摘要：

Swine wastewater containing high concentration of phosphorus (P) and nitrogen (N) was treated by struvite precipitation method. The pH showed to have strong influence on N and P removal, whereas the excess of ammonia in the reaction medium did not show influence. The precipitated crystals were identified and analyzed by X-ray diffraction (XRD), thermogravimetric analysis (TGA), atomic force microscopy (AFM), and surface area (BET) revealing that there was the formation of a pure and crystalline phase mesostructured at pH 9.5 with an average crystal size in nanometric scale.
