The invention relates to the technical field of aquaculture wastewater treatment, and discloses an integrated vertical tank aquaculture water treatment process which comprises the following steps: S2, carrying out solid-liquid separation treatment on wastewater in S1, S3, pumping the wastewater treated in S2 into an anaerobic tank, S4, enabling the wastewater in S3 to annularly flow to a water outlet under the assistance of a submersible stirrer in an anoxic zone, and S4, carrying out anaerobic treatment on the wastewater in S3, s5, enabling the wastewater in S4 to enter an aerobic tank, and providing oxygen by a blast system for nitration reaction, S6, controlling the reflux quantity of a mixed solution for the wastewater in S5 by adjusting the opening and closing size of a mixed solution reflux gate valve, enabling the mixed solution of the wastewater in S7 and S6 in the aerobic zone to pass through a settling zone, enabling supernate to flow to a next treatment process section from an effluent weir at the
