Beschreibung
Zusammenfassung:	The present invention relates to a method of recovering phosphoric acid from fermentation liquor or wastewater thereof, and to a process of recycling the phosphoric acid recovered for fermentation. More specifically, the method of the present invention comprises the following steps: (a) a concentration step; (b) a pH regulation step; (c) a crystallization step; and (d) a recycling step. According to the present invention, phosphoric acid can be recovered from fermentation liquor or wastewater thereof without using organic solvents, and can be recycled in a fermentation process. Thus, the present invention does not incur an additional cost due to the use of solvents, and thus may be extremely useful in fermentation processes. 본원은 발효액 또는 이의 폐액으로부터 인산을 회수하는 방법 및 회수한 인산을 발효에 재사용하는 공정에 대한 것이다.
