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V(出水)∶V(地下水)=1∶5混合对冬小麦-夏玉米轮作系统连续进行3年小区灌溉试验,地下水中总氮、铵态氮、硝态氮和亚硝态氮等指标的监测结果表明:(1)厌氧水不同灌溉量条件下地下水中4种氮素含量总体呈现高量厌氧水(Ha)>中量厌氧水(Ma)>低量厌氧水(La)的变化趋势;(2)混水灌溉处理地下水中4种氮素含量均呈V(原水)∶V(地下水)=1∶5混合(Tog)>V(厌氧水)∶V(地下水)=1∶5混合(Tag)>V(仿生态塘水)∶V(地下水)=1∶5混合(Teg)的变化趋势。文章的研究能够为制定合理的猪场灌溉制度提供数据支撑。The effluents from anaerobic tank has been utilized as irrigation water for 3 years in the area where maize-wheat rotated.The effect of irrigation amount on the content of nitrogen species in groundwater was investigated in this experiment.To evaluate the effect of irrigation water type,the untreated livestock wastewater,the effluents from anaerobic tank and the effluents form artificial eco-pond were used as irrigation water,respectively.And all the water has been diluted into 1/5 with groundwater before used.The concentrations of total nitrogen,ammonia,nitrate and nitrite were monitored in the experimental period.The results showed the content of all nitrogen species increased with the irrigation amount.In addition,more nitrogen species of the groundwater where the effluents from anaerobic tank was used was observed relative to that of the groundwater where the untreated wastewater was used.Moreover,the effluents from artificial eco-pond lead to the minimal nitrogen concentration in comparison with other two treatments.
