| Abstract: | The analytical solution of the heavy metal transport model is studied.In the model,the total heavy metal(including both particulate and dissolved heavy metal) concentration is unknown.Based on some assumptions,two new analytical solutions are obtained under two special moving bed conditions,namely pure deposition process and pure erosion process.The result could be used to verify and modify the mathematical model. |
