In the process of economic development and urban construction, Dalian always pays attention to transforming the mode of economic growth, optimizing the industrial structure, continuously enhancing the capacity for independent innovation, vigorously developing the circular economy, and striving to complete the energy-saving and pollution-reducing pollution reduction targets. At present, Dalian has initially embarked on a virtuous cycle of environmental protection and economic and social development.
In the first half of this year, Dalian's economic development rate reached a record high, with regional GDP increasing by 17%, local fiscal revenue increasing by 37.8%, and the comprehensive energy consumption rate of 10,000 yuan being reduced by 4.2%. The decline was 5.1%, the energy conservation contribution rate ranked first in the province, and the total discharge of major pollutants decreased by 2.5%. Last year, the energy consumption per 10,000 yuan of GDP in Dalian fell by 4.4%, and the total discharge of major pollutants decreased by 2.5%, which was lower than the national control index. Also in 2006, Dalian passed the inspection and acceptance of the “National Environmental Protection Model Cityâ€. Energy saving and emission reduction, Dalian is the leader in the province. Dalian has provided many useful inspirations when some cities and industries are struggling to save energy and reduce emissions.
Revelation 1: Structural adjustment and subversion
Dalian has always been dominated by heavy chemical industry, which is not only a city with large energy consumption, but also a city with severe resources. In 2006, the city's comprehensive energy consumption totaled 24.6 million tons of standard coal, and the total social power consumption was 18.4 billion kWh, ranking first among cities in the Northeast. In order to effectively achieve energy conservation and consumption reduction, we must first start from changing the industrial structure.
The heavy chemical industry in Dalian is mainly concentrated in industrial areas such as Ganjingzi, and the industrial layout is unreasonable, resulting in structural pollution. In recent years, Dalian has implemented relocation and transformation of some heavy chemical industrial enterprises. Those enterprises with large investment and serious pollution have been “selled†on the spot and have since withdrawn from the historical stage. A group of small thermal power units represented by two small fuel-fired units of the original Dalian Power Plant are “end to sleepâ€, while the energy-saving, environmentally-friendly and efficient large-scale coastal power station – Zhuanghe Power Plant’s 600,000 kW supercritical Unit 1 officially Putting into commercial operation marks that the "thermal power revolution" with a large pressure has achieved a decisive victory in Dalian.
In recent years, Dalian City has finally subverted the status of the “big boss†of heavy chemical industry through a big move. At present, the modern equipment manufacturing industry, including the shipbuilding industry, has become a leading industry in Dalian, followed by the electronic information and software industry.
In the industrial parks of Dayaowan and Dalian Bay, the development of modern equipment manufacturing industry is in full swing. On the basis of the rapid development in previous years, in the first half of this year, the investment in equipment manufacturing in these two districts increased by 60%. The shipbuilding industry belt on the Bohai Sea coastline is booming, and the investment growth rate is as high as 175%. At the same time, a large number of strategic industries, such as high-end CNC machine tools, wind power equipment, large-scale crankshafts for ships, and large-scale marine projects, have continuously made new breakthroughs in the intensive implementation. Industries such as automobiles, machine tools, and heavy equipment began to show cluster effects.
There is no environmental pollution, only less energy consumption. In 2006, 620 software and service outsourcing companies in Dalian created a production value of 14.5 billion yuan, and an IC hardware industry group is gradually taking shape in Dalian. Today, Dalian has clearly proposed to build China's largest, highest level, and most technologically advanced integrated circuit industry base.
Revelation 2: Energy substitution blooms wonderfully
In order to compose a concerto of resources, environment and development, the development of new energy is an inevitable road. The breakthrough point of Dalian's energy conservation and consumption reduction work is to develop and utilize new energy.
According to statistics, in the summer season, the electricity consumption of air conditioners in Dalian accounts for more than 1/4 of the total electricity consumption, while the “seawater air conditioner†green energy technology can effectively reduce the power load. In the vicinity of Xinghai Square, an Xinghaiwan seawater heat pump project covering an area of ​​10,000 square meters and designed to install 12 units with a heating and cooling area of ​​2 million square meters is under construction. The endless seawater will provide warm winter for Dalian people. Send cool. At the same time, Dalian Xiaopingdao New District large-scale seawater source heat pump project was also started on May 28 this year, with a total heating and cooling area of ​​1.37 million square meters, which can be used for seawater heating this winter. Compared with the traditional method, “seawater air conditioning†can save 40% energy. According to the scale of the first phase project of 500,000 square meters, it is estimated that 63,000 tons of standard coal will be saved every year.
Desalination has now become a mature technology in power plants such as Huaneng Dalian Power Plant and Guodian Zhuanghe Power Plant, and is fully used in power plant water circulation systems. To the sea to water, at present, Dalian has built six large-scale desalination plants. In the first half of this year, the water consumption per unit of GDP in Dalian fell by 11.8%, and the desalination technology played a role in fueling the situation.
Wind power is the leader of new energy, and Dalian is the center of research and development and manufacturing of wind power equipment in the country. Two years ago, Dalian Heavy Industry Group Co., Ltd. identified high-power wind power equipment as the main direction of adjusting product structure. Now, it has taken the lead in realizing the localization and specialization of high-power wind power equipment in the same industry in China. produce. At the same time, the scale of wind power generation in Dalian has also grown rapidly. Dalian Power Generation Company started construction of a wind farm with a total capacity of 1 million kilowatts in the Wafangdian area. Now, the wind power generation in Dalian has initially qualified for the fall of the firepower level.
The number of sunshine hours in Dalian is higher than the national average. Dalian makes full use of this unique resource. On the one hand, through the integrated design and construction of building engineering and solar water heaters, on the other hand, through technological innovation, it promotes the core raw materials in solar cells, that is, the “technical silicon†with the highest technical content. The research and development of related issues such as production and high conversion rate of concentrating photovoltaic cells have accelerated the transformation of fuel cell technology into application. It has also been at the forefront of the country and even the world, laying a solid foundation for the development of solar energy industry. It also achieved a zero breakthrough in Dalian. The largest domestic waste incineration treatment project in China is currently entering the construction phase in Dalian. The total investment of this project is 750 million yuan. It adopts internationally advanced circulating fluidized bed incineration technology to calculate 1,500 tons of waste per day, and waste heat from waste incineration. Vapor is used for power generation, with an annual generating capacity of 223 million kWh. It is expected that the entire project will be put into operation in 2008, when Dalian will bloom a new energy.
