An eco-friendly recirculating and filtering integrated aquaculture system based on salinity tolerant aerobic granular sludge and microalgae

The present invention relates to an eco-friendly circular filtration complex aquaculture system based on salt-resistant aerobic granular sludge and microalgae for the zero-discharge circular use of cultured water in fish farms. More specifically, provided is a system in which a membrane separation tank inoculated with the salt-resistant aerobic granular sludge is operated as a sequencing batch reactor (SBR) to efficiently process organic matter and ammonia nitrogen generated from feed residues and waste products generated during a shrimp and cockle farming process, remaining nitrate nitrogen is consumed by microalgae, and increased microalgae biomass is provided as a food source for cockles. According to the present invention, an environmentally friendly and efficient aquaculture system can be provided. 본 발명은 양식어장의 양식수 무배출 순환 사용을 위한 내염성 호기성 그래뉼 슬러지와 미세조류 기반 친환경 순환여과 복합양식시스템에 관한 것으로, 더욱 상세하게는 내염성 호기성 그래뉼 슬러지가 접종된 막분리조를 연속 회분식 반응조(sequencing bactch reactor, SBR)로 운영하여 새우와 꼬막 양식과정에서 발생하는 사료 찌꺼기 및 노폐물로부터 발생하는 유기물 및 암모니아성 질소를 효율적으로 처리하며, 잔류한 질산성 질소를 미세조류가 섭취하고 증가된 미세조류 바이오매스를 꼬막의 먹이원으로 제공하는 시스템을 제공한다.
