Composting method for treating garden wastes

Abstract

The invention provides a composting method for treating garden wastes, comprising the following steps of: S1, collecting garden wastes, sorting the garden wastes into branch wastes and grass leaf wastes, and respectively pulverizing; S2, adding decomposed substances into the grass leaf wastes, uniformly mixing, standing for 6-12h, adding water into the crushed branch wastes, then adding the treated branch wastes into the treated grass leaf wastes, uniformly mixing, and standing for 12-24h; S3, adding urea and strains into the mixed material obtained in the step S2, controlling the carbon-nitrogen ratio in the mixed material to 20-40: 1, the moisture content to 55-65% and the pH value to 5.5-8.5; and S4, stacking the mixed material obtained in the step S3 to a ventilated place for fermentation, turning the pile once every two days, and composting for 30-45 days. The composting method disclosed by the invention has the characteristics of simplicity and easiness in operation and is suitable for wide application.

Description

technical field [0001] The invention belongs to the technical field of composting, and in particular relates to a composting method for treating garden waste. Background technique [0002] With the acceleration of urbanization and the increase of the area of ​​urban garden green space, the amount of garden waste is also increasing. Garden waste is also called landscaping waste, greening waste, garden organic waste, garden waste and greening. Garbage, etc. Garden waste mainly refers to the plant residues produced by the natural fall of garden plants or artificial pruning, mainly including branches, leaves, grass clippings, etc. Garden waste is often treated by traditional landfill, incineration, etc. However, disposal methods such as landfill and incineration have problems such as wasting resources, occupying land, and producing secondary pollution. Therefore, composting of garden waste is considered to be the most effective and environmentally friendly disposal method. Becau...

Problems solved by technology

[0002] With the acceleration of the urbanization process and the increase of the area of ​​urban garden green space, the amount of garden waste is also increasing. Garden waste is also called landscaping waste, greening waste, garden organic waste, garden waste and greening. Garbage, etc. Garden waste mainly refers to the plant residues produced by the natural fall of garden plants or artificial pruning, mainly including branches, leaves, grass clippings, etc. Garden waste is often disposed of by traditional landfill, incineration, etc. However, disposal methods such as landfill and incineration have problems such as wasting resources, occupying land, and producing secondary pollution. Therefore, composting of garden waste is considered to be the most effective and environmentally friendly disposal method. Because the main components of garden waste are branches, Leaves, grass clippings, etc., lead to its main components being difficult to degrade cellulose, hemicellulose and lignin, etc., which makes the composting time of garden wastes long, low in efficiency and unsatisfactory in effect
