| 摘 要： | 对某矿区含砷地表水的治理技术进行了研究。首先采用氧化剂对地表水中的砷进行催化氧化,并将其与Fe Cl3生成稳定的沉淀物从水中除去;然后采用浸没式超滤—反渗透法进行治理,其浸没式超滤工艺产出水可以用于矿区生产,反渗透工艺产出水可以用于居民生活,实现了分质供水。该联合治理工艺技术在得到了合格生产用水和生活用水的同时,将地表水中的砷得到了有效治理,降低了环境污染,提高了环境效益。

| Abstract: | Research has been conducted on the treatment technology of arsenic removal from surface water in one mining area.First,oxidants were applied in order to oxidize As and then stable precipitants were obtained through re-action with FeCl3 and removed.Then,powdered active carbon/submerged ultra-filtration and reverse osmosis were ap-plied to treat the water,the product of which is qualified water for industry and households respectively,realizing a supply of different quality water.Apart from gain of qualified water for industry and households,surface water were ef-fectively treated with arsenic removed,mitigating pollution and improving environmental benefits. |
