Description

一种铜铁改性性活性炭吸附剂
技术领域
本发明属于吸附剂技术领域，具体涉及一种铜铁改性活性炭吸附剂。
背景技术
随着城市化进程的加快、城市人口的增加以及环保意识的加强，城市工业废水与生活污水的排放量日益增多，城市污水处理率也逐年提高，污水厂的污泥产生率也急剧增加。废水中的污染物结构复杂，难以生化降解，排放到环境中会对生态产生毒害作用，严重威胁到人类的健康。
目前，废水处理的方法有高级氧化法、膜处理法、吸附法等。其中高级氧化法除去效率高、速度快，但容易造成二次污染；膜处理法成本较高；吸附法操作简单、投资小，尤其对低浓度的污染物优势明显，利用吸附法去除水体中难降解有机污染物的研究收到了广泛关注。
活性炭是多孔吸附材料，具有丰富的孔隙结构、较高的比表面积以及很强的吸附能力。近年来广泛应用于净化空气、除臭、脱色、污水处理等，需求量增加。但是活性炭处理不能达到理想效果，处理后活性炭分离困难，往往需对其进行改性。
发明内容
本发明的目的在于针对现有技术的不足，现提供一种重复利用性能强、吸附效果好、易分离的铜铁改性活性炭吸附剂。
为解决上述技术问题，本发明采用的技术方案为：一种铜铁改性活性炭吸附剂，其创新点在于：按重量份计，包括如下组分：硝酸铜5-10份、硝酸铁10-20份、活性炭30-50份、蒸馏水50-100份、二氧化硅5-10份、盐酸1-5份、蒙脱石5-10份、沸石5-10份、高岭土5-10份、聚乙二醇3-5份。
进一步的，所述硝酸铜与硝酸铁的重量比为1：1.5-3。
本发明的有益效果如下：本发明利用铜铁改性活性炭，使活性炭具有磁性，经吸附处理后能够通过磁场将其分离，分离效果迅速，操作简单，且经分离之后的活性炭再生后能够再次投入废水处理中，重复利用性强，效果稳定，减少了活性炭的成本；本发明活性炭比表面积大、吸附效果好、吸附能力、成本低，具有较好的市场运用前景。
