Description

一种水处理陶粒的制备方法
技术领域
本发明涉及水处理材料领域，尤其是涉及一种水处理陶粒的制备方法。
背景技术
近年来我国工业废水、生活污水排放总量呈逐年增加趋势，而污水处理率并没有得到显著的提高，导致饮用水源污染严重。
陶粒作为一种新型填料，其作用在于陶粒上具有很大的开孔率和发达的孔隙，比表面积大，在水处理工艺中，陶粒可以凭借其丰富的孔隙对水中的污染物进行有效吸附，达到净化水质的目的。
电气石是电气石族矿物的总称，电气石颗粒受热后，两端带正负不同的静电，以致吸引灰尘等细小物体，由于这种矿物所具有的热电性而称其为电气石。电气石化学成分复杂，是以含硼为特征的铝、钠、铁、镁、锂的环状结构的硅酸盐矿物。具有显著的热电性，压电性，透明的晶体纵向切面有偏光和多色性等特点。
电气石能与带电粒子发生反应，吸附空气中的粉尘，处理工厂废气，净化水质，处理污水，能中和水中的酸碱。研究表明，电气石对污水中重金属的吸附主要有表面配位吸附，离子交换吸附和物理吸附等，电气石作为环境矿物净化材料，吸附容量大，处理效果好，而且不易产生二次污染，显示了其在污水处理中良好的应用前景。

(2)在上述混合均匀的物料中喷入雾状的水，使混合物中水的质量百分含量为20-30％，然后将所得到的均化的混合物料经压机压制成生料球，筛选出粒径为10-20mm的生料球进行圆化处理；
(3)将圆化处理后的生料球进行烧制，先将温度以恒定速率8℃/min升温至450-460℃，在该温度下保温60min，然后以12℃/min的速率将温度升至1100-1150℃，在该温度范围内保温120min，最后自然冷却至室温，即完成用于水处理的陶粒的制备。
