摘要
阐述了腐殖土活性污泥工艺的基本原理,从微生物菌群结构、除污效能、控制恶臭气体及改善污泥沉降和脱水性能等方面介绍了该工艺的特性,同时说明了该技术的典型工艺流程及设计参数。实践表明,腐殖土活性污泥工艺可强化对氮、磷的去除,使污泥脱水性能大大改善,实现污水处理流程的无臭化。
The basic principle of humus soil activated sludge process was discussed. The characteristics of the process were presented in the respects of microbial community structure, pollutants removal efficiency, deodorization effect and improvement of sludge settling and dewaterability. The typical process flow and design parameters were demonstrated. The practice shows that the humus soil activated sludge process can enhance nitrogen and phosphorus removal, improve greatly the sludge dewaterability and realize the odorless in wastewater treatment process.
