摘　　要：文章对钢铁、水泥、电力、化工行业典型节能技术、过程控制、末端治理技改措施协同性进行分析,研究结果显示:各技改措施在减污降碳方面均存在一定的协同效应,源头节能措施正协同效应显著,末端治理往往呈现出负协同效应,节能效果明显的技改措施,C0_(2)相较于SO_(2)、N0_(x)具有更高的减排效应。不同类型技改措施协同度呈现出源头节能技术〉过程控制技术>末端治理技术的趋势,治理措施越向末端倾斜,产生的协同减排效果越弱。企业在选择技改方案时:垃圾协同处置可成为水泥、电力行业重要的节能减排路径,精细化管控和能源回收利用可成为化工行业有效推进减污降碳的优选途径。整体上节能技改的正协同效应明显,仍是企业开展大气污染物治理和温室气体管控的成本最小化的重要技改路径。This study analyzes the synergy of typical energy-saving technologies,process control and end treatment technical transformation measures in iron and steel,cement,electric power and chemical industries.The research results showed that:all technical transformation measures have certain synergistic effectsin reducing pollution and carbon emission.The positive synergistic effect of source energy-saving measures is significant,and the end treatment often shows negative synergistic effect.For technical transformation measures with obvious energy-saving effect,CO2 has higher emission reduction effect than SO_(2) and NO_(x).The synergy degree of different types of technological transformation measures showed that the source energy-saving technology>process control technology>end treatment technology.The treatment measures are more inclined to the end,the synergistic emission reduction effect is weaker.When enterprises choose technical transformation schemes:Waste collaborative disposal can become an important path to cement and power industries,and fine management and control and energy recycling can become the preferred way for the chemical industry.On the whole,the positive synergistic effect of energy-saving technological transformation is obvious,and it is still an important technological transformation path for enterprises to minimize the cost of air pollutant control and greenhouse gas control.
