摘要：

The objective of present research was to investigate the technical feasibility of using Nanchang municipal wastewater as culture media for large-scale cultivation of oil-rich microalgae to produce bio-diesel and treating the wastewater simultaneausly. Collecting the municipal wastewater without any treatment from QingShanhu sewage plant as the culture medium for Chlorella vulgaris growth. The experiment monitored the specific growth rate and biomass yield of Chlorella vulgaris and associated ammonia nitrogen, total phosphorous, COD, TSS, and VSS removal during 10 days. The experimental results showed that the level of nutrients influenced algae growth significantly. The growth rate of Chlorella vulgaris reached a maximum of OD(680nm) 2.856 after 8 days culturing and the algae biomass accumulation rate reached a maximum of 0.0100 gdw.L(-1).day(-1). The oil content of Chlorella vulgaris was 180 mg g(-1) in dry biomass weight. The removel rate of NH(4)(+)-N, TP and COD was 0.6123mg.L(-1).day(-1), 0.0540 mg.L(-1).day(-1), and 2.6387mg.L(-1).day(-1). The TSS and VSS removal rate were 0.0100mg.L(-1)day(-1) and 0.0061mg.L(-1).day(-1) respectively.
