Self-refluxing circulating nitrification device and vegetable residue treatment system using the same

Abstract

The invention discloses a self-refluxing circulating nitrification device and a vegetable residue treatment system using the same and relates to the technical field of agricultural pollutant recycling. The device solves the problem that the existing device cannot effectively control the accumulation of ammonia during the fermentation of vegetable residues to cause poor anaerobic fermentation device stability. The self-refluxing circulating nitrification device comprises a first reactor and a second reactor. A material outlet of the first reactor is communicated with a material inlet of the second reactor. A material outlet of the second reactor is communicated with a material inlet of the first reactor. The first reactor comprises acid-forming bacteria. The first reactor is used for fermentation treatment on vegetable residues. The second reactor comprises methanogens. The second reactor is used for fermentation treatment on the fermentation residues discharged by the first reactor. The fermentation residues discharged by the second reactor is returned into the first reactor. The invention is mainly applied to the construction and manufacture of the self-refluxing circulating nitrification device and the vegetable residue treatment system using the same.

Description

technical field [0001] The invention relates to the technical field of recycling and reuse of agricultural pollutants, in particular to a self-reflux circulating nitrification device and a tail vegetable treatment system using the same. Background technique [0002] Tail vegetables refer to the residual leaves of fresh vegetables that must be removed when they are harvested, transported or eaten. With the improvement of living needs, the planting area of ​​vegetables in various places has expanded year by year, followed by the production of a large number of tail vegetables. This situation is particularly prominent in some major vegetable producing areas and has become a major source of pollution in the region. While the vegetable industry has brought good economic benefits to vegetable farmers, the resulting tail vegetables have also brought difficulties to agriculture and rural environmental protection. Therefore, it is of great significance to study how to deal with or ut...
