- Abstract:
- The scale of a sewage treatment plant in Shanghai reached 40×104 m3/d after expansion, and the new permanent tail water discharge pipe project discharged all the effluent to the bottom of the Yangtze River outside the new levee. The discharge route of 5.35 km in land area and 1.91 km in water area section was selected by analyzing the topography, hydrology, navigation and environmental impact and other conditions of the nearby Yangtze River estuary. The project consisted of 2 underground pipes with diameter of DN2 400, 2 underwater discharge pipes with diameter of DN2 000 and 1 emergency discharge pipe, which crossed the Yangtze River embankment twice. The pipes in water section were constructed with steel pipe jacking and were equipped with rising pipe and discharge nozzle. The discharge pipe has been built and put into use with good performance, which plays an important role in improving the regional water environment and provides reference for similar projects.
