【摘要】:近年來,我國以京津冀地區(qū)為代表的經(jīng)濟(jì)發(fā)達(dá)地區(qū)灰霾天氣頻發(fā)。隨著電力需求的逐年增加,京津冀火電行業(yè)煤耗逐年上升,所排放的污染物是造成京津冀地區(qū)大氣污染的重要因素。因此,研究京津冀地區(qū)火電行業(yè)污染物的排放特征及其對大氣污染的貢獻(xiàn),可以為火電機(jī)組進(jìn)行結(jié)構(gòu)調(diào)整、節(jié)能減排以及進(jìn)行大氣污染防治工作提供理論基礎(chǔ)。本文基于2013年京津冀地區(qū)火電機(jī)組大氣污染物排放清單,對京津冀地區(qū)燃煤電廠空間分布、裝機(jī)結(jié)構(gòu)、各污染物排放等特征進(jìn)行分析;采用WRF-CALPUFF模式模擬并分析了 2013年京津冀地區(qū)的灰霾污染特征及其影響因素;評估了各季節(jié)火電排放對京津冀地區(qū)污染物濃度的貢獻(xiàn);預(yù)測了火電機(jī)組進(jìn)行結(jié)構(gòu)調(diào)整及執(zhí)行不同的污染物排放限值后灰霾污染的改善程度。研究表明,京津冀地區(qū)火電裝機(jī)受地形影響分布較為集中,天津、石家莊、唐山、邯鄲4市的裝機(jī)臺數(shù)、裝機(jī)容量、煤耗量、各污染物排放量的加和分別超過了京津冀總量的50%,單位發(fā)電標(biāo)煤耗、污染物排放濃度與裝機(jī)容量分布呈反向關(guān)系。2013年京津冀地區(qū)PM2.5濃度時空分布主要受地形及氣象要素影響,重污染區(qū)域主要集中在臨太行山及燕山山脈的平原地區(qū)。2013年京津冀火電排放對平原地區(qū)的PM2.5濃度貢獻(xiàn)值要高于山區(qū)區(qū)域,對山區(qū)的PM2.5濃度貢獻(xiàn)率卻要高于平原地區(qū),整個模擬時段火電排放對北京市城區(qū)PM2.5濃度的平均貢獻(xiàn)率為12.1%;痣姍C(jī)組分別執(zhí)行特別排放限值及超低排放的污染物排放限值后,京津冀地區(qū)PM2.5濃度下降較為明顯,且污染越嚴(yán)重的區(qū)域其下降幅度越大,整個模擬時段火電排放對北京市城區(qū)PM2.5濃度的平均貢獻(xiàn)率分別下降到了 7.25%與5.93%。
[Abstract]:In recent years, frequent in Beijing Tianjin Hebei region as the representative of the developed area of our country haze. With the increase of electricity demand year by year, coal consumption in Beijing, Tianjin and Hebei thermal power industry has increased year by year. The pollutants emitted are the important factors that cause atmospheric pollution in Beijing, Tianjin and Hebei. Therefore, the study of pollutant emission characteristics and contribution to air pollution in thermal power industry of Beijing Tianjin Hebei region can provide theoretical basis for structural adjustment, energy saving and emission reduction and air pollution prevention and control for thermal power units. The atmospheric pollutant emission inventory in 2013 in Beijing Tianjin Hebei region based on thermal power units in coal-fired power plants, space distribution, the Beijing Tianjin Hebei region installed structure, pollutant emission characteristics were analyzed; simulation and analysis of haze pollution in 2013 of the Beijing Tianjin Hebei region and its influence factors staining feature using WRF-CALPUFF model; assessment of seasonal thermal power emission of pollutant concentration of Beijing and Tianjin Hebei contribution; prediction of thermal power units to carry out structural adjustment and implementation of different pollutant emission limit to improve the degree of haze pollution value. Research shows that the thermal power installed in Beijing Tianjin Hebei region affected by terrain distribution is more concentrated, Tianjin, Shijiazhuang, Tangshan, Handan City, 4 units, installed capacity, coal consumption, emissions of pollutants and more than 50% of the total units of Beijing Tianjin Hebei, power generation standard coal consumption, pollutant concentration and installed the inverse of the volume distribution. In 2013, the temporal and spatial distribution of PM2.5 concentration in Beijing Tianjin Hebei region was mainly affected by topography and meteorological factors. Heavy pollution areas were mainly concentrated in plain areas which were in Taihang Mountain and Yanshan mountains. In 2013, the contribution of Beijing Tianjin Hebei thermal power to PM2.5 concentration in plain area was higher than that in mountain area. The contribution rate to PM2.5 concentration in mountainous area was higher than that in plain area. The average contribution rate of thermal power discharge to PM2.5 concentration in Beijing city was 12.1% during the whole simulation period. Thermal power units are the implementation of the special emission limits and ultra low emission emission limits, the concentration of PM2.5 in Beijing Tianjin Hebei region decreased obviously, and the more serious the pollution of the area decreased, the average contribution of thermal emission simulation period in Beijing city PM2.5 concentration rate decreased to 7.25% and 5.93%.
