Problems solved by technology

[0004] In view of the above problems, the present invention provides a circular treatment method suitable for landscaping organic solid waste, which distinguishes and disposes landscaping waste through a special crushing and screening process, and constructs a dual-line treatment of organic mulch and composting products capacity system to solve the problems of single product, long fermentation cycle, and high processing cost brought about by the single composting of landscaping waste, as well as the high lignin and cellulose content in landscaping waste, which leads to waste Insufficient fermentation of materials, low degree of humification, low product quality due to high organic carbon content, and soil fertility decline caused by application of soil

Embodiment 1

[0026] A recycling method suitable for landscaping organic solid wastes, comprising the following steps:

[0027] (1) Collect landscaping waste, including 2000kg of thick branches, 1500kg of branch and leaf trimmings, 500kg of lawn trimmings, and 200kg of plant residues, and grab the landscaping waste with a wooden clamp and enter the crushing equipment. The equipment adopts the crawler produced by the American MORBARK company The horizontal crusher adopts a unique pressure roller hammer grinding process, so that the thick branches are evenly hammered to form a wire-like medium-sized waste, and the remaining branches and leaves, lawn trimmings, and plant residual flowers are hammered and crushed , to form small-sized waste with uniform texture; the crushed mixed product is transported by the loader, and enters the mobile roller screen PRONAR with circular apertures of 1cm and 3cm respectively, and the small-sized waste and the medium-sized waste After sieving, the length of th...

Embodiment 2

[0035] A recycling method suitable for landscaping organic solid wastes, comprising the following steps:

[0036] (1) Collect landscaping waste, including 1500kg of thick branches, 1000kg of branch and leaf trimmings, 800kg of lawn trimmings, 150kg of plant residual flowers, and 50kg of seeds. The green waste is grabbed by a wooden clamp and entered into the hammer mill crushing equipment produced by MORBARK in the United States. Using unique pressure roller hammer grinding process, the particle size can be basically controlled within 10cm after a crushing through a customized screen. The pressure roller welded with wear-resistant and pressure-resistant material teeth and horizontal knives can be lifted and rotated freely through hydraulic power, thick branches After being evenly hammered and milled, it will form a wire-like wood fiber, and the remaining branch and leaf trimmings, lawn trimmings, and plant residual flowers will be hammered and pulverized to form small-sized was...

Abstract

The invention belongs to the technical field of organic solid waste treatment, and particularly relates to a circular treatment method suitable for landscaping organic solid waste. According to the method, landscaping waste is subjected to smashing, hammer milling and multi-stage linkage screening to obtain medium-particle-size waste and small-particle-size waste; the medium-particle-size waste forms a colored organic mulch product through treatment means such as stacking, decomposing, fermenting, dyeing and drying; the small-particle-size waste is subjected to composting treatment in a unified mode, and a compost product with high quality is obtained through a process combining two times of fermentation, and can be directly used for soil improvement and production of a green nutrient medium. Crushed landscaping waste is classified, reasonable disposal modes are selected according to different materials, complementary advantages are formed among multiple processes, multiple resource utilization products are prepared, and meanwhile, complete dust prevention, wastewater treatment and other processes are combined, so that secondary pollution is avoided while the landscaping waste is fully recycled.

Description

technical field [0001] The invention belongs to the technical field of organic solid waste treatment, and in particular relates to a recycling treatment method suitable for landscaping organic solid waste. Background technique [0002] In recent years, with the continuous expansion of urban landscaping area, the amount of landscaping waste is also rising, which brings great pressure to the urban environment. Originally, these garden wastes were often regarded as solid wastes, and the usual way of disposal was landfill or incineration, among which landfill would occupy valuable land resources, increase the cost of government waste disposal, and also cause waste of biomass resources; In addition, the moisture content of urban green waste as wet garbage is generally high, making it very difficult for waste incineration plants to mechanically sort garbage and other pretreatments. At the same time, high moisture content will also reduce the calorific value of garbage, and the inc...
