摘要:
以浦江某城镇污水处理厂二沉池不同径向分布活性污泥为研究对象，分析了污泥的沉降性能和有机质含量，并考察了其对脱氮除磷和SS去除效果的影响。结果表明，沿二沉池径向分布（由内向外）的污泥沉降性逐渐降低，有机质含量逐渐升高，微生物数量先增后减；径向中部活性污泥的脱氮除磷效果更好，SS去除率更高。
Abstract:
The settling performance and organic matter content of different radially distributed activated sludge in the secondary settling tank of a municipal wastewater treatment plant in Pujiang were analyzed, and their effects on nitrogen, phosphorus and SS removal were investigated. Along the radial distribution (from inside to outside) of the secondary settling tank, sludge settleability gradually decreased, organic matter content gradually increased, and the number of microorganisms increased first and then decreased. The activated sludge at the middle of the radial direction had better nitrogen and phosphorus removal performance and higher SS removal efficiency.
