Problems solved by technology

This kind of garbage is different from municipal solid waste. It is composed of cellulose, hemicellulose and lignin. It is directly burned, which not only pollutes the atmosphere, but also has a low calorific value and is not easy to use; if it is landfilled, although it can rely on soil It can be degraded by its own ability, but the degradation time is long, the nutrients in the soil are consumed, and the utilization rate is low; if it is piled up for a long time, it will not only occupy the land, but also as time goes by, the piled material will ferment by itself, producing stench and leachate , severely damage the surrounding environment, and have a great impact on people's normal life

Abstract

The invention relates to a method for degrading landscaping garbage to produce an organic fertilizer by utilizing high-efficiency mixed bacteria, which comprises the steps: (1) organic matters of the landscaping garbage are sterilized after being crushed; (2) nutrition substrates, lignin and cellulose degradation bacteria are added to the solid phase; (3) the mixture is irradiated for 20 minutes every other 8 hours by adopting low-frequency ultrasonic wave until the fourth to seventh day of the fermentation cultivation after the fermentation cultivation for 24 to 26h; and (4) the sterilization processing is carried out to obtain the finished product organic fertilizer after the thoroughly decomposition for 1 to 3 days. The method has the advantages of simple required equipment, simple andconvenient process, and safety disposal realization of the landscaping garbage. Meanwhile, the method produces the organic fertilizer capable of promoting the growth of crops, solves the difficultiesof difficult degradation and difficult recycle of the current landscaping garbage, and has extremely profound social significance and economic value.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a method for producing organic fertilizer by degrading landscaping garbage with high-efficiency mixed bacterial agents. Background technique [0002] In the process of urbanization, the deforestation of the original forests and flowers in the city has led to a sharp deterioration of the urban environmental quality and accelerated global warming. In order to improve the quality of urban environment and delay global warming, urban greening has become an effective means to solve this problem. Urban greening is to plant trees, grasses and flowers in the city to cover or decorate a certain ground (space). Many cities carry out greening work in combination with road construction, river improvement and old city renovation, effectively increasing the area of ​​green land, creating activities for gardening streets, communities and units, and promoting the integration of ...
