The invention discloses a kind of igelite waste disposal method, including the four-stage handled in fluid bed, and in the first stage with adsorbent is used in combination in second stage.Compared with prior art, fluidization is used in combination in waste disposal method of the present invention and adsorption technology handles igelite, the advantages of having treatment effeciency high, secondary pollution is avoided to generate.
Description
Technical field
The invention belongs to field of environment protection, are related to a kind of waste disposal method, and in particular to reference to fluid bed and absorption
Method to the method for igelite garbage disposal.
Background technology
Plastic products have that light, waterproof, durable, production technology is ripe, at low cost etc. excellent as a kind of new material
Point.With the rapid development of petrochemical industry and Plastics Processing Industry, plastics and its product enter daily life in large quantities.1992
China's plastics consumption figure is 5,700,000 t, nineteen ninety-five whole nation plastic products consumption figure up to 11,000,000 t, 1996 oneself up to 12,000,000 t with
On, Year's consumption also increases with annual 14% speed.Present China is one of ten big plastic products producing country of the world, simultaneously
It is the consumer nation of the big plastic material of the first in the world again.With greatly improving for plastic products consumption, discarded in municipal refuse
Plastic products amount also linearly rise.It is particularly in coastal cities in the domestic waste in China, plastic quality content
Up to 8~15%, percent by volume reaches the level of industrially developed country's municipal garbage, and also increase in high speed up to more than 30%
It is long.
The needs of growing urbanization can not be met due to the collection of China's municipal refuse, in disposal facility short-term,
A large amount of waste plastics is caused to be lost in rubbish to enter in environment, in road both sides, everywhere may be used on branch, in thick grass and on the water surface
See, seriously affect the city appearance of the city and tourist sight, cause environment " white pollution ".Plastics package waste to the harm of environment not only
The pollution of visual aspects is generated, but also the harm of bigger can be brought to industrial and agricultural production.The waste plastics swum on the water surface can
The decline of hidden danger and productivity is brought with the safe operation to communications and transportation, hydroelectric facilities；Waste plastics abandons in the soil
When reaching a certain amount of, the underproduction of crops can be caused；When by garbage loading embeading, due to long-term difficult to degrade, the meeting of waste plastics
A large amount of soils are occupied, land resource can not be recycled；The waste plastic product being discarded in land or water body is also possible to animal
It constitutes a threat to, is swallowed by animal as food, lead to animal dead etc..
In municipal refuse, plastics can be divided into two major class of thermoplastic waste plastic and thermosetting property waste plastics by its property.Thermoplastic
Property plastics all there is the property of heated after-tack, such as polyethylene（PE）, polypropylene（PP）, polystyrene（PS）And polyvinyl chloride
（PVC）.Another kind of, thermosetting plastics will not soften when heated, such as phenolic resin, melamine resin, poly- amino first
Sour second fat.Mainly with polyethylene in discarded plastics（PE）And polyvinyl chloride（PVC）Based on, wherein PVC accounts for about 10~20%
Left and right.PVC calorific values in domestic waste are very high（About 22000kJ/kg）, content is very big, while in processing procedure
Also it is easiest to generate the ingredient of secondary pollution, is either burning or a large amount of HCl gas can be all generated in gasification
Body, Cl elements still form dioxin（PCDD and PCDF）One of the chief elements.
In the prior art, the method used to the garbage disposal containing polyvinyl chloride is mostly burning method, in burning process
Secondary pollution, predominantly CO gas and hydrogen chloride gas are also easy to produce, the two can all generate human body and environment can not
The harm of recovery.
Invention content
Present invention solves the technical problem that it is：The defects of in order to overcome the prior art, acquisition one kind, which can be effectively treated, to be contained
