Alkaline dry batteries don’t need to be recycled, you know-sunny came home

Alkaline dry batteries don’t need to be recycled. You know, Wei Weijia saved a lot of spent batteries with a wireless mouse, an electric toothbrush, an electronic watch, and a remote controller. Save and abandoned, and, in a dilemma, I do not know how to handle. Because cadmium is similar to calcium in bone tissue, cadmium enters the body and causes people to suffer from bone pain. In addition, zinc manganese dry cells and button batteries are coated with mercury on the zinc electrode to prevent hydrogen from exploding when the battery is not in use. So there’s a scrap battery recycling movement that started in 1970s. Haze will put everyone’s awareness of environmental protection to a very high level, waste battery recycling propaganda has been deeply rooted in the hearts of the people, with the continuous development of battery technology, whether it still needs to "hold ancient rope to the present"? Or take the public can see the battery, the widespread use of battery alkaline batteries (including but not limited to AA:5 number, AAA:7 number, C:2 number, D:1 number, 9 volt battery, alarm and other requirements for long battery life products), button batteries (electronic table), lead-acid batteries (electric bicycle the car, etc.), lithium ion battery (mobile phone, computer, camera, etc.) and uninterruptible power supply (UPS). Heavy metal pollution comprehensive prevention and control "12th Five-Year plan" pointed out that the key prevention and control of heavy metal pollutants are lead, mercury, cadmium, chromium and arsenic like metal. Most people have a positive attitude towards battery recycling, which they think is equivalent to batteries and pollution. If you tell them explicitly alkaline zinc manganese batteries from January 1, 2005 stop production of the mercury content of more than 0.0001% in October 9, 2003 released the "waste battery pollution control technology policy", "the lack of effective recovery of technical and economic conditions, waste batteries do not encourage centralized collection has reached the state of low mercury or mercury free requirements." They’ll be a little surprised. If you tell them that the Ministry of environmental protection, the national development and Reform Commission in June 6, 2008 issued under the provisions of that family in daily life waste nickel cadmium batteries and mercury oxide batteries can not according to management of hazardous waste, and can be mixed with garbage collection and disposal, they can shake. So why do we have exercise questions when we go to school to write battery recycling slogans? Is the battery recycling box just a display? Can that waste battery be discarded together with domestic waste? As the main body of the market is the most commonly encountered is zinc manganese batteries, alkaline manganese batteries, accounted for about 80%, because the mercury content has been controlled in front of the relevant provisions of the state, will not pollute the environment, do not enter the body with the food chain, they can be used as solid waste, with garbage disposal. What kind of batteries do you need to recycle? First of all, we must resolutely recycle fake and shoddy batteries produced by small workshops. In addition such as lead-acid batteries, because it contains heavy metals into the environment, may increase blood lead concentration of the human body, the impact on human intelligence; in addition to lead-acid batteries, nickel cadmium battery life, use rechargeable batteries, button batteries (not in mercury free battery General Ban range, allowing a small amount of Mercury still exists) must be in accordance with the instructions and recovery of environmental protection unit. )

碱性干电池不用再回收 你知道吗   魏伟佳   在用无线鼠标、电动牙刷、电子手表、遥控器时攒了一堆废旧电池。存亦忧,弃亦忧,左右为难,不知如何处理。   由于重金属镉与骨组织的钙类似,镉进入人体会使人患上骨痛病,另外锌锰干电池和纽扣电池会在锌电极上镀一层汞来防止电池在不使用时产生氢气而导致爆炸。所以才会有起始于20世纪70年代的废旧电池回收运动。   雾霾将大家的环保意识提到了很高的层次,废旧电池回收宣传已深入人心,随着电池技术的不断发展,是否还需要“执古以绳今”呢?还是先说一下大众能看到的电池,普遍使用的电池有碱性干电池(包括但不限于AA:5号、AAA:7号、C:2号、D:1号、9伏电池,多用于报警器等要求电池寿命较长的产品),纽扣电池(电子表等),铅蓄电池(电动自行车,汽车等),锂离子电池(手机、电脑、相机等)以及不间断电源(UPS)。《重金属污染综合防治“十二五”规划》指出,重点防控的重金属污染物是铅、汞、镉、铬和类金属砷等。   大部分人对电池回收的态度是肯定的,他们认为电池和污染对等。如果你告诉他们于2003年10月9日发布的《废电池污染防治技术政策》中明确规定从2005年1月1日起停止生产汞量大于0.0001%的碱性锌锰电池,“在缺乏有效回收的技术经济条件下,不鼓励集中收集已达到国家低汞或无汞要求的废一次电池。”他们肯定会略显诧异。如果你再告诉他们环境保护部、国家发改委于2008年6月6日下发规定:家庭日常生活中产生的废镍镉电池和氧化汞电池可以不按照危险废物进行管理,而可以随生活垃圾混合收集和填埋时,他们可能会摇摇头。那为什么上学时会有让我们写电池回收宣传语的习题?那随处可见的电池回收箱只是摆设?那废弃的电池真可以随生活垃圾一块儿丢弃吗?   作为市场主体也就是我们最常碰到的是锌锰电池、碱锰电池,占比80%左右,由于其汞含量已经在国家有关规定面前得以控制,不再会污染环境,也不会随着食物链进入人体,大家可以将其作为固体废弃物,随生活垃圾处理。   那需要回收的是什么样的电池呢?   首先,对小作坊生产的伪劣电池我们要坚决回收。另外如铅酸电池,因其含有重金属铅,放入环境可能增高人体的血铅浓度,对人的智力造成影响;除了铅酸电池,生活中用到的镍镉电池、可充电电池、纽扣电池(不在一般干电池的无汞禁令范围,仍允许少量汞的存在)等必须切实依照环保单位的指示回收。   或许你听过或者有过电瓶车电池被偷的经历,这是因为一个铅蓄电池能卖100多元呢;2010年1月1日起实施的《清洁生产标准 废铅酸蓄电池铅回收业》指出,相关资质企业铅电池的回收率必须达到95%以上,一些设备先进的企业甚至能达到98%,这是电池回收的一个正面例子。但是,由于铅酸电池含有约74%的铅极板、20%的硫酸,巨大利益的存在促使一些小作坊偷偷进行回收拆解,直接拆下铅极板,倾倒废酸,回收率不高不说,还会导致水和土壤的污染,溶于酸中的铅离子会进入环境。这也为废旧电池回收敲响了警钟,回收是好事,监管是大事,不能在回收污染物的同时又造成污染。   时代在进步,我们的环保意识也应进步,与此同时,我们的信息意识也应当进步,面对早已低汞或无汞的干电池,我们不应该还拿当初宣传时候的标准对待。我们要做的是减少镍镉电池等含有重金属污染的电池的使用,不断发展技术手段,逐步淘汰含重金属的电池,或寻找其替代品;同时,要呼吁政府早日完善法律,建成废旧电池回收体系,废旧电池的回收不仅可以减少环境污染,还能节约大量的一次性矿藏。资源的循环利用,环境的生态宜人才是我们最想看到的结果。   如果下次不开心,可以尝试着扔一些碱性干电池哦。   (作者系中国科学院大学博士研究生)相关的主题文章:
