| 摘 要： | 城市再生水景观回用的主要问题是水体富营养化导致水华的暴发。为了抑制藻类的大规模生长,需要提前采取预防措施,以便将有可能爆发水华的藻类及时杀死或除去。目前,人们已经对景观水体中常见藻类的生长规律做了深入的研究,发现水体中藻数量(藻密度)的多少与水体的pH值和DO值的变化有密切而相对稳定的关系。通过在线实时监控pH值和DO值,找到△pH、△DO与藻类生长之间的关系,并结合pH、DO、温度、正磷酸盐和总氮等指标,实现实时识别和预测水华爆发的目的。

| Abstract: | Water bloom is easy to breakout in scenic water,which utilizes reclaimed water as source water.Developing warning technology is one of the effective methods to control water bloom.It had been found that pH and DO were closely rehated to alga quantity by other researcher.The relation of alga growth and monitoring data(△DO △pH) was researched in this paper to forecast water bloom.Except for △DO and △pH,pH,DO,temperature,PO43-and TN should be included in warning technology system of water-bloom. |
