Gradient low-temperature biological enrichment reactor

Abstract

The invention discloses a gradient low-temperature biological enrichment reactor. The gradient low-temperature biological enrichment reactor comprises a plurality of heat preservation boxes; a plurality of centrifugal tubes are arranged in each heat preservation box; the heat preservation boxes are communicated with a peristaltic pump, a condenser and an anti-freezing solution placing barrel bodyin sequence to form a circulation loop; and the condenser and the anti-freezing solution placing barrel are placed in a low-temperature control device. A plurality of centrifugal tubes in the biological enrichment reactor are sequentially connected in series, so that gradient low temperature can be realized; the low-temperature heat preservation effect of the centrifuge tube can be achieved by wrapping the centrifuge tube with a hose; low temperature in the hose can be realized by putting an anti-freezing solution into a refrigerator of -10 DEG C; the condenser is connected, so that the temperature of the centrifugal tube can be kept at 4-13 DEG C; and in order to achieve the overall liquidity of the anti-freezing solution, the hoses of all parts are connected through hose connectors. According to the anti-freezing solution in the hose, the solution in the hose is pumped through elastic conveying of the peristaltic pump and alternate extrusion and release of the hose, so that the solution in the whole reactor achieves the circulating reflux effect, and the low temperature of a compost sample in the centrifugal tube is kept.

Description

technical field [0001] The invention relates to a gradient low-temperature bio-enrichment reactor, which belongs to the technical field of organic waste recycling and microbial technology research and development. Background technique [0002] Composting refers to the fermentation of microorganisms using solid organic substrates by artificially adjusting conditions such as moisture, C / N, and ventilation. Through this process, waste organic matter in an unstable state is converted into stable humus. Aerobic fermentation is a biochemical process that relies on the action of obligate and facultative aerobic bacteria to degrade organic matter. The organic material to be composted and the filler are mixed in a certain proportion, and the microorganisms are reproduced and degraded under suitable moisture and ventilation conditions. Organic matter, thereby generating high temperature, killing pathogenic bacteria and weed seeds, and stabilizing organic matter. In the process of aer...
