摘   要： 采用造粒、干燥、预热 、烧结工艺，以油页岩半焦、粉煤灰、污泥三种固体废弃物为原料制备污水处理厂用人工陶粒滤料。以盐酸可溶率、筒压强度、空隙率和比表面积为陶粒滤料主要性能指标 ，探究陶粒烧制过程中原料配比、烧结温度及原材料特性等因素对陶粒性能的影响。实验结果表明： 油页岩半焦与粉煤灰 的最佳比例为 3 ∶ 5 , 煅烧温度超过1125 ℃ 时陶粒的比表面积和空隙率有明显的降低 。随着陶粒原料中污泥含量的提高，盐酸可溶率和筒压强度逐渐降低，而空隙率和比表面积逐渐升高，但仍符合 CJ/T 299- 2008 标准的要求 。油页岩半焦中残余的有机组分有利于陶粒制备过程中孔隙的形成。

Abstract: Using granulation, drying, preheating, and sintering processes, three solid wastes of oil shale semi-coke, fly ash, and sludge are used as raw materials to prepare artificial ceramsite filter materials for sewage treatment plants. Taking hydrochloric acid solubility, cylinder compressive strength, porosity and specific surface area as the main performance indicators of ceramsite filter materials, the influence of factors such as the ratio of raw materials, sintering temperature and raw material characteristics on the performance of ceramsite is explored. The experimental results show that the best ratio of oil shale semi-coke to fly ash is 3:5, and the specific surface area and porosity of ceramsite are significantly reduced when the calcination temperature exceeds 1125℃. With the increase in the proportion of sludge in the ceramsite raw materials, the hydrochloric acid soluble rate and the cylinder pressure strength gradually decrease, while the porosity and specific surface area gradually increase, but they still fulfill the requirements of the CJ/T 299-2008 standard. The residual organic components in oil shale semi-coke are beneficial to the formation of pores during the preparation of ceramsite.
Keywords: sludge; oil shale semi-coke; fly ash; artificial ceramsite filter material
