摘要: |
建立了饮用水中微生物、可同化有机碳(AOC)随时间变化的动力学模型;根据饮用水中微生物、AOC、余氯三者随时间变化的实验数据,校核了模型参数,并且验证了该模型的可靠性;实验结果表明:前期由于余氯的氧化作用,AOC随时间快速增加,后期AOC作为微生物生长的有机底物,被缓慢消耗;结合模型,可从理论上证明,存在一个最佳的初始余氯投加量,使得终点时刻微生物的浓度恰好满足水质标准要求,这对于水厂运行成本管理具有一定参考价值。 |

Abstract: |
A dynamic model of microorganism and assimilable organic carbon(AOC) is proposed in the drinking water. According to the real time experiment data of microorganism, AOC, free chlorine, parameters in the model are checked and the reliability of the model is verified. The experiment results show that the concentration of AOC increases rapidly as time goes by at earlier stage for the oxidation of free chlorine, while in the later stage, AOC is slowly consumed in the progress of microorganism growth as organic food. By using the model, it can be proved that there is optimum initial free chlorine dosage so that the concentration of microorganism meets the requirement of standards at the ending time. It is useful for drinking water plants to save running cost. |
