At present, all dry batteries are mercury-free alkaline batteries, which meet the national standards, and it is ok to lose face to domestic garbage without increasing the environmental burden. If collected and treated, it will be harmful to the environment.
Such as lead batteries, rechargeable batteries, etc. , or should be handed over to a professional recycling station.
Question 2: How to deal with the increasing output of waste battery waste correctly is making the planet we live in overload. The endless stream of public hazards and garbage siege has sounded the alarm for us. How to realize harmlessness, reduction and recycling has become a top priority. Resource dislocation is a new understanding of garbage in recent years. The implementation of garbage classification will make the best use of recyclable garbage and turn waste into treasure.
In terms of volume and weight, waste batteries are insignificant in domestic garbage, but their harm is very great. Batteries contain heavy metals such as mercury, cadmium and lead. Mercury is very toxic, and lead can cause nervous disorder and nephritis. Cadmium mainly causes kidney injury and bone diseases-osteoporosis, rickets and fractures. If waste batteries are buried together with domestic garbage, heavy metals may pollute groundwater and soil over time.
The usage of batteries in our life is increasing rapidly, and it has penetrated into every corner of our life and work. Walkman, BP machine, mobile phone, camera, calculator. At present, the national battery consumption is around 7 billion. It is predicted that by 2000, the battery consumption of BP machine alone will reach 65.438+0.55 billion. If these batteries are not handled properly, they will directly or indirectly endanger people's health. Implementing and advocating the classified collection of used batteries has been recognized by more and more people, and has received more and more attention, support and participation-instead of dispersing pollution, it is better to treat it centrally.
Starting from me and starting from every little thing around us is our motto. Caring for the surrounding environment and participating in the classification and recycling of used batteries is the responsibility and obligation of each of us. Individual behavior may be insignificant, but the strength that unites each of us is enough to support a civilization, a civilization born out of nature and a sustainable civilization.
1. composition of battery: composition of dry battery and rechargeable battery: zinc sheet (iron sheet), carbon rod, mercury, sulfate and copper cap; The battery is mainly composed of lead compounds. For example, 1 waste zinc-manganese battery weighs about 70g, including 5.2g carbon rod, 7.0g zinc skin, 25g manganese powder, 0.5g copper cap and 32g others.
Second, the harmfulness of waste batteries: the harmfulness of waste batteries is mainly concentrated on a small amount of heavy metals, such as lead, mercury and cadmium. These toxic substances enter the human body through various channels, and long-term savings are difficult to eliminate, damaging the nervous system, hematopoietic function and bones, and even causing cancer. Lead: diseases such as nervous system (neurasthenia, numbness of hands and feet), digestive system (dyspepsia, abdominal cramps) and blood poisoning. Mercury: Mental state change is the main symptom of mercury poisoning. Rapid pulse, muscle tremor, oral and digestive diseases. Cadmium and manganese: mainly harm the nervous system. 3. Ways for waste batteries to pollute the environment: The components of these batteries are sealed inside the battery box during use and will not affect the environment. However, after long-term mechanical wear and corrosion, heavy metals, acids and alkalis will leak out, enter the soil or water source, and enter the human food chain through various channels. The process is briefly described as follows: pool soil microorganisms, animals, circulating dust, crops, food, human nerve deposition.
Heavy metals ingested by other water plants and food-borne organisms from the environment can accumulate in thousands of higher organisms step by step through the biomagnification of the food chain, and then enter people's bodies through food and accumulate in some organs to cause chronic poisoning. Water disease in Japan is a typical case of mercury poisoning. 4. Other manifestations of the harm of waste batteries: At present, the treatment of domestic garbage in the world is mainly sanitary landfill, composting and incineration. The pollution of waste batteries mixed with domestic garbage in these three processes is reflected in landfill: the heavy metals of waste batteries pollute water and soil through infiltration. Incineration: waste batteries corrode equipment at high temperature, and some heavy metals volatilize in the fly ash of incinerator, causing air pollution; Heavy metals accumulate at the bottom of the incinerator, polluting the ash. Composting: The high content of heavy metals in waste batteries leads to the decline of compost quality. Reuse: reverberatory furnace metallurgy is generally used. Although the process is easy to master, the recovery rate is only 82%, and the rest of the lead appears in the form of gas and dust. At the same time, sulfur dioxide in the smelting process will enter the air, causing secondary pollution and directly endangering the health of operators.
Harm of waste batteries: Mercury discarded from natural batteries will slowly overflow from the batteries, enter the soil or water source, and then enter the human body through crops, damaging the human kidneys. In >;
Question 3: How to deal with the used batteries at home? There is no recycle bin around home! Praise it first. If you have innovative ideas, do a charity.
Question 4: What should I do with the used batteries at home? Honey, your behavior is right. Although the battery is dead, the pollution is serious. You can look for trash cans in the street. Now many trash cans have special places to collect waste batteries. Alas, social recycling is not perfect now. Let's work harder and make our own efforts for a better environment. Dear, have a happy day.
Question 5: There are many used small batteries at home. What do you do with them? Just throw it away? First, we should prevent and control from the source and promote mercury-free batteries. Nine ministries and commissions, including China National Light Industry Federation, the former State Environmental Protection Administration and the State Bureau of Quality and Technical Supervision, jointly issued the Regulation on Restricting Mercury Content in Battery Products on 197 12-3 1, requiring 12-00 to prohibit domestic production and distribution of batteries with mercury content greater than 0.025% of the battery weight. Since the release of the "mercury restriction order" for batteries, Chinese battery enterprises have actively innovated production technology and improved raw material formula. At present, the batteries produced by regular battery manufacturers have basically realized mercury-free
Second, the national policy does not encourage the centralized collection of used batteries. The former State Environmental Protection Administration, the National Development and Reform Commission, the Ministry of Construction, the Ministry of Science and Technology, the Ministry of Commerce and other five ministries and bureaus jointly issued the "Technical Policy for the Prevention and Control of Waste Battery Pollution" on June 9, 2003, stipulating that centralized collection of waste disposable batteries that have reached the national requirements of low or no mercury is not encouraged under the technical and economic conditions of effective recycling. In addition, the National Catalogue of Hazardous Wastes jointly issued by the Ministry of Environmental Protection and the National Development and Reform Commission on June 6, 2008 stipulates that waste nickel-cadmium batteries and mercury oxide batteries generated in daily life may not be included in hazardous waste management. The above provisions are the requirements after scientific argumentation by relevant state departments and experts. Waste batteries can be recycled in different ways, and citizens can put them into regular domestic waste collection boxes and enter the regular domestic waste landfill in our city together with domestic waste, which will not cause environmental pollution.
3. The pollutants in commonly used dry batteries are mostly solid, and most harmful substances are insoluble in batteries or thrown into the environment. The migration or diffusion of pollutants from the inside to the environment is a very slow process, especially mercury. Therefore, the scope and extent of its pollution are limited. As early as the early 1980s, Japan Battery Industry Association commissioned Fukuoka University to study the migration of mercury in waste batteries in 15 years. They used different landfill methods to fill waste batteries such as zinc manganese, alkaline zinc manganese and mercury oxide in different landfill columns, and monitored the mercury content in the air of leachate and landfill columns and the mercury concentration in the air when the landfill columns disintegrated, and made a comparative analysis. In 10 year, the amount of mercury migrating with leachate in the experimental column only accounts for 0.08%-0. 1% of the total mercury, and the amount of mercury diffused through the atmosphere only accounts for 0. 1%. The impact of mercury in waste batteries buried with garbage on the environment is not as serious as advertised by some media.
Question 6: What about the waste batteries at home? It only takes a few steps to turn waste into treasure.
Students pour waste batteries into the waste battery recycling bin.
"I'm really happy to take part in this environmental protection activity, because I know that these batteries are no longer homeless as before, and they can also turn waste into treasure!" District students in Grade Two of Xiaoyuan Middle School told reporters excitedly. On the special day of "Earth Day" yesterday, the "Environmental Action for Recycling Used Batteries" jointly sponsored by Guangzhou Environmental Protection Education Center was officially launched.
According to reports, the biggest difference between this battery recycling operation and the past is that the recycled waste batteries will not be handed over to the sanitation department for landfill treatment, but will be sent to a waste recycling company in Panyu District for crushing, sorting and forging to become useful metals for reuse. This indicates that the recycling of waste batteries in Guangzhou has achieved an important transformation from "alkali damage" to "resource utilization".
The "environmental protection action of recycling used batteries" will be carried out in schools in the whole city at first. The first batch of schools in Haizhu District 100 will be selected as pilots, and then spread to the community and gradually spread throughout the city. A waste recycling company in Panyu District, which is responsible for recycling waste batteries, will also set up special waste battery recycling bins in the above areas for a long time, and send dozens of vehicles to recycle waste batteries discarded by citizens.
According to Chen Guoan, the chief engineer of a recycling company in Panyu District, taking the battery in 4 yuan as an example, the value of recovered useful metals can reach 3.2 yuan, which is equivalent to 80% of the battery cost. According to reports, at present, Guangzhou consumes about 500 million batteries every year, equivalent to about 2,500 tons, of which 80% are discarded after use.
Question 7: Is the waste battery harmful to the environment? Why? Where should I throw the used batteries at home and what should I do with them? Batteries contain lead and some contain mercury. Lead and mercury are heavy metals and will pollute the environment. Just throw the sorting bin. Some substances in the battery can be recycled, such as graphite.
Question 8: What should be done with the used batteries in ordinary households? So as not to pollute the environment, put it away and give it to the place where the battery is collected. For example, some trash cans have a small box for recycling batteries in the middle. Some supermarket counters also have collection boxes. Some community doormen also accept it.
Question 9: How to deal with waste dry batteries? I live on campus, and the school has a recycling bin for used batteries, all of which are thrown in it.
Don't throw the battery about, otherwise it will cause heavy metal pollution. If you are at home, go to the supermarket near your home. At present, Carrefour and other large supermarkets will set up waste battery recycling bins.
