/L,Zn 305 mg/L。我公司原來處理含砷污酸采用一級硫化、石灰—鐵鹽二段中和法處理工藝,運行過程中發(fā)現(xiàn)諸多弊端很難滿足環(huán)保要求。 mg/L,因此,含砷污酸的治理日益引起人們的重視。 neutralization slag在銅精礦還原熔煉過程中,精礦中所含的砷有90%以上以氣態(tài)As2O3形式揮發(fā)進入煙氣和煙塵中。 wastewater。關鍵詞:砷;污酸;污水;優(yōu)化;中和渣中圖分類號:X703;TF811 文獻標志碼:A 文章編號:10077545(2013)06000000Process Optimization of Waste Acid and Wastewater in Copper SmeltingXU Yan(Hangzhou Fuchun River Smelting Limited Company, Hangzhou 311401, China)Abstract:The processes to treat waste acid and wastewater in blister copper smelting were optimized. The processes to harmlessly discharge high arsenicbearing waste acid and wastewater and to neutralize slag were put forward. The high arsenicbearing waste acid and wastewater can be harmlessly discharged after process optimization.Key words:arsenic。doi:銅冶煉污酸污水處理工藝流程的優(yōu)化徐焰(杭州富春江冶煉有限公司
