摘要
本文讨论了沉淀法和空气提气法去除电解锰废水中含有的锰(Mn^(2+))和氨-氮(NH_3-N),并研究了该方法的最佳条件,为废水日排放量在300—400T之间的工厂设计了废水处理路线。结果表明,上述方法处理后的废水中Mn^(2+)和NH_3-N含量达到或低于国家污水排放标准。
Precipitation in conjunction with air blowing treatment for removing Mn( Ⅱ ) ions and NH3-N from the waste water in electrolytic manganese production have been discussed, and the optimal conditions have been studied. The effluent treatment line has been devised for the factory in which the effluent quantity is between 300-400 tons every day. The result show that Mn( Ⅱ )ions-and NH3-N content in the treated water is reached to or lower than the national effluent standard
