Abstract
Production of organic fertilizer by urban refuse is carried out by crushing, separating, recovering reused substances from urban refuse, sterilizing by caustic lime, crushing for separated refuse, fermenting, adding into mud, baking accessories and urea and carbon ammonia, inducing while heating for 2-5 days to obtain organics and organic salts, delivering fermented refuse into drying kiln, drying, grinding dried refuse to 200 meshes, screening and packing to obtain powdery fertilizer. It's efficient, cheap, has various raw materials and no environmental pollution and can be reutilized.
Description
Technical field:
The present invention relates to refuse reclamation, particularly municipal wastes recycling.
Background technology:
At present the quantity of refuse of city every day is huge especially, complicated component, remove plastic waste material, scrap metal pieces, outside the rubber waste product etc., remaining most of waste contains abundant organic matter, inanimate matter and mineral substance, the processing of rubbish is an important problem, adopt air storage and landfill, floor space is big, and causes ground and groundwater pollution, and more is to adopt burning method, but contain chlorine in the flue gas that burns, objectionable constituent such as fluorine gas and sulfurous gas, atmosphere pollution also has harmful substances in the rubbish ash after the burning, and rubbish ash amount is also very big, can not find suitable purposes and take the farmland in a large number, secondary pollution is serious.
Summary of the invention:
The objective of the invention is to overcome above-mentioned not enough problem, it is the method for raw material production fertilizer that a kind of municipal wastes is provided, and technology is simple, and raw material is extensive, and cost is low, fertilizer efficiency height and environmental protection.
The technical scheme that the present invention is adopted for achieving the above object is: municipal wastes is the method for raw material production fertilizer,
The first step, pulverizing: sorting, reclaim renewable, the material that utilizes in the municipal wastes, as scrap metal, plastics, glass, slowly porcelain, cloth, brick, watt, sand, stone etc., to the rubbish after the sorting with lime water sterilization, sterilization back coarse reduction.
Second step, fermentation: the rubbish after the pulverizing is sent into artificial fermentation's device, adds mud, fermentation assistant and urea or carbon ammonium, and heating was brought out 2-5 days, just can become thoroughly decomposed, and contained nutritive ingredients such as suitable organic matter, organic salt in the rubbish that becomes thoroughly decomposed;
The 3rd step, grinding: the rubbish after the fermentation is sent to the oven dry kiln dry, and the rubbish to oven dry is ground to 200 orders then, and the screening packing can make powdered fertilizer.
It is 1-5: 100-200 that described fermentation adds urea or carbon ammonium and rubbish weight part ratio.
Fermentation assistant is vinasse, livestock or poultry manure etc. in described second step.
The fuel used employing of oven dry is reclaimed biogas or rubbish digest process and is overflowed gases such as biogas and ammonia, sulfide and act as a fuel in described the 3rd step.
The present invention makes on the basis of fertilizer at traditional utilize rubbish, plant, ight soil etc., in conjunction with the regeneration production composite fertilizer of municipal wastes, and fully can be with the phosphate fertilizer of municipal wastes conversion processing for needing for crop growth.Compare with existing like product and to have outstanding feature: rubbish sterilization, harmless treatment, kept original nutritive element in the rubbish, improved fertilizer efficiency after adding urea or carbon ammonium, effectively improve the soil, satisfy the needs of farm crop to nitrogenous fertilizer, improve harvest.Production method of the present invention is reasonable, technology is simple, the comprehensive utilization ratio height of rubbish, and cost of investment is little, and raw material sources are extensive, and product cost is low, turns waste into wealth, with the effective environmental resource regeneration, economic benefit, environmental benefit and obvious social benefit.
Embodiment:
The present invention is described in further detail below in conjunction with embodiment:
Embodiment 1
The first step, pulverizing: sorting, reclaim renewable, the material that utilizes in the municipal wastes, as scrap metal, plastics, glass, slowly porcelain, cloth, brick, watt, sand, stone etc., to the rubbish after the sorting with lime water sterilization, sterilization back coarse reduction.
Second step, fermentation: the rubbish after 100 tons of pulverizing is sent into artificial fermentation's device, add fermentation assistant and 1 ton of urea such as mud, vinasse, livestock or poultry manure, heat 130 ℃ and brought out 2-5 days, just can become thoroughly decomposed, contain nutritive ingredients such as suitable organic matter, organic salt in the rubbish that becomes thoroughly decomposed;
The 3rd step, grinding: the rubbish after the fermentation is sent to the oven dry kiln dry, and the rubbish to oven dry is ground to 200 orders then, and the screening packing can make powdered fertilizer.
Embodiment 2
Is the raw material production fertilizer according to embodiment 1 described method with the municipal wastes, adds 3 tons of carbon ammoniums in 100 tons of rubbish during fermentation.The fuel used employing of oven dry is reclaimed biogas or rubbish digest process and is overflowed gases such as biogas and ammonia, sulfide and act as a fuel in the 3rd step.Other and embodiment 1 are identical.
