Method for producing active ecological organic raw material by using anaerobic process

Abstract

The invention discloses a method for producing an active ecological organic raw material by using an anaerobic process. The method comprises the steps of conveying organic wastes such as chicken manure, pig manure, cow dung, kitchen waste or domestic sludge with the water content of 50-90% into a sterilization device through a screw conveyer, and carrying out physical sterilization treatment for 5-10 minutes; adding nitrogen-fixing flora, uniformly stirring, and putting into a fermentation tray; and putting the fermentation tray into a constant-temperature reactor, keeping the fermentation temperature at 15-50 DEG C and the humidity at 40-70%, and carrying out sealed fermentation in an anaerobic environment for 15-45 days to obtain the active ecological organic raw material. In the fermentation process, auxiliary materials are not added, turning or oxygenation is not carried out, emission of ammonia nitrogen to air is reduced, energy consumption is low, the problem of environmental pollution is solved, the recycling value of organic waste is improved, and good economic value and wide market prospects are achieved.

Description

technical field [0001] The invention relates to a method for producing active ecological organic fertilizers, in particular to a method for producing active ecological organic raw materials using an anaerobic process, which belongs to the technical field of resource reuse. Background technique [0002] Organic waste such as chicken manure, pig manure and cow manure produced in the livestock and poultry breeding industry, as well as kitchen waste and domestic sludge produced in daily life, is rich in organic matter and nutrients such as nitrogen, phosphorus and potassium, and is a kind of sustainable Valuable resource for development and utilization. However, at present, auxiliary materials need to be added during the fermentation process of organic waste, and oxygenation or stirring is also required during fermentation, which not only leads to the discharge of ammonia nitrogen into the air, causing air pollution, but also causes a lot of nutrient loss of organic raw material...
