Abstract

본 발명은 폐수처리용 영양제의 제조방법에 관한 것으로, 본 발명의 영양제 제조방법은 고온성 세균인 바실루스 스테아로서모필러스균을 배양하여 고온에서 증식 가능한 발효균체를 만들어 음식물 찌꺼기에 접종하여 고속발효 및 건조시켜 체분리하는 것에 의해 제조되며, 이와 같은 구성의 본 발명의 의하면 활성이니 미생물의 생장속도를 크게 증대시켜 오염된 물의 정화 효율을 크게 향상시키며 그 자체로도 오염된 물이 정화적용을 수행하는 오·폐수 처리용 활성오니 영양제를 단기간에 제조할 수 있게 된다.The present invention relates to a method for preparing a nutrient for wastewater treatment. The nutrient preparation method of the present invention is a high temperature bacterium, Bacillus stea, by culturing Mophilus bacteria to make fermentable bacteria that can be grown at high temperature, and then inoculated in food wastes for fast fermentation and It is prepared by drying to separate the sieve, according to the present invention of such a configuration is active because it greatly increases the growth rate of microorganisms, greatly improves the purification efficiency of contaminated water, and the contaminated water itself performs purification application Activated sludge for wastewater treatment can be manufactured in a short time.
