Olympic birth is expected to be energy-saving opportunities for adjustment of energy structure

Olympic birth is expected to be energy-saving opportunities to adjust the energy structure in terms of the Green Olympics, environmental protection is a top priority. According to the requirements of clear water and blue sky in Beijing now need to raise the environmental indicators, environmental protection must be bigger cake,[link widoczny dla zalogowanych], environmental improvement and urban greening will become the new business opportunities. Reduce air and noise pollution, solve the 2O will be completed by 2007 major projects in key environmental management, urban refuse will implement treatment and disposal of urban sewage treatment rate reached 90% of industrial pollution, automobile exhaust pollution, coal pollution and other pollution control efforts will continue to increase. Beijing's energy structure will quietly shift from coal to natural gas, wind, solar and other clean energy sources. By 2007, clean energy use in Beijing will reach 80%; Beijing will also build 12 sewage treatment plants,[link widoczny dla zalogowanych], the city's sewage treatment capacity per day of total 2.68 million t, processing rate of 90%; all the facilities of the Olympic village,[link widoczny dla zalogowanych], geothermal air conditioning and heating are the main energy hot water bath and lighting to solar and wind energy. As the Olympic Games pushed, the next two or three years is the environmental protection industry to adjust, reshuffle the important period. At present, the production of environmentally friendly products around 10,000 enterprises,[link widoczny dla zalogowanych], but small, scattered mainly low-level, redundant construction and more. Compared with developed countries, China's technological level of environmental protection equipment behind the largely 15 ~ 20a. Only a few environmental treatment technology and equipment to 8O late or early 90s the international level. In the high concentration organic waste water and urban sewage treatment equipment such as large areas of disparities; in the comprehensive utilization of solid waste, the lack of large complete sets of processing equipment; in particular, automated monitoring equipment online and fast development of more backward, high-precision almost all sharp instruments and equipment imported. China's environmental protection industry goal is to billion in annual output value of more than 1O, and more than 10 billion yuan in output value appears large environmental companies. To achieve long-term development goals of environmental protection industry, no doubt the Beijing Olympics is to provide a favorable opportunity.
