Abstract:

The wastewater treatment by Chlorella vuganis under light and dark condition,and by algae-bacterium system under dark condition were studied,the Chlorella vuganis’s sustainable growth under dark condition was also studied.The results showed that the removal of COD under dark condition was better than light condition,but TN&TP were on the contrary.Chlorella vuganis played a key role in removal COD,TN,TP in the mixed system of Chlorella vuganis and activated sludge when stationarily incubated under dark condition.However,activated sludge played a key role in removal COD,TN,TP in the mixed system when shakingly incubated under dark condition.What’s more,the mixture of algae and bacterium couldn’t have an effect on mutualism and improved the efficiency of wastewater treatment,and Chlorella vuganis could grow and treat wastewater sustainably under dark condition.
