海报摘要

Green microalgae showed a good growth potential and nutrient removal not only in reference medium but also in unfiltered RAS wastewater, while non-green microalgae performed poorly both in wastewater and in reference medium. The growth and nutrient removal of C. reinhardtii, M. griffithii, and Selenastrum sp. in unfiltered RAS wastewater did not vary between the three light spectra, whereas the three microalgae differed from each other for growth parameters and nutrient removal. Waterfleas (Daphia magna) increased their dry weights 2-4 times when fed with four different green microalgae previously cultivated in filtered RAS wastewater.
