目的通过对鸭绿江中上游水的监测、分析、统计、评价,研究该水域水质理化特征和季节变化动态。方法按环境保护总局HJ/T 52-1999《水质河流采样技术指导》采集水样,按GB/T 5750-2006《生活饮用水标准检验方法》进行检测。结果鸭绿江水域基本处于良好状态,pH值在7.0~8.11之间,水质略偏碱性。硝酸盐氮含量差异较大,三道沟含量最高(平均2.10 mg/L),砬子河最低(平均0.28 mg/L)。结论该水属钙型软水,经净化消毒处理后,可以作为人类生活饮用水水源及珍稀水生生物栖息地。
Aim To monitor, analyze, count and evaluate the water quality in the middle and upper reaches of the Yalu River and study the physical and chemical characteristics and the seasonal dynamics of the water quality in the middle and upper reaches of the Yalu River. Methods Water samples were collected according to HJ / T 52-1999 “Technical Guidelines for Water Quality River Sampling” issued by Environmental Protection Administration, and tested according to GB / T 5750-2006 Standard Test Method for Domestic Drinking Water. The results of the Yalu River waters in good condition, pH value between 7.0 ~ 8.11, the water slightly alkaline. The content of nitrate nitrogen varied greatly, with the highest content of the three channels (average 2.10 mg / L) and the lowest (0.28 mg / L). Conclusion The water is a calcium soft water, after purification and disinfection, can be used as human drinking water source and rare aquatic habitat.
