| 摘 要： | 以城市有机生活垃圾为原料,采用三叶回转窑烧制成陶粒,是一种有效的垃圾资源化处置方式。试验研究了以垃圾、黏土和粉煤灰为原料烧制陶粒的最佳原材料配比和最优焙烧条件,结果表明,1)烧制陶粒的最佳原材料配比(干混合比):垃圾15.38%,黏土14.85%,粉煤灰69.77%;2)最优焙烧条件:窑预热温度500℃,烧成温度1190℃,烧成温度保持时间4min。以最优试验方案制得的陶粒堆积密度为605kg/m3,筒压强度为3.0Mpa,吸水率为11.0%,软化系数为0.93,满足GB/T17431.1—1998规定的普通轻集料700级的技术要求;陶粒浸出毒性实验表明浸出液中各项重金属含量均远低于GB/T5085.3—2007规定的浓度限值,具有环境安全性。
