The invention provides an indoor circulating water high-density cultivation process for prawns, which includes a cultivation pond, a spin microfilter, an air screen type protein separator, a positive and negative biological processor, a bag collector, a sediment pond, and a bait fish pond Or tilapia culture ponds, sedimentation ponds, and ecological return ponds, the spin microfilter is connected to the culture pond through a water pump, and the bag collector is used to collect the solid waste of the spin microfilter, which is treated by the spin microfilter The final clean water flows to the air screen protein separator, and then flows to the forward and reverse biological processor, the forward and reverse biological processor is connected to the sedimentation tank, the spin microfiltration machine is connected to the sedimentation tank, the sedimentation tank is connected to the ecological return tank, and the bag type collection Both the tank and the sediment tank are connected to the bait fish pond or the tilapia culture pond. The invention has no waste of water source and waste of residues, so as to achieve maximum utilization, reduce environmental pollution, and reduce energy consumption.
