摘要
根据有机物与氧反应的化学平衡，建立了计算不同类型有机物理论化学耗氧量的通用数学模型，计有三种表式：有机物摩尔理论ＣＯＤ；单位质量有机物理论ＣＯＤ；体积为Ｖ升、理论ＣＯＤ浓度为Ｃｍｇ／Ｌ的有机化合物溶液所含该有机化合物的量（ｘ，ｇ）。对大多数模型进行了实验验证，模型计算值与实测值间的最大相对误差在４％左右，说明这些模型推导合理。
Mathematical calculation models of the chemical oxygen demand for different types of organic compounds have been established by chemical equilibrium of their reactions with oxygen. The following types: 1 mole theoretical COD of organic compounds;2 theoretical COD of unit quantity of organic compounds;3 quantity(g)of organic compounds in the solution of valume V liter and concentration C mg/L。For a lot of models, experimental checks have been made, showing that measured values are well conformed to these calculated values with maximum relative error about 4%, so that the established models are correct.
