大亚湾石化工业园区环境空气调查及控制策略探究

通过对大亚湾石化工业园区环境空气质量进行调查和分析,根据细颗粒物(PM_(2.5))、可吸入颗粒物(PM_(10))、二氧化硫(SO_(2))、二氧化氮(NO_(2))、一氧化碳(CO)和臭氧(O_(3))6项基本空气污染物指标的月均浓度、年均浓度,研究探讨了2018—2022年大亚湾石化工业园区3个站点主要污染物随时间的变化情况。对2022年的检测数据进行分析,结果表明:2022年大亚湾石化工业园区空气污染主要以PM_(2.5)为主,综合污染指数有上升的趋势。其中,PM_(2.5),PM_(10),SO_(2),NO_(2),CO均呈现出冬季高、夏季低的特点;O_(3)呈现冬季低、夏季高的特点。根据污染的现状分析了产生这些污染物的原因,并提出了工业园区的污染控制策略和建议。

This paper investigated and analyzed the ambient air quality of Daya Bay Petrochemical Industrial Park,and based on the monthly and annual average concentrations of six basic air pollutant indicators:fine particulate matter(PM_(2.5)),inhalable particulate matter(PM_(10)),sulfur dioxide(SO_(2)),nitrogen dioxide(NO_(2)),carbon monoxide(CO)and ozone(O_(3)),this paper analyzes and discusses the change of major pollutants in three sites of Daya Bay Petrochemical Industrial Park from 2018 to 2022.The analysis of the test data in 2022 shows that the air pollution in the industrial park in 2022 is mainly PM_(2.5),and the comprehensive pollution index has a rising trend.PM_(2.5),PM_(10),SO_(2),NO_(2) and CO are all high in winter and low in summer.O_(3) is low in winter and high in summer.According to the current situation of pollution,the causes of these pollutants are analyzed,and the control strategies and suggestions for industrial parks are put forward.
