摘　　要：利用制革污泥与普通粘土在1120～1190℃温度下混合烧结制备新型陶粒。试验烧制了6种不同配比的陶粒试样,对其松散容重、1h吸水率、颗粒容重、抗压强度及铬溶出量进行了测定并加以对比分析。根据测试结果探究利用制革污泥与黏土掺合烧制陶粒的方法。如此不但可以固定污泥中的铬等重金属,杀灭大量病原菌,而且可使污泥变废为宝,为制革污泥的治理提供新的思路与途径。Novel ceramisite was produced by sintering mixes of dried tannery sludge and ordinary clay between 1 120℃ and 1 190℃. Six ceramic samples with different ratios of clay/sludge were produced. The loose bulk density, 1 h water absorption, particle density, compressive strength and leaching of chromium were determined and compared with. According to the test re sults, we explore the method of sintering ceramisite by tannery sludge and clay. Not only the chrome can been fixed, the bacteria killed, but the sludge can be reuse. It provides a new idea and approach for the treatment of the tannery sludge.
