摘要：

为了探索污泥烧制陶粒的新方法,在系统分析污泥理化性质的基础上,研究污泥陶粒的制备工艺及性能.结合污泥低温干化的技术特点,建立污泥干化与陶粒烧制一体化的工艺流程.研究结果表明,污泥的Al2O3和Na2O+K2O质量分数在可用于烧制陶粒的化学组成范围内,SiO2的质量分数接近于48%的下限值,具备烧制污泥陶粒的基本条件；污泥陶粒的抗压强度随着表观密度的增加而增大,烧制温度对污泥陶粒的抗压强度和表观密度产生明显影响,在1 075 ℃时烧制的污泥陶粒具有最大的抗压强度（71.7 MPa）和表观密度（2.45 g/cm3）,污泥陶粒的吸水率随烧制温度的增加而减小.
Abstract:

The characteristics of sludge haydite and sintering technology were analyzed based on systematic analysis on the physicochemical properties of sludge in order to provide a new way to sinter haydite by sewage sludge. A sintering technology integrated with sludge drying was established combined with the characteristics of sludge drying at lowtemperature. Results showed that the mass fraction of Al2O3 and Na2O+K2O in sludge was suitable to sinter haydite, and the mass fraction of SiO2 was near to 48% which is the lower limit of sintering haydite, therefore the sludge met the basic conditions to sinter haydite. The compressive strength of haydite increased with the increase of apparent density. Sintering temperature had great impact on the compressive strength and apparent density of haydite. Sintered haydite had maximum compressive strength (71.7 MPa) and apparent density （2.45 g/cm3）at 1 075 ℃. The water absorbing capacity of haydite decreased with the increase of sintering temperature.
