摘要：
[Objective] To study algae harvesting in the roof water tanks of Huangpu district and the seriousness of pollution.[Methods]20 roof water tanks of multi-storied buildings were taken as the sample group and anther 2 samples as the control group. Observation time was one year. And number of algae under the factors such as temperature,light intensity, PH, nitrogen-phosphorus, ratio turbidity oxygen-consumption,and water-consumption,etc were analysed. [Conclusion]The degree of the algae pollution in the roof water tanks is lowered.
