Abstract

A process on crystallized precipitation of ammonium by adding magnesium salt and phosphate was carried out to improve C/N ratio in swine wastewater. After completion of crystallized precipitation of ammonium, an intermittent aeration process with aeration and nonaeration periodsalternated at interval of 1:1 hr day(-1) is used for the improved swine wastewater (T-N/BOD=0.14: BOD=8200 mg/liter and T-N=1166 mg/liter). The results obtained from the experiment show that the removal ratiosof T-N and NH4-N are 91% and 99%, respectively. T-P is not removed, while the removal ratio of PO4-P is 60% as 3% of CaCl2 liquid is added. The results also indicate that dilution with water is effective to improve the removal of phosphorus even if raw swine wastewater contains high concentrations of T-N, T-P, BOD, and TOC.
