Description
Technical field
The present invention relates to garbage disposal and regenerative use technology field, specifically a kind of life and construction refuse resource are followed
Ring utilizes technique.
Background technique
Current domestic rubbish disposal occupies large amount of land resources frequently with landfill or the method burned, and is formed serious
Pollution, endangers people's health, destroys the living environment of people, become the hot and difficult issue that people urgently solve and ask
Topic.
Building waste becomes as the maximum urban waste of discharge rate and solves environmental pollution, reduce disposal of pollutants rate, mention
The important topic of high resources rate of production.The current building waste in China is usually the building waste of brick mix structure, generally includes to glue
Native fired brick, concrete, mortar etc., and most of building wastes are unable to natural degradation, storage building waste needs to occupy
A large amount of land resource.
Each big and medium-sized cities in the whole nation are still that most house refuses and building waste are transported to city suburbs waste heap
Field is stacked, this is main or since house refuse and construction refuse resource lack high value added utilization technology.House refuse and
The recycling industry development of building waste will walk the road of ecological environment material nd, green construction material, walk high added value recycling
The road utilized.
Currently, the processing method of building waste predominantly manually sorts metal material, wood materials and plastic materials
Sort out, is supplied into corresponding company and is handled, then recycled aggregate will be made after construction waste crushing.Country also puts into effect
Relevant criterion, such as《Concrete regenerated coarse aggregate》（GB/T25177-2010),《Concrete and mortar recycled fine aggregate》
（GB/T25176-2010) and《Recycled aggregate application technology regulation》（JGJ/T240-2011）.
But the processing mode of existing building rubbish or house refuse is more single, shows single building waste resource
Change using either single domestic waste incineration residue resource utilization, building waste or house refuse can not be further increased
Comprehensive utilization ratio.
The resource recycling of house refuse and building waste recycling can not only protect environment, reduce the dirt to environment
Dye, and according to scientific management and effective measures by its minimizing and recycling, can also save a large amount of construction fund and
Resource.
House refuse and building waste comprehensively utilize, and the regeneration for the thermal energy building waste for generating house refuse mentions
Water supply and the energy, accomplish to comprehensively utilize, avoid secondary pollution, become urgent problem to be solved in industry.
