Burning garbage power, the technology is not a problem

Energy company in the waste incineration power plant project manager about garbage disposal problem Liu Jianping burning garbage power, the technology is not a problem

Recently, Beijing Municipal city rongwei outgoing messages will be redrafted previously raised social concern £ waste incineration plant site.

In fact, recent on garbage incineration argument has not been broken, and many places for related project planning and construction, a series of group events. Reporter to interview the Chinese energy-saving investment company waste incineration power plant project General Manager Liu Jian, he technically as we re-establish the garbage incineration. Liu Jian-Frank responded to our questions, stressed that the Chinese waste treatment technology is no problem, the problem is the "other side".

1 main public garbage power

Beijing News: "energy saving" did what garbage power project?

Liu Jian: has built and built 8 garbage power projects.

The biggest is in Chengdu. Construction started this year 1800 tons of garbage a day. We do not have a project in Beijing.

Beijing News: garbage power while processing waste and generate electricity two benefits, it is the main benefits?

Liu Jian: is the public projects.

Garbage disposal there are three main ways: landfill, composting and incinerating. Therefore, the garbage incineration is one of the means of waste disposal. Waste incineration is harmless, waste minimization and recycling. I think the "three" core or garbage disposal harmless, reduction, if resources better. Incineration, landfill volume will be reduced by 80%-90%. Now, Beijing day produces more than 1.5 million tons of garbage, volume 2.5 million cubic meters. No you buried.

Beijing News: burning leaves and things are emitted? what hazardous substances inside?

Liu Jian: key technologies for municipal solid waste incineration is waste the flue gas trea

tment. This investment to a total investment of approximately 1/3. After the flue gas treatment, emission targets should be able to reach the national standard of garbage disposal. For example, the provisions of the second British emissions must not exceed 1 nanograms per cubic meter, Euro II standard is per cubic metre 0.1 nanograms. In fact, a lot of waste incineration plants are able to meet Euro II standards. The remaining 10% is slag. Slag is like our home stoves burn-out of the ashes. It must be non-toxic harmless and can be used to clean the brick or paving. There is also the chimney from the ashes, which has certain dangerous substances, in accordance with the regulations to solidify into square blocks, landfill. Ashes of volume only about 2% of the original spam — 3%. In fact, the incineration plant is afraid and landfill of factory built together, because the smell.

Beijing News: this standard is developed by who to monitor?

Liu Jian: this standard is developed by the national environmental protection departments.

Our factory has a monitoring instrument, and the local environmental protection Bureau is alive. They can monitor sulphide, nitrogen oxides or something harmful gas emissions, but the second British can't online testing, to periodically sample to the lab testing, detection cycle to a month, usually twice a year. Internationally.

Beijing News: Environmental Department have representatives in factory? monitoring instruments will not be obscured?

Liu Jian: not currently.

EPA approval of an acceptance report and then is a real-time monitoring. We hope that the national legislation can be more perfect. Now the problem of waste incineration and power generation more interesting, in fact, every industry have this problem. For example, drain, often check the man left, high pollution of the valve is opened. Believe that after the national policy will be more perfect.

2 unclassified

does not increase the emissions

Beijing News: waste incineration plant burning of garbage is categorized?

Liu Jian: my most garbage are not categorized.

Beijing News: this will result in the flue gas purification problems?

Liu Jian: in any case we have to meet emissions standards.

Unclassified spam really increased waste disposal costs. In the future if the waste can be achieved very good level, our cost will be reduced. Now and over time, the technology itself is not a problem, is the question.

Beijing News: How did the burning trash?

Yes want to spray oil?

Liu Jian: waste incineration has two major mainstream technology: Grate furnace technology and circulating fluidized bed technology.

Grate furnace started to to injection, once started up to continue normal operation. Circulating fluidized bed technology should always to garbage burning coal help Riga. This is a national, coal must not exceed 1/20, plus more became "a small thermal power", the cost is not appropriate. Now advanced circulating fluidized bed can also be done at first, but then Tim coal there is no need to add coal.

Beijing News: sludge combustion power we not too familiar with, but recently because of a series of Foshan events began to stand out, you can talk about sludge combustion power generation is going on?

Liu Jian: our company in Shaoxing did a mixed sludge and waste incineration plant.

In fact, future sludge incineration will have greater development. However, the situation is very complex of sludge, such as wastewater treatment plant of sludge, the industrial production of river sludge, sludge, sludge per species, processing methods. We in Shaoxing of sludge incineration projects, dealing with paper mill sludge, high calorific value. Sludge incineration should be dry before disposal, to rid the water of 40%. The technology more trouble. Burn after only a little gray left.

Beijing News: waste treatment really just a technical problem, how do you see those "non-technological factors"?

Liu Jian: my garbage disposal this development is very fast, so many problems.

The beginning is the landfill, many are not standard landfill factory. In recent years to start development of waste incineration. Market, there are various enterprises to enter this area, although as long as there is sufficient investment in technology to meet the requirements, but some people in order to boost your profit, damage to the environment. We hope that the country as soon as possible the relevant policies, strengthen supervision and standardize industry behavior, heightening the entry threshold, are not fulfilled in respect of the demolition. I personally think that there are a lot of social responsibility, Directorate do such a project would be more appropriate. In fact, we are also "bad company" victims in Shenzhen to do items next to two small waste incineration plant, very bad, great views of the residents, we are also very difficult to do. These problems are bad, might also be a good thing, because it allows countries to pay more attention to these issues.

3 factory must quickly

Beijing News: State regulations waste incineration plant safety distance?

Liu Jian: in accordance with the provisions of the national environment protection sector, in the residential population 300 meters can be built outside the waste incineration plant.

Beijing News: even if environmental indicators can be achieved and that for a local resident, or do not have this plant is better than the factory.

So how should refuse incineration plant site?

Liu Jian: are you sure this is the case.

Everybody knows that waste does not deal with no, but who do not want on your own doorstep. Fortunately, the land in the West are more able to landfill. South-Eastern regions of the city, you're essentially nolocal landfill, incineration plants had built. Because of the incineration plant covers an area of relatively small, as long as the area around 100 acres. And landfill space is much larger, and often two or three years is filled. We need only the amount of landfill ashes, landfill is very small.

I personally think the Government should plan well, after you establish fast.

This is the experience of Korea and other countries. China occurs waste incineration plant construction raised many group event, reason is planning down, spend a long time to go down. In this process, the surrounding real estate has been up. Then start building incineration plant, developers and tenants have comments. In fact, some of the events behind the real estate interests pushing hands, the situation is very complex.

Beijing has been planning a five waste incineration plant, £ a, a, nangong asuwei has one.

So many years, just completed a gaoan Tuen municipal solid waste incineration plant. Gaoan Tuen by the early 1990s began to build up, beginning around nothing, then the surrounding real estate with a large, construction waste incineration plant will be a problem.

Beijing News: If, as in the area of Jiangsu and Zhejiang, all over the House, there is no space to build, what should we do?

Liu Jian: it is necessary to establish a democratic mechanisms, hearings, to the public.

Countries should also intensify its awareness, inform the public as long as you comply with the national standard of living in the waste incineration plant peripheral. In some countries, the Government will refuse incineration plant, 300 meters from residents to compensate. For example, Korea's waste incineration plant will give the surrounding inhabitants low heat, there are other compensation, the waste incineration plant 300 meters of a House to buy.

Many problems are not technical problems, the waste incineration plant in China is not fulfilled.

Korea has been a longprocess to reach this level, my garbage disposal there is a long way to go.
