| 摘 要： | 海河流域是我国重要流域之一,对其污染及治理的研究显得尤为重要。由2004年-2010年7年的连续数据进行统计和分析,在对海河污染程度现状分析的基础上,发现了溶解氧的浓度与整个水质等级的对应情况。在全部的统计分析数据中,对天津三岔口监测点2010年全年的监测数据进行了进一步分析,其中详细分析了溶解氧、高锰酸盐指数和氨氮三者间的相关性,计算得到回归方程:CODMn=7.308-0.246DO±2.714;NH3-N=2.345-0.173DO±1.18。由相关性分析结果表明,溶解氧浓度与高猛酸盐指数及氨氮浓度呈现显著的负相关性。经过分析得到了在溶解氧分别在3mg/L以下、3～5mg/L、5mg/L以上3种条件下的水质特征。 |

| Abstract: | The Haihe river basin is an important basin in China,thus the study on controlling the pollution in it is critical.Based on the analysis of the current pollution status in the Haihe river,this paper conducted the statistical analysis of the continuous observed data from 2004 to 2010 and investigated the relationship between the concentration of dissolved oxygen and the water quality grade.Furthermore,this paper analyzed the observed data in 2010 at the Sanchakou monitoring station of Tianjin,especially the relationships among the dissolved oxygen,permanganate index,and ammonia nitrogen.Two regression equations were obtained:CODMn=7.308-0.246DO±2.714 and NH3-N=2.345-0.173DO±1.18.The results showed a negative correlation between the dissolved oxygen and permanganate and between dissolved oxygen and ammonia nitrogen,and the water quality was characterized for the concentration of dissolved oxygen at 3,3-5,and 5 mg/L,respectively. |
| Keywords: | Haihe dissolved oxygen correlation statistical analysis regression equation water quality characteristics |
