氧化锌法吸收低浓度SO_2烟气技术的工业化应用

Industrial Application of Technology of Using Zinc Oxide Method to Abosorb low-concentration SO_2 Fume

指出工业上产生的低浓度SO2废气是一种对大气污染最为严重的污染源,故治理SO2烟气污染的技术,已成为环保研究的重要课题。阐述了采用锌冶炼的中间产品作为吸收剂的氧化锌法,是一种可以吸收铅锌冶炼厂产生的低浓度SO2烟气,使气体达标排放、吸收渣返回生产流程再生的清洁生产工艺。

The paper points out that lowconcentration SO2 waste gas produced in the industrial production is one of the most serious pollutant sources for air pollution and how to prevent and control SO2 gas pollution has already been a key task for environmental protection research.It is discussed that zinc oxide method with intermediate product of zinc smelter as absorbent is a clean production process that can absorb lowconcentration SO2 fume from a lead and zinc smelter so as to make th SO2 fume reach the standard of gas discharge and make the absorption residue returned to the process flow for regeneration.
