Description
技术领域
本发明属于废水处理技术领域，涉及一种含有沸石粉的废水过滤材料的制备方法。
背景技术
工业废水包括生产废水、生产污水及冷却水，是指工业生产过程中产生的废水和废液，其中含有随水流失的工业生产用料、中间产物、副产品以及生产过程中产生的污染物，工业废水种类繁多，成分复杂，例如电解盐工业废水中含有汞，重金属冶炼工业废水含铅、镉等各种金属，电镀工业废水中含氰化物和铬等各种重金属，石油炼制工业废水中含酚，农药制造工业废水中含各种农药等，由于工业废水中常含有多种有毒物质，污染环境对人类健康有很大危害，因此要开发综合利用，化害为利，并根据废水中污染物成分和浓度，采取相应的净化措施进行处置后，才可排放；目前，在对工业废水进行化学处理之前，均需要先对其进行过滤处理，现有过滤处理过程中所用的过滤材料只能简单的过滤掉工业废水中的杂质，过滤效果不好，过滤效率差。
发明内容
本发明的目的是提供一种含有沸石粉的废水过滤材料的制备方法，解决了现有技术中存在的过滤材料过滤效果不好，过滤效率差问题。
本发明所采用的技术方案是，一种含有沸石粉的废水过滤材料的制备方法，具体按照以下步骤实施：
步骤1、按重量份配比的称取以下成分：沸石粉40-70份、石英砂35-45份、麦饭石4-9份、硅藻土10-20分、膨润土14-27分、碳酸钙30-45份、改性凹凸棒土10-20份、石墨烯3-7份，棉麻纤维织物20-32份、多孔陶瓷基体10-15份、纳米改性活性炭6-11份；、烯丙基磺酸钠1-3份、双硬脂酰基二乙烯三胺5-9份、氧化钛4-11份；
步骤2、将石墨烯、石英砂、麦饭石、硅藻土、膨润土、碳酸钙、改性凹凸棒土、混合后加入粉碎机中粉碎，之后过100目筛，得到混合物A；
步骤3、将烯丙基磺酸钠、双硬脂酰基二乙烯三胺、氧化钛混合后加入搅拌罐中低速搅拌，之后静置，得到混合物B；
步骤4、在混合物A中加入混合物B，充分混合后进行超声振荡处理，之后进行烘干并造粒；
步骤5、棉麻纤维织物位于最底层，所得的颗粒位于中间层，多孔陶瓷基体和纳米改性活性炭混合后位于最顶层，得到有沸石粉的废水过滤材料。
本发明的特点还在于：
步骤2中粉碎速率为300-500转/分，时间为10min-15min。
步骤3中搅拌速率为50-80转/分，时间为10min-25min，静置时间为20min。
步骤4中超声功率为1000～1200W，时间为20～30min。
步骤1中纳米改性活性炭是体积为0.25～0.4cm3的颗粒。
步骤1中多孔陶瓷基体是体积为0.3～0.5cm3的颗粒。
本发明的有益效果是：发明制备工艺简单，制得的过滤材料性能稳定，能够在较长时间里有效清除污水中的氮、磷、大肠杆菌等有害物质，环保性能好，能够提高排放水的水质；其中，本发明中添加的多孔陶瓷基体能够在吸水后能够形成吸附膜，能够提高了吸附效果；本发明中添加的石墨烯对有机物有较强的吸附能力，包括微生物难以降解的有机物。污水经石墨烯处理后，BOD可降低99％，TOC可降低1-2mg/L，同时还具有脱色除臭，吸附除浊之功能；此外，本发明采用的制备工艺操作简单，成本低，能够提高过滤材料的活性。
