Growth Properties of Typical Water Bloom Algae in Reclaimed Water
再生水水质环境中典型水华藻的生长特性

Based on Algal Growth Potential Test, the water bloom risk of reclaimed water was studied. Microcystis aeruginosa was proved as the main algae under the experimental conditions in this study. In 3 kinds of secondary effluent(A2O, Oxidation Ditch and Activated Sludge), its maximum density could attain above 106 cells·mL-1, and the specific rate was above 0.39 d-1. Advanced treatment (A2O-Ultrafiltration Membrance Filter-Activated Carbon and Chlorine Disinfection) did not reduce the growth potential of Microcystis aeruginosa. The effects of initial concentration of phosphorus in reclaimed water on maximum density(Kmax) and population growth rate(Rmax) of Microcystis aeruginosa can be described with Monod equation.
