| 摘 要： | 在温度35℃、pH=10条件下,对比研究了14 d内剩余污泥在KOH、NaOH、Ca(OH)2和Na2CO3这4种碱性条件下的水解产酸性能、脱水性能、氨氮和正磷酸释放情况以及污泥减量情况.结果表明:剩余污泥在4种碱性条件下表现出不同的水解产酸能力、脱水性能、以及污泥减量情况.污泥水解能力排序为Na2CO3＞NaOH≈KOH＞Ca(OH)2；产酸能力排序为NaOH＞KOH≈Na2CO3＞Ca(OH)2；脱水性能排序为Ca(OH)2＞Na2CO3＞NaOH≈KOH,氨氮和正磷酸盐释放量排序均为为Na2CO3＞ NaOH≈KOH＞Ca(OH)2.剩余污泥在Na2CO3条件下挥发性悬浮固体(VSS)去除率最高；但在NaOH条件下总悬浮固体(TSS)去除率最高.
