Method and equipment used for preparing water retention biological organic fertilizer from livestock and poultry urine through solidification

Abstract

The invention provides a method and equipment used for preparing a water retention biological organic fertilizer from livestock and poultry urine through solidification. The equipment comprises a vertical tower type fermentation cabin body, a night soil collecting pit, a paste pump, an auxiliary material cabin, a vacuum pump, a hydraulic power station, a biological filter tower, and a remote control terminal. According to the method and the equipment, a biological solidification conditioning agent, a biological decomposition agent, and a high temperature resistant aerobic biological bacterialstrain are adopted, the vertical tower type fermentation cabin body is adopted for high efficiency high temperature fermentation of pollutants, the whole fermentation period is controlled to be 7 to 10 days, fermentation temperature can be as high as 80 DEG C, and pathogen and weed seed killing rate is 98%; at the same time, biological solidification technology is adopted for solidification of thepollutants, so that rapid heating fermentation decomposition harmlessness treatment of high water content pollutants with water content higher than 80% can be realized under the effects of the aerobic microbial bacterial strain.

Description

technical field [0001] The invention relates to the field of organic fertilizer preparation, in particular to a method and equipment for preparing water-retaining bio-organic fertilizer by solidifying livestock and poultry urine.
