Problems solved by technology

[0003] However, these plant wastes have the advantages of high nutrient content and low heavy metal content, and have huge reuse value such as composting. Stacking without recycling is a serious waste of resources.
In addition, the soil of the newly-built road green belt is mostly raw soil, mixed with construction waste, the content of plant nutrients in the soil is low, the organic matter is seriously lacking, the physical, chemical and biological properties are poor, and it is difficult for plants to grow well

Embodiment 1

[0017] This mobile road plant waste composting device is used for aerobic treatment of plant waste generated during the construction period of Mashi Town, Shixing County, Shaogan Expressway. The base of the pile is 8m long, 2m wide and 1m high. The composting time was 65d, and the sampling time was 5d, 10d, 15d, 30d and 60d.

[0018] On the 60th day of composting, the color of the compost turns brown or black, and the compost material is completely softened and deformed, and it is easy to break. It can be seen from Table 1 that the pH value and the total nutrients increased to varying degrees, and on the 30th day of composting, the organic matter content of the compost decreased by 46.5%, and its C / N was 18.95%, which was close to the theoretical value of compost maturity. The seed germination index of the compost product in this experiment was 96.12%, which was significantly higher than the maturity index GI>80%, indicating that the plant waste compost had reached complete m...

Abstract

Aiming at the temporary and linear characteristics of highway construction, the present invention provides a mobile forced ventilation static stacking system device, which aims to solve the resource waste and environmental pollution of highway plant waste without interfering with each other and affecting construction. It is composed of generator, centrifugal fan, ventilation duct and stack. The generator and centrifugal fan can be disassembled and moved, and the mobile energy can meet the requirements of composting at multiple points on the road at the same time. The device has a simple structure, is easy to install and reuse, and reduces costs. Because the present invention adopts the oxygen supply mode of forced ventilation, it can meet the oxygen requirement for decomposing and decomposing the compost material, the composting cycle is short, the compost product conforms to the quality standard and the organic fertilizer standard, and can be directly used as the road greening planting substrate.

Description

technical field [0001] The invention belongs to the field of biodegradation of waste, and in particular relates to a device and a method for a forced ventilation static pile composting system used for processing road plant waste. Background technique [0002] In the construction of highway engineering, it is often necessary to excavate a large number of side slopes, destroying the vegetation coverage of the original road area, resulting in a large number of secondary bare land and serious soil erosion, and generating a large amount of engineering waste and plant waste . Due to the large scale of highway projects, long construction period, temporary power consumption, and complicated pipeline facilities, at present, there are few separate measures to properly dispose of these plant wastes in engineering. The generated construction waste is landfilled together, causing negative impacts such as land occupation and environmental pollution. [0003] However, these plant wastes ...
