The bulk cargo ports in north China face many difficulties，such as the lack of freshwater resources，waterlogging in the storage yard during heavy rain seasons，dust pollution，and noise pollution. Considering this，this study focuses on green upgrading and transformation of bulk cargo ports. Guided by the environmental problems confronted by bulk cargo ports，this study summarizes the direction of green upgrading and transformation of bulk cargo ports on the basis of the green design concept. By referring to an engineering case，this paper proposes a specific scheme in this regard. Specifically，a new ecological reservoir can be constructed to establish the port water circulation system，which can realize the full collection，total processing，and full reuse of rainwater and sewage in the port area under the intensity of rainstorms once in two years. The whole-process pollution control can effectively reduce the dust concentration and noise value in the port area.
