- Title:
- Research and Application Progress of High-performance Sedimentation Tank in Domestic Sewage Advanced Treatment
- 摘要:
- 以污泥回流为特点的非介质强化高效沉淀池在市政污水深度处理领域已得到了广泛的推广与应用，通过对相关研究报告的跟踪和整理，概述了我国污泥回流高效沉淀池在市政污水深度处理中的应用研究趋势，介绍了斜管区表面负荷、混合区停留时间、絮凝区停留时间等设计参数，以及进出水水质、药剂类型、药剂投加量、污泥回流比等运行参数的应用研究现状，并总结了现阶段研究的不足及发展方向。
- Abstract:
- High-performance sedimentation tank with sludge recycling has been widely used in the advanced treatment of domestic sewage. The research and application progress of the high-performance sedimentation tank were reviewed by tracking and sorting out relevant research. Process and design parameters including surface load of inclined-tube zone, residence time of coagulation mixing zone and flocculation zone, influent and effluent quality, chemicals type and dosage, sludge return ratio, etc., were introduced. Existing problems and development prospects of current research were also expounded.
