通过对《地表水环境质量标准》(GB3838-2002)中总氮指标与硝酸盐氮、亚硝酸盐氮、氨氮和有机氮关系的分析,以及对总磷标准的不一致性的探讨,论述了总磷、总氮在评价饮用水源中存在的问题,提出应把总氮指标作为集中式生活饮用水源地补充项目标准限值,恢复硝酸盐氮、亚硝酸盐氮作为地表水环境质量标准基本项目标准限值;修改总磷标准值.
通過對《地錶水環境質量標準》(GB3838-2002)中總氮指標與硝痠鹽氮、亞硝痠鹽氮、氨氮和有機氮關繫的分析,以及對總燐標準的不一緻性的探討,論述瞭總燐、總氮在評價飲用水源中存在的問題,提齣應把總氮指標作為集中式生活飲用水源地補充項目標準限值,恢複硝痠鹽氮、亞硝痠鹽氮作為地錶水環境質量標準基本項目標準限值;脩改總燐標準值.

Based on“the surface water environment quality standard”(GB3838-2002)total nitrogen index and nitrate nitrogen,nitrite nitrogen,ammonia nitrogen and organic nitrogen relationship analysis,And the total phosphorus standard inconsistency discussion,This paper discusses the total phosphorus and total nitrogen in the evaluation of the problems existing in the drinking water.Puts forward that we should put the total nitrogen index as a centralized life drinking water source area of supplementary project standard limit,restore nitrate nitrogen,nitrite nitrogen as the surface water environment quality standard basic project standard limit ;Modified total phosphorus standard value.
