Description

一种能净化过滤水的过滤层
技术领域
本发明涉及一种过滤层，尤其是能净化过滤水的过滤层。
背景技术
世界卫生组织(WHO)公布的资料显示，世界上有1/6的人口无法喝到干净的饮用水，致使肠道传染病发病率居高不下、甚至造成传染病暴发、致人死亡，饮水不良引起的疾病种类达到50多种。
我国经济飞速发展的过程同样引发了环境污染、造成水质恶化，严重影响人们的饮水安全。根据我国环境保护部发布的《中国环境状况公报》，我国每年的污水排放量达到600亿吨，占我国可用水资源的6％。2012年，全国地表水国控断面总体为轻度污染。河流的国控断面中，Ⅰ～Ⅲ类、Ⅳ～Ⅴ类和劣Ⅴ类水质断面比例分别为68.9％、20.9％和10.2％；62个国控重点湖泊(水库)中，Ⅰ～Ⅲ类、Ⅳ～Ⅴ类和劣Ⅴ类水质的湖泊(水库)比例分别为61.3％、27.4％和11.3％。对于城市公共供水水质监测，结果显示管网末梢水水质达标率为79.6％，这意味着部分自来水水质也难以保证饮用安全。综合以上数据，为了实现饮水安全，对饮水进行一次或二次净化处理成为人们迫切的希望。
发明内容
本发明要解决的技术问题是提供一种能净化过滤水的过滤层，能提供化学污染物及微生物安全的健康饮用水。
本发明是通过以下技术方案来实现的。
一种能净化过滤水的过滤层，包括按照过滤顺序的至少三层：
树脂过滤层，上述树脂层为多孔状结构过滤层，孔径在0.1-0.3μm；
纳米银过滤层，其中纳米银含量为120-180mg/kg，其粒子大小为2-4nm；
巯基棉层。
目前化学污染物主要为重金属及有机农药、多环芳烃、芳香烃等有机污染物，它们化学性质稳定，难以在较短时间内被分解或降解，而树脂过滤层能有效地吸附这些污染物。
经过树脂过滤层的处理过程，水中残留的有毒有害物质主要是微生物，本级滤芯采用高效杀菌剂——纳米银消除残留在水中的细菌、病毒、霉菌、衣原体等，保证了饮水的微生物安全。
纳米银的杀菌过程中会释放离子态银，利用巯基棉可吸附游离的银离子。
进一步地，上述纳米银过滤层的过滤上游设置有除氯层，上述除氯层内均匀设置有除氯球。
进一步地，上述除氯层与上述树脂过滤层之间设置有活性炭层，上述活性炭层中的活性炭粒径为2-5μm。
进一步地，上述树脂过滤层为XAD大孔树脂。
本发明的有益效果：
除氯层主要起到截留颗粒物，降低原水中游离氯含量、活性炭和大孔树脂的吸附作用消除重金属及有机污染物、纳米银高效快速消毒灭菌作用消除微生物危害、巯基棉吸附游离银离子，最终提供化学污染物及微生物安全的健康饮用水。
具体实施方式
下面根据实施例对本发明作进一步详细说明。
本发明，能净化过滤水的过滤层，设置有五层，包括按照过滤顺序一次为：
除氯层，上述除氯层内均匀设置有除氯球；
活性炭层，上述活性炭层中的活性炭粒径为2-5μm；
树脂过滤层，上述树脂层为多孔状结构过滤层，孔径在0.1-0.3μm；树脂过滤层为XAD大孔树脂；
纳米银过滤层，其中纳米银含量为120-180mg/kg，其粒子大小为2-4nm；
巯基棉层。
目前化学污染物主要为重金属及有机农药、多环芳烃、芳香烃等有机污染物，它们化学性质稳定，难以在较短时间内被分解或降解，而树脂过滤层能有效地吸附这些污染物。
经过树脂过滤层的处理过程，水中残留的有毒有害物质主要是微生物，本级滤芯采用高效杀菌剂——纳米银消除残留在水中的细菌、病毒、霉菌、衣原体等，保证了饮水的微生物安全。
纳米银的杀菌过程中会释放离子态银，利用巯基棉可吸附游离的银离子。
本发明，能净化过滤水的过滤层，除氯层主要起到截留颗粒物，降低原水中游离氯含量、活性炭和大孔树脂的吸附作用消除重金属及有机污染物、纳米银高效快速消毒灭菌作用消除微生物危害、巯基棉吸附游离银离子，最终提供化学污染物及微生物安全的健康饮用水。
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此领域技术的人士能够了解本发明内容并加以实施，并不能以此限制本发明的保护范围。凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围内。
