摘　　要：纳米二氧化钛(TiO2)光催化技术是一种新型污染治理技术,尤其是在水质净化、污水处理方面得到了广泛的应用。文章以规则的粘土陶粒为载体,高铝酸盐为粘结剂制备出了漂浮型光催化球体材料。在室外太阳光的照射下,球形催化剂材料对污染景观水表现出了很好的COD降解效果,同时实际应用中可以很好的防止水质污染。Nano-titanium dioxide （TiO_2） photocatalysis technology is a new Pollution treatment technology, especially inpurify water quality and sewage treatment, which have been widely used. In this work, we prepared the spherical photocatalytic materials by ceramic clay as carrier, perhafnate as binder. In the outdoor, spherical eatalystmaterial contamination emerged a good COD degradation effect in treating landscape water under sunlight.
