Reducing agent can be used steel pickling wastewater formulated by Waste. Ni-MH batteries, lithium-ion batteries with new development in recent years, handheld phones and electronic devices get a lot of applications. In Japan Zhangmutou new original IC electronic products, Ni-MH battery production in 1992 amounted to 18 million Zhangmutou new original IC electronic products in 1993 amounted to 70 million by the year 2000 accounted for nearly 50% market share. It is expected that in the near future Zhangmutou new original IC electronic products, will be a lot of waste generation Ni-MH batteries. These waste Ni-MH battery positive and negative material contains a lot of useful metals, such as nickel, cobalt and rare earth. Therefore, recycling Ni-MH batteries is very useful, on their recycling technology also in active development. It is understood that, with mobile phones, computers and personal digital cameras and other home electronics products are increasingly popular, greatly accelerate the replacement rate, as a global information technology leader in the United States, the number of discarded consumer electronics which has become more substantial. According to statistics, in 2005 the United States discarded television sets, personal computers, mobile phones, printers, scanners, fax machines and other electronic products, weighing two million tons, of which 80% to 85% mainly discarded in the landfill, the only 15 to 20% is recycled and reused, the proportion of municipal solid waste in traffic has been close to 2%. Experts fear Zhangmutou new original IC electronic products, electronic products as lead, mercury, cadmium and brominated flame retardants and other harmful substances improper handling will harm the environment. To this end, the United States in the "recycle" waste aspects of consumer electronic products, began to do a lot of work and achieved some results.
