水泥行业是我国一次颗粒物排放控制的重点,分析水泥行业颗粒物排放现状和减排潜力对改善我国以颗粒物为特征的大气污染问题具有重要意义.基于排放系数法,以2014年为基础年,研究全国水泥行业颗粒物排放现状,首次详细测算了水泥行业颗粒物无组织排放量,分析了水泥行业颗粒物排放地域分布特征;并利用情景分析的方法,预测从水泥生产全生命周期的角度考虑采取控制措施,2020年颗粒物减排潜力.研究结果表明,2014年我国水泥行业颗粒物排放总量为196万吨,有组织排放量与无组织排放量相当,颗粒物排放地域差异显著.根据我国“十三五”社会经济发展预期和现有相关产业政策和规划,2020年水泥和熟料产量将比2014年分别增长12%和7%,颗粒物排放总量将相应增长10%左右.水泥工业大气污染物排放新标准(GB4915-2013)的实施可减少颗粒物有组织排放量约40%,从源头控制、过程管理、末端治理等方面采取综合措施,颗粒物排放总量可削减41%.
