Abstract: A system of cultivating aquatic product and plant contains: a cultivation tank, a blower configured to pump air into the cultivation tank, a first pump, a protein separator, a first ultrafiltration unit, a collection chamber configured to hold bubbled fluid, a second ultrafiltration unit configured to maintain mucus and solid suspension substances in water, a first gathering bucket configured to hold cloudy high-protein concentration fluid, a second gathering bucket, a Nano-filtration unit, a recycle tank configured to hold the recyclable water from the Nano-filtration unit, and a second pump used to pump the recyclable water back to the cultivation tank. The first pump includes a first tube and a second tube. The protein separator includes a hollow cylinder, a bubble generation unit, an outlet pipe, and a bubble pipe. The first ultrafiltration unit includes multiple ultrafiltration films equidistantly. The Nano-filtration unit includes multiple Nano-filtration films.

Abstract: An aquaculture system contains: a cultivation tank, a vortex separator, a drawing pump, multiple bubble separators, multiple filtering units, an aeration unit, and a collection tank. The cultivation tank includes multiple first plates, multiple second plates, an open accommodation chamber, and a conduit tube. The vortex separator includes an inlet and an outlet. The drawing pump is connected beside the vortex separator and the outlet. Each bubble separator includes a cylindrical container and a micro bubble generating unit. Each filtering unit includes a filtration room, multiple filtering membrane sets, at least one water pipe, multiple dish-shaped bags, and multiple vacuum pumps. The aeration unit includes multiple air supply pipes, and the collection tank is employed to receive residual baits and excrements of little fishes or shrimps and particulate matters from the second discharge orifice of each bubble separator and the filtration room.

Abstract: A method of cultivating aquatic product and plant contains steps of: (A) Preparing a cultivation tank with cultivation water; (B) Aerating the cultivation water; (C) Drawing overflow water in a top of the cultivation tank and foul water in a bottom of the cultivation tank into a protein separator and a first ultrafiltration unit; (D) Collecting bubbled fluid from the protein separator and concentrated waste fluid from the first ultrafiltration unit into a collection chamber; (E) Pumping the cultivation wastewater into a second ultrafiltration unit and filtering the cultivation wastewater by using ultrafiltration films of the second ultrafiltration unit; (F) Discharging cloudy high-protein concentration fluid into a first gathering bucket; (G) Pumping filtered fluid filtered by the plurality of ultrafiltration films of the second ultrafiltration unit into a Nano-filtration unit; and (H) Flowing the recyclable water into the cultivation tank from the recycle tank.
