姚江引水配套工程对慈溪市城区河道水质改善效果分析

River Water Quality Improvement Analysis for Yaojiang Water Transfer Engineering

为了分析姚江引水后城区水质改善效果，建立数学模型对各引水方案的水质变化情况进行模拟计算和分析。结果表明，各方案对城区水环境的改善都有明显的效果，但各区域的改善程度有所差异，改善效果受姚江来水水质影响较大。论文认为全面改善城区水质的根本出路在于污染源治理。增加引水水源对改善城区河网水环境效果更为显著，多水源引水使水量水质分布更为合理，影响范围更加全面。

In order to analyze the water quality improvement after Yaojiang Water Transfer Engineering, several mathema- tical equations were established to simulate the water quality changes. The results show that, each engineering scheme was useful to water quality improvement with different effect, and it is related to the source quality from Yaojiang. Besides, it is suggested that, pollution regulation is the key step to improve river water quality. Also, another method is to increasing source for water transfer, which leads to a more reasonable distribution of water quantity and quality.
