甘肃省主要污染物排放现状及减排对策研究

Main Pollutant Discharge Status and Research on Emission Reduction Countermeasures in Gansu Province

以甘肃省近3年生态环境统计数据为基础,通过采用综合对比、趋势分析等方法,分析了甘肃省污染物排放现状。结果表明:废水污染物主要由农业源和生活源排放,废气污染物主要由工业源、生活源和机动车排放。“十四五”前期在各项减排措施的实施下,减排工作取得了一定的成效,近3年工业源、生活源、机动车主要污染物排放量都有一定程度的减少。并分析了当前减排工作存在的问题,提出了下一步工作建议,包括深化工业源氮氧化物深度治理、加强机动车污染防治、加强农业源减排项目实施、持续推进生活源减排项目建设及探索开展排污权交易工作。

Based on the ecological and environmental statistics of Gansu Province in recent 3 years,this paper analyzed the pollutant discharge status of Gansu Province by comprehensive comparison and trend analysis.The results show that the waste water pollutants are mainly discharged by agricultural sources and domestic sources,and the waste gas pollutants are mainly discharged by industrial sources,domestic sources and motor vehicles.The analysis shows that under the implementation of various emission reduction countermeasures in the early period of the 14th Five-Year Plan,the emission reduction work has achieved certain results,and the emissions of major pollutants from industrial sources,domestic sources and motor vehicles have been reduced to a certain extent in the past three years.The problems existing in the current emission reduction work are analyzed,and suggestions for the next step are put forward,including deepening the in-depth treatment of nitrogen oxides from industrial sources,strengthening the prevention and control of motor vehicle pollution,strengthening the implementation of emission reduction projects from agricultural sources,continuously promoting the construction of emission reduction projects from domestic sources,and exploring the implementation of emission rights trading.
