摘要
为了研究栾城县地下水NO3-N的污染情况及分布规律,采用吸光光度法对所采集的栾城县内17个水井地下水的水样进行分析。结果表明:该地地下水已普遍受到NO3-N的污染。地处排污区洨河流域的地下水NO3-N的污染程度明显高于冶河流域,洨河流域采样点NO3-N平均含量为11.58mg/L,最高值突破63.8mg/L,已经不符合饮用水的健康标准;冶河流域地下水水质状况较好,采样点NO3-N平均含量4.7mg/L。在排污区洨河流域,采样点距离洨河越近,其NO3-N含量越高;在距离相同时,地处土壤、岩层疏松,有矿物存在的采样点NO3-N的含量明显增高。由于污水排放和污水灌溉的原因,致使栾城县洨河流域地下水NO3-N污染十分严重。
In order to research the NO 3-N pollution of underground water in Luancheng County and its distribution,the author used spectrophotometric method to analyze underground water samples from 17 wells within Luancheng County.The results showed that the underground water had been polluted by NO 3-N universally.The NO 3-N pollution in Basin of Xiao River was obviously higher than that in Basin of Ye River,the average NO 3-N content in Basin of Xiao River was 11.58 mg/L,the highest was 63.8 mg/L,which was not suitable for the minimum standard of drinking water;quality conditions of underground water was well in Basin of Xiao River,the average NO 3-N content was 4.7 mg/L.In Basin of Xiao River,the closer samples distance to Xiao River,the higher NO 3-N content;in the same distance,the NO 3-N content was obvious high,which was located in the soil and rock layer loose,the mineral existing.Due to the sewage discharge and the sewage irrigation,in the Basin of Xiao River in Luancheng County,the NO 3-N pollution of underground water was very serious.
