【摘要】 本文以赤泥为主要原料,在高温下将赤泥加热使之脱水,从而产生大量的孔隙,利用赤泥中孔隙对污水溶液中COD(化学耗氧量)的吸附作用进行研究。实验表明:赤泥对有机废液具有一定的吸附性,并且随着煅烧温度的升高,吸附效果逐渐提高。在400℃煅烧的赤泥,其吸附效率只有7%,而当煅烧温度提高到1000℃时,赤泥的吸附效率可提高到38.7%。该方法对处理赤泥、保护环境具有重要意义。更多还原

【Abstract】 In this paper red mud produced some pores after being heated and the pore can absorb some organic compound in waste water.The results showed that the treated red mud did absorb a certain quantity organic compound,and the capability of adsorption enhanced as the increasing temperature.When red mud was heated at 400℃,the absorbed organic compound is 7%;while the heating temperature reached to 1000℃,the absorbed organic compound was 38.7%.So it was very important for this method to treat red mud and protect the environment.更多还原
