| 摘要: |
| 在对青岛浮山湾帆船基地海域水质现状分析评价的基础上, 利用二维平流-扩散模型, 选取化学需氧量(Chemical oxygen demand, 简称COD)作为水质指标因子, 按麦岛污水处理厂改造扩建前、改造扩建后正常运行及改造扩建后事故运行3 种情况, 对污水排海给帆船基地海域水质带来的影响进行了预测和分析。由3 种情况预测结果可以看出: 1)麦岛污水处理厂改造扩建后, 大大改善浮山湾帆船基地周围海域的水质情况; 2)麦岛污水处理厂改造扩建后, 正常运行情况下入海COD 对帆船基地海域水质的影响不大, 海水中COD 浓度未出现超一类海域水质要求的情况; 在事故运行情况下入海COD 在排污口附近有超一类海域水质的现象, 面积最大为2 674 m2, 未出现超二类以上海域。 |

| Abstract: |
| Based on the assessment of current water quality of Qingdao sailing base, using a two-dimensional diffusion model and Chemical oxygen demand (COD) as the index factor of sea water quality, we analyzed and predicted the impact of discharge on the water quality of Sailing Game area in three situations. After the reconstruction and expansion of Maidao sewage treatment plant, the water quality of Sailing Game area in Fushan Bay had been greatly improved, and the discharge COD had little effect on the water quality of Sailing Game area under normal operating conditions, where the COD concentration was within scope of National Grade I. Under the accident conditions, the COD concentration at the outlet exceeded the standard of National Grade I, the maximum area is 2674m2, but there was no area exceeding the standard of National Grade II. |
