Description
Technical field
The invention belongs to field of environment protection, are related to a kind of waste disposal method, and in particular to a kind of engineering plastics rubbish
Processing method.
Background technique
With the development of China's plastics industry and the raising of the level of consumption, application of the plastic products in China is raw from industrial or agricultural
It is ubiquitous to produce clothing, food, lodging and transportion -- basic necessities of life, plastic refuse also attacks to us therewith.According to analysis of statistical data, extrapolate 2005
Plastics in China real consumption amount is 2 658.9 ten thousand t, and waste plastic yield is about 960.8 ten thousand t, and emission index about 36% accounts for China
15% or so of garbage emission total amount.Since nearly all plastics are all made of non-renewable petroleum, main component is hydrocarbonization
Object is closed, it can be with
Burning, it is the very high macromolecular material of calorific value that the heat ratio fuel oil such as polystyrene burns is also high, is had resistance to
The characteristic that sour, alkaline-resisting, weather-resistant etc. are corrosion-resistant, are not easily decomposed, causing can not be by natural decomposition, especially disposable modeling
Material packaging waste, plastics farm-oriented mulch arbitrarily abandoned by people and caused by visual pollution, i.e., it is so-called " white pollution ", and
Waste plastics potential hazard caused by environment has caused the common concern of relevant government department and society.The growth of plastic products
Speed is than other materials
Material is fast, and plastics are lower than the reuse ratio of metal or paper;The pass of correct treatment of waste plastics resource utilization and environment
System is rationally an urgent demand of China's economy, social sustainable development proposition using natural resources.China's main life at present
Technology of garbage disposal are as follows: Sanitary Landfill Technology, power generation by waste combustion technology, comprehensive treatment technique (composting technology).Waste plastics is in rubbish
In sanitary landfills processing not only many negative potential danger cannot will be also brought by resource utilization, and by facts have proved
Evil.Since plastics package is in the majority in waste plastics, their density are small, volume is big, and place can be filled up quickly by being not easily decomposed, and reduce landfill
The ability of place processing rubbish;And the place after landfill due to ground it is soft, the harmful substances such as bacterium, virus in rubbish
It is easily penetrated into underground, polluted underground water jeopardizes ambient enviroment.The characteristic of plastics, it is resolved that its final disposal should not fill.
And garbage loading embeading is using rubbish as waste processing, the utilization rate to waste resources is zero, does not meet national sustainable development
Principle is not the ideal method of garbage disposal.Engineering plastics can make the modeling of engineering material and replacement metal manufacture element part etc.
Material.Engineering plastics have excellent comprehensive performance, and rigidity is big, and creep is small, high mechanical strength, and heat-resist, electrical insulating property is good, can
It is used for a long time in harsher chemistry, physical environment, alternative metal is used as structural timber, due to engineering plastics
Intensity it is larger, deal with it is more difficult, therefore be badly in need of it is a kind of it is scientific and reasonable, environmental pollution is small, can be utmostly
Using abandoned project plastics be worth approach.
Summary of the invention
To solve the above-mentioned problems, the present invention is directed to the characteristics of engineering plastics, proposes a kind of scientific and reasonable, dirty to environment
Contaminate method that is small, being worth to the greatest extent using abandoned project plastics.
The present invention is achieved by the following technical solutions.
