Where can we pile the rubbish 4 years later?

Where can we pile the rubbish 4 years later?
The whole city produces 18,400 tons of rubbish every day, still 8% of the speeds are increased progressively with every year for the producing amount of the rubbish, will all fill-up within 4 years in the existing rubbish landfill yard. This is the difficult problem that garbage disposal meets at present in this city. This city once faced the difficult problem of encircling a city of the rubbish at the beginning of the eighties of last century. But a different one, want, give one in change can landfill extremely difficult in land of rubbish now, and build rubbish and burn the factory, this kind of methods that can reduce rubbish landfill quantity in a large amount, approval of peripheral residents that but can't obtain rubbish and burn the factory and select site.
Phenomenon
Rubbish classification performs practically no function
Having finished suppers, Zhao Li pours the leftovers leftovers into the disposal bag, then throw into the garbage bin in one's own floor.
Improvement of the standard of living and inflation of resident population, it influences rubbish of this city to produce two great important factors of quantity to become. The data reveal, since last year, the residents in Beijing and the producing amount of unit domestic rubbish reached 18,400 tons daily, rubbish increment still rises continuously according to the speed of about 8% for every year at present. While the producing amount of the rubbish increases, handling capacity is insufficient seriously. The daily handling ability that Beijing garbage disposal factory designs is only 10,400 tons at present, it is real on day handling capacity is 17,400 tons, phenomenon of running of field overload of rubbish is serious. According to this speed, after 4 years, the rubbish landfill yard of the whole city will be fill-uped, the whole city will face having no condition of throwing in the rubbish in the place. The rubbish encircles a city, this vocabulary that once appeared, become the focus that people discussed again.
Zhao Li throws the rubbish away to seldom classify now. He said, once did the classification by oneself, divided the newspaper, plastics in the rubbish out, the melon seed peel, fruit peel is put in another bag. But found later, the sanitation vehicle was poured and transported after together of rubbish that will already divided while transporting the rubbish, have injured the enthusiasm of one's own rubbish classification seriously. He thinks, rubbish classification is to solve the method of the rubbish predicament of this city at present. If residents classify the rubbish, personnel classify the sanitation while transporting the rubbish, some useful wastes can be recycled, the rubbish amount sent to the landfill yard finally is certain to reduce.
170,000 persons who glean and collect scraps, as rubbish classification
Compared with harmless treatment of the rubbish, rubbish recycle treatment and reduction are the first-selected route of the problem of encircling a city of more high-levelly solving the rubbish. The retrieving amount of old and useless goods and materials reached 4 million tons last year, volume was equivalent to two Jingshan.
According to the introduction of Wang Weiping, vice chief engineer of committee of the municipal appearance of the city, more than 170,000 people retrieve the money made as the source of income by the rubbish in Beijing. These personnel help Beijing to realize the old and useless goods and materials are utilized, has reduced final rubbish handling capacity too. "If succeed in limiting packaging, the producing amount of the rubbish of this city will be reduced by 15%, if implement the clean vegetables and go down town, ban the market of farm produce, restaurant in the urban range and solve the leftovers leftovers problem, rubbish of this city can be reduced by 22%. "
The reduction of rubbish is a complicated and long-term course, depend on the improvement of people's consciousness, and ban the market of farm produce, will lead to the fact a lot of people's life cost increases. Go on classifying and recycling very exhaustive to rubbish, some rubbish composition unable to utilize still, need dealing with.
Scene
The categorised rubbish in the transfer post is automized
In Xiao large-scale to abolish, sort, stand king, head of transfer post, great to it seems while being wise while being firm base Wu, whether residents go on rubbish classification, do not influence sorting the work standing, sort technology automatically through various, original ecological rubbish 90% composition can be separated out, the infrared light can screen the rubbish composition and classify automatically in 1/3 seconds when sorting the apparatus.
HongZhe Wang introduce Xiao large-scale to abolish, sort, stand transfer post there are many kinds of sorting apparatuses while being firm base Wu, include all to sort line, apparatus get to light rubbish, reflect different infrared light that come back according to rubbish, only taking 1/3 seconds can screen and sort the rubbish composition. Various automatic processing lines can be divided and elected many kinds of recoverable things, timber of major possession, waste plastics, scrap iron, paper,etc. can realize the wastes are utilized again; Rubbish of kitchen, leaf, outer leaf,etc. turn into fertilizer after treatment; Some unable to utilize material that can burn, sort, come out, send the rubbish to, burn the factory and come and generate electricity; Remaining rubbish that really can't use such as dregs, fly ash,etc., send the landfill yard of the rubbish to and go on landfill generally, also can become the material which is made the brick.
The rubbish is turned into resources Still need the classification again
The reporter sees, the plastic object of black of a beacon shape is being put on king's desk of the great wise office. Wang HongZhe introduces, this is a part of a container bottom tray, retrieve the plastic material and make out with the rubbish.
He introduces, there are a lot of kinds of plastics in the rubbish, such as ordinary plastic bag, a little harder plastic file, plastic bottle,etc., it is seriously different plastics. If only thick sorted out, these different mixed plastics can only make ordinary regeneration plastic products, the economic worth and then utilized is not high. If divide the plastics of different materials out again, the value of retrieving the plastics can rise by 5 times. For example PET plastic bottle can be used for producing the chemical fibre clothes.
It is reported Xiao large-scale to abolish, sort, stand transfer post go on, classify to 1500 ton about rubbish every day on average while being firm base Wu, deal with 2300 tons of rubbish every day when being the highest. Wang HongZhe thinks, let citizens carry on the detailed classification to the rubbish of one's own family, and classify the plastic articles of different materials to render to different garbage bins unrealistically. Deal with the industrialized automatic classification to the rubbish, it is a main route to solve rubbish classification.
Burn the rubbish Residents worry about pollution
At present, there is landfill on main handling of the rubbish or burn in Beijing. Wang Weiping says, the rubbish landfill of this city takes up 33.333 hectares of land every year. Comparatively speaking, the advantage burnt is very obvious: Save the land, is well below the air pollution to pile up various produced to pollute.
However, the perimeter residents in the place understand that the rubbish is burnt and does not burn and select site for the rubbish, two mouthfuls of evil Great Britain pollute, it is the question that residents care about most. Wang Weiping says: "By the look of technology, Great Britain's discharge standard of two mouthfuls of evil regarding the rubbish burns the factory, Japan is that 1 is received gram, Europe is that 0.1 is received gram. That is to say, a piece of rubbish burns two mouthfuls of content of evil Great Britain in per cubic meter of gas that the factory discharges only 0.1 is received gram. 0.1 receive gram what concept it is, in other words half the intersection of mutton and a bunch of evil Great Britain 2 times of producing that people take usually. This kind of emission is very small to peripheral residents' influence, it is safe to discharge, can not be carcinogenic. 25 of rubbish burn the factory in Tokyo of Japan, all build in the urban area, the capital rubbish in Austria is too built in the urban area to burns the factory. "
Some residents object to building rubbish and burning the factory, is afraid one's own real estate devalues, this has something to do with two mouthfuls of terrific psychology of evil Great Britain with people in the society. Wang Weiping says: "Garbage disposal can not be absolutely free from contamination, but existing technology can control two pollution problems that evil Great Britain brings in certain range, can not be carcinogenic within this range, and the rubbish of construction has certain safe distances to burn the factories and residential quarters.
