摘要
从季节性差异分析了我国东北某城市两座水源地水库的浊度、CODMn、氨氮、UV254、三卤甲烷生成潜能(THMFP)、叶绿素a的变化规律。结果表明,B水库原水水质要好于A水库,两座水库原水浊度、有机物和三卤甲烷前驱物含量均呈季节性变化;A水库CODMn最高值为6.5mg/L,最低值为2.8mg/L;B水库CODMn最高值为5.0mg/L,全年的最低值0.5mg/L出现在3月;B水库叶绿素a在春夏之交变化较明显,A水库和B水库六个月内叶绿素a的平均值分别为36.53和22.25mg/m3,UV254平均值分别为0.11和0.112cm-1。
Variation of turbidity, CODMn, NH4-N, UV254, trihalomethane formation potential （THMFP） , Chl-a of source water in reservoir A and B of a city in northeast China were analyzed by seasonal difference. The results showed that water quality of reservoir B was better than reservoir A. Raw water turbidity, organic matters and precursors of THMs of the two reservoirs showed seasonal variation. The highest and lowest CODM. in reservoir A were 6.5 mg/L and 2.8 mg/L respectively. The highest CODM. in reservoir B were 5.0 mg/L, and the lowest appeared in March, with the value of 0.5 mg/L. Chl-a in reservoir B changed obviously at the end of spring and beginning of summer. In the two reservoirs, the average of Chl-a were 36.53 mg/m3 and 22.25 mg/m3 respectively, the average of UV254 were 0.11 cm^-1 and 0. 112 cm^-1 respectively, during six months.
