Embodiment Construction
[0026] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0027] Taking Suzhou Port XX Port Area X Phase Project as an example, the main way of rainwater drainage is rainwater pipes. The clean rainwater in the storage yard is collected through open ditches and hidden pipes and then discharged into the rainwater pump room. It is discharged through gravity flow at low tide in the Yangtze River, and discharged through submersible axial flow pumps at high tide. Domestic sewage is collected through hidden pipes and lifted by sewage lift pumps. Then connect to the municipal sewage pipe network.
