In the past two years, the phenomenon of relatively serious air pollution in cities such as Beijing has caused great concern. According to research statistics, these pollutants mainly come from artificial industrial exhaust emissions, automobile exhaust, construction dust.
Recently, the reporter interviewed Guo Yunchong, member of the National Committee of the Chinese People's Political Consultative Conference and former deputy director of the Ministry of Housing and Urban-Rural Development. He believes that under the current situation, it is necessary to further promote energy conservation and emission reduction in an effort to improve the atmospheric environment.
As an expert in urban construction engineering, Guo Yunchong is most familiar with the current problems in urban construction.
"Some people describe the construction of China's cities as twelve words: 'Building fast, breaking fast; breaking fast and building fast'. Because urban planning is lack of science, operability, forward-looking, serious, and authoritative, The situation of the change of the dynasty often occurs." Guo Yunchong worried about this. "In addition, the coordination and coordination between the various professions in various industries is poor, such as water, sewage, gas, electricity, and weak electricity. The three telecommunications companies are also doing their own work, resulting in a lot of redundant construction."
According to China's standards and regulations, the design life of general building construction is 50 years, and the service life of important building design is 100 years. "But the actual service life of urban buildings in China is far from this standard."
"If a building is not demolished for 100 years, it will only cause pollution of one unit in the past 100 years; if it is demolished four times in 100 years, it will consume five units of energy and raw materials, resulting in pollution of five units." Guo Yunchong believes that "this situation must be changed."
In addition, Guo Yunchong also found that the current policy orientation of energy conservation and emission reduction is not clear enough. Taking natural gas as an example, natural gas is a clean energy source and should promote the development of natural gas in terms of policies. However, over the years, there have been phenomena such as unreasonable prices, import and domestic consumer prices. "The import price is 2.64 yuan / cubic meter, and the domestic consumer price is 2.4 yuan / cubic meter, which is not conducive to promoting production."
Faced with this situation, Guo Yunchong believes that it is time to "enlarge the energy saving and emission reduction."
Guo Yunchong suggested that we must first vigorously publicize the serious consequences of extensive economic development, publicize the grim situation and arduous tasks of energy conservation and emission reduction, thereby raising the awareness of energy conservation and emission reduction in the whole society, so that every citizen must start from himself and advocate conservation and advocacy. Energy saving and environmental protection.
Secondly, we must really adjust the industrial structure substantially, and gradually reduce the proportion of industries with high energy consumption and high pollution, such as cement and steel. We must substantially adjust the energy structure and vigorously develop green energy such as wind power and solar energy, and gradually reduce it. Coal power ratio.
At the same time, the state must formulate more stringent energy-saving standards and stricter emission standards in all walks of life, and strictly supervise law enforcement. Enterprises that fail to meet the standards for energy conservation and emission reduction are determined to stop production and stop production. It is necessary to liberalize natural gas prices, vigorously carry out exploration and development of natural gas, and increase natural gas production. It is necessary to strictly limit the export of high-energy, high-pollution products.
In terms of urban construction projects, Guo Yunchong pointed out that it is necessary to substantially improve urban planning and urban construction standards, improve the scientific, forward-looking and operability of urban planning, and its seriousness and authority; to improve urban roads, bridges and houses. Design standards for buildings to increase design life. It is necessary to improve the legislative level and the level of law enforcement in the construction of urban construction projects, and impose severe penalties, including criminal penalties, for those that fail to meet the standards and build without authorization and fail to achieve the design life. "Only in this way, we can drastically reduce the chaotic construction, greatly reduce redundant construction, significantly reduce the consumption of energy and raw materials, and significantly reduce emissions and pollution."
The ultrasonic level sensor integrates non-contact switch, controller and transmitter into one, suitable for small storage tanks. Ultrasonic liquid level sensor flexible design can be used in the integrated system or a substitute float switch, electrical conductivity and static pressure type sensor, and also suitable for the fluid flow control and chemical feed system of integrated application of ultrasonic liquid level sensor is widely used in all kinds of atmospheric storage tank, tank, small cans and small container, the pump lift stations, waste water storage tank, etc.
