Plate-shaped ceramsite prepared from dewatered sludge as well as preparation method and application of plate-shaped ceramsite
The invention relates to a method for preparing plate-shaped ceramsite from dewatered sludge and application, and belongs to the field of sewage treatment technologies and building materials. The preparation method comprises the following steps: 1) drying loess solid and sludge solid according to a mass ratio of 8:5 to 2:5, and taking the loess solid and the sludge solid; 2) manually manufacturinga ceramsite plate; 3) roasting the ceramsite plate at high temperature; and 4) coating the cooled ceramsite plate with a blended glaze for secondary firing. When the plate-shaped ceramsite prepared from the dewatered sludge is used for treating phosphorus-containing wastewater, the optimal ceramsite adding amount is 20g/L, the optimal hydraulic retention time is 7d, and the removal rate of phosphorus in the wastewater reaches 90% under the optimal condition. Resource utilization of the sludge is achieved, energy conservation and environmental protection are achieved, and the plate-shaped ceramsite has wider market and more outstanding performance.
本发明涉及一种用脱水污泥制备板型陶粒的方法及应用，属于污水处理技术及建筑材料领域。制备方法包括如下步骤：1)将黄土固体和污泥固体烘干，按质量比，8:5～2:5，取黄土固体和污泥固体；2)手工制作陶粒板；3)将陶粒板高温焙烧；4)冷却后的陶粒板涂上调配好的釉料进行二次烧制。用脱水污泥制备的板型陶粒在处理含磷废水时，最佳陶粒投加量为20g/L，最佳水力停留时间是7d，在最佳条件下，污水中磷的去除率达到90％。实现了污泥的资源化利用，节能环保，更具有广泛的市场及更突出的性能。
