苏州河河道曝气复氧探讨

经过六支流截污、综合调水等苏州河综合整治一期工程项目的实施，苏州河沿岸的污染源大部分已被截留，河水水质大有改善。但是，苏州河北新泾以下河段，由于沿江37座合流泵站雨季排江的冲击负荷，雨天苏州河水体仍有黑臭。向苏州河进行曝气复氧，能在较短的时间内提高水体的溶解氧水平，增强水体的净化功能，对解决突发性的冲击负荷所造成的水质恶化、消除水体黑臭、恢复苏州河水生生态系统，将起到重要的作用。

Approach on Re-aeration of Suzhou Creek

After implementation of rehabilitation projects such as wastewater interception on six Suzhou Creek tributaries and integrated low-flow augmentation of Suzhou Creek, most of the pollution sources along Suzhou Creek and its main tributaries have been intercepted and the water quality of Suzhou Creek has been improved greatly. There are altogether 37 combined pump stations along Suzhou Creek from the Beixinjing to the river mouth. During rain season especially in storm the combined wastewater are drained directly into Suzhou Creek, the creek water becomes black and odorous again. Re-aeration to Suzhou Creek can cope with the consequence of water quality deterioration caused by unexpected shock loading, eliminate the black and odour of the water body and restore the aquatic ecosystem of Suzhou Creek.
