Effect of Chlorella Pyrenoidosa on Treatment of Wastewater from Pig-farms

The study was to test the ability of algal strain Chlorella Pyrenoidosa on treatment of pig-farms wastewater.The best effect was observed in 50% concentration pig-farm wastewater treatment(COD,TN and TP was respectively 296 mg/L,64 mg/L and 7 mg/L) with the Chlorella pyrenoidosa: the growth rate of microalgae was respectively 0.029 g/L and 0.016 g/L in first 2 days and 4 days,the remove rate of COD,TN and TP was respectively 80.07%,79.69% and 87.14%.The results of study indicated that algal strain Chlorella Pyrenoidosa is an agent for mitigation of pollution load.
