目前国家生活饮用水GB5749-85标准中尚未规定氨氮标准。1960年我省对省生活饮用水卫生标准中规定氨氮不得检出。1982～1989年的监测数据,氨氮合格率仅占30.75％ 目前的有关文献氨氮评价标准均采用WHO提供的标准0.05mg/L。为确定我市自备井水氨氮含量范围,应用百分位数法对我市308口水井氨氮数据进行分析。
Currently the national standard of living water GB5749-85 ammonia nitrogen has not yet provided standards. In 1960, the province’s drinking water health standards in the provisions of ammonia nitrogen shall not be detected. The monitoring data from 1982 to 1989, the passing rate of ammonia nitrogen accounted for only 30.75% of the current relevant literature ammonia standards are used to provide the standard 0.05mg / L WHO. In order to determine the scope of our city’s own well-water ammonia-nitrogen content, we use the percentile method to analyze the ammonia nitrogen data of 308 wells in our city.
