摘　　要：以城市污泥为原料,配以玻璃粉为辅料制备轻质陶粒,研究了原料配比和焙烧温度对陶粒性能的影响。结果表明按污泥75%、玻璃粉25%,600℃预热30 min、1100℃焙烧并保温10 min,可以制备出符合国家标准GB/T17431-2010的600级轻质陶粒。微观结构分析表明,烧胀陶粒表面呈现高度釉化,内部断面则呈现封闭孔隙结构。The light weight ceramsite was produced by using sewage sludge with the glass powder.Sintering parameters and mix proportion have significant impact on the performance of ceramsite. The results show that according to the ratio of sewage sludge 75% and glass powder 25%,ceramsite was prepared by preheated 30 min at 600 ℃ and calcined 10 min at 1100 ℃. It can meet the 600 grade of state standard GB / T17431-2010. Through the analysis of microstructure,it showed that the ceramsite have a succession glaze layer in surface and closed pore structure in inside.
