The application discloses a fresh water circulating aquaculture whole-process water treatment system and method, and belongs to the technical field of circulating aquaculture water treatment. The system comprises a water inlet treatment subsystem, an aquaculture pond subsystem and a tail water treatment subsystem which are sequentially and circularly connected. The water inlet treatment subsystem comprises a water storage tank, a sand filter tank and a filtered water tank which are sequentially connected. The aquaculture pond subsystem comprises a plurality of aquaculture pond circulation combinations, and each aquaculture pond circulation combination comprises an aquaculture pond cluster, a first microfilter, a circulating pump pond, a biological aerated filter, a disinfection pond, a decarbonization device and an oxygenation and temperature adjustment pond which are sequentially and circularly connected. The tail water treatment subsystem comprises a second microfilter, a sulfur autotrophic denitrification pond and an SBR reaction pond cluster which are sequentially connected. The system integrates fresh water circulating water treatment, tail water treatment and source water treatment, can meet the requirements of medium and large fresh water circulating aquaculture plants on aquaculture water quality, can save land occupation and investment, and meets the requirements of green and sustainable development.
