Description
Claims (3)
- 오·폐수 처리용 활성오니 영양제의 제조방법에 있어서, (1) 음식물 찌꺼기로부터 유리수분 만을 제거하여 전체 수분함량을 40-60%(w/w)로 조정하는 단계, (2) 고온성 세균인 바실루스 스테아로서모필러스균류를 배양하여 40-80℃에서 증식 가능한 발효균체를 제조하는 단계, (3) 발효교반기에 상기 단계(1)에서 처리된 음식물 찌꺼기와 단계(2)에서 만든 발효균체 200-400ppm를 넣고 일정한 속도로 교반하면서 80℃이하의 온도에서 수분을 유지하면서 70-90분간 서시히 가열하여 발효시키는 단계, (4) 발효교반기의 내부온도를 83-98℃까지 상승시키고 90-110분간 온도를 유지하면서 최종 수분율이 10%이하가 될 때까지 건조시키는 단계, (5) 발효, 건조된 음식물 찌꺼기를 44-55℃사이로 냉각시킨 후 10메쉬 체를 통과시켜 분말상의 영양제를 제조하는 단계를 포함하는 것을 특징으로 하는 오·폐수처리용 활성오니 영양제의 제조방법.
- 제1항에 있어서, 상기 단계(1)에서 수분함량 조정을 위하여 수분조절제로 쌀겨를 첨가하는 것을 특징으로 하는 오·폐수처리용 활성오니 영양제의 제조방법.
- 제1항에 있어서, 요소 3%이하, 황산제일철 0.05%이하, 황산마그네슘 0.1%이하를 첨가하는 단계를 더 포함하는 것을 특징으로 하는 오·폐수처리용 활성오니 영양제의 제조방법.
