Description

一种陶瓷过滤膜
技术领域
本发明涉及污水净化领域，具体公开了一种陶瓷过滤膜。
背景技术
近年来，国家环保政策对工业废水治理提出了越来越严格的要求和限制，废水处理及高效回收利用受到广泛重视。为了提高废水的重复利用率，过滤膜技术成为废水回用的重要手段，将工业生产和居民生活中的污水处理后循环利用。
目前，最常见的过滤膜为聚合物过滤膜，然而其稳定性不高，寿命短，经常性的更换增加了使用成本。
发明内容
为了克服现有技术中存在的缺点和不足，本发明的目的在于提供一种陶瓷过滤膜。
为实现上述目的，本发明采用如下方案。
一种陶瓷过滤膜，其特征在于：包括多孔陶瓷基体和基体表面的等离子喷涂金属铂，其中基体由白土、沸石粉、石墨烯、云母粉、玉米粉、叶绿泥石、活性炭纤维组成。
上述配比的陶瓷过滤膜可以对水中的重金属离子和细菌进行有效的过滤。陶瓷基体表面的金属铂等离子涂层具有较强的亲水能力，可以提高过滤膜的水通量。
进一步的，多孔陶瓷基材由白土35-67份、沸石粉12-23份、石墨烯6-8份、云母粉11-13份、玉米粉2-4份、叶绿泥石7-9份、活性炭纤维20-34份组成。
进一步的，所述多孔陶瓷基体的孔隙率为65-78%。
进一步的，所述多孔陶瓷基体的孔径为5-8微米。
陶瓷过滤膜的制备方法为：将多孔陶瓷基材的原料白土、沸石粉、石墨烯、云母粉、玉米粉、叶绿泥石混合后，加入到丙酮溶液中，在高能球磨机中球磨10小时，干燥后研磨，过筛，然后将过筛物压成片状，第一次烧结，得到多孔陶瓷基材；通过等离子体发射器在多孔陶瓷基材表面形成铂涂层，第二次烧结，冷却后形成陶瓷过滤膜。
进一步的，第一次烧结在空气气氛中进行，升温速率4℃/s，升温至350℃保温2小时，然后升温到650℃保温10小时；第二次烧结在氩气气氛下进行，升温速率3℃/s，升温至1050℃保温12小时。
本发明的有益效果：本发明的陶瓷过滤膜与现有技术相比强度高，不易受污染，稳定性好，可以长期使用，降低了污水处理成本。
具体实施方式
为了便于本领域技术人员的理解，下面结合实施例对本发明作进一步的说明，实施方式提及的内容并非对本发明的限定。
