Embodiment 1

[0023] An embodiment of an environment-friendly landscaping waste composting treatment method of the present invention: an environment-friendly landscaping waste composting treatment method, comprising the following steps:

[0024] Step 1, landscaping waste is pulverized;

[0025] Step 2, measuring the initial total carbon content and total nitrogen content of the green waste after crushing, calculating the initial C / N ratio, adding nitrogen to the green waste to make the C / N ratio 25:1;

[0026] Step 3, stacking the greening waste, keeping the water content above 65%, and adding fermentation strains, cellulase, composting fermentation bacteria and microbial surfactants;

[0027] Step 4, turn over and ferment to complete the compost preparation.

[0028] The nitrogen source is indispensable for the growth and development of microorganisms. The role of nitrogen is to synthesize key components (such as amino acids, proteins, purines, pyrimidines, nucleic acids, etc.) in microbi...

Embodiment 2

[0030] An embodiment of an environment-friendly landscaping waste composting treatment method of the present invention: an environment-friendly landscaping waste composting treatment method, comprising the following steps:

[0031] Step 1, the landscaping waste is crushed, and the crushed particle size is below 3cm, preferably 2×3×0.8cm (length×width×thickness) particle size;

[0032] Step 2, measuring the initial total carbon content and total nitrogen content of the green waste after crushing, calculating the initial C / N ratio, adding nitrogen to the green waste to make the C / N ratio 25:1;

[0033] Step 3, stacking the greening waste, keeping the water content above 65%, and adding fermentation strains, cellulase, composting fermentation bacteria and microbial surfactants;

[0034] Step 4, turn over and ferment to complete the compost preparation.

Embodiment 3

[0036] In this embodiment, the determination of the initial total carbon content and total nitrogen content is performed by a CNOS elemental analyzer.

Abstract

The invention relates to the field of greening waste recycling, in particular to an environmentally friendly garden greening waste composting treatment method. The method comprises the following stepsthat 1, garden greening waste is crushed; 2, initial total carbon content and total nitrogen content of the greening waste obtained after crushing are measured, an initial C / N specific value is worked out, nitrogen is added in the greening waste, and the C / N specific value is 25:1; 3, the greening waste is stacked, the water content is kept at 65% or above, and fermentation strains, cellulase, compost fermentation bacteria and microbial surfactant are added; 4, turning and fermentation are conducted, and compost fermentation is completed. Accordingly, by means of microorganism species selection and environmental condition improvement, the microbial activity is promoted, improvement is conducted on the basis of an original treatment mode, and finally a rapid and pollution-free environmentally friendly greening waste treatment mode is achieved.

Description

technical field [0001] The invention relates to the field of greening waste reuse, in particular to an environment-friendly method for composting landscaping waste. Background technique [0002] Landscaping waste generally refers to wooden waste such as greening buildings, fallen leaves, dead branches, and grass clippings generated during urban greening maintenance. For the treatment of green waste, the traditional methods include landfill, random discard and illegal incineration. Although this kind of treatment can reduce the amount of green waste, it will cause serious air pollution, groundwater pollution and soil resource encroachment. Environmental issues. From the perspective of resources, landscaping waste is a kind of biomass material, which can be reused as a raw material that can participate in production in the future. Composting technology treats landscaping waste, which greatly reduces the air pollution caused by incineration, and also saves land resources oc...
