摘要
在2005年4月-2005年12月对东湖水库的理化因子进行了研究,结果如下:春,夏,秋,冬四季ALK分别为2.24mmol/L,2.15mmol/L,2.08mmol/L,2.29mmol/L。TH分别为2.19mmol/L,2.04mmol/L,2.04mmol/L,2.25mmol/L。COD分别为23.23mg/L,24.92mg/L,24.92mg/L,15.50mg/L。NH4+-N分别为0.334mg/L,0.26mg/L,0.64mg/L,0.29mg/L。NO3--N分别为0.165mg/L,0.32mg/L,0.27mg/L,0.22mg/L,NO2--N分别0.070mg/L,0.03mg/L,0.051mg/L,0.08mg/L。∑N分别为7.26mg/L,12.04mg/L,12.89mg/L,7.00mg/L。∑P分别为0.07mg/L,0.19mg/L,0.30mg/L,0.025mg/L。N:P(总质量比)分别为134.75,63.25,43.25,284。
From Apr. 2005 to Dec. 2005, we make a study on Physics - chemistry factors of the Donghu Lake Reservoir. The results are as follows ： the ALK of spring, summer, autumn, winter were respectively 2.24mmol/L, 2.15 mmol/L, 2.08 mmol/L, 2.29mmol/L;The TH were 2.19mmol/L,2.04mmol/L, 2.04mmol/L,2.25 mmol/L. The COD were 23.23mg/L,24. 92mg/L,24.92mg/L, 15 . 50mg/L. The NH4^＋- N were 0. 334mg/L,0.26mg/L,0.64mg/L,0.29mg/L. TheNO3^-N were 0. 165mg/L ,0.32mg/L,0.27mg/L,0.22mg/L. The NO2-N were 0. 070mg,/L,0. 03 mg/L,0.051 mg,/L,0.08mg,/L,and the TN were 7.26mg/L, 12.04mg/L, 12.89mg/L ,7.00mg/L. While, the TP were 0.07mg/L ,0.19mg/L ,0.30mg/L,0.025mg/ L. The N ： P（ total quality rate） were 134.75,63.25,43.25,284.
