铁屑还原－鼓风氧化－石灰凝沉法脱除硫酸生产废水中的砷

Removal of Arsenic Contained in wastewater from Sulphuric Acid Production by Iron Cuts Reduction-Air Oxidation-Lime Coagulation Process

比较了硫酸生产废水的几种除砷方法，认为铁屑还原－鼓风氧化－石灰凝沉工艺是可行的，此法具有处理量大、处理效果好、运行费用低等优点。

By comparision of some processes for recovering arsenic contained in wastewaterfrom sulpburic acid production,it is considered that iron cuts reduction-air oxidation-limecoagulation process is practicable with the advantages of higher capability,better efficiencyand lower cost.
