The work period of this project is from September 9, 2020 to December 31, 2020. The progress of the work of this project is shown in Table 1, and the implementation results are as follows:
1. Monitoring of Volatile Organic Pollutants and Harmful Air Pollutants (see section 4.1 for details)
This project has completed 2 sessions of the Environmental Protection Agency’s Xingang Air Quality Monitoring Station (1 time each in autumn and winter, 2 times in total) to monitor harmful air pollutants, and analyzed 87 species of volatile organic compounds and 16 species of aldehydes. , 17 species of polycyclic aromatic hydrocarbons and 10 species of acid-base gases, etc. The first session was performed at the Environmental Protection Agency's Xingang Air Quality Monitoring Station from September 28 to September 29 to monitor harmful air pollutants. The analysis results are as follows Shown.
1. Perform monitoring and analysis of 87 species of volatile organic compounds. The analysis results show that a total of 4 species have concentrations detected, namely methanol, acetonitrile, acetone and dichloromethane. The detected concentration of dichloromethane is slightly higher than 928ppb. The emission standard of hazardous air pollutants from stationary sources (draft) has a concentration of 750 ppbv. The other 83 species are all less than the detection limit or the lowest concentration value of the laboratory calibration line.
2. Perform monitoring and analysis of 16 species of aldehyde compounds, and the analysis results of 16 species are less than the detection limit or the lowest concentration value of the laboratory calibration line.
3. Performed 17 monitoring and analysis operations for polycyclic aromatic hydrocarbons. The analysis results showed that a total of 9 species pollutants were detected, including naphthalene, acenaphthylene, acenaphthene, fluorene, phenanthrene, anthracene, phenylene, pyrene, and other species. Its species are less than the detection limit or less than the lowest concentration value of the laboratory calibration line.
4. Perform 10 monitoring and analysis tasks for acid and alkali gases, and the analysis results have a total of 1 pollutant ammonia detected, which is less than the detection limit or the lowest concentration value of the laboratory calibration line in the species.
In the second session, the monitoring of harmful air pollutants was carried out at the Xingang Air Quality Monitoring Station of the Environmental Protection Agency from December 14th to December 15th. The analysis results are shown below.
1. Perform monitoring and analysis of 87 species of volatile organic compounds. As a result of the analysis, a total of 2 species have concentrations detected, namely methanol and acetone. The other 85 species are below the detection limit or the lowest concentration of the laboratory calibration line. value.
2. Perform monitoring and analysis of 16 species of aldehyde compounds, and the analysis results of 16 species are less than the detection limit or the lowest concentration value of the laboratory calibration line.
3. Performed 17 monitoring and analysis operations for polycyclic aromatic hydrocarbons. As a result of the analysis, a total of 8 species pollutants were detected, including naphthalene, acenaphthylene, acenaphthene, fluorene, phenanthrene, anthracene, acenaphthene, and pyrene. The species are all less than the detection limit or less than the lowest concentration value of the laboratory calibration line.
4. Perform 10 monitoring and analysis tasks for acid and alkali gases, and the analysis results have a total of 1 pollutant ammonia detected, which is less than the detection limit or the lowest concentration value of the laboratory calibration line in the species.
2. Investigate unlisted factories and fuel and auxiliary fuel users (see section 4.2 for details)
The project completed a total of 154 investigations on the fuel use of unlisted factories, and a total of 95 low-pollution factory inspections and 59 unlisted (Tedden) factories were carried out. The industry types of unlisted factories in each township were other respectively. Plastic products manufacturing industry 30 plants, rubber and plastic processing machinery equipment manufacturing plants 19 plants, metal products manufacturing plants 18 plants, plastic products manufacturing plants 11 plants, plastic sheet and pipe manufacturing plants 7 plants, mechanical equipment manufacturing plants 7 plants, wood Bamboo products manufacturing plant 5, automobile and parts manufacturing plant 5, furniture manufacturing plant 4 plant, pulp and paper product manufacturing plant 3 plant, non-metallic mineral product manufacturing plant 3 plant, plastic film bag manufacturing plant 3 plant, food manufacturing plant Industry 3 factory, plastic raw material manufacturing factory 1 factory, plastic casing and accessories manufacturing factory 1 factory, printing manufacturing factory 1 factory, garment and apparel product manufacturing factory 1 factory, other chemical product manufacturing factory 1 factory, other textile product manufacturing factory 1 factory , 1 factory in other manufacturing industries, 1 factory in plastic film manufacturing, 1 factory in power equipment and equipment manufacturing, 1 factory in electronic parts assembly manufacturing, and shutdown or closure of 26 factories.
As a result of this project’s inventory, there are a total of 2 plants with combustion equipment. They are combustion equipment (boilers) used by San Oya Co., Ltd. in the food manufacturing industry. The plant is a non-tube (Tedeng) plant and the products are produced by this plant. It is a variety of bean paste fillings; after investigation, the factory has applied for the declaration of air pollution fee to this bureau, and the declaration of the most recent six months has been declared, and the declared amount is zero.
The second factory is the second factory of the furniture manufacturing Xin O Enterprise Co., Ltd. This factory is a low-pollution factory. The factory uses a drying furnace to dry the products on the iron rack. The fuel uses natural gas. The annual fuel consumption is 13,000 degrees. The factory should be put under management, but the factory has not yet applied for it. In the future, it will be entrusted to the Environmental Protection Agency for long-term follow-up control.
3. Counseling work for the control of prevention and control equipment in the catering industry (see section 4.3 for details)
A total of 135 catering industry prevention and control equipment control guidance tasks have been completed in this project. The number of villages and towns where catering industry inspection and guidance is carried out in this project is 37 in Taibao City and 35 in Puzi City, followed by 27 in Minxiong Township. , Xingang Township 24 times, Shui Township 10 times, and Liujiao Township 2 times; analysis of the installation situation of pollution prevention equipment of the inspected objects, there are only 10 gas gathering equipment companies (7.4%). There are 20 companies with baffles, filters and water curtain hoods (accounting for 14.8%), 32 companies with gas gathering equipment + pipe end equipment (23.7%); with gas gathering equipment + pre-treatment equipment There are a total of 53 companies (accounting for 39.3%) with end-of-pipe equipment; 7 companies without any control equipment (accounting for 5.2%) and a total of 13 companies closed or closed (accounting for 9.6%).
The catering industry inspection operation checked 105 catering companies that installed pre-processing equipment or end-of-pipe equipment (77.8%), 17 companies that did not install end-of-pipe equipment (accounting for 12.6%) and a total of 13 closed or closed businesses ( (Accounting for 9.6%), a total of 135 companies.
Fourth, the actual improvement of the catering industry (see section 4.4 for relevant information)
Businesses that implement actual improvement after the project counseling of this project are small-scale catering businesses or vendors. Due to the small amount of pollution and most of them are leased businesses, the space for installing anti-control equipment is limited. This plan is recommended Install simple water washing equipment, the equipment is cheaper and easy to maintain. A total of 20 catering companies have been guided by the project to install and operate the equipment, and the reductions are estimated to be 0.612 metric tons of PM10, 0.421 metric tons of PM2.5, and 2.3 metric tons of NMHC. , It is recommended that in the future when the normal plan is to carry out the catering industry audit and inspection guidance work, the catering industry should be promoted to strengthen the regular maintenance of pollution prevention equipment.
