High speed composting method using AT-18 enzyme composition

Abstract

The invention relates to a high speed composting method using an AT-18 enzyme composition. The method comprises the steps of adjusting the carbon nitrogen ratio and water content of an organic waste, placing in a fermenting machine, heating the fermenting machine from 25 DEG C to 80 DEG C within an hour, and after maintaining for three hours at 80 DEG C, cooling the fermenting machine to 55 DEG C and maintaining for 15 hours; adding the AT-18 enzyme composition into the fermenting machine, wherein the additive amount is 1-5% of total weight (the organic waste plus the AT-18 enzyme composition); without continuously heating in the fermenting machine, composting in a mechanical stirring method and/or increasing the oxygen supply by mechanical ventilation for about 18 hours, so that the organic waste is decomposed to an organic fertilizer.

Description

technical field [0001] The invention relates to a method for making organic compost, in particular to a high-speed composting method using AT-18 enzyme composition, which can more efficiently convert organic waste into organic fertilizer through composting and fermentation. Background technique [0002] In today's society with rapid population growth and rapid development of industry and agriculture, a large amount of agricultural and livestock waste has had a great impact on the environment in which we live. It not only takes up a lot of space, but also causes environmental pollution, thereby reducing our life. Quality, if it is left to be discarded and buried, it may cause water or soil pollution; if it is incinerated, it will cause ash, carbon dioxide and Dioxins to form, and even threaten human survival. [0003] How to properly solve the pollution of organic waste, and then recycle organic waste to increase its utilization value, are the goals of active efforts of gover...

Problems solved by technology

[0004] Humans have used composting to process agricultural waste as fertilizer for grain production for more than 4,000 years. It was not until the invention of chemical fertilizers that composting gradually lost its advantages; It can work immediately, but chemical fertilizers mainly provide nitrogen, phosphorus, and potassium, the three elements most needed by plants, and the produced vegetables may have residual substances in chemical fertilizers, such as nitrate; moreover, plant growth requires many other trace elements, and plants cannot Obtained from chemical fertilizers, they can only absorb other required nutrients from the soil. In the long run, the soil fertilized with chemical fertilizers will gradually lack trace elements. In addition to causing damage to the growth of plants, the soil Loss of nutrient balance makes the soil lean and barren
