Embodiment

[0011] The composting period is 15 days, and the composting materials are vegetable waste (celery, cabbage, cabbage, etc.) %. The composting starts in two composting bins respectively. At the beginning of composting, 300kg of vegetable waste and flower straw are added to each composting bin, and 300kg of vegetable waste is added to each composting bin after composting for 4 days and 8 days respectively. and 150kg, after 8 days, compost the materials in the two compost bins together. During the composting process, the temperature of the compost body is controlled at 55-65°C and 70-75°C respectively. After the composting is completed, the moisture content and organic matter content of the materials are respectively 55%. and 56%, the temperature of the pile body is 43°C, and it can be applied to the farmland as an organic fertilizer after one month of decomposing.

Abstract

The present invention is one kind of effective organic waste treating technology. The present invention produces compost through the cooperative effect of high-moisture easy-to-degrade organic waste and hard-to-degrade organic waste. Proper amount of high-moisture easy-to-degrade organic waste is added regularly to maintain the optimized compost producing condition with relatively higher density of easy-to-degrade organic waste and hard-to-degrade organic waste to provide high porous structure and unlimited oxygen transmission.

Description

technical field [0001] The invention belongs to the technical scope of organic waste treatment, and in particular relates to a rapid co-composting method of high-moisture easily degradable organic waste and refractory organic waste. Background technique [0002] With the improvement of people's living standards, my country's vegetable and flower planting industry and catering industry have developed rapidly, producing more and more high-moisture and easily degradable organic wastes and refractory organic wastes, which have also brought increasingly serious environmental pollution. Composting of waste, the production of organic fertilizer can turn waste into treasure, improve soil physical structure, alleviate soil compaction caused by large-scale application of chemical fertilizers, and improve soil organic matter, which has a win-win meaning. However, high-moisture and easily degradable organic wastes (such as vegetable wastes, catering industry wastes, etc.) have high moist...
