地下水人工回灌颗粒沉积研究进展

Research progress on particle deposition in artificial groundwater recharge

颗粒堵塞是影响地下水人工回灌效率的主要因素,揭示地下水人工回灌过程中引起颗粒堵塞发生发展的颗粒沉积机理规律,为减少回灌堵塞、提高回灌效率的研究提供技术支撑。对已有关于回灌颗粒堵塞现象和颗粒沉积理论机制的研究进行了综述。结果表明:现阶段相关研究不能定量地观测颗粒堵塞的微观物理过程,颗粒堵塞机理与颗粒堵塞现象间的内在联系不完全清楚,跨尺度耦合研究不充分。

Groundwater artificial recharge clogging,mainly represented by particle clogging,is a factor affecting the recharge efficiency mostly.The reveal of the occurrence of macro particle clogging process and the development of micro particle deposition in the process of groundwater artificial recharge can provide technical support for the research of reducing recharge clogging and improving recharge efficiency.These existing research on the engineering phenomenon of recharge particle clogging and the theoretical mechanism of particle deposition are reviewed.It is concluded that the related research in this stage cannot quantitatively observe the microscopic physical process of particle clogging,the internal relationship between particle clogging and macroscopic scale is not completely clear,and the cross-scale coupling research is not sufficient.
