高温焙烧改性底泥吸附剂的应用
Application of high temperature roasting modified sediment adsorbent
摘要
Abstract
In the dredging process of the battery produced a lot of sediment,and the amount of accumulation is increasing. Not only to the destruction of the ecological environment,but also take up a lot of land. At present,the comprehensive utilization of sediment in Dianchi has been preliminarily explored,But how to achieve the reduction of sediment,harmless,stable disposal and resource utilization,is a big problem to be solved. In order to solve this problem,a new method is put forward,which uses sediment as adsorbent. In order to solve this problem,it is proposed that the sediment is used as adsorbent to adsorb heavy metal ions in industrial wastewater,which provides a new way to realize the resource utilization of sediment. Through the high temperature calcination treatment sediment adsorption treatment of chromium and copper containing wastewater, using static adsorption method. The effects of calcination temperature, pH, ion concentration, adsorption temperature and adsorption time on the adsorption of Cr6+ and Cu2+ were studied. The results show that the treatment of wastewater containing chromium and copper by high temperature roasting sediment has the advantages of high removal rate, high adsorption capacity and good treatment effect. The results of thermodynamic parameters show that the adsorption process of Cr6+ and Cu2+ is spontaneous, endothermic and entropy.关键词
