Description
In order to clarify the influence of pH, cation, etc. of solution after simultaneously recovering ammonium, phosphorus and potassium from swine wastewater on biological treatment, the solution was biorogically treated with an intermittent aeration process. An inhibition of TOC and T-N removal was not found although the concentration of Na and Cl exceeded the concentration which was reported to cause inhibition. Even if pH was 9.5, the inhibition was not found. On the contrary, at a pH of 9.5 biological removal of TOC and T-N was promoted. It was considered that simultaneously recovering ammonium, phosphorus and potassium by crystallization from swine wastewater would not hinder biological treatment.
