摘要

这项研究提出了一种基于水力调控的方法,用于控制小型水库中产生异萜酮(MIB)的蓝藻的生长,根据长期的野外调查、实验室培养实验、模型构建和现场应用的结果。野外调查发现较长的水力停留时间(HRT)是触发MIB事件的因素之一。培养研究揭示了最大细胞密度、产生MIB的Planktothricoides raciborskii的生长速率和MIB浓度由HRT决定(R2= 0.94,p值 < 0.001),并且可以通过将HRT减少到小于10天来最小化。在此基础上,建立了一个HRT调控模型,并通过野外调查进行了验证,并评估了14个蓝藻属的关键HRT值。通过将HRT减少到5.4 ± 0.8天,低于7.5 ~ 15.0天的临界值,成功地终止了2021年ZXD水库的一个MIB事件。结果表明,该提出的原则可以为HRT调控提供科学依据,已证明是有效和可行的。这种方法避免了对水质的负面影响,不需要额外投资于工程基础设施,并且在某些情况下可以通过改变现有的操作程序来立即应用。因此,基于HRT的调控是一种有前途的策略,可以针对MIB的控制,可能也适用于小型水库中其他蓝藻来源的水质问题。
