Turning strip stack composting process

Abstract

The invention belongs to the technical field of composting, and provides a turning strip stack composting process. The process comprises the following steps of: (1) performing impurity removal and crushing, specifically, removing impurities from organic materials, and then crushing the organic materials; (2) performing material mixing, specifically, mixing the organic materials treated in the step (1) with an organic decomposition agent and urea in proportion to obtain a mixed material; (3) performing composting, specifically, composting the mixed material to form a compost; (4) performing composting fermentation; and (5) performing composting decomposing. In the step (4), in the composting fermentation process, the compost is turned and thrown. According to the turning strip stack composting process of the invention, turning is applied to a composting technology, materials at a core part and an outer layer of the compost are fully mixed by turning to accelerate the fermentation process, and meanwhile, weed seeds, bacteria, larvae and the like at the outer layer of the compost can be moved to a high-temperature area in the compost to enhance a killing effect; and the temperature of the compost can be reasonably regulated and controlled through turning, so that the temperature of the compost is within a proper temperature range, and the composting quality and effect are ensured.

Description

technical field [0001] The invention belongs to the technical field of composting, and in particular relates to a composting process of turning and throwing bar piles. Background technique [0002] Composting is the use of various organic wastes (such as crop straw, weeds, leaves, peat, 00 organic domestic waste, kitchen waste, sludge, human and animal excrement, distiller's grains, fungus chaff and other waste, etc.) as the main raw materials. An organic fertilizer made by composting and decomposing. At present, the stacking composting technology is commonly used. In the existing technology, the composting process is generally as follows: first, the ingredients are prepared, that is, the raw materials are configured and processed according to different materials, and then the ventilation channels are set and the materials are piled up on the stacking field. After the accumulation is completed, post-heap management is carried out until it becomes decomposed. The existing c...

Problems solved by technology

[0003] The purpose of the present invention is to provide a composting process of turning and throwing strips to solve the problem of poor management after composting in the prior art, poor killing effect of weed seeds, bacteria, larvae, etc. in the material, and difficulty in composting temperature. Technical issues such as maintaining a reasonable composting temperature range
