【摘要】 重力分离是最为常用的油水分离技术,但国内外沿用的传统设计方法只能计算极限粒径,无法计算分离后排放水的含油量,本文提出了一种新的设计方法．即从分析油水混合液粒度分布入手,综合考虑污水的物化参数、分离装置结构参数和处理量,建立重力分离数学模型,直接计算排放的含油量．本文介绍了用 MIAS—2000图象分析系统测定油粒分布、用三种常见分离装置进行数据实验论证的情况,实验数据表明：数模在工程上应用是可行的,具有足够准确性．本文还介绍了用数模进行分离装置计算机设计的专用软件及应用。更多还原

【Abstract】 Gravity separation is the most conventional technique frequently used for oily wastewater separating.But the traditional design with this concept,no matter at home or abroad,only deals with the limit particle dimensions,not with the oil content of the dis- charged wastewater.The authors put forward in the paper a new concept which starts from analysis of particle distribution in the oil-wastewater mixture,give a complex consideration to both the physico-chemical parameters of the oily wastewater and the structure and capacity of the separating device,and then set up a gravity .separating mathematical model.Thus oil content of the discharged wastewater can be directly calcuated.The paper also gives an intro- duction to the measurement of the oil particle distribution in the discharged wastwater by the MIAS-2000 Image Analysis System and the verification of the mathematical mode by test da- ta obtained from three different conventional separating devices.Test results show that the application of mathematical model is feasible and precise enough.Software with the mathe- matical model specially for the design of separating devices is also introduced in the paper.更多还原
