摘要

Microalgae can be used not only to produce many products for people, such as food, bio-oil,and health care products, but also to purify water by absorbing nutrients from the waterbody.In this study, two kinds of microalgae were used to clean ammonia nitrogen and phosphorus existing in wastewater through a two-stage cultivation process.In the first-stage cultivation,Chlorella vulgaris (C.vulgaris) was cultivated under a light intensity of 170 μmol m-2 s-1 and cycle of 12 h light and 12 h darkness in a diluted effluent from anaerobic digestion of poultry manure at 28℃.The C.vulgaris was then harvested by ultrafiltration (UF) membrane.In the second-stage cultivation, the water harvested from UF membrane was used to cultivate Spirulina platensis (S.platensis) by adding Zarrouk.With a small volume of algae broth, harvesting algae with membrane costs less energy, but with a large amount of microalgae loss.At a lower ammonia concentration (8-16 dilution ratio), S.platensis could grow well and remove ammonia completely.The two-stage cultivation of microalgae not only produced more algae biomass, but also reduced total phosphorus (TP) and total nitrogen (TN) in wastewater.
