Description
技术领域
本发明涉及用于净化受到磷、氨、亚硝酸、和硝酸等污染的水的净化材料，及其制造方法。本发明的净化材料特别适合用于净化用于养殖鱼类和饲养观赏鱼的饲养水。鱼类的饲养水包括江河水、海水、以及湖泊和沼泽水。
背景技术
由于鱼类的饲养水受到鱼类排泄物和饲料残渣的污染，通常在使饲养水循环的同时，用过滤器或其中过滤器与例如活性炭等吸附剂组合的净化材料来除去饲养水中的污染物。
然而，由于常规吸附剂不能完全去除磷、氨、亚硝酸、和硝酸等，因此蓝绿藻的产生(blooms)等不可避免。因此需要定期清洁饲养槽的壁表面。
在水中添加非常少量的杀菌剂是防止例如蓝绿藻等藻类产生的有效手段，但是不适合于食用鱼的养殖用饲养水。
提出的吸附和除去水中的磷组分的净化剂的实例包括通过中和羟基氧化铁(ironoxyhydroxide)而获得的比表面积大的材料(专利文献1)，通过中和硫酸亚铁和硫酸铁的混合液使得材料组成为Fe(OH)m(SO4)n·1H2O(其中2≤m<3，0<n≤0.5，和0≤1<0.5)而获得的材料(专利文献2)，通过用微生物浸渍通过将氧化钛、氧化锆、沸石、氧化铁、和氧化锰混合和烧结而获得的多孔陶瓷颗粒而获得的材料(专利文献3)，通过向亚铁的水溶液中添加小于亚铁当量的量的氧化材料并且然后添加碱使得将pH调节至1.5-5.5而获得的包含氢氧化铁的非晶质阴离子吸附剂(专利文献4)，和通过在选自活性炭、沸石、硅胶、珠光体、和多孔玻璃等的至少一种多孔载体的表面上通过蒸发或真空沉积而形成光催化剂膜并且能够支承光催化剂膜或者通过用作为光催化剂的有机金属化合物的溶液或分散液浸渍多孔载体并且通过加热进行分解而获得的材料(专利文献5)。
与常规吸附剂相比，这些净化剂示出改善的磷除去率，但是在非常少量营养的情况下，例如蓝绿藻等藻类生长，因此，不能完全防止藻类的产生。
如上所述，期望开发对于饲养鱼是安全的并且可以长期防止藻类的产生的净化剂。

发明内容
发明要解决的问题
本发明的一个目的是提供一种净化剂，其可以同时除去污染水中的磷、氨、亚硝酸、和硝酸等，其当应用于鱼类的饲养水的净化时对于饲养鱼是安全的，并且可以完全或长时间防止饲养水中藻类的产生。
用于解决问题的方案
由于开发了具有聚合硫酸铁(polyferric sulfate)作为主组分的水处理用絮凝剂，因此本发明人研究了氢氧化铁在制造和使用时显示的形状(例如α、β、γ、和无定形)和对有害物质的除去性能，并且进行各种检查，发现通过将通过在特定条件下用苛性钠中和以特定配方包含二价铁离子、硫酸根、氯离子、钛离子、镁离子、和二氧化硅(硅离子)的溶液而获得的中和产物过滤和干燥而获得的材料作为水处理材料示出高性能。由此完成本发明。
本发明人对如上所述聚合硫酸铁的制造进行各种检查，还发现通过将聚合硫酸铁的制造中产生的废液与从钢铁工业相关的酸洗过程中排出的废液混合并且调节混合物来满足含铁溶液的以上条件。使用这些废液作为原材料可以降低本发明的净化剂的制造成本，从而降低在聚合硫酸铁的制造过程和钢铁工业相关的酸洗过程中排出的废液的处理成本。
进行本发明的方式如下。
[1]一种水净化材料，其具有以重量比计为30至40％的总铁、1至5％的钛、0.1至1％的镁、和0.1至0.8％的二氧化硅(硅)的组成。
[2]一种水净化材料的制造方法，其包括在30℃至50℃和pH为6.8至7.2的条件下将苛性钠添加至包含200至100mg/L的二价铁、20至100mg/L的钛离子、5至50mg/L的镁、和3至30mg/L的二氧化硅的溶液中，以进行中和和反应；在100℃以下将获得的固形物分离和回收；并且将回收的固形物干燥。
[3]根据[2]的水净化材料的制造方法，其中溶液通过将从聚合硫酸铁的制造过程排出的废液和从与钢铁工业相关的酸洗过程排出的废液组合来制备。
[4]根据[2]或[3]的水净化材料的制造方法，其中溶液中的铁包括硫酸铁(Fe+2)或硫酸铁(Fe+2)和硫酸亚铁(Fe+3)的混合物。
本发明的净化材料的组分的配方比例基于各元素以重量比计来表示。例如，30％的总铁通过用样品中包含的铁的分析(重量)值除以样品的总重量，即，Fe的重量/总重量×100来计算。
进一步详细描述本发明。在中和时将pH调节为6.8至7.2，因为在该范围内，产物包含最大含量的无定形产物，并且示出最好的吸附性能。pH为7.2以上，倾向于形成磁铁矿的晶体，并且pH为9以上，产物大部分变成磁铁矿。pH为6.8以下，二价铁的一部分溶解为离子，以降低形成的沉淀物的量，并且Fe+2残留在溶液中。
将中和时的温度设定为30℃以上，因为在30℃以下反应性差，导致通过Fe、Mg、Si、和Ti的反应，锐钛矿型TiO4，Fe、Mg、和Si的化合物，以及Fe的无定形氢氧化物的生成不良，并且因为需要加热以达到50℃以上，这需要高成本并且是不实用的。通过如上所述将中和时的温度设定为30至50℃，可以以低成本制造净化剂。
在本发明的净化剂中所包含的除了铁以外的金属组分当中，钛和镁包含在来自聚合硫酸铁的制造过程的废液中，并且二氧化硅包含在来自过滤过程和酸洗过程的废液中。在这些组分当中，钛用作光催化剂，但是钛含量为5％以上对磷(P)的吸附具有副作用，这是不优选的。当含量为1％以下时，不能充分发挥足作为光催化剂的功能。
如果本发明的净化剂的组成比例极大地偏离上述范围，则污染物组分的吸附能力降低。原因尚不清楚，但认为是例如类似于铝酸镁和沸石等的化合物等Fe、Mg、和Si化合物，更具体地，例如在沸石的通式Mn+x/nAlxSiyO2x+2yx-·zH2O中Mg和Fe3+分别用M和Al取代的类似于沸石的化合物，如果存在Al则包含Al和Fe3+的沸石型化合物，MgO·SiO2·nH2O，和Mg3SiO4O10(OH)2等未充分结晶的化合物的生成，并且推测以优异的吸附能力而高效地除去废水中的污染物组分。
在本发明中，苛性钠的量足以使得全部溶解的金属化合物不溶化，并且可以将苛性钠添加至溶液中，使得pH落入6.8至7.2的范围内，同时观察固形物的析出状态。苛性钠的添加优选通过与pH计连接来控制。
可以将已知的方式用于添加，只要可以以少量将苛性钠的水溶液添加并且混合至溶液中即可。例如，可以使用设置有搅拌装置的反应容器。
从溶液中分离中和反应后生成的固形物的方法可以为任意种类，只要不涉及加热即可，并且实例包括用于加压过滤的压滤机和用于离心分离的污泥处理中使用的离心分离机。
回收的固形物的干燥方式可以为任意种类，只要该方法不涉及加热至100℃以上即可，并且实例包括日光干燥、自然干燥、和利用废热的减压干燥机。如果将固形物加热至100℃以上，则固形物的物理性质变化，并且吸附性能受损。
发明的效果
用本发明的净化剂，与常规制品相比，可以更有效地除去水中所包含的非常少量的磷、氨、亚硝酸、和硝酸等，并且特别地，如果应用于鱼类饲养水，则可以高效地除去水中的磷组分，使得可以长期防止蓝绿藻的善生和蓝绿藻对玻璃表面的附着。
此外，使用在聚合硫酸铁的制造过程中排出的废液和在与钢铁工业相关的酸洗过程中排出的废液作为原材料降低了制造成本和废液的处理成本。
