摘要
通过对呼伦贝尔市岭东河流(甘河、诺敏河、阿伦河、雅鲁河)的水质监测和分析,结果表明:除pH值和氨氮外,其余各项水质指标季节变化明显。化学需氧量、总磷和高锰酸盐指数的最高值出现在7—9月,最低值分别出现在1月、2月和12月,而且不同河流是不同的。总氮的最高值出现在1月、2月和12月,冬季高于夏季。4条河流的pH值全年均达到了Ⅲ类水质标准,化学需氧量、总磷和高锰酸盐指数,除了7-9月外,其余月份均达到Ⅲ类水质标准。
Water quality monitoring&analysis of Lingdong Rivers(Ganhe River,Nuomin River,Alun River,Yalu River)in Hulunbeier in different seasons were analyzed.Result shows that in different seasons,in addition to pH&ammonia nitrogen,the seasonal changes of the rest various water quality indicators are obvious.The highest values of chemical oxygen demand,total phosphorus&permanganate index appear in July-September,and the lowest values appear in January,February and December respectively,and different rivers are different.The highest value of total nitrogen occurs in January,February&December,and it is higher in winter than in summer.The pH values of the four rivers all reach ClassⅢwater quality standards throughout the year.The chemical oxygen demand,total phosphorus&permanganate index all reach ClassⅢwater quality standards in the remaining months except July to September.
