Description

Equipment for preparing ecological soil by using kitchen garbage

Technical Field

The utility model relates to a rubbish is useless technical field admittedly, concretely relates to equipment of ecological soil of application rubbish from cooking system.

Background

The kitchen waste is an important component of organic waste in the municipal solid waste, mainly comprises rice and flour food residues, vegetables, vegetable oil, animal oil, meat and bones, fishbone and other organic matters which can be decomposed by microorganisms, and has the basic physicochemical characteristics of high moisture (about 80-85 percent) and high organic matter content, various microorganism types, nitrogen, phosphorus, potassium, calcium and various trace elements, and the oil content is far higher than that of other organic waste. In order to build a green environment, how to effectively treat kitchen garbage is a difficult problem which needs to be solved urgently.

In the prior art, the recycling treatment mode of the kitchen garbage mainly comprises the modes of feed conversion, energy production and power supply, composting, anaerobic digestion to produce methane, anaerobic fermentation to produce hydrogen, biodiesel preparation, biodegradable plastic production, biological pesticide production and the like. The composting technology is to pile the kitchen waste on the ground or place the kitchen waste in a certain fermentation device, and gradually degrade easily degradable organic matters in the kitchen waste by using microorganisms to finally form stable humus. The product of the kitchen waste after composting is not only a soil conditioner, but also a high-quality fertilizer. The prior composting technology mainly comprises the following steps: aerobic composting and earthworm composting.

The aerobic composting technology is a composting technology combining the traditional aerobic composting technology with the strengthening effect of external biological strains. The research on the aspect is mature, and shows that the temperature rise speed is high, the duration time of a high-temperature period is long, the water content and organic matters are obviously reduced, the emitted odor is less, the germination rate is high after one-time composting, and the decomposition is basically realized when the kitchen garbage and the mushroom residue are mixed and subjected to aerobic composting. The influence of the ventilation quantity on the temperature and the water content of the piled materials is obvious, and a proper ventilation quantity is found through experiments. When the initial temperature is 40 ℃, the decomposition time of the compost can be effectively accelerated, the composting time is shortened, and the harmless requirement of compost products is met. The aerobic composting treatment technology of the kitchen waste has the advantages of low operation cost, convenient operation and maintenance, capability of preparing a compound fertilizer by using the product, and the like. The disadvantages are that the quality of the organic fertilizer is greatly influenced by the components of the kitchen waste, the energy consumption is large, the operation process is complicated, and the like. In addition, the high content of grease in the kitchen waste is not beneficial to the growth of microorganisms, and the treatment effect of the aerobic composting process is restricted.

The earthworm composting is characterized in that earthworms are put into the earthworm composting on the basis of aerobic composting, and kitchen waste organic matters are converted into self or other nutrient substances which are easy to utilize by utilizing the own abundant enzyme system of the earthworms, so that the stabilization process of the composting is accelerated. The earthworms swallow a large amount of organic substances in the metabolism process, mix the organic substances with soil, and promote the decomposition and transformation of the organic substances through the mechanical grinding effect of the sand bag and the biochemical effect in the intestinal tract. The earthworm composting technology is considered to be an ecological environment-friendly technology, which not only can treat a large amount of organic wastes and reduce the influence on the surrounding environment, but also can obtain efficient and stable organic fertilizer. In addition, the earthworms have the function of accumulating heavy metals, so that the heavy metal forms can be changed by the activity of the earthworms, and the influence of compost products on the environment is reduced. The disadvantages of earthworm composting are that earthworms have high requirements on the growth environment, need proper temperature, pH, humidity and ventilation degree, and have longer period of using earthworm composting.

Therefore, only by continuously summarizing the actual operation experience of the kitchen waste recycling project, a new treatment technology is developed, the problems of air pollution, water pollution, soil pollution and the like caused by carbon emission in the kitchen waste treatment process are solved, the harmlessness, recycling and reduction of kitchen waste are really realized, the environmental friendliness and recycling are realized, and a good foundation is laid for the sustainable development of resources and environment.
