Zusammenfassung:The present invention provides a method for growing fish and vegetables using a natural ecosystem cycle farming, by which fish and vegetables can be grown while environmental pollutants and harmful substances are not discharged due to a continuous circulation method by the natural ecosystem. The method of the present invention comprises: a first step of preparing an aquafarm to which vegetable and animal feeds can be supplied according to the kind and size of fish, and transferring, to an activated sludge tank, excrement contaminated water including ammonia nitrogen generated during a step of growing fish in the aquafarm; a second step of changing hazardous ammonia nitrogen to harmless nitrate nitrogen by an activated sludge method including bubbling while contaminated water flowing into the activated sludge tank comes into contact with a photocatalyst and a microbial carrier, and supplying, to a vegetable growing place, activated sludge treatment water for breeding microorganisms beneficial for vegetable crops; a third step of providing nutritional components to growing vegetables by water transferred to the vegetable growing place, and transferring residual water to a water storage tank; and a fourth step of analyzing water introduced to the water storage tank, and performing recycling to an activated sewage tank in the case of water quality inappropriate to be supplied to the aquafarm, or introducing the water to the aquafarm if the water has an appropriate water quality standard. According to the technology related to a circulation system application method, fish can be grown efficiently, and vegetable crops can be simultaneously obtained. 본 발명은 자연생태계에 의한 연속적 순환 방법에 의해 환경오염 물질 및 유해물질을 배출하지 않으면서 어류 및 채소를 키울 수 있는 자연생태계 순환 농법을 이용한 어류 및 채소의 생육방법을 제공하기 위한 기술분야의 발명이다. 본원은 어류의 종류와 크기에 따라 식물성 및 동물성 먹이가 공급될 수 있는 양어장이 마련되고 양어장 내부의 물고기가 생육하는 과정 중 발생되는 암모니아성 질소가 포함된 배설물 오염수가 활성오니조로 이송되는 제1단계와 활성오니조로 유입된 오염수가 광촉매, 미생물 담체와 접촉하면서 버블링(Bubbling)이 포함된 활성오니법에 의해 유해성 암모니아성 질소가 무해성 질산성 질소로 변화됨과 동시에 채소작물에 유익한 미생물을 번식시키는 활성오니법 처리수가 채소재배지로 공급되는 제2단계와 채소재배지로 이송된 물이 재배채소에 영양성분을 제공하고 잔량물을 물 저장조로 이송되는 제3단계와 물 저장조로 유입된 물을 분석하여 양어장으로 공급되기 부적합한 수질인 경우 활성오니조로 리싸이클(recycle)시키고 수질기준에 적합한 경우 양어장으로 유입되도록 적용되는 제4단계 공정을 포함하여 이루어져서 효율적인 어류사육과 채소작물 수확을 동시 얻을 수 있는 순환시스템 적용방법 관련 기술이다.
