Three stage temperature control method for preparing compost

Abstract

A three-stage temp. control process for preparing compost includes such steps as quickly raising temp. to 75 deg.C within 3-5 hr by the heat generated by its self, keeping the temp for 6-10 hr for killing hetero-bacteria, cooling, inoculating composite microbial bacteria for compost, natural fermenting until its temp. reaches 60 deg.C, cooling to obtain functional bacterial fertilizer, high-temp. sterilizing of new raw garbage, and inoculating the said functional bacterial fertilizer.

Description

technical field [0001] The invention relates to a method for fermenting organic fertilizer, in particular to a three-stage temperature-controlled composting method. Background technique [0002] The traditional composting method uses the indigenous microorganisms in the compost to decompose the organic matter in the garbage, which often has problems such as long fermentation time, odor and low fertilizer efficiency. However, the ability of microorganisms to decompose organic matter varies greatly in nature. In theory, inoculation of microorganisms with strong ability to decompose organic matter and resistance to extreme environments can increase the total number of high-efficiency microorganisms in the initial compost, accelerate the composting of compost materials, and eliminate certain pathogens, insect eggs and debris. Grass seeds, and control the production of odor, improve composting efficiency. However, due to the complexity of compost raw materials, there is competit...

AI Technical Summary

Problems solved by technology

However, due to the complexity of compost raw materials, there is competition between the inoculated microorganisms and a large number of indigenous microorganisms, which affects the growth and reproduction of the inoculated microorganisms and threatens their dominant position in the compost. agent, increasing the cost of composting
