摘　　要：应用猪场废水处理工程中产出的厌氧水不同灌溉量和3个处理阶段出水与地下水按体积比1∶5混合对冬小麦-夏玉米轮作系统进行3年的小区灌溉试验,监测地下水的总矿化度及钾、钙、钠、镁等含量的变化。结果表明:(1)地下水中钾含量在厌氧水不同灌溉量条件下呈现高量厌氧水(Ha)>中量厌氧水(Ma)>低量厌氧水(La)的变化趋势,在混水灌溉处理地下水中钾含量均呈厌氧水与地下水1∶5混合(Tag)>原水与地下水1∶5混合(Tog)>仿生态塘水与地下水1∶5混合(Teg)的变化趋势;(2)地下水中钠、钙、镁含量大致呈现低量厌氧水(La)>中量厌氧水(Ma)>高量厌氧水(Ha),仿生态塘水与地下水1∶5混合(Teg)>原水与地下水1∶5混合(Tog)>厌氧水与地下水1∶5混合(Tag)的变化趋势。Three volumes of anaerobic water and the output of three stages of livestock wastewater treatment mixed with groundwater were used as irrigation water three years in the area where maize-wheat rotated.As the monitoring of potassium,calcium,sodium,magnesium concentration in groundwater,the results showed that：（1）The change trends of potassium concentration in groundwater with different volume of anaerobic wastewater was HaMaLa,with the three tragedy of livestock wastewater treatment mixed with groundwater,the tendency of potassium concentration in groundwater was TagTogTeg;（2）The change trends of other three ions concentration in groundwater was LaMaHa with different volume of anaerobic wastewater and TegTogTag with the three stages of livestock wastewater treatment mixed with groundwater.
