【摘要】 根据实测数据和理论分析,提出砖瓦厂烟囱的排氟量与烧砖时氟的释放量之比的计算概念,求得单位砖产的最大排氟量约为文献值的1/5.3,由此表明:在杭嘉湖蚕桑区内,砖瓦和水泥两产业的最大排氟量大致相近,对大气氟污染同居于支配地位,故对两者应取并举的治氟方针。更多还原

【Abstract】 On the basis of measured data and theoretical analyses,a concept for calculating the ratio of the fluorine exhausted by the brick-kiln chimney to that released during brick-baking is presented,by which the maximum chim- ney exhaust per unit brick-output is found to be about 1/5.3 of the literature value,showing that,in areas of silkworm breeding(Hang-Jia-Hu),the maxi- mum fluorine exhaust by the brick industry is about the same as that by the cement industry,both being serious sourses of air pollution that should be properly harnessed.更多还原
