污水的生物处理——生物转盘法

Summarization of Wastewater Biological Treatment: RBC

从生物转盘的处理原理及基本特性出发 ,综述了该技术在生活污水、脱氮除磷、含酚废水和其他工业废水处理领域中的应用情况 ,分析了生物转盘废水处理过程中的几个重要因素 ,如盘片材料、转盘转数、浸没百分比、水力停留时间等对处理效果及投资与维护的影响 ,最后提出转盘材料的研发及系统长期稳定运行条件的研究等问题是生物转盘今后在水处理中的主要发展方向。

This text began from the reaction mechanism and characteristics of Rotating Biological Contactor (RBC), and summarized in detail the up-to-date applications in wastewater treatment, such as the treatment of domestic sewage, ammonia wastewater, phenol wastewater and other industrial wastewater. The factors including material, rotational speed, submergence of the disc and HRT in the treatment of RBC were analyzed to get to an optimal condition. Several dynamic and hydraulic models were put out. In the last the prospect of RBC in wastewater treatment were put forward, that is, the development of disc material and the long-term stable run of RBC and so on.
