广东某垃圾焚烧厂PM_(2.5)水溶性离子特征分析

Characteristics of Water Soluble Ions in PM_(2.5) of A Waste Incineration Plant in Guangdong

垃圾焚烧厂的燃烧尾气一直困扰着附近居民的生活,燃烧尾气中PM_(2.5)对人体危害极大,对PM_(2.5)中水溶性离子检测分析是必要的。2016年4-6月,在广东某垃圾焚烧厂工作时间进行样品采集。在垃圾焚烧厂设立3个采样点,分别为下风向500 m,下风向1000 m,下风向1500 m,共3个采样点,进行PM_(2.5)样品采集。采用离子色谱法测定样品中水溶性无机离子,分析其主要组分、污染来源及主要离子的相关性。

The combustion exhaust gas of the waste incineration plant has been plaguing the lives of the nearby residents,and the PM2.5in the exhaust gas is very harmful to the human body. It is necessary to detect and analyze the water-soluble ions in PM2.5. In 2016,April to June,sample collection was done in working hours of a garbage incineration plant in Guangdong. 3 sampling points were set up in the incinerator,500meters below the wind direction,1000meters downwind,1500m eters downwind,PM2.5 samples were collected in a total of 3 sampling points. The watersoluble inorganic ions in the samples were determined by ion chromatography. The main components,the sources of pollution and the correlation of major ions were analyzed.
