CN102826829A 一种用于处理环己酮废水的陶粒及其制备方法与应用 无效 - 驳回

一种用于处理环己酮废水的陶粒及其制备方法与应用
摘要：
本发明涉及一种用于处理环己酮废水的陶粒，包括阴极陶粒和阳极陶粒，所述阴极陶粒包括如下原料：粘土、干化污泥和粘结剂；所述阴极陶粒的堆积密度为850~900kg/m3，颗粒密度1200~1300kg/m3，吸水率为12-13wt%；所述阳极陶粒包括如下原料：粘土、铁屑和粘结剂；所述阳极陶粒的堆积密度为910-950kg/m3，颗粒密度为1400~1500kg/m3，吸水率为14-15wt%。本发明所述的陶粒颗粒密度较小，有效防止填料板结，大大提高了对反应器反冲洗的效率。本发明采用废铁屑和污泥为原料烧制陶粒，既节约了黏土，又实现了固废的资源化利用。
摘要（英）：

The invention relates to ceramsites for treating cyclohexanone waste water and its preparation method and use. The ceramsites comprises cathode ceramsites and anode ceramsites. The cathode ceramsites comprise clay, dried sludge and a binder and have bulk density of 850 to 900kg/m<3>, grain density of 1200 to 1300kg/m<3> and water absorption of 12 to 13wt%. The anode ceramsites comprise clay, iron filings and a binder and have bulk density of 910 to 950kg/m<3>, grain density of 1400 to 1500kg/m<3> and water absorption of 14 to 15wt%. The ceramsites have low grain density, can effectively prevent filler hardening and can greatly improve reactor backwashing efficiency. The preparation method utilizes waste iron filings and sludge as materials for preparation of the ceramsites, saves clay and realizes solid waste resource utilization.
