| 中文摘要 |
| 城市废弃物处理是城市人为活动产生温室气体的来源之一. 参考IPCC国家温室气体清单指南2006推荐的方法建立了厦门市废弃物处理的温室气体排放计算模型,对厦门市2005~2010年废弃物处理的温室气体排放情况进行了估算,包括固体废弃物填埋、焚烧以及污水处理等过程. 结果表明,2005年温室气体总排放量折合二氧化碳当量(CO2e)为406.3 kt,2010年温室气体总排放量(以CO2e计)达到704.6 kt,随着废水处理工艺的提高和城市生活垃圾量的迅速增长,主要排放源由废水处理转变为固体废弃物填埋. 2005年填埋产生的温室气体排放占固体废弃物处理排放量的90%左右,2010年所占比例下降到75%. 厦门市废水处理温室气体排放量2007年最高,以CO2e计达到325.5 kt,化学原料及化学品制造业从2005~2010年一直是厦门市CH4排放量最高的产业,占工业废水处理CH4排放总量的55%以上. |
| 英文摘要 |
| Waste disposal is one of the sources of greenhouse gas (GHG) emissions from urban human activities. According to the method recommended by IPCC Guidelines for National Greenhouse Gas Inventories 2006, a calculation model was established to assess GHG emissions of waste disposal in Xiamen. Then GHG emissions from waste disposal in Xiamen during the year of 2005-2010 were estimated, including solid waste landfill, solid waste incineration and wastewater treatment. The results showed that total GHG emissions quantified in carbon dioxide equivalents (CO2e) from waste disposal was 406.3 kt in 2005, and increased to 704.6 kt in 2010. Because of the improvement of wastewater treatment process and rapid increasing municipal solid waste (MSW), the main source of emissions was from wastewater treatment turning to solid waste landfill. GHG emissions from solid waste landfill accounted for about 90% of total emissions from solid waste disposal process in 2005, and the proportion decreased to 75% in 2010. GHG emissions (quantified in CO2e) from waste water treatment reached the highest value 325.5 kt in 2007. Chemical raw materials and chemical industry have been the highest CH4 emission industry during 2005-2010, which accounted for more than 55% of total CH4 emission from industrial wastewater treatment. |
