摘要
在不影响拙政园原有景观的前提下,采用人工水力循环措施进行水体修复试验,并结合FLUENT软件对不同工况下的流场模拟计算结果,分析了对水质的改善效果。结果表明:采取水力循环措施可使园林水体的浊度平均下降约4.5NTU,DO平均提高39.1%,CODMn平均下降25%,同时避免了"翻塘"现象的发生,并使水体水质受温度变化的影响减小,水质的稳定性得以增强。
On the premise of not influencing the original landscape of Humble Administrator＇ s Garden, the hydraulic circulation measures were taken to perform a test of water body restoration, and the improvement effect of water quality was analyzed with the calculation results of flow field simulated by FLUENT software under the different operation conditions. The results show that the average turbidity of the water body decreases by 4.5 NTU, the average DO increases by 39.1% and the average CODMn decreases by 25%. Overturning of the water body is avoided. The impact of temperature variation on the water body quality is reduced, and the stability of the water quality is improved.
