摘要
针对水处理工艺偏重生物技术、一定程度忽视固液分离技术开发的倾向,分类回顾常见分离技术以强调其地位与作用,着重介绍硅藻土、磁分离及微砂沉淀等三种新型沉淀技术和活性砂过滤、动态膜及滤布滤池等新型过滤技术,总结新型分离技术在污水处理中的研究、应用现状及发展前景,提出新技术在推广中应注意的问题。
Great emphasis has been placed in recent decades on the research of biological technologies in the area of wastewater treatment,while attention has not been paid enough on the role of solid-liquid separation technologies in the process of wastewater treatment. To evaluate importance of the solid-liquid separation technologies in a more comprehensive scale in wastewater treatment processes,several typical novel solid-liquid separation technologies were inclusively reviewed,including three precipitation technologies such as diatomite technology,magnetic separation technology and Actiflo technology,and rapid sand filtration technology,dynamic membrane technology and cloth-media filtration technology. The state of the art and future trend in above separation technologies were also summarized to guide field application.
