摘要
福建省某矿山露天采场矿坑废水采用曝气氧化、初沉淀、pH调整、催化氧化、絮凝沉淀、接触氧化、机械浓缩过滤的废水处理工艺,分别处理含Cd 0.455,Mn 233.4,Cu 1.725,Zn 455.7 mg/L,p H 2.5的超标废水,实践得到出水分别含Cd 0.018,Mn 0.018,Cu 0.024,Zn 0.005 mg/L,p H6.81,符合一级水排放标准。
We know a certain mine in Fujian province in open pit mine is applied in wastewater aeration oxidation, including precipitation,pH adjustment,catalytic oxidation,flocculation precipitation,contact oxidation and the process of mechanical enrichment in filter wastewater treatment.The process contains Cd 0.455 mg/L,Mn 233.4 mg/L,1.725 mg/L Cu and zinc pH 2.5 455.7 mg/L,the excessive wastewater.Practice is to get out of the water containing Cd 0.018 mg/L,Mn 0.018 mg/L,0.024 mg/L Cu,zinc pH 6.81 0.005 mg/L,and it conforms the level of water discharge standards.
