摘要
以氢氧化镁作为水处理剂处理含铜酸性废水。考察了氢氧化镁用量、搅拌时间、温度及pH对处理效果的影响。结果表明:氢氧化镁对含铜污水的处理,操作简便、去除率高,可达99%以上。氢氧化镁回收后,经轻烧处理变成氧化镁,仍可以多次用来处理含铜废水,去除率可达98%以上。
The treatment of wastewater containing copper ion using a water treatment reagent of magnesium hydroxide was studied. The effect of magnesium hydroxide dose, stirring time, temperature and pH value were examined.The results indicate that magnesium hydroxide has an excellent performance including easy operation, super removing rate, the removal rate of copper in wastewater reaches more than 99 %, etc. Furthermore, the used magnesium hydroxide still can be used to treat wastewater repeatedly with a better effectiveness when it is changed into magnesium oxide in high temperature ,the removal rate of copper reaches more than 98%.
