Tianjin plans to invest 25.4 billion yuan to implement a new round of ecological city construction action since this year. According to the “2011-2013 Tianjin Eco-city Construction Action Plan†(hereinafter referred to as the “Planâ€) issued by Tianjin, Tianjin will implement energy conservation and pollution reduction, pollution reduction, water environment management, construction of ecological network barriers, solid waste and noise control. Seven projects, such as rural environmental protection and circular economy, make Tianjin more blue, clearer, and greener, and promote the construction of a unique international, modern and livable city.
According to the "plan", by 2013, the black odorous water body will be basically eliminated, and the water quality compliance rate of centralized drinking water sources will be 100%. Accelerate the development of unconventional water, the recycled water reuse rate reached 20%; the desalination scale reached 400,000 tons / day. Gradually increase the proportion of clean energy and outsourced electricity such as natural gas; the newly added urban resident population is controlled within 3 million. The temporary green space is gradually transformed into permanent green space. The per capita public green area of ​​the town reaches more than 9 square meters, and the forest coverage rate reaches 22%. Delineate ecological safety control lines to prevent ecological damage and maintain urban ecological security. Xiqing District took the lead in building a national ecological zone, and the downtown area and Binhai New Area met the national ecological city construction index requirements.
Achieve a uniform and rational layout of green space
You can have green space when you go out 500 meters.
According to the “2011-2013 Tianjin Eco-city Construction Action Plan†(hereinafter referred to as the “Planâ€), Tianjin will newly construct 3 green spaces or small forests in the central city every year to play a role in the regulation of urban climate by wedge-shaped green space and alleviate the urban heat island effect. At the same time, to meet the needs of the public leisure and entertainment.
According to the "Plan", Tianjin will realize the 500-meter service radius requirement for uniform and reasonable layout of public green space. There are more than 3 park green spaces or small forests in the downtown area. Construction of more than one park green space or other green areas in each district of the four districts around the city; construction of four forest plots of more than 1 square kilometer around the outer ring road. The Binhai New Area will build more than 3 park green spaces or other green spaces every year. In the three years, it will build 2 to 4 large-scale forest land of not less than 3 square kilometers to alleviate ecological losses and improve the livability level.
Relying on the western wind-proof and sand-fixing belt, the Jin-Ji Expressway, the Tangjin Expressway and the coastal coastal zone, a shelterbelt and an ecological corridor combining Joe, irrigation and grass will be built. Relying on the important ecological functional areas such as the northern mountainous area, the Dahuangpu-Qilihai, Tuanbo-Beidagang, etc., the forest land and wetland protection and restoration areas are delineated.
In order to protect and repair ecological wetlands such as Qilihai, Dahuangbao, Tuanbo and Beidagang, Tianjin will dredge the water supply channels of wetlands within three years, increase the ecological water supply of wetlands, and maintain the ecological functions of wetland resources. Dredging the Diandi ditches in the East and West Qilihai to communicate the wetland water system and ensure the storage and transportation of the wetland ecological water in the core area of ​​the Qilihai Sea. The use of yellow water and urban reclaimed water to supplement the ecological water use of the wetland protected area.
Strengthening solid waste and noise management
Building 60 quiet residential quarters
In the new round of eco-city construction action plan, strengthening solid waste and noise control is one of the seven major projects to be implemented. Tianjin will continue to promote the construction of quiet residential quarters and build 60 quiet residential quarters.
It is reported that Tianjin will formulate and improve the district and county noise evaluation system with the key to the compliance rate of noise functional zones, and improve the environmental noise management mechanism of districts and counties.
Strict construction site noise management, application of new technologies, new processes, new equipment, replacing the backward construction methods, eliminating the noise-polluting foundation pit ring beam using air compressor demolition process. Strengthen the control of urban road noise pollution, and strictly enforce the regulations for banned horns in the central city.
In terms of improving the level of domestic garbage treatment, Tianjin will implement a diversified disposal method of domestic garbage based on incineration to optimize and improve the layout of domestic garbage treatment facilities. Accelerate the construction of a number of domestic garbage treatment facilities such as Hangu, Dagang Domestic Waste Incineration Power Plant, and build a number of garbage transfer stations. Gradually establish household garbage disposal systems for household classification, village reduction, town transportation, and district and county treatment. Realize the harmless treatment of sludge in the whole city sewage treatment plant, and build Dagang and Handan sludge drying plants.
Stamping parts are metal or plastic components that are produced by stamping or pressing a sheet of material with a die. This process involves the use of a stamping press, which applies pressure to the material to shape it into the desired form. Stamping parts are used in a wide range of industries, including automotive, aerospace, construction, and electronics. Some common examples of stamping parts include brackets, clips, connectors, hinges, and terminals. The advantages of stamping parts include high production efficiency, low cost, and the ability to produce complex shapes and designs.
