摘　　要：本文介绍了一种通过脱氮硫杆菌进行自养反硝化来去除地下水中硝酸盐的饮用水深度处理方法。中文对其试验原理、流程和方法作了简要说明,并对去除效果的影响因素进行了分析。结果表明,硝酸盐负荷小于876gNo_8^-—N/(m^3滤料·d)时,去除率接近100%。This paper presents the removal of nitrates from the ground water through the autotriphic denitrification by denitrifying thiobacillus.The experimental principle and process of the advanced water treatment for potable water are outlined, and the factors influencing the removal efficiency are analysed.The results show that,the removal rate is close to 100% when nitrate load is below 876g NO_3-N/(m^3·d).
