Description
Technical field
The present invention relates to a kind of method and the device that utilize garden waste production organic mat.
Background technology
Earth surface of garden trees is a kind of new city greening earth's surface covering material, by covering the organic substance on forest earth's surface in simulating natural environment, to reach the object strengthening urban ecological function, have and improve soil ecology, keep soil moisture, increase soil fertility, suppress weed growth, absorption airborne dust, promotes arboreal growth, and the function such as to beautify the environment.
Earth surface of garden trees common at present utilizes the byproduct of wood-processing industry or directly uses timber to be starting material, formed by physical pulverization and following process process.Because China's Forest Resources is relatively limited, the earth surface of garden trees production technology of this quasi-tradition is subject to the restriction of raw material supply and cost, and is not suitable for the current national conditions of China.In addition, due to without high temperature degradation process, this kind of organic mat in use easily introduces disease and pest, and the Humus composition that can be plant utilization provided is also very low.
As one of the important composition composition of domestic waste, garden waste in the resource utilization rate of European and American developed countries more than 50%.Compared with developed countries comparatively, the resource utilization rate of China's garden waste is very low, and overall average level is less than 5%.At present, the treatment process of China's city trees and shrubs waste is still based on landfill and burning, and because garden waste density is lower, relative to other municipal wastess, the garden waste of equal quality will consume larger landfill yard space, waste land resources.In addition, with stalk seemingly, it is also the main contributions source of city PM2.5 that garden waste is burned, and according to Ornamental Plants of Beijing District office statistics, open incineration fallen leaves reach 12.5% to the contribution rate of PM2.5.Along with the quick growth of China's city size and the continuous increase of urban green space area, the output of city trees and shrubs waste also rapidly increases in the past for 10 years, and exacerbates the burden of Municipal Domestic Waste Treatment Facility further.
While garden waste pollutes constantly obstruction urban development, also containing a large amount of available holophytic nutrition and bio-energy in garden waste.By the method for bio-transformation, these reproducible materials can be effectively transformed as available nutritive substance and energy, have very great meaning to solution environmental pollution and energy-saving and emission-reduction.In recent years, along with popularizing of ecological garden theory, European and American developed countries utilize the ratio of garden waste production earth surface of garden trees more and more higher, by earth surface of garden trees, garden waste is revert in the middle of nature, not only can reduce the impact of mankind's activity on physical environment, improve the quality of life of city resident, also can save the maintenance cost of a large amount of afforestation, be a kind of practical technique meeting the current national conditions of China simultaneously.
