical waste, dust, malodorous gas, radioactive substances, noise, vibration, light radiation and electromagnetic radiation generated in production, construction or other activities.

Enterprises and institutions that discharge pollutants shall establish a responsibility system for environmental protection, and clarify the responsibilities of the person in charge of the unit and relevant personnel.

Key pollutant discharge units shall install and use monitoring equipment in accordance with relevant state regulations and monitoring norms, ensure the normal operation of monitoring equipment, and keep original monitoring records.

It is strictly prohibited to illegally discharge pollutants through concealed pipes, seepage wells, seepage pits, perfusion or tampering with or forging monitoring data, or through the abnormal operation of pollution prevention facilities to avoid supervision.
