燃煤电厂氟污染与治理对策

本文以一个包含干湿两种除尘系统的高氟煤源的电厂为例，研究了电厂的氟迁移转化规律和氟污染源对周围环境的影响。并提出了综合治理电厂氟污染的对策。研究表明：湿法除尘系统的氟污染物主要是渣氟、水氟，而干法除尘系统主要是渣氟和气氟；小麦氟含量与大气中氟显著相关；灰场附近的地表水受到灰水的氟污染，部分潜水井受到了灰场渗水的污染，部分灰场土壤受到大气氟污染。

Study on Fluorine Pollution and its Control Counter measure to Power Plant Burning Coal

This paper analyzes the regularity of power plant's fluorine migration & transformation and the influence of fluorine pollution source on environment through taking one power plant burning high fluorine coal for example, which contains two systems of dry and wet method to remove dust and puts forward some counter-measures to control comprehensively power plant's fluorine pollution. The results indicate that fluorine pollution of the system removing dust by wet method was mainly from dregs & water fluorine and the system of dry method was from dregs & gas fluorine. The fluorine concentration of wheat was very obviously related to fluorine concentration of the atmosphere. The surface water near the ash field was polluted by fluorine of ash-water and some phreatic water was polluted by fluorine of permeating water from ash-field. Some ash-field soil was polluted by fluorine from atmosphere.
