  • 摘要: 缺水地区再生水补充景观水体具有重要的意义，因此考察不同再生水补水比例条件下的水质变化尤为重要。采用修建人工景观水池的方法，模拟不同再生水补水比例条件下景观水体的水质变化规律。将某水厂的再生水和自来水按不同比例配水作为人工水池的进水和补水，水力停留时间固定为5 d。实验结果表明当该再生水所占比例为75%、50%时，水质恶化最快，100%和25%时由于营养比例失衡，水质恶化速度较慢。此外，叶绿素a的增长主要受氮磷营养盐浓度的影响，并影响着水体的浊度、色度和透明度，进而破坏景观水体的感官指标。
    Abstract: It is meaningful to supply the landscape with reclaimed water in water-deficient areas. In this regard, it is crucial to monitor water quality variations with different ratios of reclaimed water supply. Artificial landscape pools were employed in this study to simulate the changes in water quality for different ratios of reclaimed water. The HRT of the pools was 5 days when the inflow comprised a mixture of reclaimed water and tap water from one WWTP in different proportions. It was found that the water quality deterioration was the fastest when the proportion of reclaimed water was 75% and 50%. On the other hand, the deterioration rate of the pools with 100% and 25% reclaimed water was lower due to the imbalance of nutrients in the inflow. In addition, the concentrations of nitrogen and phosphorus were the main factors contributing to chlorophyll-a accumulation, which in turn influenced the turbidity, color, transparency variation, and eventually, the sensory index of landscape water.
