Problems solved by technology

[0004] However, due to incomplete fermentation during the fermentation process of the stockpiles, malodorous substances will be produced, which will pollute the production environment and affect the air around the production plant and the living environment. Intermittently spray water to the pile, and the malodorous substances flow out together with the seepage from the fermentation of the pile. In the existing process, the seepage is collected and recycled as spray water, resulting in the leakage of seepage and spray water. Odor substances are constantly enriched, and the production environment is getting worse

Embodiment 1

[0036] A kind of garden waste composting technology, it comprises the following steps:

[0037] S1: Prepare raw materials in parts by mass, 75 parts of garden waste, 10 parts of chicken manure, 8 parts of synergist, and 0.5 part of decomposing agent. Effect agent" and decomposing agent are commercially available products of Beijing Jiabowen Biotechnology Co., Ltd. "organic material decomposing agent";

[0038] S2: Mix the garden waste, chicken manure, synergist, and decomposing agent weighed in S1 evenly to obtain a mixture, stack the mixture in a pile with a ground diameter of 2m and a height of 1.5m, and spray from top to bottom Sprinkle with water to adjust the moisture content in the mixture to 50-60wt%;

[0039] S3: The mixture is stacked and left still, and the water content of the mixture is detected every 30 minutes. The moisture content is less than 50wt%, and the water is sprayed on the pile to replenish water until the mixture reaches 50-60wt%;

[0040] S4: During...

Embodiment 2

[0045] A kind of composting process of garden waste, based on the basis of embodiment 1, per cubic meter of seepage liquid is matched with 65kg green sticks for production.

Embodiment 3

[0047] A kind of composting process of garden waste, based on the basis of embodiment 1, every cubic meter of seepage liquid is matched with 75kg green sticks for production.

Abstract

The invention relates to the technical field of garden waste recycling, and discloses a garden waste composting process. The garden waste composting process overcomes the problem that malodorous substances generated during fermentation in an existing composting process influence a production environment and the surrounding environment of a factory is solved. According to the garden waste composting process, after leachate is collected, green branch materials are mixed with and soaked in the leachate, and colloid leached from the green branch materials is utilized to adsorb and condense malodorous substances and heavy metal ions in the leachate and separate the malodorous substances and the heavy metal ions from the leachate in a precipitation manner, so the concentration of the malodoroussubstances in the leachate is reduced, the concentration of malodorous substances in ambient air of a regeneration tank is reduced, the accumulative malodorous substances in the leachate are continuously removed in the subsequent circulation of leachate-regeneration liquid-leachate, and the influence of malodorous substances produced in fermentation and composting on the environment is reduced. The invention also discloses a composting process taking the used green branch materials as a raw material, so cyclic utilization is realized, fermentation and composting degrees are improved, and a composting product with few viruses and pathogenic bacteria is obtained.

Description

technical field [0001] The invention relates to the technical field of garden waste recycling, in particular to a garden waste composting process and a composting product prepared therefrom. Background technique [0002] Garden waste will be generated during the maintenance process of landscaping. Garden waste includes tree and shrub pruning (thinning), lawn pruning, fallen leaves, branches, discarded grass and flowers in gardens and flower beds and Vegetable material such as weeds. In recent years, landscaping waste has been increasing, and the processing work has become increasingly severe. Only by studying efficient landscaping waste disposal strategies can the landscaping work serve the improvement of the local environment. [0003] At present, the more popular garden waste treatment method is composting garden waste, using microorganisms to degrade it into organic matter, and after fermentation, the organic perishable matter in the raw materials is transformed into org...
