To detect whether there still have PM2.5 compound contamination on the condition of dedust equipment through the study.Both qualitative and quantitative analysis on the multiple contaminants and the particle radius of the sample were done by using chemical and electron microscope, electron spectrum, GC-MS, etc.The ingredient of the compound contamination: H2O 22%, organics 34.75%, inorganics 43.75%. Main inorganics were Cu, C, Pb, Al, and most of their radiusor = 1.1 microm. There were over 140 kinds of organics, mainly the hydroxybenzene and PAHs. Besides heavy metals such as Pb, As, inorganics also included arsenic acid and phosphoric acid.On the existing condition of existing dedust equipment, the compound contamination in aerosol of metallurgical plant were multiple kinds of heavy metals, acidic oxide and tens of kinds of organic contaminations (hydroxybenzene and PAHs), and their radiusor = 1.1 microm. |
