| 中文摘要: |
| 通过开展城镇污水处理模拟实验，与WATER9模拟结果比对和误差分析，使用优化后的WATER9模型模拟计算扬州汤汪污水处理厂一期工程的VOCs排放量，并分析各参数对VOCs排放量的影响。结果表明：WATER9模型满足城市污水处理厂污水处理过程中VOCs排放量的模拟要求，优化后的模拟值与实测值之间的相对偏差小于8%。实验结果表明，加盖处理能大幅度减少污水处理过程中VOCs的排放，汤汪一期加盖后VOCs排放量下降了88.8%，废水温度和表面风速也是影响VOCs排放量的重要因素。 |
| 英文摘要: |
| Through the simulation experiment of urban sewage treatment, comparison with WATER9 simulation results and error analysis, the optimized WATER9 model was used to simulate and calculate the VOCs emissions from Yangzhou Tangwang Sewage treatment plant phase I project, and the influence of each parameter on VOCs emissions was analyzed. The results showed that WATER9 model met the simulation requirements of VOCs emissions in the sewage treatment process of urban sewage treatment plant, and the relative deviation between optimized simulation value and measured value was less than 8%. The experimental results showed that capping treatment greatly reduced VOCs emissions by 88.8% in sewage treatment of Tangwang phase I project. Wastewater temperature and surface wind speed were also important factors affecting VOCs emissions. |
