摘　　要：以胶州前韩地下水为例,选用铁粉、活性炭、锯末及其混合物为反应介质,设计6种PRB反应器,探讨了反应介质对硝酸盐降解速率及对环境的影响,以寻求一种廉价而高效的降解地下水中硝酸盐的材料。结果表明,采用PRB技术降低地下水硝酸盐浓度是可行的。零价铁、活性炭、锯末均对硝酸盐有去除作用,当PRB反应器中含有铁粉时能将硝酸盐氮去除90%以上。Taking groundwater of Qianhang in Jiaozhou City for an example, six kinds of PRB reactors are designed by selecting iron powder, active carbon, sawdust and its mixtures as reaction medium. The influence of reaction medium on the nitrate degradation rate and environment is discussed to find a cheap and efficient material for nitrate degradation of groundwater. The results show that the PRB technology is effective for nitrate degradation of groundwater; zero-valent i- ron, active carbon and sawdust have a certain adsorptive effect on nitratel when PRB reactor contains zero-valent iron, it can remove more than 90% of nitrate.
