摘   要： 采用造粒、干燥、預熱 、燒結工藝，以油頁巖半焦、粉煤灰、污泥三種固體廢棄物為原料制備污水處理廠用人工陶粒濾料。以鹽酸可溶率、筒壓強度、空隙率和比表面積為陶粒濾料主要性能指標 ，探究陶粒燒制過程中原料配比、燒結溫度及原材料特性等因素對陶粒性能的影響。實驗結果表明： 油頁巖半焦與粉煤灰 的最佳比例為 3 ∶ 5 , 煅燒溫度超過1125 ℃ 時陶粒的比表面積和空隙率有明顯的降低 。隨著陶粒原料中污泥含量的提高，鹽酸可溶率和筒壓強度逐漸降低，而空隙率和比表面積逐漸升高，但仍符合 CJ/T 299- 2008 標準的要求 。油頁巖半焦中殘余的有機組分有利于陶粒制備過程中孔隙的形成。

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
