Description

一种脱氟饮用水净化剂及其制备方法
技术领域
本发明属于新能源及环保节能技术领域,尤其涉及一种脱氟饮用水净化剂及其制备方法。
背景技术
在我国一些地区,饮用水中氟含量竟高达5.0mg/l以上,远远超出国家饮水标准中所规定的含氟指标。目前,饮用水的除氟方法,国内是以吸附法为主,国外近几年出现了反渗透法。就吸附方法而言,多数都是采用单纯一种吸附剂实现吸附除氟过程的,例如,有的是采用活性氧化铝为吸附剂,有的是采用氯化铝为吸附剂,有的是采用沸石为吸附剂。这些采用单纯一种吸附剂的除氟方法,在其实施的过程中还有不尽人意之处,例如,有的吸附剂吸附能力及吸附容量低,除氟效率差,有的吸附剂价格比较昂贵。
发明内容
鉴于现有技术所存在的问题,本发明的目的在于提供一种能够有效净化饮用水的净化剂。
本发明解决上述技术问题的技术方案如下:一种脱氟饮用水净化剂,包括以下重量份组分:二氧化钛20-40份,5-15份,氧化铁20-50份,丝光沸石10-30份,硅石粉5-7份,沸石粉5-15份,活性碳5-15份,丙烯酰胺为10-30份
在上述技术方案的基础上,本发明还可以做如下改进。
进一步地,所述脱氟饮用水净化剂包括以下重量份组分:20份二氧化钛,20份氧化铁,10份丝光沸石,5份硅石粉,5份沸石粉,5份活性碳,10份丙烯酰胺。
进一步地,所述脱氟饮用水净化剂包括以下重量份组分:40份二氧化钛,50份氧化铁,30份丝光沸石,7份硅石粉,15份沸石粉,15份活性碳,30份丙烯酰胺。
进一步地,所述脱氟饮用水净化剂包括以下重量份组分:30份二氧化钛,30份氧化铁,30份丝光沸石,6份硅石粉,8份沸石粉,10份活性碳20份丙烯酰胺。
进一步地,所述活性炭为椰壳炭或果壳炭。
本发明还提供了一种脱氟饮用水净化剂的制备方法,包括以下步骤:按重量份配比称取以下组分:二氧化钛,,氧化铁,丝光沸石,硅石粉,沸石粉,活性碳,将上述组分在150-200℃下进行干燥处理,粉碎并混合均匀。
具体实施方式
以下对本发明的原理和特征进行描述,所举实例只用于解释本发明,并非用于限定本发明的范围。
本发明提供了一种脱氟饮用水净化剂,包括以下重量份组分:二氧化钛20-40份,5-15份,氧化铁20-50份,丝光沸石10-30份,硅石粉5-7份,沸石粉5-15份,活性碳5-15份,丙烯酰胺为10-30份。
本发明的技术方案通过合理的配比以及各组分的组合具有显著的净化水质的效果、并且制造方便、净化快速;采用本发明的饮用水净化剂,既能有效地从水中除去铬和氟离子,又不会降低水的流速;采用本发明的饮用水净化剂,不仅净化效果可靠、造价低廉、使用方便、环境友好,而且能够有效的增加脱氟脱氟效果,对于含有铬和氟的饮用水有着很好的去除效果。克服了常规净水剂不易混合均匀的缺点,并且使用效果优良,天然无毒,无味,物理化学性质优良,净化后的饮用水不含有对人体有害的铝元素。该饮用水净化剂携带使用方便,可解决因农村供水分散、供水量小而难以净化的问题。该饮用水净化剂使用成本低廉、没有废弃物产生,经过该饮用水净化剂净化后的水可直接达到饮用水的标准,同时,制备该饮用水净化剂的方法简单便捷,易于操作,且本申请提供的饮用水净化剂吸附容量高,除氟效率高,性价比高等优点。
活性炭具有多孔,比表面积大,吸附能力强等优点,不仅可以吸附水中杂质,又可吸附一定量的重金属离子;二者在自然界中储量大,价格低,生产成本低,流程短,操作简便,适合工业化生产。利用本发明净化剂有效地降低了饮用水中铬和酚,可使水源水中Cr(铬)的去除率在78.5%~94.2%、氟的去除率达88.6%~95.3%;再加上其能够补充水源水中的微量元素,使水源水得到了有效地净化、同时大大地提高了饮用水源的质量。
下面通过具体的实施例来进行介绍。
