Abstract

본 발명은 탈수 케이크를 이용한 활성슬러지 미생물 식종 방법에 관한 것으로 더욱 상세하게는 활성슬러지법이 채용된 타 폐수 처리 시설에서 발생된 탈수 케이크를 일정량 신설 폐수 처리 시설의 포기조에 투입하여 폐수 처리용 활성슬러지 미생물을 식종하기 위한 방법에 관한 것이다. 본 발명에 따른 활성슬러지 미생물 식종방법은 활성슬러지법이 채용된 타 폐수 처리 시설에서 발생된 잉여슬러지를 소화 공정을 거치지 않고 탈수 공정에서 바고 탈수한 탈수 케이크를 신설된 폐수처리 시설의 포기조에 식종하는 것을 특징으로 한다. 본 발명에 따른 활성슬러지 미생물 식종 방법은 종래의 잉여슬러지법에 비해 운반하여야 할 슬러지의 부피가 20배 이상 감소됨에 따라 운반비가 크게 절갈되고, 15일 내지 20일 정도의 비교적 짧은 기간 안에 정상적인 폐수 처리가 가능할 정도로 활성화되므로 자연증식법에 비해 신속하게 미생물의 활성이 이루어지는 효과가 있다.The present invention relates to a method for seeding activated sludge microorganisms using a dewatered cake, and more particularly, to a wastewater treatment activated sludge by inputting a dewatered cake generated in another wastewater treatment facility employing an activated sludge method into a waste tank of a new wastewater treatment facility. It relates to a method for planting microorganisms. The activated sludge microorganism seeding method according to the present invention is to seed the dewatered dehydrated cake from the dewatering process without passing the excess sludge generated in another wastewater treatment facility in which the activated sludge method is employed in the dewatering process in aeration tank of the new wastewater treatment facility. It is characterized by. In the activated sludge microbial seeding method according to the present invention, the transportation cost is greatly reduced as the volume of sludge to be transported is reduced by 20 times or more compared with the conventional excess sludge method, and the normal wastewater treatment within a relatively short period of 15 to 20 days Since it is activated to the extent possible, there is an effect that the activity of the microorganism is faster than the natural growth method.
