Description

City fallen leaves treatment facility

Technical Field

The utility model belongs to the technical field of industrial machine, especially, relate to an urban fallen leaves treatment facility.

Background

With the enlargement of urban greening area, the dry branches and fallen leaves are also generated in large quantity in autumn and winter. For a long time, urban fallen leaves have been one of the main problems troubling the urban construction department. In pursuit of neat and beautiful appearance, the urban dry branches and fallen leaves are often regarded as urban solid waste, become clear objects of green space maintenance management, and the urban fallen leaves cleaning work is implemented as an important index for measuring maintenance fineness level. When autumn wind comes and fallen leaves fall with the wind, and sanitation workers feel the most arduous and busy, the fallen leaves in greenbelts and parks are thoroughly cleaned and even packaged and transported, and the fallen leaves enter a garbage station along with household garbage under most conditions. The method not only increases the pressure of city appearance environment management, but also breaks the material circulation and energy flow of the green space ecosystem, and restricts the improvement of the urban green space productivity. In addition, a large amount of manpower and material resources are consumed in the urban fallen leaves treatment process, and meanwhile, resource waste is caused, so that a more effective treatment method for urban fallen leaves is urgently needed to be found. At present, the treatment mode of greening wastes such as urban residual branches and fallen leaves is mainly to transport the greening wastes out along with domestic wastes, and finally to landfill or incineration is carried out in a landfill site. Only a few parts are subjected to resource treatment. These methods all have certain limitations:

the collecting and burying operations are simple, but the occupied area is large, and leachate, gas and the like generated after the landfill cause harm to the surrounding environment and possibly generate secondary pollution.

Harmful gases such as carbon monoxide, hydrogen sulfide, formaldehyde and the like, and solid particles such as carbon black, dust, soot and the like exist in smoke generated by the incineration mode, the air pollution is greatly influenced, and the urban fallen leaf incineration treatment mode is strictly forbidden at the present stage.

The composting mode is reasonable, but the conversion time is long, the problem of polluting the surrounding environment to a certain extent can be caused by a large amount of fallen leaves, and the method is obviously not suitable for treating the fallen leaves of the city by adopting the compost around the city. Therefore, a more reasonable, economical and environment-friendly treatment device for treating urban fallen leaves is urgently needed.

Moreover, improper treatment of fallen leaves not only increases the pressure of urban capacity environment management, but also causes the breakage of the material circulation and energy flow of the green space ecosystem, the self-maintenance of the soil fertility cannot be achieved, the soil quality is reduced, and the improvement of the urban green space productivity is restricted. Therefore, there is a need to research the characteristics, functions and ecological utilization ways of the dry branches and leaves of the green lands, so as to promote the substance circulation of the green land ecological system, the soil self-fertilization process and the exertion of the self-maintenance mechanism and improve the self-regulation and development capability of the green lands. Urban fallen leaves are also rich in nutrient substances, and the realization of ecological cycle among substances by a biotransformation method is a necessary choice for treatment of the fallen leaves in the future. The method treats the urban fallen leaves and the domestic garbage equally, so that the nutrient substances in the urban green land continuously flow out and cannot be supplemented in time, the resource waste is caused, meanwhile, the soil degradation is gradually caused, and the ecological balance of the green land is destroyed. It is not easy to treat fallen leaves in the city. Firstly, the environmental conditions of the production places of urban fallen leaves are different, the shapes of the leaves are different, and branches, plastics and the like with different sizes are doped, stone particles, metal sheets and the like can be mixed during collection, secondly, the fallen leaves have high moisture, and the traditional crushing equipment cannot meet the ideal requirements.
