摘　　要：在工业园区的烟囱中,由于难以到达烟囱顶部,因此,很难直接测量烟囱排放的颗粒物(particulate matters,PM)。本研究在无人机(unmanned aerialvehicle,UAV)上部署了自主研发的PM检测器,直接测量纺织印染工业园区烟囱烟羽中PM的排放。与商用PM检测装置(LD-5R,SIBATA,日本京都)相比,自主研发的探测器在无人机上同时进行垂直PM测量时表现出相似的性能,并具有良好的相关性(R2为0.911~0.951)。在静电沉淀后,颜料印花中不同尺寸的颗粒物质量浓度和颗粒物数量浓度(particle numberconcentrations,PNC)显著高于染色工艺和数码印花2到3倍。活性炭吸附和静电沉淀是园区主要的PM控制技术。染色工艺的排放经活性炭吸附后,PM质量浓度和PNC含量最高,PM1、PM_(2.5)和PM10的浓度分别为1027μg/m^(3)、1637μg/m^(3)和2020μg/m^(3)。根据PM和PNC的检测结果发现,PM_(2.5)是PM排放的主要颗粒物,占比达到99%,这可能是由于热固机温度过高,有利于PM_(2.5)的产生。本研究显示,PM_(2.5)是纺织印染企业减少PM污染而需要减少的主要颗粒物。Directly measuring particulate matters(PM)from chimneys in an industrial park is difficult due to the difficulty of reach⁃ing the top of the chimneys heights.A self-developed PM detector on an unmanned aerial vehicle(UAV)was deployed to directly measure the PM emissions in smoke plumes from chimneys in a textile dyeing industrial park.Compared with a commercial PM device(LD-5R,SIBATA,Kyoto,Japan),the self-developed detector showed similar performance with a good correlation(R2 varying from 0.911 to 0.951)in simultaneously vertical PM measurements on UAV.The PM emissions from chimneys after different textile treating processes,including pigment printing,dyeing process,and digital printing,were investigated.PM mass concentrations and particle number concentrations(PNC)in different sizes were significantly higher in pigment printing than those in dyeing process and digital printing by 2 or 3 times after electrostatic precipitation.The activated carbon adsorption and electrostatic precipitation were the major PM controlling techniques in the park.The PM mass concentrations and PNC were the highest in the process of dye⁃ing after activated carbon adsorption with the concentrations of PM1(1027μg/m^(3)),PM_(2.5)(1637μg/m^(3)),and PM10(2020μg/m^(3)),respectively.According to the results of PM and PNC,PM_(2.5)the dominant particles accounting for 99%of the PM emissions.It may be due to the high temperature in thermo-fixing machine,which is beneficial to the PM_(2.5)generation.This study revealed that PM_(2.5)was the dominant particles to be reduced in textile dyeing enterprises to mitigate PM pollution.
