In the past few days, the “poisonous land†incident in Changzhou Foreign Language School has continued to ferment, making land pollution prevention and control once again the focus of public opinion. Some countries with earlier industrial processes have also faced the problem of pollution control and restoration of abandoned industrial land in cities. Generally speaking, many heavily polluted land has not been transformed into commercial and residential land, but a large-scale forest park has been built. The soil can be naturally restored through extensive planting of vegetation and establishment of ecosystems. Practice has shown that the renewal and transformation of these industrial wasteland can not only continue the unique historical memory of the base, but also successfully improve the urban environment. Starting from the typical case of abandoned industrial land management, it provides reference for the restoration and transformation of polluted land in China. Eden Project in the UK: Building a greenhouse garden on a clay pit The children play outside the Eden Greenhouse Botanical Garden. Cornwall, in the south of England, was famous for producing clay minerals in porcelain. A 50-meter deep, 30-story football-sized waste mine near St Austell has been successfully converted into the Eden Project, the world's largest greenhouse botanical garden. The project cost £74 million and accommodates more than 1 million plants and nearly 5,000 plants from all over the world. It presents different natural landscapes under different climatic conditions and is called “the eighth wonder of the world†by many people. The Eden Project is connected by several dome-shaped buildings. The truss frame is a hexagonal shape made of steel pipes. It is covered with a transparent cover made of light materials and has good heat preservation. Inside the building are two huge greenhouse botanical gardens, one recreating the natural environment of the tropical rainforest, the other showing a warm temperate plant landscape, and the outdoor area connecting the two greenhouses is an open-air plant area. The idea of ​​the Eden Project originated from a storm that hit Cornwall in 1990. Many of the protected cultural heritage courtyards were severely damaged, and many plants collected and cultivated from all over the world were also facing extinction. To this end, the experts have chosen this site that has been polluted and destroyed by industry to rebuild an “isolated†natural ecological zone through environmental regeneration. The biggest problem facing the initial stage of the project is the soil. The main component of the abandoned pit is clay, which lacks the nutrients needed to support the growth of a large number of plants. To this end, the staff mixed the clay waste in the soil with organic waste such as kitchen waste and waste wood. The compost decomposes the waste material, produces nutrient-rich fertilizer, and combines it with the available soil to form a fertile fertilizer. soil. This fertile soil takes hundreds of years to form under normal geological processes. In this way, the staff produced about 85,000 tons of soil and planted terraced plant belts according to the old mine terrain. North Duisburg Park, Germany: a leisure park with steel-framed pipes The concrete walls in the North Duisburg Park became a paradise for climbers. Gray iron plate and rusty steel frame is the impression of abandoned steel mills, and Duisburg, Germany, North Park, but through innovative ideas and brownfield management, to break down the traditional concept. The park was formerly the Medrisi smelter in the north of Duisburg. It was located in the Ruhr area of ​​the German heavy industry production base. It was built in 1902. In the mid-1980s, the citizens organized a protest against pollution and smelted the blast furnace to stop production. In 1991, the government began to renovate its plans to preserve the original appearance of the steel plant to the extent that it correctly recognized and commemorated the pollution caused by the industrial era, rather than completely rejecting or forgetting. The park retains contaminated soil, uses phytoremediation techniques, uses green plants to transfer, contain or transform pollutants in the soil, making it environmentally friendly, and uses a bunker to isolate highly toxic soil cover. At the same time, new uses for existing buildings in abandoned steel plants have been developed, reducing the need for new materials. For example, concrete bunker into a private garden, the pool of waste oil into a diving club's training ground, concrete facades iron ore yard into a rock-climbing wall, a number of warehouses and factories have been transformed into disco and concert hall . Even the fine art of symphony began to play here, using these giant steel smelting furnaces as background. From the outside, the exterior of the park is still a large steel structure elevated, pipes and chimneys, but the interior has built a variety of entertainment facilities, transforming into a public park integrating leisure, entertainment and culture. The steel workshop in the core area has become an open market. Standing in the park overlooking the entire Ruhr industrial area, the famous Emscher River and the Polaris Park are connected, and the former was once the most polluted main sewage river in the Ruhr area. After being managed, it has become a river for tourists to go boating. Oil company BP Australia Heritage Park: Enjoy the harbor side waste depot Visitors enjoy the sea view from the BP Oil Company Heritage Park viewing platform. Australia has very strict governance standards for the restoration of contaminated land. Located on the Weavertown Peninsula in Sydney, it is home to the former BP Petroleum Australia subsidiary. The site was used as an oil storage and transportation station for more than 60 years. It once occupied the office area and 31 oil storage tanks, and the land was inevitably polluted. Like many developed countries, Australia has gradually moved heavily polluting factories away from urban centers and residential areas. The vacant land left by the relocation will be rigorously evaluated by the UNEP, and the developer will submit the application for modification, and the approval and transfer of the contaminated land will be allowed to be converted into non-industrial land. In 1997, the New South Wales government rejected the proposal to sell and develop industrial sites in the Weston area and decided to convert them into parks. As a result, the BP oil company's contaminated land has been transformed into an industrial park of modern style - BP Petroleum Company Heritage Park. In March 2005, the 2.5-hectare site park was officially opened to the public for leisure and entertainment for nearby residents. Strolling through the park, you can see continuous open spaces and large wetlands, as well as spectacular viewing platforms suspended from high semi-circular sandstone suspended surfaces, where huge oil storage tanks once stood. After the renovation design, the use of concrete and metal staircase connects the various spaces, visitors can not only enjoy the historical monuments and geological development of the industry, but also an overview of the urban scenery along the Sydney harbor, including the famous Sydney Opera House. Many of the polluted soil in the park site has not been dug away, but is reused in combination with organic matter and slowly purified by natural laws. At the same time, the remodelers collected a large number of plant stocks from the nearby Gemtou Nature Reserve, which were used as green seedlings after breeding. American Falls River Park: Landfill Changing Animal Habitat The natural scenery of the River Falls Park. The US Rivers River Park is one of the most concerned public works in the world. In 1948, the Fres River, which covers an area of ​​about 9 square kilometers, was opened as a landfill. For more than 50 years, it has been the main solid waste landfill in New York and the largest landfill in the world. . In 2001, New York City began planning this landfill. It plans to use 30 years to transform it into a social public landscape park integrating recreation, culture and education, and as the largest urban park in New York City. At present, the ecological park has begun to appear, and some of the round-the-island tour routes have been opened to a small extent. The park has vast tidal wetlands and streams, more than 64.4 km of trails, as well as entertainment, culture, education, sports and other facilities, as well as a variety of wildlife, birds and habitats. Long-term landfills have caused great damage to the soil, so the biggest problem facing the renovation project is soil remediation and treatment. Topsoil is very expensive in New York, and it is not cost-effective to re-cover the entire landfill surface with high-quality soil. The soil used to cover the waste is very poor and needs to be effectively managed to prevent soil erosion. Therefore, during the renovation, the design team used the strip farming method to transform the existing soil. Specifically, it includes three carefully selected crops per year, which are then broken into soil by a rotary tiller as a green fertilizer. Although the process of this type of governance is relatively long, it is undoubtedly cheaper, and the strip farming method is more effective for land improvement than the introduction of new soil. Not only that, but the reconstruction project also uses the biogas that is separated from the domestic waste below 5 meters to provide gas and heating energy for the public. Downsville Park, Canada: Reconstruction of the former Air Force Base Cultural Campus Citizens participate in large-scale events at Downsville Park. When Swell Park is a park directly under the federal government of Canada, it is located in the northwest of Toronto. The park was formerly known as Haveli Airport and later became the Airsville Air Force Base. In the 1990s, the Canadian government announced the withdrawal of the air base and decided to build it into Canada's first national-level city park. In 1996, the site began to open to the public, including vast grasslands, remnants of the former air force base, trees, and some abandoned buildings. The park site also includes a section of industrial and military buildings with a huge hangar and storage room that will be remodeled for cultural and recreational use. Since the park site has experienced agricultural, industrial, military and other aspects, the natural system has been seriously degraded and needs to be restored and transformed. Therefore, the park reconstruction is divided into three stages: the first stage is to carry out soil renewal and remediation to replant various plants and restore natural ecology. The second stage is to build a park road circulation system to guide tourists along the river bank through the pedestrian bridge on the forest, grassland and wetlands. At the same time, transform the original industrial buildings and military buildings, making it a "cultural campus" for youth education. The third stage is to deepen the stage of improvement. When the goal of Swell Park is to establish a sustainable park that integrates social, economic and environmental development, it is also a valuable educational innovation base for young people and children to meet the dual needs of society and nature. It is one of the world's largest parks. Dish Dryer,Dryer Stainless Rack,Dish Racks Stainless Steel,Kitchen Dish Racks Leeyo Pilot Electric Technology Co., Ltd , https://www.nbleeyo-pilot.com
