Abstract

The invention discloses a compost building method for food waste organic matter aerobic composting. The method comprises the steps that 1, a layer of conditioner is laid inside a composting groove; 2, a food waste organic matter is laid on the conditioner; 3, a layer of conditioner is laid on the food waste organic matter; 4, the steps 2 and 3 are executed again to obtain a mixed material; 5, the obtained mixture is stacked into strip-shaped composts; 6, after the whole composting groove is filled with the material composts, a waterproof ventilation membrane is spread; 7, a sensor is inserted, ventilation is enabled, and fermentation residues are obtained 20-40 days after one-time aerobic fermentation; 8, the fermentation residues are transferred to another groove, the steps 5 and 6 are executed again, and the composts are obtained 7-20 days after second-time aerobic fermentation. According to the composting method, the conditioners are laid inside the composting groove, mixed composting is performed on the conditioners and the food waste organic matter, the composts have the better porosity, and air circulation is promoted, so that the aerobic composting process is uniform in fermentation, the composting quality is improved, and the composting period is shortened.

Description

technical field [0001] The invention relates to the field of cleaning and treatment of organic solid waste, in particular to a method for building a heap of kitchen waste organic matter aerobic composting. Background technique [0002] Membrane-covered high-temperature aerobic fermentation process is a process in which a special waterproof and breathable membrane is used as an aerobic fermentation treatment cover for fermentation. The core of the process is a waterproof and breathable membrane with special micropores. Its semi-permeable function can realize a relatively constant climate environment, so that water vapor and carbon dioxide can diffuse out through the microporous structure of the membrane, and block hydrogen sulfide and ammonia. Harmful gases such as gas pass through. Under the action of air blast, a slightly high-pressure inner cavity can be formed in the fermentation body, so that the heap body can supply oxygen evenly and fully, and the temperature distri...
