(1) check the county hotel industry, hospitals, schools and other small and medium-sized boilers
At present, the EPD has completed all assessment projects, including checking EPD's designated list, social welfare agencies, inventory control of schools, subsidy promotion briefing sessions and counseling for the replacement of low-pollution fuel boilers. This project has achieved full marks. As a result of the inventory, 9 of the 80 designated lists of EPDs were duplicated and six were discontinued. Two new lists of non-EPDs were added, covering a total of 114 boilers (77 for diesel, 25 for heavy oil and 12 for solar or electricity), schools, A total of 176 hospitals and social welfare agencies have installed 46 boilers for a total of 86 vehicles (61 for diesel oil, 3 for heavy oil, 21 for solar or electric power and 1 for gas); expansion of subsidies for lodging, military police and corrective agencies Social Welfare Institutions 11, a total of 22 boilers (two heavy oil, diesel 18, electric energy 2).
Boiler replacement results, a total of 14, are replaced by heat pump. Completed the conversion and applied for eight grants (four heavy oil and four diesel oil) to the Environmental Protection Department for application for the replacement of six (diesel) applications.
(2) Detecting PM2.5 from fixed pollution source and establishing fingerprint data
The project has completed three test and analysis operations of PTPEP (P002), Taiwan Cement Heping Factory (P206) and Zhonghua Pulp Hualien Factory (P003). The test results, test results and FPM measured values were 10.8, 4.2 and 12.2 mg / Nm3 respectively, and the CPM values were 10.2, 8.9 and 384.4 mg / Nm3, respectively, of which CPM measured by Zhonghua Pulp and Hualian Factory was higher than that of FPM 32 times, component analysis CPM contains a large number of Cl ions, CPM anion and cation analysis showed higher Cl ions, presumably with the chlorate process (M03) output of thenardite solution related to the other relevant literature also pointed out that the current Notice that the CPM sampling method may be overestimated.For the emission factor, the cement plant in Taiwan is 130 g / mt for coal, 41 mpg for coal-fired power plants and 51 g / mt for China Hualian Pulp Mill. The emission factor is higher than that of the previous years. With reference to the same industries measured in other counties and cities, the measured value of TGP Peace Factory falls into the range of measured value of each cement industry in Ilan. The measured value of Peaceful Power Plant is higher than that of Taichung Thermal Power Plant and the previous years , Hualian Pulp and Paper Factory, due to the same process less testing data, and only 105 years of measured value comparison, it is recommended follow-up monitoring to improve the reliability of the test value.
In the part of fingerprint database, the main components of filterability PM2.5 in Taiwan Cement and Healing Plant are TC, Ca2 +, SO42-, Cl- and NO3- respectively. The main components of PM2.5 in Hepingli Power Plant are TC, SO42-, Mg2 +, F- and Cl-. The main constituents of PM2.5 in Chinese Hualian pulp plant are SO42-, TC, Na +, K + and NH4 +.
(3) to analyze the sources of pollutants of the EPD's own air quality monitoring station (Hualien Station)
Using ISCST3 to simulate the pollution sources within 10 km around Hualien County station, the contribution of each pollution source was compared with 98.5% of PM2.524 hour as index, of which fixed source accounted for 7.99%, mobile source accounted for 11.78% and evapotranspiration accounted for 19.92 The other 60% contributed to the overseas transmission, pollution sources beyond ten kilometers, derived secondary pollution or sources of pollution (such as sea salt droplets) that have not yet been grasped. The contribution of native primary pollutants, TSP contributes the largest fugitive dust, followed by the catering industry, plant management, construction sites and vehicle emissions. Compared with the 105-year average monitoring results of the stations, the PM10 still contributed the highest dust to the automobile manufacturers, accounting for about 11%, followed by the catering industry, accounting for 6.93% and the emissions from highway vehicles being 3.66%, contributing nearly 3% . PM2.524hours 98% contribution of high value contribution, the simulation results in the restaurant industry contributed 14.6%, followed by highway vehicles (6.15%) and the vehicle dust (5.35%), the total contribution of about 11.5%, the overall contribution of fixed sources of pollution 6.1%. SO2 contributed the highest 16.6% to the plant management, followed by the other 5%, including residential and commercial combustion. NO2 contributed about 52% of the total road vehicles to the highest, followed by those in charge of factories and Yisu sources, contributing about 5% respectively. NMHC contributed the largest number of road vehicles, followed by the catering industry, followed by the tube factory.
(4) analysis of the contribution of particulate matter emissions PM2.5 contribution to the formation of PM2.5
According to the month-by-month concentration analysis of grid-mode CMAQ simulation, the average concentration of PM2.5 in non-event days is 28.2 g / m3, of which the contribution concentration of local primary emissions is about 22 g / m3. Derivative emissions The contribution of local emissions falls below 70% while the contribution from local pollution still falls within the range of 0.2 to 3.0 g / m3. However, the measured concentrations at the stations caused by local pollution can still meet the current air quality standards for fine suspended particulates within 24 hours. The concentrations of simulated PM2.5 were 57.3 g / m3 and 60.9 g / m3 on December 10 and December 27, respectively, of which the long-term transmission could contribute to the PM2.5 concentration of up to At 45 g / m3, accounting for 80% of the total concentration, the impact of other counties and cities on Hualien County is relatively low, about 0.5-2 g / m3 (1-2%). The contribution of Hualien local emissions, And derivative respectively 1 g / m3 and below 10 g / m3, accounting for 18 to 19%.The estimation of PM2.5 emissions from TEDS 9.0 is reviewed, including: 1. The ratio of contaminated sources of particulate matter is examined, of which the proportion of mines is significantly overestimated. Therefore, the survey results of the sampling project of Hualien County are revised and the revised total emissions An amount of 1,554 metric tons / year is approximately 719 metric tons less per year than the TEDS 9.0 announcement. 2. Wind erosion area of the mine The total area of the TEDS mining area was 13,107.6 hectares obtained by Fa Wen Mineral Bureau with the mining area of 1,104.9 hectares, only 8% of the total area. 3. Analysis of emission factors of diesel vehicles in Hualien County found that the base emission rate of diesel vehicles used in Hualien County is smaller than that of actual ones, resulting in underestimation of emissions of various pollutants. 4. Using the VD data released by the Highway Administration to conduct provincial road traffic flow monitoring and analysis and the monitoring results of the traffic flow of small vehicles with the largest flow from Yilan to Taiwan in line 9 on the 9th line, , Taiwan 11 and Taiwan 11 C, the trend of large car traffic flow to Hualien urban Taiwan and Taiwan 11 9 as the main flow of vehicles focused on the route, the number of miles compared to TEDS9.0 estimated activity intensity is still Within reasonable limits 5. Ship Emissions Push Results TEDS 9.0 mining source estimation was set at near-surface discharge. However, the actual emission was released through flue and was modeled for ship combustion emissions in the port area.
To investigate the causes of high concentration event day in Hualien station background. In December 102 Hualian station on December 10 and 27, two high concentration event days were observed. The concentrations of PM2.5 in the entire eastern region, the offshore region, and even the western region were all observed High, it is obviously affected by the transmission from outside China.
This project proposes the main pollution source control strategies and reduction targets. The control strategy reduces the effectiveness of pollutants estimated TSP reduction of 1,263 tonnes, PM10 reduction of 670 tonnes, PM2.5 reduction of 295 tonnes, SOx reduction of 45 tonnes, NOx reduction of 526 tonnes, NMHC reduction 96 metric tons.
