碩士 / 國立中央大學 / 環境工程研究所 / 104 / The purpose of this study was to investigate the nitrogen and phosphorus removal efficiency from wastewater by immobilized microalgae, which mainly used to overcome the problems of collecting and separating Chlorella sp. after wastewater treatment. The experiments were carried out with synthetic as well as real wastewater in batch modes under different operation parameters.
The results of synthetic wastewater tests indicated that the maximum 70.5% of ammonia removal efficiency was obtained under the circumstances of 1.0 g/L initial algae concentration and 10% carbon dioxide concentration in gas flow. In actual wastewater tests, the results revealed that the immobilized algae could uptake nitrogen and phosphate from final effluent and secondary treated wastewater. In addition, the results also showed that the greatest nitrogen and phosphorus removal efficiency was 95% and 99%, respectively, by immobilized microalgae in “A Factory” wastewater. Finally, the analysis of oil content in microalgae after the experiment of wastewater treatment verified that algae still have great potentiality of being the biodiesel feedstock.
