摘要
为解决稻壳发电残余物——稻壳灰的利用问题,该文研究了稻壳灰在不同条件下对有机污染物的吸附作用。结果表明,稻壳灰在经过碱洗处理后,其对有机污染物的吸附性能明显提高。当溶液pH值小于7.0时,稻壳灰对有机污染物的吸附效果要好于pH值大于7.0时的吸附效果。该研究表明,稻壳灰经过碱洗处理后,可以用作吸附剂,吸附污水中的有机污染物,实现废物的再次利用。
Using rice husk ash as absorbent to remove organic pollutant was studied in this paper to solve the problem of the residue after power generation using rice husk.It is indicated that rice husk ash treated by alkaline cleaning was effective in removing organic pollutants.When the pH value of solution was less than 7.0,the removal effectiency of organic was better than the pH value greater than 7.0.It was proved in this study that the rice husk ash could be used as adsorbent to remove organic pollutant.
