Recovery of Phosphorus from Feces-and-Urine-Separated Swine Wastewater with Struvite Accumulation Device

CO2 stripping by aeration raised the pH of wastewater in a reactor, and a stainless steel device for accumulating struvite for recovery was submerged into the reactor. This device consisted of four mesh baskets having different heights and diameters. The feces-and-urine-separated swine wastewater and the swine wastewater treated by a solid/liquid separation swine wastewater (S/L SSW) were fed to the reactor. From the swine wastewater, the crystallization efficiency was 65%, and 8.2% crystallized P in the influent was recovered as struvite. From S/L SSW, the crystallization efficiency was 83%, and 26.7% crystallized P in the influent was recovered as struvite. For example, at a PO4P surface load of 2 kg/m, 0. 7-0. 9 kg/m of struvite was recovered from wastewater, whereas from S/L SSW 3kg/m of struvite was recovered. This is because the surface area of accumulation device was enlarged, and because the recovery efficiency was improved by the removal of Suspended Solids (SS) using the S/L separator and raising the pH improved recovery.
