A long-term study of electronic products on the impact of environmental pollution experts, a cell phone battery pollution load of waste, equivalent to 100 ordinary batteries. Used as a traditional cell phone, contain potentially harmful substances to the environment at least 20 species. Researchers have made an experiment, an old cell phone batteries, can contaminate 60,000 liters of water. "60,000 liters of water enough to fill three standard swimming pool." Cell phone batteries on the market today, the main points of nickel-cadmium batteries, nickel metal hydride batteries and lithium-ion battery 3 species. "One of nickel-cadmium batteries contain heavy metals as cadmium, harmful to human body. Have long contaminated, there may be emphysema, bone changes, anemia and other symptoms and may even lead to paralysis." The experts just such an account: reset the cell phone, the average life of 5 years (excluding its been sold several times in fact, not many cell phones can be used for 5 years. the authority of environmental protection organizations in Hong Kong a statistical average life of a cell phone for 600 days), each cell phone only one battery. Hefei urban resident population of 300 million or more (according to the Hefei Economic and Social Statistics Report 2009), calculated according to three million.As the recycling of used batteries can not find the departments and enterprises, recycling of used batteries often encounter "homeless" situation. Such as Jinan Ginza shopping on duty since 1998, recycling of used batteries, so far has recovered hundreds of thousands of festival, in addition to a business as part of the treatment trial, the rest still on the mall. Beijing was established in 1998 the usefulness of garbage recycling center, over the years has collected 400 tons of used batteries, still has most of the stack containers in the recycling center [4]. Recycling of used batteries only to move a home together in one place, but the pollution itself, this method is not desirable. cell phone jammer still can be used in such serious locations as the party and government institutions, theaters and so on which need tranquility.cell phone jammer components mainly include: main machinery, antenna, power supply adapter. Recycling of waste batteries has been difficult to handle, it is because our country has not yet established a comprehensive network and system for efficient recycling, waste battery processing industry has not established a set of industry, large-scale and specialized mode of operation. Although various types of waste processing technology has a lot of batteries, but some of the more mature, but a variety of economic factors constraining the development of battery disposal industry. Low recovery rate for disposal of batteries, long cycle efficiency is difficult to have too many economic benefits, even profitable, but also lose money, it is difficult to attract investors, so it is difficult to form an industrial scale, the scale can not be without realization of benefits.
