Composting method for inoculating compound bacterium agent in secondary fermentation stage

Abstract

The invention relates to a composting method for inoculating a compound bacterium agent in a secondary fermentation stage, belonging to the field of resource recycling of solid waste. The composting method comprises the following specific steps: extracting advantageous bacterium group at the high temperature period of the secondary fermentation stage of domestic garbage, culturing and acclimatingand obtaining the compound bacterium agent. In the initial stage of secondary fermentation, the compound bacterium agent is inoculated by 1 to 5 percent of inoculum size, and compared with the composting method without inoculating the domestic garbage, the composting method of the invention advances the high temperature period of the secondary fermentation by 5 to 15 hours, prolongs the high temperature duration by 15 to 31 hours, and shortens the composting time of the secondary fermentation by 4 to 10 days, thus shortening the whole composting period, and improving the production efficiencyof compost. The composting method has obvious economic benefit, simple method and process and convenient application.

Description

technical field [0001] The invention belongs to the field of resource utilization of solid waste, and specifically relates to extracting dominant flora in the high-temperature section of secondary fermentation of domestic garbage, enriching and cultivating them, and inoculating them at the initial stage of secondary fermentation of domestic garbage after enrichment and cultivation. The high temperature period of the secondary fermentation is advanced, the duration of the high temperature period is prolonged, the secondary fermentation time is shortened, and the composting process of domestic waste is accelerated. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, the amount of garbage discharge is increasing day by day. The world adds more than 10 billion tons of garbage every year, which poses a great threat to the living environment of human beings. According to statistics, my country's annual...
