| Abstract: |
| In order to investigate the correlation between algae propagation and physico-chemical factors for reservoir water,the algae propagation was modelled and the factors were monitored under the microcosm environment for building regression equations. The linear matrix based on the biomass of anabaena(ACD),microcystis(ACM) and algae(AC) in moderate eutrophic situation was built. Results showed that the reservoir is phosphorous-limited and relative to total phosphorous (TP) and temperature. The prediction equations based on TP and temperature can predict algae concentration variations. The prediction equations bulit under microcosm conditions can help water plants predict algae concentrations and adjust water treatment processes according to the equations’results. |
