【摘要】：随着水库运行时间的延长,水质管理遇到了诸如入库污染物的累积效应,水质要素的多维多相性,水源连通影响等新问题,直接影响供水安全。为此,碧流河水库实施了水库水质综合调查研究,在水质样本采集空间上,补充强化了水库入流河口段和库区特殊断面的样本采集;在采样时间上,除了常规的非冰冻期样本采集,增加了12月至次年3月的冰冻期样本采集与分析;在水质分析样本类型上,除了采集水体样本外,增加了悬浮物和沉积物样本的采样和分析。此外,在大洪水汇入、特低水位、外流域输水初期的特殊时机,也及时收集了不可多得的数据。为水库水质管理提供了重要技术支撑,增强了水库水质管理的科学性和自信心。
[Abstract]:With the extension of reservoir operation time, water quality management has encountered new problems such as cumulative effect of pollutants in reservoir, multi-dimensional and multi-phase of water quality elements, water source connectivity and other new problems, which directly affect the safety of water supply. Therefore, the Biliuhe Reservoir has carried out a comprehensive investigation and study on the water quality of the reservoir. In the water quality sampling space, the collection of samples from the estuary section of the reservoir and the special section of the reservoir area has been strengthened, and the sampling time has been increased. In addition to the conventional unfrozen sample collection, the freezing period sample collection and analysis from December to March of the following year were increased, and the sample type of water quality analysis was increased in addition to the collection of water samples, the samples of suspended matter and sediment were collected and analyzed. In addition, rare data are collected in time at the special time when the flood flows in, the very low water level, and the initial stage of water conveyance in the outer basin. It provides important technical support for reservoir water quality management and strengthens the scientific and self-confidence of reservoir water quality management.
