摘要
扩散系数D和BOD动力学常数K对稳定塘的设计、运行与评价具有重要意义,本文通过放射性示踪法,利用闭口反应器的离散化理论示踪剂脉冲响应曲线,对试验数据进行逼近,获得扩散系数,并由此提出扩散系数的近似估算公式。稳定塘的BOD动力学常数K目前尚没有较为公认的实验测定方法,本文根据稳定塘的特点,提出了实验测定方法。
The diffussion coefficient D and BOD kinetic constant K play a significant role in the design, performance and evaluation of waste stabilization pond. In this paper, through radioactive tracing method using theoretical discrete function of tracer pulse-response of close-opening reactor, the data of tracer test were approximated to obtain the diffussion coefficient; and therefore, the approximate expressions of diffussion coefficicnt were presented. There has not yet a recognized experimental measuring method for the BOD kinetic constant K of watse stabilization pond, and a measuring method is presented here.
