Abstract
The invention relates to a process and method for comprehensive utilization of garden wastes. The process and method comprise the following steps of firstly, classifying the garden wastes into two classes, namely branches of which the diameter is above 1.5cm as one class and branches of which the diameter is below 1.5cm, leaves and broken grass and flowers as the other class; then placing the two classes of garden wastes in a special charring kiln and charring, recycling the flue gas produced by charring via a special flue gas recycling device, and then carrying out a grooved-type composting fermentation on charcoal for charcoal-based fertilizers obtained by carbonizing branches of which the diameter is below 1.5cm, leaves and broken grass and flowers, stirring charcoal scraps and wood vinegar, mixing to obtain a vinegar-charcoal mixture, adding the vinegar-charcoal mixture into a fermentation reactor, sieving the fermented powder, continuously fermenting residual coarse particles, sieving to obtain powder and directly bagging to obtain the organic fertilizer. The process and method for comprehensive utilization of garden wastes disclosed by the invention achieve the full resource utilization of increasingly growing garden wastes in major cities and have the advantages of zero emission in production, good economic returns and enormous social benefits.
Description
Technical field
The present invention relates to biomass comprehensive and utilize field, relate in particular to a kind of processing method of garden garbage comprehensive utilization.
Background technology
Constantly increase at current city's green areas, under garden garbage background of piling up in enormous quantities, urban landscaping rubbish becomes the problem of each big city headache, particularly in long-term areas of high temperature and rainfall, flowers, plants and trees increment is large, and Landed Typhoon gardens increase severely quantity of refuse in addition.At present national each big city processing afforestation rubbish mainly uses the method for landfill and burning, adopt the method land seizure amount of landfill large, can not resource recycling utilization, the method for burning increases a large amount of flue gases and charcoal discharge, increase haze, forbidden by most of city.Some cities start to attempt adopting the method recycling of fermented manure, but comprehensive utilization charcoal processing, off-gas recovery processing and the polytechnic city of compost fermentation also do not have.Increasingly serious at current environment pressure, resource is day by day deficient, and under the day by day serious background of global greenhouse effect, the invention application of this technology, has great social benefit.
Summary of the invention
Object solved by the invention is to provide a kind of processing method of garden garbage comprehensive utilization, to solve the problem existing in background technology.
