摘要
重金属在环境中不可降解且富集,会对环境造成长期危害,工业废水中重金属离子的回收成为水处理技术中的重要研究内容。本文论述了化学沉淀法、膜电解法、离子交换法与铁氧体法对工业废水中重金属离子的回收技术,对比了几种处理方式的优缺点,同时指出,将其他技术同这些技术联用,采用复合方法将成为未来工业废水中重金属离子回收的趋势。
Heavy metal in the environment cannot be degraded and easy to enrich,which would cause long-term harm to the environment,so the recycling of heavy metal ions in industrial effluent became an important research content in water treatment technology.The method of chemical precipitation,membrane electrolysis,ion-exchange and ferrite applied in recycling technology of heavy metal ions in industrial effluent were discussed.The comparison of the advantages and disadvantages among these treatment methods showed that combining these technologies and others and adopting composite method became the trend of the recycling of heavy metal ions in industrial effluent.
