Study on N,P removed in culturing wastewater by Chlorella

The study on nitrogen and phosphorus removed in the culturing wastewater by the Chlorella was made.The results showed that the alga can grow well in the water body,and the chlorella can well remove the nitrogen,phosphorus in the water body.After cultivating 4 days,the removal rate of nitrogen is more than 80%,the inorganic phosphorus more than 85% in the water body.Under the normal temperature,illumination,pH,rate N/P 8 is most suitable for growth of the alga.The increasing amount can reach 10 times of initial quantity of chlorella in 4th day.
