摘要
随着人民生活水平的逐年提高、物质消费的增长,垃圾和废水产生量和处理量也逐年增多,随之而来的也是处理过程中温室气体排放量的增长。废弃物是一种重要的可再生能源资源,控制废弃物处理温室气体排放具有较好的环境和社会效益。结合《IPCC国家温室气体清单指南》中的核算方法,建立适合杭州市实际情况的废弃物处理温室气体排放量核算模型,核算杭州市废弃物处理温室气体排放情况,分析排放特征,摸清主要排放源及主要污染物种类。结果显示,2005~2015年废弃物温室气体排放量在2011年后得到一定控制,但总体呈上升趋势,其中排放量最大的排放源为填埋处理和工业废水处理温室气体排放,最大的排放气体为CH_4。
With the improvement of people＇s living standards and the material consumption, discharge and capacity of waste and waste water increased significantly. Waste is an important renewable energy resource, and controlling GHG emission from waste treatment had good environmental and social benefits. Combined with methods in IPCC Guideline for National GHG Inventories, this study established calculation model suitable for the current situation of Hangzhou, calculated GHG emission, analyzed the emission characteristics, found out the main emission sources and main pollutants. The results showed that during 2005 - 2015, GHS emission from waste treatment had been controlled after 2011, but the overall trend was on the rise, of which the largest emissions were from landfill treatment and industrial wastewater treatment, the largest emission gas is CH.
