中文摘要：
为确定陆水水库自来水厂的最佳取水深度,利用水质垂直剖面自动监测系统在陆水水库坝前选定断面,连续进行了近1 a的监测。根据监测资料分析了陆水水库坝前断面垂向水质随季节性变化所呈现的分层现象。结果表明：水库坝前断面水质参数在当年11月到次年2月为混合期,无显著分层现象;3月到10月为分层期,出现分层现象;表层水体受光合作用影响,易爆发蓝藻,深层水体浊度较高。因此,水厂最佳取水深度为水下5~6 m范围。
英文摘要：
In order to determine the most optimal water intake depth of Lushui waterworks in Lushui Reservoir, by using verti- cal water quality automatic monitoring system, the water quality at the selected cross - section in front of Lushui Reservoir Dam was continuously monitored for almost a year. According to the monitored data, the water quality stratification with seasonal varia- tion at the cross - section is analyzed. The results show that the water quality mixing period is from November to next February and no obvious water stratification occurs; the water quality stratification period is from March to October, the water stratification occurs ; influenced by the sunshine photosynthesis, the surface water body is prone to blue - green algae outbreak and the turbidi- ty of deep water is high. The most optimal water intake depth is 5 to 6 m under the water surface.
