     본 발명은 아미노산을 이용한 콩나물의 재배법에 관한 것으로, 콩나물의 고소한 맛을 향상시켜 먹기쉽고, 단백질의 합성에 필요한 필수아미노산을 전부 함유토록 하여 콩나물을 종합식품으로 제공하고자 하는 것이다. 
     나. 발명이 해결하려는 기술적 과제. 
     현재 콩나물의 재배법으로는 1차로 콩을 불리거나 또는 반복적인 분무에 의하여 콩나물을 재배하고 있는 것이고 싹이 나온 이후에 수시로 물을 분무하는 공정으로 제조하는 것이고 이러한 공정 중에서 오염된 물을 사용할 경우에는 콩나물이 썩는 것을 방지하기 위하여 분무 시에 수용성의 항생제나 비료 등을 사용하여 성장속도를 향상시킴으로서 이러한 항생제의 사용이 건강을 해치게 되는 원인이 되는 것이다. 
     따라서 최근에는 콩나물에 키도산을 이용한 재배법이 알려져 있으나 이는 키토산이 살균효과가 있기 때문에 이를 이용하여 콩나물의 신선도를 유지토록 함으로서 종래에 사용되는 식물생장호르몬과 합성항생제 및 비료등을 사용치 아니함으로서 소비자의 건강을 해치게 되는 문제점을 해결하고자 한 것이 있으나 사용되는 물이 신선할 경우에는 키토산의 사용이 아무런 의미가 없게 되는 것이다. 
     다. 발명의 해결방법의 요지. 
     콩나물에는 단백질의 합성에 반듯이 필요한 필수아미노산을 모두 갖추도록 함으로서, 고소한 맛을 향상시켜 콩 특유의 비릿한 향에 의하여 콩나물을 섭취하지 못하는 유아들에게는 섭취할 수 있도록 한 것이다.

Abstract: PURPOSE: Provided is an advanced wastewater treatment method using sulfur granules as media for nitrogen removal in sewage, which is characterized in that autotroph adhered to the surface of sulfur granules oxidizes various sulfides to SO4¬-2, simultaneously transferring NO3¬- to N2 gas without exterior carbon sources. Above chemical reaction is as follow: NO3 + 1.1 S + 0.4 CO2 + 0.76 H2O + 0.08 NH4¬+ --> 0.5 N2 + 1.1 SO4¬-2 + 1.28 H¬+ + 0.08 C5H7O2N. CONSTITUTION: The process comprises an anaerobic tank (30) and nitrification tank (aerobic condition) (50) for phosphate removal and nitrification of ammonia nitrogen; a final sedimentation tank (60) for settling of sludge by gravity force; a sulfur-denitrification tank (150) installed at the rear of the final sedimentation tank (60); a bio-filter (140) installed in the sulfur-denitrification tank (150). Further, a sludge return line (80) is connecting the anaerobic tank with the final sedimentation, another sludge return line (120) connects the sulfur-denitrification tank with the final sedimentation tank.
