Abstract

본 고안은 표준 활성슬러지법의 운전방법개선에 관한 것이다. 기존의 부유 미생물을 이용한 처리법에서 운전관리의 핵심은 미생물에 의한 유기물의 제거와 슬러지의 침강성이며 부차적으로 슬러지의 처리, 처분이나 포기 강도 등과 같은 경제성 문제라고 할 수 있는데, 본 고안은 운전방법을 기존의 방법인 계속포기가 아닌 간헐포기를 통하여 포기조내의 미생물의 종조성을 변화시키고 이로 인하여 유기물의 제거효율의 증대, 포기를을 위한 energy절감, 슬러지 침강성 개선 및 슬러지 전환율 감소 등으로 저 에너지 소비와 더불어 그효율성을 높이고자 함이다The present invention relates to an improvement of the operation method of the standard activated sludge method. In the existing treatment method using suspended microorganisms, the core of operation management is the removal of organic matter by the microorganisms and the sludge settling and secondary economic problems such as sludge treatment, disposal or abandonment strength. Through intermittent aeration rather than continuous aeration, the composition of microorganisms in the aeration tank is changed, thereby lowering energy consumption by increasing organic removal efficiency, reducing energy for aeration, improving sludge sedimentation, and reducing sludge conversion rate. To increase efficiency

Claims (1)

활성슬러지법에 의한 유기물(BOD)을 처리함에 있어 1개의 포기조에서 포기방식을 포기와 무포기를 일정 시간 간격으로 반복하여 처리수의 수질개선(S- COD, T-COD), 슬러지 침강성의 개선, 슬러지 발생량의 감소및 포기를 위한 에너지의 절감 등을 꾀하고자 하는 즉 간헐포기 운전방법In the treatment of organic matter (BOD) by activated sludge method, the aeration tank is abandoned in one aeration tank and the aeration system is repeated at regular intervals to improve the water quality (S-COD, T-COD) and sludge sedimentation of treated water. To reduce the amount of sludge produced and to save energy for aeration ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
