"China's brick and tile industrial clay solid bricks occupy the main body of the wall material has not fundamentally changed." Pei Xiaofei, director of the Standards Division of the Ministry of Environmental Protection's Science and Technology Standards Department, said that the overall production level and product quality of the brick and tile industry are not high and still There are many ills. Small-scale enterprises with an annual output of less than 10 million standard bricks account for about 45% of the total number of brick and tile enterprises. The task of adjusting the industrial structure is still very urgent.
Although the brick and tile industry is one of the industries that uses industrial waste, especially combustible waste, it is an industrial sector mainly based on the production of sintered bricks and kiln. 10 million standard bricks or less) account for the majority of the industry, which is far from the requirements of energy conservation, emission reduction and sustainable development. Therefore, the development of energy-saving emission reduction technologies and equipment is a key issue facing the brick and tile industry.
How much pollution can the brick and tile industry bring? Pei Xiaofei introduced to reporters that the total amount of bricks and tiles in China is relatively large. By the end of the "11th Five-Year Plan" period, the total output of bricks and tiles is about 1 trillion yuan / year, of which the output of clay solid bricks is about 400 billion yuan / year and the output of clay tiles is nearly 400 100 million pieces / year. Due to the large number of enterprises, although the emissions of air pollutants from a single enterprise are small, the total emissions of the entire industry are relatively large; environmental management is more passive due to the lack of targeted industry standards; economic and technical reasons make the end-of-government level Not high, poor governance.
"In China, the environmental pollution problem has not yet attracted enough attention from the brick and tile industry." At present, the state has not yet introduced such a policy. The existing brick and tile factories have basically not adopted governance measures such as flue gas purification and desulfurization. Bag crushers were used in the process of raw material crushing, and some new coal gangue brick factories were installed in flue gas desulfurization facilities.
The relatively backward environmental protection measures of the brick and tile industry have also brought some environmental pollution problems.
For example, Hangjiahu area is an important sericulture base in China. Due to the construction and expansion of a large number of brick and tile factories and other fluorine-exhausting enterprises, since the early 1980s, fluorine pollution has become one of the prominent factors affecting local sericulture production. There have been various levels of fluorine pollution incidents, with huge losses.
In addition, the contribution rate of the brick and tile industry to atmospheric pollution cannot be ignored. According to estimates, in 2010, the emissions of soot and sulfur dioxide in the brick and tile industry reached 916,000 tons and 1.77 million tons, respectively, accounting for 11.0% and 8.1% of the country's total emissions.
At present, China's brick and tile industry is developing rapidly in science and technology, and enterprises have entered an important period of transformation that has never been seen before. The brick and tile industry urgently needs access policies to enhance the sustainable competitiveness and sustainable development of enterprises. "The improvement of industry standards is not only the need to improve the quality of the atmospheric environment, but also the need to transform and upgrade the brick and tile industry."
