摘　　要：地下水人工回灌堵塞问题的产生与回灌水质、入渗介质的矿物成分及颗粒组成特征等多种因素有关,通常根据成因将堵塞分为物理堵塞、化学堵塞和生物堵塞3种类型。大颗粒悬浮物的物理堵塞效应与机理的研究比较成熟,但对于中间颗粒,尤其是胶体颗粒物的堵塞作用机制的研究还相对比较薄弱;化学堵塞的机理复杂,影响因素众多,水文地球化学模拟技术在化学堵塞机理的研究中显示了良好的应用前景;生物堵塞主要由回灌水中细菌和藻类等微生物的繁殖和代谢导致,大量的研究集中在细菌方面,对藻类引起的堵塞问题研究尚不深入;多种堵塞的相互作用过程和作用机理是目前研究的难点问题。堵塞预测的方法主要包括3种:①指标法(如MFI、悬浮物浓度、浊度、AOC、BFR等),简单实用,但不能对堵塞演化过程进行描述或对堵塞程度进行定量表达;②经验公式法,受特定场地的条件限制,难以直接推广和利用;③解析公式法,对堵塞机理的表达更加科学、合理,但模型的建立与求解难度较大。通过合理的水质预处理技术和合理的回灌工艺,可以有效延迟堵塞发生的时间、减缓堵塞累积的程度。开发快速、高效、简单的堵塞处理技术对于延长工程使用寿命和降低经济成本具有重要的现实意义。The generation of clogging problem during artificial recharge of groundwater has something to do with the quality of recharge water source, mineral and grain characteristics of aquifer. According to the formation reason, clogging is generally divided into physical, chemical and biological types. Physical clogging generated by large particles was understood very well, but the clogging mechanism of intermediate and colloidal particles were not very clear. The mechanism of chemical clogging, which has lots of influence factors, is very complicated. The geochemistry modeling method will be a powerful tool to study the chemical clogging process. The biological clogging was induced by growth and metabolizable products of microbiology bodies in recharge water sources. Most of researches focus on the bacteria clogging, but much less on the algae clogging problems. During actual artificial recharge process, several clogging types usually take place together, but the predominant type is different in different time and space. Therefore, the interaction process and its mechanism is one of the difficult problems. There are three methods to predict clogging process ： the first one is specific indexes, such as MFI, concentration of suspended solid, turbidity, AOC and BFR, etc. This kind of method is much easier to use, but it can not describe or quantify the evolution process. The second method is experiential way, which is limited by specific field sites, and hard to use directly. The third method is analytic model, which is more scientific and reasonable than above methods, but it is hard to set and solve the analytical model. With appropriate pre-treatment of recharge water quality and recharge technologies, the taking place time of clogging can be delayed and the clogging degree can be lighten. Developing the rapid, efficient and simple technologies is very useful to prolong the longevity of recharge facilities and to reduce the economic cost.
