摘要
Abstract
To solve the outstanding problem of"sulfonated water"pollution in metal mining area,wastewater from tailings impoundments of a metal mining area in Shaanxi province was collected and analyzed.Combining the characteristics of wastewater pollution,wastewater treatment methods and wastewater treatment economy,a reasonable treatment process was proposed.The results showed that NH3-N,COD,F-,SS,Zn and Cr6+in tailings impoundments wastewater exceeded the standard to varying degrees,but the main reason for the formation of"sulfonated water"was due to the precipitation generated by Fe3+.The treatment process of"neutralization+aeration+precipitation"was proposed,in which Fe2+reduces Cr6+to Cr3+,Fe2+is oxidized to Fe3+,and Cr3+and Fe3+are finally transformed into Cr(OH)3 precipitation and Fe(OH)3 precipitation,respectively.Metal ions such as Fe3+and Cr6+in the wastewater can be effectively removed to achieve standard discharge.关键词
