Abstract

The domestic refuse treatment process mainly includes: 1. sorting; 2. feeding refuse into conveying machine and separating out utilzible waste paper and waste plastics; 3. separating out metal wastes by using electromagnetic equipment; 4. feeding refuse into classifier in size; 5. making the fermented organic refuse undergo the process of drying, sterilizing, constant temp. cooling, grinding by means of grinding machine, forming organic fertilizer, packaging and selling; and 6. making another portion of refuse undergo the processes of grinding, mixing with clay to make hollow brick. Said invention is simple in technological process, does not produce secondary pollution and is favorable for environment protection.

Description

A kind of domestic rubbish disposal technology of samll cities and towns

Technical field

The present invention relates to garbage treating process, mainly is a kind of domestic rubbish disposal technology of samll cities and towns.Daily handling ability is at 30T, 50T, 80T, 100T, and 120-150T etc. are a series of.

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 house 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 garbage disposal of samll cities and towns is simple landfill disposal at present, and metropolitan domestic rubbish disposal need be invested 8-10 hundred million RMB and be built refuse-burning plant, just can reach the harmless treatment requirement; Many small town living garbage disposal 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.

Summary of the invention

Technical problem to be solved by this invention provides a kind of domestic rubbish disposal technology of investing little and effective samll cities and towns.

The technical solution adopted for the present invention to solve the technical problems.The domestic rubbish disposal technology of this samll cities and towns mainly comprises the steps: 1), go-no-go; 2), rubbish enters conveyer, earlier utilizable waste paper with give up to mould and clean out; 3), scrap metal pieces is separated by calutron; 4), rubbish enters the classifier of classifying with size, after the rubbish below 15 millimeters is separated, directly enter in the fermentation tube and carry out fermentation process; 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; 5), the organic waste after the fermentation is dried sterilization processing, then constant temperature cooling is ground with grinder then, and fineness is carried out moulding, the packing and selling of organic fertilizer at last between the 30-80 order; 6), another part grinds with grinder 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, thus protection land resource.

The technical solution adopted for the present invention to solve the technical problems can also be further perfect.Described fermentation process adopts weight fermentation, fermentation time five-seven days.Described oven dry is handled and is heated by biogas or fire coal, adopts dryer to dry, and temperature is between the 300-600 degree.

1), investment is little the effect that the present invention is useful is:, found the factory flexibly: equipment investment generally between 800,000-1,300,000, can be selected for use arbitrarily for big samll cities and towns.2), economize the land resource the regeneration materials for wall: in the garbage disposal process, have 40% raw material to can be used for producing light wall material, both for country economizes the land resource, the while brings economic benefit again in materials for wall production.3), twice laid, reclaiming: the refuse waste product is a lot of in the rubbish, as paper, plastics, metal, glass, copper, aluminium etc., can recycling, save national resources.4), prevent to pollute, help the protection of ecological environment.This technology is simple, does not burn and does not have sewage, can not produce secondary pollution, helps environmental protection.

The specific embodiment

Below in conjunction with embodiment the present invention is further described.The garbage treating process of this samll cities and towns mainly comprises the steps: 1), go-no-go; General house refuse is more assorted, various foreign material have, and therefore carry out simple artificial go-no-go before processing, such as the big stone of diameter, the vial of monoblock, waddy are directly separated, the foreign material that may rot all separation enter methane-generating pit, energy savings.2), rubbish enters conveyer, earlier utilizable waste paper with give up to mould and clean out; 3), scrap metal pieces is separated by calutron; 4), rubbish enters the classifier of classifying with size, after the rubbish below 15 millimeters is separated, directly enters in the fermentation tube and carries out fermentation process, fermentation process adopts weight fermentation, fermentation time five-seven days; The 15-50 millimeter separated and the rubbish of 50-100 millimeter are carried out break process, be used to make novel wall material; Wherein the rubbish of 15-50 millimeter belongs to fritter stone, and useless brick etc. divide in the course of conveying to pick refuse battery, aluminium alloy, copper, lead, aluminium block etc.To reclaiming after the refuse classification more than 100 millimeters of separating; 5), the organic waste after the fermentation is dried processing, moisture content is no more than 8%, and then constant temperature cooling is ground with grinder then, and fineness is carried out moulding, the packing and selling of organic fertilizer at last between the 30-80 order; 6), another part grinds with grinder through the rubbish of break process, fineness is mixed the clay of 30%-50% then between the 20-50 order, be used to make hollow brick.Above-mentioned oven dry is handled and is heated by biogas or fire coal, adopts dryer to dry, and temperature is between the 300-600 degree.Generally can replace with biogas at 5-11 month fuel, because interior fermentable rotten material of rubbish is more during this, the raw material abundance of biogas can be economized on coal half a year like this.

Claims

1, a kind of domestic rubbish disposal technology of samll cities and towns is characterized in that: mainly comprise the steps: 1), go-no-go; 2), rubbish enters conveyer, earlier utilizable waste paper with give up to mould and clean out; 3), scrap metal pieces is separated by calutron; 4), rubbish enters the classifier of classifying with size, after the rubbish below 15 millimeters is separated, directly enter in the fermentation tube and carry out fermentation process; 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; 5), the organic waste after the fermentation is dried sterilization processing, then constant temperature cooling is ground with grinder then, and fineness is carried out moulding, the packing and selling of organic fertilizer at last between the 30-80 order; 6), another part grinds with grinder 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.
