根据水体扩散理论,建立淮干水质预测相关模型,并进行验证;首次对淮河干流信阳段 NH3-N、COD 的综合衰减系数,复氧系数和耗氧系数等4项开展现场试验及分析,结果表明,引起误差的主要原因是复氧率及光合作用随河流而异,难以准确确定.

Based on the water diffusion theory, a water quality prediction model was established for the main stream of the Huaihe River, and the model validation was performed.Field tests and scientific analysis were conducted to study NH3-N, the integrated attenuation coefficient of COD , the reaeration coefficient, and the oxygen-consuming coefficient of the Xinyang section of the main stream of the Huaihe River .According to the results, the main cause of error is that the reaeration rate and photosynthesis vary with different rivers and cannot be easily determined .
