湟水河某监测点氮化物变化规律分析

摘要

[Objective]To master the pollution status of Huangshui River.[Method]A 36 h continuous water quality monitoring in Huangshui River Power District bridge monitoring points was conducted,1 h monitoring 1 times,the concentrations of ammonia,nitrogen and nitrate were determined.[Result]The results of single factor analysis of ammonia nitrogen,nitrite nitrogen,nitrate nitrogen concentration was all day long vary,all day long was the morning of ammonia exceed the standard,it was present morning to morning low,noon to late night higher law.The concentration of nitrogen fluctuates in class Ⅰ to Ⅴ,there were no obvious changes.The concentration of nitrate was up to standard,and there were no obvious changes.[Conclusion]Ammonia nitrogen can represent the relative information of nitrogen compounds content in some extent and can basically reflect the change regulation of nitrogen compounds in water.%[目的]掌握湟水河的污染状况.[方法]对湟水河电力小区桥监测点进行36 h连续水质监测,1 h监测1次,测定氨氮、亚氮和硝氮浓度.[结果]氨氮、亚氮、硝氮单因素分析结果是全天的变化各不相同,氨氮全天超标,呈凌晨到上午较低、中午到深夜较高的规律.亚氮在 Ⅰ~Ⅴ类波动,无明显变化规律.硝氮浓度是达标的,变化无明显规律.[结论]氨氮在某种程度上可以代表氮化合物含量的相关信息,基本能够反映湟水河水体中氮化物的变化规律.
