Embodiment 1

[0024] Such as figure 1 As shown, a treatment method of rural kitchen waste covered with film-covered aerobic fermentation combined with vermicomposting includes three steps: kitchen waste pretreatment, film-covered aerobic fermentation treatment, and vermicomposting treatment. The specific steps are as follows:

[0025] Step 1: Mechanical pretreatment of kitchen waste: The collected rural kitchen waste is crushed, deoiled and desalted, solid-liquid separated, and the separated liquid is treated for wastewater, and then reused after reaching the standard.

[0026] Among them, the separated oil is collected during the desalination and oil removal process, and then converted into biodiesel or detergent after reprocessing. The saline wastewater is subjected to advanced treatment, and the purified circulating water can be used in the aerobic fermentation process and vermicomposting process.

[0027] Step 2: Film-covered aerobic fermentation treatment: Mix the solids separated in ...

Embodiment 2

[0033] Such as figure 1 As shown, a treatment method of rural kitchen waste covered with film-covered aerobic fermentation combined with vermicomposting includes three steps: kitchen waste pretreatment, film-covered aerobic fermentation treatment, and vermicomposting treatment. The specific steps are as follows:

[0034] Step 1: Mechanical pretreatment of kitchen waste: crush the collected rural kitchen waste, degrease and desalt, and separate solid and liquid. The separated liquid is treated with waste water and reused after reaching the standard.

[0035] Among them, in the process of desalination and deoiling, the separated oil is collected and reprocessed into biodiesel or washing products. The saline wastewater is treated in depth, and the purified circulating water can be used in the aerobic fermentation process and vermicomposting process, saving water resources.

[0036] Step 2: Film-covered aerobic fermentation treatment: Mix the solids separated in Step 1 with the ...

Embodiment 3

[0042] Such as figure 1 As shown, a treatment method of rural kitchen waste covered with film-covered aerobic fermentation combined with vermicomposting includes three steps: kitchen waste pretreatment, film-covered aerobic fermentation treatment, and vermicomposting treatment. The specific steps are as follows:

[0043] Step 1: Mechanical pretreatment of kitchen waste: crush the collected rural kitchen waste, degrease and desalt, and separate solid and liquid. The separated liquid is treated with waste water and reused after reaching the standard.

[0044] Among them, in the process of desalination and deoiling, the separated oil is collected and reprocessed into biodiesel or washing products. The saline wastewater is treated in depth, and the purified circulating water can be used in the aerobic fermentation process and vermicomposting process, saving water resources.

[0045] Step 2: Film-covered aerobic fermentation treatment: Mix the solids separated in Step 1 with the ...

Abstract

The invention provides a method for treating rural kitchen garbage by combining film-covering aerobic fermentation with earthworm composting. The method comprises the steps of mechanical pretreatment of kitchen garbage, film-covering aerobic fermentation treatment and earthworm composting treatment. According to the method disclosed by the invention, the kitchen waste is subjected to combined treatment by various technologies such as mechanical pretreatment, film-covering aerobic fermentation treatment and earthworm composting treatment according to the principle of reduction, harmlessness and waste recycling, and therefore, the rural kitchen garbage and a proper amount of agricultural waste are converted into an organic medium, namely wormcast. According to the method, the defects of a single kitchen garbage treatment technology in the prior art are overcome, the environmental problems of soil salinization, odor pollution and the like caused by direct aerobic composting of the kitchen garbage are solved, a kitchen garbage treatment period is shortened, agricultural waste is also consumed in the treatment process, and the working pressure of rural environment improvement is relieved. Meanwhile, the finally-converted wormcast can be used for soil improvement, so the use amount of chemical fertilizers is reduced, soil fertility is effectively improved, and the problems of soil hardening, low nutrient content and the like in agricultural production are solved.

Description

technical field [0001] The invention relates to the technical field of rural kitchen waste treatment, in particular to a treatment method of rural kitchen waste covered with aerobic fermentation and earthworm composting. Background technique [0002] With the implementation of my country's rural revitalization policy, the development of urbanization has also changed the way of life in rural areas. Since the implementation of domestic waste classification, the amount of rural kitchen waste has risen sharply. Kitchen waste has the characteristics of high moisture content, high organic matter content, and perishability. If kitchen waste is not disposed of in time, it will seriously affect the surrounding environment and the health of residents. At present, the conventional disposal methods of kitchen waste include landfill, incineration, aerobic composting, and anaerobic fermentation. The landfill method is to degrade the landfilled kitchen waste through the microbial flora ...
