Embodiment 1

[0024] Step 1. Use a double-shaft toothed roller crusher to crush 450 kg of kitchen waste to a length of 1 cm, then place the kitchen waste in a well-ventilated fermentation bin for natural composting and fermentation, and perform proper composting according to conventional composting operations during the period , the turning interval is 2 days.

[0025] Step 2. After composting for 18 days (at this time, the temperature is 47°C and the pH is 5.2. The highest temperature occurs on the 13th day, and the temperature is 61°C), add 40 kg of iron-carbon particles (iron-carbon mixed particles) to the heap , the particle size is 5cm, the porosity is 68%, and the mass ratio of iron to carbon is 5:1) and mixed evenly. After 11 days of continuous fermentation, the indicators of the compost tend to be stable, the temperature is about 28°C, and the pH is 5.7.

[0026] Step 3. After the composting fermentation is finished, the iron-carbon particles are sieved through a 3cm square hole sie...

Embodiment 2

[0030] Step 1. Use a double-shaft toothed roller crusher to crush 620 kg of kitchen waste to a length of 1 cm, and then place the kitchen waste in a ventilated fermentation bin for natural composting and fermentation. During the period, perform proper composting according to conventional composting operations , the turning interval is 2 days.

[0031] Step 2. After 18 days of composting and fermentation (at this time, the temperature is 49°C and the pH is 5.4. The highest temperature occurs on the 11th day, and the temperature is 63°C), add 40 kg of iron-carbon particles (iron-carbon mixed particles) to the heap , the particle size is 5cm, the porosity is 68%, and the mass ratio of iron to carbon is 5:1) and mixed evenly. After 15 days of continuous fermentation, the compost indicators tend to be stable, the temperature is about 29°C, and the pH is 6.3.

[0032] Step 3. After the composting fermentation is finished, the iron-carbon particles are sieved through a 3cm square hol...

Abstract

The invention discloses a novel method for composting fermentation of kitchen garbage. The method comprises the following steps: in the composting fermentation process of the kitchen garbage, mixing iron-carbon particles into a pile body, and continuously fermenting until the pile body is thoroughly decomposed. By utilizing the method disclosed by the invention, the fermentation period can be remarkably shortened, the quality of the obtained bio-organic fertilizer is improved, and meanwhile, the number of beneficial viable bacteria in the bio-organic fertilizer is increased.

Description

technical field [0001] The invention relates to a new method for composting and fermenting kitchen waste, and belongs to the technical field of kitchen waste treatment. Background technique [0002] Kitchen waste is a general term for household kitchen waste, dining waste and other kitchen waste. It is the organic waste generated by people in the production process of life. With the increasing pressure of terminal disposal and the increasing requirements for the regeneration and utilization of organic resources, the requirements for the fermentation process of kitchen waste are also getting higher and higher. The aerobic fermentation process of traditional composting takes a long time, which directly causes problems such as large floor space. At the same time, the aerobic fermentation process of traditional composting often requires the addition of a large proportion of auxiliary materials for mixed fermentation, resulting in increased processing costs, and the auxiliary ma...
