选用大孔吸附树脂作吸附剂 ,氢氧化钠溶液作脱附剂 ,对水体中的胶体硅进行去除试验 ,取得了令人满意的效果 ,处理量大于 10 0倍树脂床体积 ,处理后水中的胶硅含量小于 0 .5mg/L ,符合化工生产工艺要求 ,这项技术为水处理中除胶硅技术探索了一条新途径。

They have used big-pore adsorptive resin as adsorbent and sodium hydroxide solution as desilicification agent to remove silicon colloid from the water. They have got satisfactory results. The processing capacity is 100 times larger than the resin bed volume( BV) . The silicon colloid in the water after treatment is low er than 0. 5mg/ L. It meets the requirement of the chemical technology. This technique provides a new access to the removal of silicon colloid in water treatment .
