Description

一种利用废弃暖贴制备复合蛭石矿物质滤料
技术领域
本发明专利涉及一种利用废弃暖贴制备复合蛭石矿物质滤料。
背景技术
滤料可作为工业废水高负荷生物滤料池的生物挂膜载体,自来水的微污染水源,预处理的生物滤池.含油废水的粗粒化材料,离子交换树脂垫层,微生物干燥贮存;适用于饮用水的深度处理,它具有吸附水体中的有害元素,细菌,矿化水质,是活性生物降解有害物质效果最好的滤料,和生物滤池中最好的生物膜载体。
暖贴是现在冬季的热销品,它的原料层是由铁粉、蛭石、活性炭、无机盐、水等合成的聚合物,可在空气中氧气的作用下发生放热反应。暖贴是利用铁氧化反应放热来发热。实际上也就是根据铁在潮湿空气中发生吸氧腐蚀的原理。同时利用活性炭的强吸附剂,在活性炭的疏松结构中储有水蒸气,水蒸气液化成水滴,流出与空气和铁粉接触,在氯化钠的催化作用下较为迅速的发生反应生成氢氧化铁,放出热量。使用后为黑褐色固体,其中含碳粉、氯化钠固体、三氧化二铁固体以及含镁铝的盐类。
蛭石是粘土矿物,它的常见化学成分为Mg,Ca,Mg,Fe,Al,Si。一般为褐黄暗绿色,有油一样的光泽,加热后变成灰色。蛭石可用作建筑材料、吸附剂、防火绝缘材料、机械润滑剂、土壤改良剂等等,用途广泛。
发明内容
本发明涉及一种废水滤料,具体目的在于利用废弃暖贴制备复合蛭石矿物质滤料。
为了实现上述目的,本发明采用的技术方案如下:
一种利用废弃暖贴制备复合蛭石矿物质滤料,其特征在于:所述滤料由下列物质组成:氯化钠,活性炭,三氧化二铁,蛭石。
所诉的一种利用废弃暖贴制备复合蛭石矿物质滤料的制备方法包括以下步骤:
粉磨过程:首先将废弃物放置100℃下烘干,利用球磨机将废弃暖贴颗粒磨成粉末,粉末的细度在200目。制粒过程:将废弃暖贴跟普通硅酸盐水泥按质量比4:1混合均匀,制得料粉备用。采用手动成球方式,布水,成球,制得球型滤料半成品,在不同直径模具中筛选球形颗粒,将成型的滤料颗粒于自然状态下风干。养护过程:采用恒温养护箱对滤料半成品进行养护,养护箱湿度保持99%,温度为20℃,养护3到7天,即可成型。经养护过的半成品滤料放入水中浸泡并多次洗涤,其目的为将滤料中的成孔剂成分氯化钠溶于水而形成多孔结构。然后将滤料置于105℃烘干,即可得到成品复合蛭石矿物质滤料。
