Abstract

The pretreating process of garbage without stack yard includes the following steps: sorting; classifying in size; conveying to fermenting tank; and post-treatment. The post-treatment step incldues direct fermenting treatment of garbage below 15 mm in fermenting cylinder; crushing garbage over 15 mm size; sterilizing fermented organic garbage before cooling and grinding; forming organic fertilzier and packing; the present invention has the advantages of reduced used field, reduced environmental pollution caused by stacked garbage, reduced harmful matter entering to the organic fertilizer, and increased fermenting time and thus fertility of the organic fertilizer.

Description

A kind of pretreating process for garbage without stack yard

Technical field

The present invention relates to garbage treating process, mainly is a kind of pretreating process for garbage without stack yard

Background technology

Fast development and quickening of urbanization process along with economic society, the refuse production in China city constantly increases, average annual increasing degree surpasses about 10%, and the domestic refuse pollution problems becomes increasingly conspicuous, and has had a strong impact on the town environment sanitary condition and the people's quality of life.The refuse treatment of samll cities and towns is simple landfill disposal at present, and metropolitan domestic rubbish disposal need be invested 8-10 hundred million Renminbi and be built refuse-burning plant, just can reach the harmless treatment requirement; Many small town living refuse treatment standards are low, are simply equipped, and just make simple landfill, form new dirty source, cause the secondary pollution of domestic rubbish disposal.Do not reach innoxious, the requirement of minimizing and recycling treatment.And before landfill, rubbish all is air storage, has both taken to use the place, and the corrosive odor of generation produces surrounding enviroment and pollutes.

Summary of the invention

Technical problem to be solved by this invention provides a kind of pretreating process for garbage without stack yard of piling up the place, reducing environmental pollution that do not have.

The technical solution adopted for the present invention to solve the technical problems.This pretreating process for garbage without stack yard mainly comprises the steps: 1), the rubbish of transporting to directly carried out go-no-go handle; 2), rubbish enters the sorting machine processing of classifying by size; 3), be transported to the fermentor tank storage; 4), carry out postprocessing working procedures.

The technical solution adopted for the present invention to solve the technical problems can also be further perfect.Described go-no-go is handled: rubbish enters transfer roller, earlier utilizable waste paper and useless moulding is cleaned out; By calutron scrap metal pieces is separated.Described postprocessing working procedures: 1), after the rubbish below 15 millimeters separates, directly enter in the fermentation tube and carry out fermentative processing; The 15-50 millimeter separated and the rubbish of 50-100 millimeter are carried out break process, be used to make novel wall material; To reclaiming after the refuse classification more than 100 millimeters of separating; 2), the organic waste after the fermentation is dried germicidal treatment, then constant temperature cooling is ground with shredder then, and fineness is carried out moulding, the packing and selling of organic fertilizer at last between the 30-80 order; 3), another part grinds with shredder through the rubbish of break process, fineness is mixed the clay of 30%-50% then between the 20-50 order, be used to make novel wall materials such as hollow brick.Fermentative processing adopts weight fermentation, fermentation time five-seven days.

1), reduced the use place effect that the present invention is useful is:, reduced because dumping produces the pollution of corrosive odor to surrounding enviroment.2) significantly reduced because time of stacking garbage is longer, impelled as corrosion such as batteries and decompose, objectionable impurities is entered in the organic fertilizer, exempted to make the farmland to be subjected to secondary pollution.3) increased fermentation time, what guaranteed organic fertilizer has than property.

Embodiment

Below in conjunction with embodiment the present invention is further described.This pretreating process for garbage without stack yard mainly comprises the steps: 1), the rubbish of transporting to directly carried out go-no-go handle; Rubbish enters transfer roller, earlier utilizable waste paper with give up to mould etc. and clean out; By calutron scrap metal pieces is separated.2), rubbish enters the sorting machine processing of classifying by size; 3), be transported to the fermentor tank storage; 4), carry out postprocessing working procedures.A), after the rubbish below 15 millimeters separates, directly enter in the fermentation tube and carry out fermentative processing; The 15-50 millimeter separated and the rubbish of 50-100 millimeter are carried out break process, be used to make novel wall material; To reclaiming after the refuse classification more than 100 millimeters of separating; B), the organic waste after the fermentation is dried germicidal treatment, then constant temperature cooling is ground with shredder then, and fineness is carried out moulding, the packing and selling of organic fertilizer at last between the 30-80 order; C), another part grinds with shredder through the rubbish of break process, fineness is mixed the clay of 30%-50% then between the 20-50 order, be used to make novel wall materials such as hollow brick.Fermentative processing adopts weight fermentation, fermentation time five-seven days.
