基于逆建模技术的淮河干流长台关-息县段入河污染负荷评估
Estimation of pollution load in Changtaiguan-to-Xixian section of main stream of Huaihe River based on inverse modeling technology
摘要
Abstract
A distributed source model was established according to the confluence characteristics of the Changtaiguan-to-Xixian section upstream of the Huaihe River, through a case study from 2008. The inverse modeling was conducted based on the Bayesian statistical method. "Hie measured data of the water quality at the studied section were used to calculate the pollution load flowing into the river and the degradation coefficients of the main water quality factors. The results show that the total pollution loads of NH3-N and COD in the study area were 17 000 t per year and 89 000 t per year, respectively. Affected by seasonal non-point source pollution loads, the pollution loads of NH3-N and COD were 657.55 t to 2014.99 t per month and 3 897.73 t to 13311.83 t per month, respectively. The degradation coefficients of NH3-N and COD were 0.356 per day and 0.202 per day, respectively. Trie correlation coefficients between simulated and measured values of NH3-N and COD were 0.943 and 0.979, respectively.关键词
