摘要
抽水蓄能电站水库蓄水运行后,水体滞留时间增加,污染物不断积累。为了更好地了解抽水蓄能电站水质状况,以浙江天荒坪抽水蓄能电站为例,采用模糊数学评价方法,并引入隶属度的概念。结果表明:天荒坪抽水蓄能电站水质状态良好,上库水质与下库水质差异小,营养水平分布较均匀,均在中营养状态或贫营养状态,与富营养化综合指数评价法评价的结果一致。由此可见,模糊数学评价法反映水质级别的连续性及各因子共同作用下的水质状况,可用于抽水蓄能电站水质评价。
The water retention time is increased and the pollutants is acumulated after Pumped Storage Power Station reservoir water running. To better understand the water quality of pumped storage power station,The pumped storage power station of Zhejiang Tianhuangping as the goal use fuzzy mathematical evaluation method to assess and introduced the concept of membership. The results showed that: Tianhuangping pumped storage power station is good quality,upper reservoir water quality and lower reservoir quality is smiliar,more uniform distribution of nutrient levels,both in middle nutritional status or poor nutritional status,and eutrophication composite index evaluation method evaluation results are consistent. Thus,the fuzzy mathematical evaluation method reflects the continuity of the water quality of each factor under the combined effect of water quality levels,and pumped storage power station can be used to evaluate water quality.
