Although such container culture systems can reduce the discharge of culture wastewater and wastes, the water environment burden caused by the large culture density is large, if a high-power water circulation system is started for a long time, although the water quality can be effectively purified, water flow activity can be generated in the culture unit and fish schools can be gathered to cause that the water quality of partial areas is difficult to circulate and bacteria are bred, so that the growth of aquatic products is influenced, and the water quality of the high-density fish school culture is difficult to purify by the low-power water circulation system, particularly, the water pollution caused by collective excretion needs long-time water circulation to be purified. Therefore, there is a need to develop a modular ecological aquaculture water treatment system
