粉煤灰基絮凝剂对垃圾渗滤液中铜离子的吸附作用研究

Study on adsorption of coal ash coagulant on Cu²⁺ in waste leachate

摘要: 利用粉煤灰和废旧铝皮在一定条件下反应,制得粉煤灰基絮凝剂,进而处理垃圾渗滤液中的铜离子。实验结果表明,粉煤灰基絮凝剂对垃圾渗滤液中的铜离子有较好的去除效果。在粉煤灰基絮凝剂用量5g、吸附时间2.5h、垃圾渗滤液浓度10mg/L(Cu²⁺)、吸附温度35℃、垃圾渗滤液pH为8.5的条件下,粉煤灰基絮凝剂对垃圾渗滤液中铜离子的去除率达72.1%,比普通粉煤灰的去除率提高134.1%。

Abstract: Coal ash and waste aluminum were used to produce coal ash coagulant under a certain condition.The experiment result showed that coal ash coagulant can remove Cu²⁺ in waste leachate effectively. Under the best condition,the removal rate of coal ash coagulant on Cu²⁺ in waste leachate was 72.1%.It was 134.1% higher than the common coal ash.
