文档介绍：n, Chan Ba River Chan San Lang Cun Wei ba - into the mouth and the intersection of San Lang Cun, three section most prone to eutrophication;
(3)The simulation results, the relative error of ammonia nitrogen, nitrate nitrogen, orga nic nitrogen, total nitrogen and dissolved oxygen less than 40% accounted for 86%, 87%,9 3%, 73%, 85%, are greater than 60%, achieve the applicable conditions of the model, the feas
ibility and applicability of the model is proved;
(4)According to the simulation results to demonstrate, water quality grades of evaluatio n andranking and measured results of the evaluation are basically the same, prove that themo
del can be used as a predictive model of river pollution, providing valid data forwatershed pollution control;
