摘要:
为定量预测扬州城区2个大型污水处理厂排污口(总规模46万m3/d)尾水排放对水环境的影响,应用MIKE11和MIKE21水动力水质模型,同时结合城区河网水动力水质模型,选取化学需氧量(CODcr)和氨氮为评价指标,分别对尾水正常排放和事故排污进行数值模拟。结果表明:正常排放时,对长江和大运河均无明显影响; 当2个污水厂均发生事故排污时,大运河整体受到严重污染,长江岸边近2.4km水域会受到影响,污染物浓度及影响范围均增大。预测结果量化了污水厂事故排污的影响范围和影响强度,为排污口优化布局和管理提供科学依据。
Abstract:
In order to quantitatively predict the influence of tail water discharge on the water environment of the two large sewage treatment plants in the urban area of Yangzhou(total processing scale of 460000m3/d), applying the MIKE11 and MIKE21 hydrodynamic water quality models, combined with the urban river network hydrodynamic water quality model, the chemical oxygen demand(CODcr)and ammonia nitrogen were selected as the evaluation indicators to simulate the normal tail water discharge and accident discharge.The simulation result showed there was no significant effect under the condition of normal discharge.However, when the two sewage treatment plants both had accidents, the Grand Canal as a whole was seriously polluted, the nearly 2.4km water area along the Yangtze River would be affected, and the pollutant concentration and influence range would be increased.The predicted results quantified the influence scope and intensity of the accident discharge of sewage treatment plant, and provided scientific basis for the optimized layout and management of sewage outlet.
