Description
Technical field
The present invention relates to a kind of clean applications of the domestic garbage incineration flyash after water-washing pre-treatment in road surface, belong to solid
Body offal treatment disposal and recycling, road paving materials and its processing technology of preparing crossing domain.
Background technology
Domestic garbage incineration flyash is the trapping thing and flue and chimney bottom of municipal solid waste incinerator flue gas purification system
The bottom ash of sedimentation.Research shows, containing poisonous and harmful substances such as dioxin and heavy metals in domestic garbage incineration flyash, because
This, China is classified as《National Hazard waste register》In HW18 class hazardous wastes, it is improper conduct oneself well put and can directly threaten around
Environment and human health, and public group event can be triggered and then influence waste incineration industry actively to develop in a healthy way.House refuse
The toxicity of flying ash and the characteristic for easily causing secondary pollution are also important original that municipal solid waste incinerator addressing is queried by the public
Cause.
Now some developed countries mainly include for the disposal technology of domestic garbage incineration flyash at present：Mine is buried, height
Temperature melting, clinker mixing disposal etc., but in view of China's national situation, investment cost of disposal and current law limitation etc., the above
Technology is not suitable for China's use at present.And the main disposal options of domestic garbage incineration flyash of domestic current include：Directly enter
Enter hazardous waste landfill landfill, chelating agent stabilize or cement solidification after enter sanitary filling field landfill, at cement kiln collaboration
Put etc., there is processing cost height in these methods, be also easy to produce the secondary pollution of environment, and land occupation resource exists rotten to equipment
The shortcomings of erosion.
Based on above reason, development environment is friendly, meet the incineration of refuse flyash disposal technology of China's economic development, from root
Change flying dust disposal actuality in sheet, the contradiction between the current waste incineration industry energy, environment, resource three is broken through, in turning into
The Major Strategic Demand of state's waste incineration industry value chain.
The content of the invention
In view of this, it is an object of the invention to provide a kind of domestic garbage incineration flyash application by after water-washing pre-treatment
In the technical scheme of road surfacing, the technical scheme realizes recycling cleaning of the domestic garbage incineration flyash in road surface should
With.
The technical scheme that the present invention takes is as follows：
1st, clean applications of the water-washing pre-treatment domestic garbage incineration flyash in road surface, by the consumer waste incineration after washing
