Description

一种铝铁复合微球制备方法及吸附沉降剂制备方法和应用
技术领域
本发明涉及水处理技术领域，尤其涉及一种铝铁复合微球制备方法及一种吸附沉降剂制备方法和应用。
背景技术
伴随着工业生产的发展以及人们生活水平的提高，工业污水量以及城市生活污水量正以惊人的速度猛增，这些污水或已经或正在污染着人类赖以生存的江、河及湖泊，已构成威协人类生存环境的原因之一。
现代的废水处理方法主要分为物理处理法，物理处理法通过物理作用分离、回收废水中呈悬浮状态的污染物(包括油膜和油珠)的废水处理法，但其处理能力是极其有限的，难以满足及时处理工业及生活污水的实际要求。
发明内容
基于背景技术存在的技术问题，本发明提出了一种铝铁复合微球制备方法及吸附沉降剂制备方法和应用，所得吸附沉降剂具有较大的电极性和丰富的空隙结构，可有效吸附水体中污染物，吸附性能极强，而且重复利用率好，同时成本低廉，经济效益可观。
本发明提出的一种铝铁复合微球制备方法，包括如下步骤：将氢氧化铝、四氧化三铁、腐殖酸混合，研磨，加入聚乙烯醇、乙醇溶液搅拌，喷雾干燥得到铝铁复合微球。
优选地，研磨时间为15-35min，研磨压力为0.12-0.5Mpa。
优选地，加入聚乙烯醇、乙醇溶液搅拌5-12min，搅拌温度为165-180℃。
优选地，喷雾干燥温度为210-225℃。
优选地，氢氧化铝、四氧化三铁、腐殖酸、聚乙烯醇、乙醇溶液的重量比为32-40：2-10：1-4：1-2：60-100，乙醇溶液浓度为20-40wt％。
本发明将氢氧化铝、四氧化三铁、腐殖酸复配研磨，腐殖酸分子结构中的羧基以及酚羟基存在可离解的氢离子，并含有多种极性功能基，一方面与四氧化三铁中的铁离子有很好的络合能力，磁性吸附能力强，且与生物碱具有极好的亲水和氢键作用，另一方面与氢氧化铝的结合强度高，进一步配合聚乙烯醇反应形成氢氧化铝胶状物，经过喷雾干燥后，吸附强度高。
本发明提出的一种吸附沉降剂制备方法，包括如下步骤：
S1、将麦饭石粉、亚麻纤维、尿素、氢氧化钠搅拌，调节体系呈中性，过滤，用水洗涤，干燥，粉碎，浸入二氧化硅悬浮液中搅拌，喷雾干燥得到预制料；
S2、将聚环氧乙烷、高铁酸钠、蒙脱土、煅烧高岭土、果壳碳、预制料、上述所得铝铁复合微球混合均匀，加入活性硅土、海藻酸钠搅拌均匀，干燥得到吸附沉降剂。
优选地，S1中，麦饭石粉、亚麻纤维、尿素、氢氧化钠的重量比为4-12：10-18：1-4：2-4。
优选地，S1中，将麦饭石粉、亚麻纤维、尿素、氢氧化钠搅拌20-40min，搅拌温度为72-80℃，采用浓度0.9-1.4mol/L硫酸溶液调节体系呈中性，过滤，用水洗涤，干燥，粉碎，浸入浓度为0.5-0.9wt％的二氧化硅悬浮液中搅拌1-3h，搅拌温度为90-98℃，喷雾干燥得到预制料。
优选地，S2中，聚环氧乙烷、高铁酸钠、蒙脱土、煅烧高岭土、果壳碳、预制料、上述所得铝铁复合微球、活性硅土、海藻酸钠的重量比为12-25：10-20：2-9：2-6：1-5：4-14：10-18：1-4：2-6。
本发明提出的上述吸附沉降剂制备方法制得的吸附沉降剂作为污水处理剂的应用。
本发明采用麦饭石粉、亚麻纤维经过氢氧化钠碱化后，与尿素的结合程度高，与二氧化硅配合，可有效吸附水体中污染物，再配合铝铁复合微球作用，吸附性能极强，对于大部分有机分子和无机重金属具有很好的吸附与包裹作用，而且重复利用率好，进一步配合聚环氧乙烷、高铁酸钠作用，水分不容易从中通过，而且具有较大的电极性和丰富的空隙结构，针对含重金属的废水吸附效果好，同时成本低廉，经济效益可观。
本发明所得吸附沉降剂可以明显降低水体中的总磷，水体的总磷含量由处理前的8.66mg/L降低至0.28mg/L，去除率达96.8％；对水体中的总氮也有一定的去除效果，水体中的总氮由处理前的33.7mg/L降低至20.6mg/L，去除率为38.9％，而且处理后水体的透明度显著增加，处理前池塘水体的透明度几乎为0，处理后水体的透明度超过了1.0m。
