He Xinwen, deputy of the National People's Congress and deputy director of the Economic Operation Department of Southwest Computer Co., Ltd., said that ordinary citizens rarely know the dangers of waste energy-saving lamps to the environment, nor do they form the habit of properly disposing of used energy-saving lamps. At present, the pollution caused by the treatment of waste energy-saving lamps in China and the social harm caused by the joint use are difficult to measure.
At present, China's lighting power accounts for about 12% of the total electricity consumption of the society, reaching 410 billion kWh, equivalent to the electricity consumption in the UK for one year. In order to save electricity consumption, the state has adopted financial subsidies to promote high-efficiency lighting products in recent years. If energy-saving lamps can be promoted nationwide, China will save more than 300 billion kilowatt-hours of electricity every year. In 2009, the central government provided 600 million yuan of special subsidies to promote 120 million energy-saving lamps, boosting consumption by 1.5 billion yuan, saving 6.2 billion kilowatt-hours, reducing carbon dioxide emissions by 6.2 million tons, and sulfur dioxide by 62,000 tons. / kWh calculation, can save electricity costs of 3.1 billion yuan.
At present, there are nearly 2,000 energy-saving lamp manufacturers registered in China, with an annual production of 2.4 billion energy-saving lamps. Nearly 85% of energy-saving lamps in the global market are produced in China. Most energy-saving lamps produced by energy-saving lamps are mercury-containing. Energy saving lamp. An energy-saving lamp tube contains an average of 0.5 mg of mercury (only a few products can do about 0.25 mg), while 1 mg of mercury immersed in the ground will cause about 360 tons of water pollution. Mercury is a liquid silver white metal at room temperature, commonly known as mercury, which evaporates at room temperature. The fluidity is large, and the splashed ground is very fragile into small mercury beads, which is difficult to remove, is pervasive, and is easily adsorbed by walls and clothes, and becomes a source of pollution that continuously pollutes the air. Mercury vapor easily enters the body through the respiratory tract, and long-term exposure to excessive mercury can cause poisoning. Chronic mercury poisoning can make a person's personality timid, shy, lonely, bored, oral mucosal congestion, red gums, loose teeth. In severe cases, it may cause people to tremble. Frequent exposure to mercury can also cause leukemia.
At present, when dealing with energy-saving lamps, many countries including China have not considered the harm of mercury to the environment. Although China issued the “Technical Policy on Prevention and Control of Hazardous Waste Pollution†in 2001, it only encourages the government to establish a fluorescent tube recycling and treatment agency. There is no regulation on the recycling of energy-saving lamps, and even many cities do not have professional recycling sites at all. Under such a large-scale promotion of energy-saving lamps, the number of discarded energy-saving lamps produced cannot be counted. At present, the treatment methods of domestic waste energy-saving lamps are mainly mixed with domestic garbage, resulting in pollution and economic benefits. Social harm is even more difficult to measure. To avoid mercury contamination, it is recommended that:
First, actively improve the production technology of energy-saving lamps, develop mercury-free or low-mercury energy-saving lamps, learn international advanced technology, and replace liquid mercury that is easy to pollute the environment with solid mercury.
Second, set up collection points in shopping malls and residents' communities, and the state will fund the recycling of waste energy-saving lamps.
Third, establish an abandoned energy-saving lamp treatment system to ensure that the recycled energy-saving lamps can be safely disposed.
Fourth, strengthen the publicity of the dangers of waste energy-saving lamps, so that the public can establish the concept of recycling energy-saving lamps.
