Effects of Organic Coexisting Impurities on Phosphorus Recovery from Animal Manure Wastewater by Struvite Crystallization

Abstract:

Struvite crystallization is an efficient method for phosphorus recovery from animal manure wastewater. However, large amount of organic coexisting impurities, contained in animal manure wastewater, might influence struvite crystallization. In this study, the effect of typical organic matter contained in animal manure wastewater, such as butyric acid, fulvic acid, tetracycline, on phosphorus recovery was examined. The following conclusions were drawn: (1) with an increase in butyric acid concentration in animal manure wastewater, phosphorus recovery efficiency did not change significantly; (2) with an increase in fulvic acid concentration in animal manure wastewater, phosphorus recovery efficiency decreased obviously; (3) with an increase in tetracycline concentration in animal manure wastewater, phosphorus recovery efficiency decreased slightly.
