摘要
以氢氧化镁作为吸附剂处理含镉酸性废水 .结果表明 ,氢氧化镁对Cd2 +的吸附为化学吸附 ,去除率一般可达 98%以上 .氢氧化镁回收后 ,经轻烧处理变成氧化镁 ,仍可以处理含镉废水 。
The treatment of wastewater containing cadmium ion using a water treatment reagent of Mg(OH) 2 was studied,and the mechanism and effect conditions of the treatment was examined.The results indicate that Mg(OH) 2 has an excellent performance including easy operation,super removing rate etc.In the treatment of wastewater,and this method is easy up to national standard.The removing rate 98% was achieved.Furthermore,the used Mg(OH) 2 still can be used to treat wastewater repeatedly with a better effcetiveness when it was changed into MgO in high temperature.
