摘要
氧化塘是一种传统的污水处理设施,它具有投资少、运行管理方便、节省能源、处理效果稳定等优点.缺点是占地大。氧化塘的处理效率取决于两方面:一是生物处理效率;二是水力效率.如何改善氧化塘的水力效率、缩小占地,是具有重要实用价值而研究很不充分的课题.本文系统地综述了国内外氧化塘几何形状对水力特性的影响、氧化塘流型、数学模型研究成果.
The lagoon is a traditional technique of purification of waste water.It is cost effective,easy to manage,to save energy source and stable for puri- fication efficiency.Its shortcoming is to occupy more land. The purification efficiency of a lagoon depends both on biochemistry and on hydraulics.It is a valuable topic not fully studied that how to improve hydraulic efficiency.Studies on the effect of geometry on hydraulic efficie- ncy,flow type and its mathematic modeling in lagoon in China and other countries are synthesized in this Paper.
