Abstract:In order to understand the pollution characteristics of aquacultural wastewater in freshwater ponds in the demonstration zone of green and integrated ecological development in the Changjiang River Delta (Wujiang District, Qingpu District, Jiashan County) and the treatment effect of the wastewater treatment system, the water quality indices were monitored in the of 46 freshwater farms in the core area of the Changjiang River Delta, and the treatment effect of the wastewater in 30 of them were monitored in November—December 2022 (Winter) and June—August 2023 (Summer). Water quality labeling index (WQI) and cluster analysis (CA) were used to analyze all monitoring sites. It was found that the average annual concentrations were (2.80±1.53) mg/L in total nitrogen (TN), (0.49±0.33) mg/L in total phosphorus (TP) and (18.97±17.81) mg/L in permanganate index (CODMn) in the wastewater of freshwater ponds in the core area of the Changjiang River Delta. The rates of conforming wastewater was 58.70% in summer and 82.61% in winter, with the most serious wastewater pollution from Macrobrachium rosenhali (WQI mean 6.8), followed by Micropterus salmoides (WQI mean 6.4), and the least serious from Eriocheir sinensis (WQI mean 4.2). The tailwater purification facilities investigated in this study had good purification effect on aquaculture tailwater, all meeted the discharge standards, with the annual removal rates of (49.02±17.38)% in TN, (34.50±21.15)% in TP and (39.93±23.58)% in CODMn in aquaculture tailwater. The findings provided scientific basis and reference with the targeted configuration of tailwater treatment facilities for main breeding species or varieties in the core area of the Changjiang River Delta, reduced the construction cost and operation and maintenance cost, and improved the purification effect.
