Zusammenfassung:	The present invention relates to a method for operating an SCR system including one discharge pump (51) and two or more metering supply valves (11, 12). More specifically, when the one or more metering supply valves (12) do not have an error and the other metering supply valves (11) have an error, the metering supply of a reducing agent solution through the one or more metering supply valves (12) without the error is performed. 본 발명은 하나의 토출 펌프(51) 및 2개 이상의 계량 공급 밸브들(11, 12)을 포함하는 SCR 시스템의 작동 방법에 관한 것이며, 이때 하나 이상의 계량 공급 밸브(12)에 에러가 없고 나머지 계량 공급 밸브들(11)에는 에러가 있는 경우, 에러가 없는 하나 이상의 계량 공급 밸브(12)를 통한 환원제 용액의 계량 공급이 실행된다.
