TP浓度和季节变化对再生水水体中藻类生长的影响

藻类的过度生长是将再生水用于城市景观水体时面，临的难题之一。采用城市再生水，在南方某市开展了以再生水为补水的景观水体的藻类生长模拟试验，重点考察了春、夏、秋、冬四个不同季节以及不同总磷浓度下的藻类生长特征。结果表明，在春、夏、秋季，影响藻类生长的最主要因素是总磷浓度，而在冬季则是活跃的藻种。这一研究成果对于再生水景观水体的运行管理和藻类生长的控制具有一定的参考价值。

Influence of TP Concentration and Season Changes on Algae Growth in Landscape Water Supplemented by Reclaimed Water

The algae bloom is one of difficult problems for the application of reclaimed water to urban landscape water supplement. A simulation study on algae growth in landscape water supplemented only by reclaimed water in a southern city of China was conducted. The study focused on algae growth characteristics at different TP concentrations in landscape water during different seasons. The results show that the key factor influencing the algae growth is TP concentration in spring, summer and autumn, and then changes to the algae species in landscape water in winter. This study result provides a reference for the algae bloom control and management in urban landscape water supplemented only by reclaimed water.
