Description

It is a kind of that compost treatment technique is carried out to rubbish

Technical field

The present invention relates to a kind of technique, and compost treatment technique is carried out to rubbish more particularly, to a kind of.

Background technology

Rubbish refer to need not or useless solid, flowing material.In densely populated big city, garbage disposal is an order The problem of people has a headache.Common way is to be sent to landfill after collecting, or is incinerated with incinerator.But both of which can manufacturing environment The problem of protection, and landfill degree of saturation can further be mitigated by terminating overconsumption.The improper meeting of garbage disposal in landfill Polluted underground water and stink, and many cities are available for the area of landfill fewer and fewer.Incineration is then unavoidable to produce Raw toxic gas, endangers organism.Method caused by rubbish is all reduced in most cities in research, and encourages resource reclaim.Build Building refuse is not real rubbish, is slightly handled, and with regard to that can turn waste into wealth, typically can use following two method to building waste Handled.Caused building waste in demolition of buildings, house decoration and transformation road is transported into Treatment stations with car first Institute, then, method manually by building waste can the material that utilizes of Direct Regeneration, such as metal material, wooden class material With plastic materials sorting and grouping, directly feed corresponding company and handled.To the bulk waste concrete in building waste, give up The materials such as brick, marble, the size that can be crushed to pulverizer using large-scale broken hammer or crusher in crushing, typically less than 100 Millimeter, then with the stone needed for stone crusher be crushed to building, sand, then by said mixture multi-layer grading sieve It is classified into rubble for closing symbol building standard, microlith, coarse sand, fine sand, and the regrown material such as silt particle.Industrial water is adopted With activated carbon counter-infiltration purifying domestic sewage and recycle, not only using water wisely but also can prevent the exhaust emission ring again of sewage Border.Lower mask body from it is following some tell about how building waste recycles.First, using discarded building concrete and discard Masonry produces coarse-fine aggregate, available for the concrete of production respective strengths grade, mortar or prepares such as building block, wallboard, floor tile Deng building material.After coarse-fine aggregate addition solidification class material, it can also be used to highway road surface.Second, produce bone using useless brick and tile Material, available for building materials such as production regeneration brick, building block, wallboard, floor tiles.Third, dregs can be used for road construction, pile foundation filler, Foundation etc..Fourth, for waste wood class building waste, the timber not yet substantially destroyed can be reused directly for reconstruction and build Build, the Wood member of badly broken can be as the raw material of wooden regenerated plates or papermaking etc..Fifth, discarded pavement asphalt mixing Material can be directly used in Recycled Asphalt Pavement by proper proportion.It is used to match somebody with somebody sixth, unmade road concrete can be processed into regeneration aggregate Preparation, regeneration concrete.Seventh, scrap steel, steel scrap muscle and other old metal materials can directly recycle or melt down processing.
