What are the benefits of waste to energy? What are the specific pros and cons of waste to energy inc

Compared with other treatment methods, waste incineration has the following significant advantages: the process is simple and reliable. Waste can be incinerated without sorting and pretreatment.

The fully enclosed industrial production mode can basically not be affected by natural conditions, ensuring that the incineration plant operates around the clock and has a service life of more than 20 years. The garbage is processed quickly and the processing capacity is large. Several waste-to-energy plants have been put into operation because of the large amount of domestic waste processed, which has created good social benefits in their respective cities.

The capacity reduction after waste incineration is large. The capacity reduction is 70% to 90%, which effectively inhibits the rapid growth of garbage stockpiles, which is particularly important for large and medium-sized cities where land resources are very scarce. During the high-temperature incineration process, a large number of pathogens carried by the garbage are eliminated (especially critical for medical waste), improving the city's hygienic environment.

It realizes the conversion of chemical energy in garbage into high-grade electrical energy, turning waste into treasure. In view of the above-mentioned advantages of incineration power generation, although some experts and scholars in the environmental protection circles at home and abroad still have different views on waste incineration power generation, in the absence of a better treatment method, priority should be given to incineration treatment for energy utilization. <>

The daily operation of the waste-to-energy plant requires a large number of talents, so the most direct benefit of building a waste-to-energy plant is to provide more employment opportunities for local residents and increase jobs. Not only that, considering that the operation of the waste incineration power plant requires multiple supporting facilities, a series of supporting engineering construction will be carried out, including road construction, street lamp setting, water supply, power supply, communications, pipe network construction, etc., the completion of these public facilities will bring about the promotion and improvement of key infrastructure, and further facilitate the life of the local people and the development of enterprises. The ecological environment is getting better and better, and tourist attractions are gathering popularity.

The construction of the waste-to-energy plant will further restore the local ecological environment, increase the green ecological area, purify the living environment, bring about the improvement of the living ecological environment, and provide a good place for leisure and science popularization for the local people. Can you imagine that a waste-to-energy plant can still become a tourist attraction? Usually, the buildings in the factory area will adopt the local characteristic construction style, and at the same time, an environmental education base will be built in the park, and a new type of local industrial tourist attraction will be actively created, so that it will become a base for local industrial tourism, so as to drive the prosperity of the surrounding service industry.

Actively participate in the construction of good community relations between neighborsThe standardized and stable operation of the waste incineration power plant is of course inseparable from the harmonious coexistence of neighbors, therefore, the waste incineration power plant will also actively strengthen the connection with the community, actively integrate into the local area, and widely participate in public welfare activities, including education support, poverty alleviation, and participation in other public activities, etc., to contribute to the development of various local undertakings and be a good neighbor in the community! In just one month, "New Window of Circular Economy" took readers to learn about the "garbage siege" around us, the three major technologies to solve the "garbage siege", the development status of waste incineration power plants at home and abroad, whether there is any impact on the surrounding residents, the daily operation process, how to implement supervision, and the benefits to the surrounding residents. <>

The first problem: the scale of waste disposal in China, 420,000 tons per day, most of which is landfilled, followed by composting (kitchen waste, farm waste) and incineration. Second question:

At present (2013), there are about 500 waste-to-energy projects (in operation or under construction) in China, and almost 100 new ones are being built every year in recent years, and they are expanding from first-tier cities to second- and third-tier cities. Addendum: Waste-to-energy is not the best way to do it, and the reason can be seen in how meticulous the Japanese are in terms of garbage sorting, resource utilization, and environmental protection.

With the careful classification of the Japanese, there are still problems of waste and secondary pollution, and China's waste-to-energy power stations face many more difficulties. And the public is generally opposed to waste-to-energy power plants. At present, I am studying and promoting the integration of cement environmental protection technology, and the integration of cement environmental protection is inconvenient to say more details, hoping that the current garbage power station can be replaced on a large scale in the future.

Waste-to-energy incineration is a way to turn domestic waste into treasure, but waste-to-energy incineration has advantages and disadvantages. The main benefits are fast treatment speed, reduction, good effect, good pollution control, and high energy utilization, which are all benefits of waste-to-energy plants. Of course, there will be some disadvantages, for example, some waste incineration plants consume a lot of resources, and in addition, they must be in remote areas, so there will be some problems when selecting the site.

Incineration also produces polluting gases.

Waste incineration plants are a way for many cities to dispose of domestic waste, after all, these large cities have large populations, so there is still a lot of domestic waste generated every day. Moreover, the electricity generated by the incineration of these garbage in time can also be used for more purposes, and it can also avoid the pollution of the environment by garbage to a certain extent. However, in this process, the waste incineration plant must pay attention to its own power generation channels, and also timely treat the waste gas and dust harmlessly, so as to truly achieve the purpose of its own power generation.

In the process of construction, we must pay attention to the site selection, in addition, we must speed up our own treatment, and at the same time control the pollution, and the smoke and gas generated after incineration must be purified before it can be discharged. In addition, it is necessary to improve their energy utilization rate in a timely manner, and if they can greatly avoid the shortcomings of waste incineration plants, they can bring benefits to people's lives.

With the increase in people's demand for electricity and more and more non-renewable energy sources, it is very necessary to research and develop new energy in order to reduce people's living costs. In addition to the way of waste power generation, then hydropower, solar energy, these are good new energy, and reasonable conversion and energy storage, so that people can also use electricity in an environmentally friendly way in their daily life, and can also avoid carbon emissions.

As long as we continue to research and develop through scientific progress and break through technical difficulties, then one day people can find a great source of energy, and they can also better help the environment to improve and purify.

Waste incineration power generation, can only say that the advantages outweigh the disadvantages, because the city is overpopulated, and the daily production of garbage is particularly large, if there is no incineration power generation, the city will soon be surrounded by garbage, so waste incineration power generation is a very beneficial thing, the disadvantage is that the air pollution will be serious, but I believe that the manufacturer will solve the problem of air pollution, we don't have to worry.

The advantages are: first, it can save resources; second, it is convenient to obtain materials; Third, it is easy to handle; The disadvantages are: first, polluting the environment; the second is the trouble of classification; The third is the trouble of follow-up processing.

Waste-to-energy incineration can be: Industrial production and domestic life provide electricity demand, but it is easy to cause air pollution in the process of waste incineration power generation.

Incineration of waste-to-energy can have a minimal environmental impact if properly controlled. However, if the incineration process and the control and treatment of exhaust gas, residue and wastewater are not properly controlled, it may also cause secondary pollution, which must be paid attention to.

1) Secondary pollution after waste incineration. Garbage incineration at high temperature can be sterilized and decompose harmful substances, but when the working conditions change, or the exhaust gas leaks before treatment, the slightest carelessness in the treatment will cause secondary pollution.

The flue gas purification treatment (such as scrubber) in the process of the waste incineration station is used to remove the acid gases such as HCL and HF produced by incineration, if they are not neutralized with lime (powder or slurry) in the incineration or flue gas, these gases will be directly discharged into the atmosphere, causing secondary pollution. For example, the Shenzhen waste-to-energy power plant pollutes the surrounding environment by directly emitting acid gas when the acid gas removal equipment is not yet in operation.

2) The problem of water pollution. In garbage transportation, storage and storage, it is easy to leak and ferment, produce fermentation wastewater and filtrate, which contain some harmful sundries, and if sewage treatment is not introduced, it will cause water pollution. The wastewater, waste residue and dust of tail gas treatment should also be carefully treated to avoid water pollution.

3) Pollution of residue and dust. If the residue after waste incineration and the solid waste of tail gas treatment are not strictly controlled, they will cause secondary pollution of land resources and damage the ecological environment.

1. Eliminate the diseased pneumogens in the garbage, decompose dioxins at high temperature, and have a high degree of harmlessness;

2. Greatly reduce the amount and volume, slag and fly ash can be comprehensively utilized, which can save a large amount of landfill site;

3. Successfully replace the traditional landfill treatment method to avoid the secondary pollution caused by landfill to the environment;

4. The high-temperature steam generated by incineration can be used for heating or power generation, and can also be converted into renewable energy by making full use of waste incineration technology;

5. It can be operated around the clock and is not easily affected by the weather;

6. Replace limited resources such as coal, oil or natural gas with garbage as fuel for power generation to save natural resources;

7. Reduce greenhouse gases such as methane emissions;

8. The operation fee of incineration power generation treatment is lower than that of landfill.

Household waste can generate electricity.

At present, there are many modes of waste disposal in the world, mainly including sanitary landfill, composting, incineration, etc., each of which has its own advantages.

The investment in sanitary landfills is low, but there is a possibility of air pollution, soil pollution, and surface water and groundwater pollution. It occupies a large area and is difficult to select a site. The investment in compost is not high, but there are problems such as easy diffusion of odor sources, difficult to control heavy metal pollution, and the quality of compost is also unstable.

Compared with the previous two methods, waste incineration occupies a small area and can greatly reduce the harmful substances in the garbage; The discharged flue gas and sewage are treated, and the impure impact on the surrounding environment is very small; The heat generated can be used to generate electricity, which is the most consistent treatment method in line with the principle of "reduction, recycling, and harmlessness".

At present, the most important way to deal with domestic waste in developed countries and regions is incineration for power generation, especially in cities with scarce land resources, developed economies and large populations. For example, more than 60% in Sweden, more than 70% in Denmark, Japan, Luxembourg and Switzerland, more than 80% in Singapore, and about 90% in Taiwan, China.

The main advantages of domestic waste incineration power generation technology

First, the project land is provincial. For the same amount of waste disposed of, the land area required for a waste incineration plant is only 1 20-1 15 of that of a sanitary landfill.

Second, the processing speed is fast. It usually takes 7 to 30 years for waste to decompose in sanitary landfills, and incineration can be completed in about 2 hours as long as the melting point of the waste is less than 850.

Third, the reduction effect is good. The same amount of waste can be reduced by about 30% by landfill, 60% by composting, and 90% by incineration.

Fourth, pollution emissions are low. According to the research of the authoritative environmental research institute in Germany, the pollution generated by waste incineration is only about 1 50 of the waste sanitary landfill when the control standards are met.

Fifth, high energy utilization. Each ton of garbage can be incinerated and cracked to generate more than 300 degrees, about every 5 people produce domestic garbage, through incineration power generation can meet the daily electricity demand of 1 person, generally speaking, for densely populated, economically developed, scarce land resources should be given priority to large and medium-sized cities.
