摘要
对杭嘉湖蚕桑区大气氟主要污染源——砖瓦厂氟的排放状况及各种含氟烟道废气治理装置的治理效果进行了较为深入的调查分析,认为砖瓦厂含氟废气不经烟道排放较为严重。目前砖瓦厂所采用的各种含氟废气治理装置中,旋流板塔装置除氟效率较佳,可使废气氟的排放浓度降至5mg/m^3以下,基本上能消除下风向300m以远的大气氟污染对蚕桑的严重危害。
In this paper, the main airborne fluoride sources, emitted from widely distributed brickkilns, and their pollution characteristics in Hangjianhu Sericulture District of Zhejiang Province are deeply investigated and analyzed. Many treatment devices have been used to reduce fluoride concentration in brickkiln exhaust gas. Rotating-stream Trag (RST) is one of the best devices with high fluoride removing efficiency. Fluoride concentration in brick-klin exhaust gas can be reduced to less than 5mgm-3 with RST so that airborne fluoride pollution to sericulture e-cosystem can be limited within 300m from pollution source.
