石灰干化是一种实现污水处理厂产生的污水污泥减容的有效技术。它具有成本效益高、实际操作可行、干度分数高且稳定性好等优点。然而，环境工程面临的重大挑战是解决石灰干化污泥（LDS）的出路问题。由于LDS中的钙是生产水泥的一种潜在原料，本研究对LDS处置与水泥窑结合的可行性以及对水泥烧结的影响进行了研究。结果表明添加LDS（
Lime drying is an effective technique to achieve the volume reduction of sewage sludge produced by wastewater treatment plants. It holds the advantages featuring most cost-effective, practical operation with high dryness fraction and good stability. However, the great challenge facing environmental engineering is to solve the outlet for lime-dried sludge (LDS). Since calcium in LDS is a potential raw material for producing cement, the feasibility of combining LDS disposal with cement kiln and the influence on sintering of cement were investigated in this work. The results indicated that adding LDS (
