组合推流反应器模型用于黑臭水体需氧量计算
|
摘要
曝气复氧是黑臭水体治理的有效方法。建立了组合推流反应器模型,并用它对黑臭水体需氧量及水质进行预测,结果表明,该模型能较精确地计算出黑臭河道需氧量和水质变化趋势。
Aeration oxygenation is an effective way to control black odor water. Combined plug-flowmodel was established to calculate oxygen demand and water quality prediction of black-odor in this paper. The results showthat oxygen demand and water quality prediction were obtained accurately base on this model. The results showthat the model can accurately calculate the changing trend of oxygen demand and water quality in the black and smelly river.
