Abstract:The Dianshan Lake is an important area for drinking water supply protection and ecological conservation in Shanghai. Over the last ten years, its increasing eutrophication and the resulting algae bloom, had severely threatened the safety of Shanghai’s drinking water supply. To provide a scientific basis for its pollution control and water quality improvement, based on different scenarios of water quality control targets (WQCTs), the Dianshan Lake’s water environmental capacities for COD, TN and TP were calculated. Study results show that: (1) To maintain current water quality conditions, the lake’s environmental capacities for COD, TN and TP were 47213t/a, 8337.7t/a, and 476.3t/a, respectively; (2) If the WQCTs were set as level II, the lake’s environmental capacities for COD, TN and TP are 46325t/a, 1191.1t/a, and 59.5t/a, respectively. (3) If the WQCTs were set as level III, the lake’s environmental capacities for COD, TN and TP are 68547t/a, 2382.2t/a, and 119.1t/a, respectively. (4) If WQCTs were set as level IV, the lake’s environmental capacities are 3573.3t/a were 238.2t/a for TN and TP, respectively.
