Abstract

The invention discloses a composting method, comprising the following steps of: (1) mixing a composting raw material and a microbial inoculum to obtain a compost body; (2) fermenting the compost body at high temperature to obtain a primary composting product; and (3) continuing fermenting the primary compost product to obtain a fertilizer. Experiments prove that in the invention, based on the concepts that the activity and the diversity of microorganisms are promoted by high temperature in the composting process and large amount of heat energy is generated from the high-temperature decomposition of organic matters by microorganisms, the heat energy from high-temperature fermentation is also recycled in the composting process at the same time of adding the microorganism microbial inoculum in the composting process.

Description

technical field

[0001] The invention relates to a composting method. Background technique

[0002] With the acceleration of urbanization and the increasing amount of municipal solid waste, the city siege phenomenon and environmental pollution caused by municipal solid waste have become increasingly prominent. The disposal of municipal solid waste has become a major environmental problem faced by our country and countries all over the world. Composting technology is an important way to realize the harmlessness, reduction and recycling of domestic waste. Due to the poor maturity of compost products and the long composting cycle, it has become an important problem restricting the development of composting technology. Therefore, improving the compost maturity and shortening the composting cycle has become a key issue in solving the composting of domestic waste.

[0003] At present, there are mainly the following methods in shortening the composting cycle of domestic waste: 1. A...
