半封闭性港口化学需氧量数值模拟

从陆地流入港内的营养物质及其它有这在污染物滞留在港内，经生物化学等反应，生成新的污染物，使港内水质恶化。本文根据滞留在港内这些有机物及无机物的转换，建立了模拟半封闭性港口ＣＯＤ浓度分布的三维数值模型。应用该方法可定量地描述ＣＯＤ浓度在时间和空间上的分布状态，进行水质污染预报和评价。

The Mathematical Simulation of Chemical Oxygen Demand in Semi-enclosed Port

The nutrient matters from the land area flowing into the port and other harmful pollutants staying at the port can produce new pollutants through biochemical reactions, thus,making water quality become worsened within the port. Based on the conversion of these organic and inorganic matters staying at the port, a 3-D model is established to simulate the distribution of COD concentration in the semi-enclosed port. This method can be used to describe the time and spacial distribution states of COD concentration for carrying out the prediction and assessment of water pollution.
