杭嘉湖蚕桑区主要大气氟污染源及治理现状

Abstract

Abstract: 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 brickklin exhaust gas can be reduced to less than 5mgm-3 with RST so that airborne fluoride pollution to sericulture ecosystem can be limited within 300m from pollution source.

Key words: brickkiln, airborne fluoride, treatment, efficiency
