摘　　要：针对海水冲厕工程的实施 ,试验研究了无机盐对活性污泥沉降性的影响。以无盐稳定运行系统作为参照系统 ,分别研究了 2 0g L和 35g L盐度驯化系统内活性污泥絮凝体的形态、污泥沉降特点以及污泥微生物生态。在此基础上探讨了絮凝体的结构。试验结果表明 ,无机盐改变了活性污泥微生物生态 ,改变了絮凝体的结构 ,加强了污泥的沉降性。This study was initiated to explore the effects of inorganic salts on activated sludge in order to carry out the project to use seawater for flushing toilets.With system treating fresh sewage as control system,experiments were conducted to respectively investigate the morphological characteristics of activated sludge floc,activated sludge settleability and microbiological ecology in the 25 g/L salt acclimated and the 35 g/L salt acclimated activated sludge system.The structure of activated sludge floc was further explored.The results indicated that inorganic salts change microbiological ecology and the structure of floc as well as strengthen activated sludge settleability.
