碱性工业废水在燃煤锅炉烟气脱硫中的应用

摘要

阐述了碱性工业废水脱硫的机理以及p H值、液气比、进气SO2浓度等对脱硫效率的影响。利用碱性工业废水对燃煤锅炉烟气脱硫，其脱硫效率平均可达70%～80%。%This paper describes in brief the desulphurizati on mechanism of alkaline industrial wastewater and the effect of pH value, q/l r atio,initial SO2 concentration on DeSO2 efficiency Applying alkaline industr ial wastewater in flue gas desulphurization from coalfired boiler,the aver age DeSO2 efficiency reaches 70%～80%.
