长期饮用高砷水有害人体健康 ,而改饮低砷水可以缓解已发病者的症状。研究经济、高效、简便的饮水除砷剂是十分必要的。本课题研制的强化除砷剂具有除砷容量高 ,出水的含砷量低于 0 0 5mg L ;除砷功能专一 ,即只除去水中的砷而不改变水中其它元素的组成和含量 ;操作管理简单 ,进水、出水均无需调节pH ;除砷成本低 ,每吨成本仅为活性氧化铝或颗粒活性炭的 1 5 ,氧化催化剂可重复使用。有望广泛用于高砷水地区集中式和分散式供水的除砷系统。
Long-term consumption of high-arsenic water is harmful to human health, and drinking low-arsenic water can relieve the symptoms of those who have been ill. It is very necessary to study economical, efficient and convenient drinking water to remove arsenic. The developed arsenic removal agent has the advantages of high arsenic removal capacity and arsenic content of less than 0 0 5 mg L in the effluent. The arsenic removal function is specific, that is, it only removes arsenic from the water without changing the composition and content of other elements in the water. Simple management, no need to adjust the pH value for water and effluent, low cost of arsenic removal, 15% cost per ton of activated alumina or granular activated carbon, oxidation catalyst reusable. It is expected to be widely used to remove arsenic in centralized and decentralized water supply in high-arsenic water areas.
