荆州城区几个典型水体的检测与分析

选取荆州城区长江、九龙渊、便河等三个特定水体,以自来水为对照,进行了水质分析.结果表明:九龙渊和便河水的碳酸盐碱度值较高,分别为73.0mg/L和22.1`mg/L;九龙渊水的总碱度最高,达到了228.8mg/L;测定了氨态氮、化学需氧量和亚硝酸盐氮的含量,将九龙渊水和便河水的值分别与长江水和自来水进行比较,其氨态氮含量分别高143.2%、583.8%和11.7%、214.1%;化学需氧量分别高564.5%、637.9%和514.7%、582.6%;尤其是亚硝酸盐氮,九龙渊的含量分别是长江水的493.3倍、自来水的1480倍,便河水的含量分别是二者的466.7倍和1400倍.

Detemination and analysis of several representativewater substance in the zone of Jingzhou city

The three of representative water substance in the zone of Jingzhou city,which is consisted of the Yangtze River being bound in Jingzhou city,Jiulongyuan River and Bian River were selected as the water sampling to carried through the water quality analyzing,the control was the running water.The results shown that: The alkalinity of carbonate in the Jiulongyuan River and Bian River were relatively higher,the datewere 73.0mg/Land 22.1mg/L.The total alkalinity was also the topmost in Jiulongyuan River,which reached 228.9mg/L;The results of determination in ammoniacal nitrogen,chemical oxygen demand and nitrite nitrogen were consistently indicated that: the date of Jiulongyuan River and Bian River were all higher than the Yangtze River and the running water,among of those,the content of ammoniacal nitrogen in the two region were higher 143.7%,583.8 and 11.7%,214.1% than the Yangtze River and the running water respectively.Especially in the nitrite nitrogen,the content of the Jiulongyuan River was 493.3 times of the the Yangtze River and 1480 times of the running water,the Bian River was the 466.7 times of the Yangtze River and 1400 times of the running water.
