"Mengqing Garden" is rich in popular science and cultural connotation. On the basis of restoration and restoration of historical features, some buildings (brewing building and filling workshop) of the former Shanghai Brewery in the park have become the exhibition center of Shanghai's water environment management, which systematically reflects the evolution, degradation and restoration process of the river ecosystem, focusing on the scientific principles and engineering measures adopted in Suzhou River management, and summarizes the cultural context and coastal construction and development planning of Suzhou River through a large number of precious materials.
The whole park is divided into indoor exhibition area (transformed from excellent historical protection buildings), indoor outdoor exhibition area (including artificial wetland and artificial landscape forest) and riverside landscape belt (connected by nine small scenic spots such as stone steps bamboo dew and Qushui Meng Qing) to meet people's multiple demands for garden leisure. The overall layout adopts the pattern of "one heart, one ring and two axes", with the popular science square as the center, the main loop as the link to connect scenic spots, and the axis avenue integrating landscape and popular science exhibition, retaining the old brewery building in the park, showing the tortuous story of "man and river" here, and integrating science, history and ecology in the "dream garden", which not only shows the atmosphere of western gardens, but also shows China.
Meng qingguan
Suzhou River Exhibition Center was transformed from the original brewery canning workshop, with an exhibition area of 3,200 square meters.
The exhibition hall is divided into three layers, mainly through physical objects, models, pictures, movies, multimedia interaction, feelings, operation demonstrations and explanations. Introduce and show the historical changes, achievements in water control and the beautiful integration of Suzhou River.
First floor:
The Story of Suzhou Creek —— Introduce the geographical location of Suzhou Creek and the water conservancy system in Shanghai.
Dozens of exhibition systems show the vicissitudes of Suzhou River. As the mother river of Shanghai, Suzhou River draws a curve from agriculture, fishery to industry and commerce, from irrigation and fishing to shipping and sewage discharge, which objectively and truly reflects the relationship between man and nature. Today, the history of nature actually contradicts the history of human existence, which is a fact that we can never accept.
Shanghai is located on the coast of the East China Sea, but it is a city short of water. The polluted Suzhou River once hindered the better development of Shanghai. Man-made waste and destruction of water resources are the direct causes of water shortage. Meng Qing Pavilion strengthens the significance of water environmental protection to human survival, and refines the clearness and remoteness of Suzhou River. The water system model highlights the status and role of Suzhou River in Shanghai, and introduces Suzhou River as a successful example of polluted river treatment.
Second floor:
Changes of Suzhou Creek —— Brief Introduction of Suzhou Creek Pollution in Ancient and Modern Times and Its Harm to Human Beings
The real super-long multi-hot area image system makes the ecology of Suzhou River in ancient times, the causes and treatment methods of Suzhou River's black odor leap on the touch screen, and a large number of graphic materials show the close relationship between human behavior and the natural environment.
The derivatives of human development-river culture and bridge culture-will inevitably be depressed with the deterioration of water environment and prosper with the improvement of water environment. Suzhou River is also a multi-bridge river, and every bridge lying in the north and south is a part of Suzhou River. The simulation model of Shanghai's famous Waibaidu Bridge in the museum brings people back to that era.
Multimedia cinema, large-scale mirror interactive broadcasting, super-long multi-hot zone imaging system, three-dimensional demonstration and yacht simulation tour, etc. , so that popular science, visualization and entertainment can be more fully played.
The third floor:
Regulation of Suzhou Creek-Introduce the regulation process and present situation of Suzhou Creek.
A large number of pictures and materials recorded the three large-scale regulation processes of Suzhou Creek. After the first and second phase of comprehensive environmental improvement projects, Suzhou River has basically bid farewell to black odor. Recently, several kinds of small fish, such as wheat spike fish, betta fish and pomfret fish, have appeared in Hanoi, Suzhou. Egrets often gather around them, which shows that the ecology of Suzhou River is recovering.
The data and photos of the combined sewage, the first-stage treatment and the second and third-stage treatment will present the historical process of the treatment in front of you. 12 square meter large mirror can be commanded by the audience's fingers; The model of estuary sluice and rainwater storage tank vividly shows the whole picture of biological purification and ecological reconstruction project of landscape water body; The story of Suzhou River, a large-scale four-act multimedia theater, reviews the changing history of Suzhou River, shows the functional planning of Suzhou River in the future, and arouses people's awareness of protecting the mother river, which is the treasure of the town hall.
Meng Qing Museum recorded the Suzhou River yesterday, today and tomorrow.
Here, people can not only understand the changes of Suzhou Creek and Shanghai, but also see the close relationship between water veins and historical context. By visiting the learning resources in the museum, we can understand the basic methods of water treatment, let people know the crisis of water resources, see the preciousness of water resources, and understand the close relationship between water resources and themselves. We should start from ourselves and do nothing harmful to water resources, so as to make the water around us clearer and the sky bluer.
1, Mengqingyuan constructed wetland
Meng Qing Suzhou River Landscape Water Purification System is a national 863 program demonstration project, covering 12 patent achievements. The biological purification system of Mengqingyuan landscape water body is a surface flow constructed wetland treatment system, also known as free water and constructed wetland, which is similar to natural wetland. It is like a natural filter purifier. After the water from Suzhou Creek entered Meng Qing Garden from here, it decomposed and removed many pollutants, and the water quality was purified and improved. The whole system consists of five parts: folded water flow, reed wetland, oxygen barrier, middle lake and lower lake (submerged plants) and clean energy aeration reoxygenation system.
After treatment, the biological purification system restored the original appearance of water, and let Mengqingyuan solve the large-scale green water demand by its own water treatment system. After purification, the water quality improved 1-2.
2. Mengqingyuan rainwater storage pond
Urban domestic sewage and industrial wastewater are collected through municipal pipelines, and discharged after being treated by sewage treatment plants, and will not directly flow into rivers. When the rainfall exceeds the drainage standard, start the sewage pump of the pumping station to transport the combined sewage to the sewage treatment plant, and the initial rainwater collected by the pipeline will be intercepted and enter the storage tank. When the amount of rainwater in the initial stage of river closure is less than the volume of the storage tank, it is not necessary to start the rainwater pump to drain the Suzhou River, which will not cause pollution to the Suzhou River. When the amount of rainwater at the initial stage of river closure is greater than the volume of the storage tank, the rainwater pump will be turned on to drain the Suzhou River when the storage tank is full, so as to reduce the pollution to the Suzhou River.
