海河流域污染状况与常规污染指标数据分析
Analysis of Pollution in Haihe River and Its Conventional Indicators
摘要
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.关键词
