摘要
采用铁氧体法处理沉镍残液,此法处理沉镍残液效果明显。研究了pH值、温度、搅拌时间、投料比对处理效果的影响。试验结果表明：在pH=11~12,温度50℃,搅拌时间25~30 min,投料比10的操作条件下,处理后的沉镍残液中各重金属离子浓度均达到排放标准。
Ferrite process was applied to treat nickel smelter wastewater.In this way,it had evident effect for treating nickel smelter wastewater.The effects of pH,temperature,stirring time and ratio of reagent addition on the treatment were studied.The results showed that when pH =11～12,temperature is 50 ℃,stirring time is 25～30 min,and the ratio of l reagent addition is 10,the concentrations of all kinds of heavy metal ions in the effluent can meet the national discharge standards.
