Abstract：To explore an eco-friendly approach for tail water treatment，this study investigates the construction model and operational strategies for a "zero discharge" system for aquaculture tail water based on the mechanism of bacterial一algal symbiosis. By analyzing the metabolic complementary mechanisms between bacterial communities and microalgae，a multi一module synergistic process centered around a photoreactor is proposed to establish a closed-loop system for the synergistic conversion of carbon，nitrogen and phosphorus. Using the aquaculture park in Sihong，Jiangsu Province as a case study，system deployment and operational efficiency were evaluated. The results demonstrate that the system achieves effective pollution reduction and synergistic resource recovery，confirming its feasibility and promotion for broader application in aquaculture tail water treatment.
