Description

一种活性炭吸附剂
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。污水处理厂的污泥含水率高，有大量的有机物、有毒有害物质等的具有复杂流变性的半干性固体废物，它容量大、易腐败、不稳定、有恶臭，如不妥善处理，将带来严重的环境污染。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。活性炭的原材料主要是煤和木材等含碳材料，成本较高，污泥中含有大量的有机物，具有被加工成含碳吸附剂的客观条件，利用污泥热解法制备活性炭活性炭，不仅能获得廉价的活性炭，将污泥中可溶性重金属转化成难溶物固定在活性炭中，从而减少对环境的污染，还可以将污泥活性炭运用于污水处理、空调净化、脱色、有毒有害物质等处理。但是活性炭成本较高，制约着活性炭的推广应用。
发明内容
本发明的目的在于针对现有技术的不足，现提供一种比表面积大、吸附性能好、原料廉价易得的新型活性炭吸附剂。
为解决上述技术问题，本发明采用的技术方案为：一种活性炭吸附剂，其创新点在于：按重量份计，包括如下组分：污泥40-80份、杏壳40-80份、椰果壳40-80份、油菜秸秆40-80份、玉米秸秆40-80份、氧化锌10-20份、硅酸镁5-10份、氧化铝5-10份、膨润土10-30份、木炭10-20份、二氧化硅5-10份、硅酸钙3-5份、聚乙烯醇1-3份、氧化钙3-5份、羧甲基纤维素钠乳化剂3-5份。
本发明的有益效果如下：本发明在活性炭吸附剂制备配方中加入杏壳、椰果壳、玉米秸秆、油菜秸秆等天然废弃物质，原料廉价易得，不仅实现了废物利用，废物利用、变废为宝，节约了原材料、保护了环境生态，而且制备的活性炭，比表面积大，具有大量的微孔，吸附容量大，处理程度高，效果稳定，不会产生二次污染。
