Abstract

The invention discloses an anaerobic biogas slurry treatment process, and belongs to the related technical field of anaerobic biogas slurry treatment. The anaerobic biogas slurry treatment process comprises the following steps: step A: aeration, step B: precipitation, step C: filter pressing, step D: catalytic oxidation, step E: MBBR, step F: RO / AC, and step G: discharge. The invention further discloses anaerobic biogas slurry treatment equipment which comprises supporting legs, a treatment box is fixedly connected to the top ends of the supporting legs, a feeding pipe is fixedly connected tothe middle of the top end of the treatment box, air cylinders are fixedly mounted in the middles of the two sides of the treatment box, and telescopic rods are fixedly connected to the middles of onesides of the air cylinders. In treatment process,biogas slurry is subjected to aerobic aeration treatment through efficient micro-nano air active oxygen bubbles, anaerobic microorganisms in the biogasslurry are killed or are promoted to sleep, and suspended solids and organic matters in the biogas slurry are oxidized at the same time, so that the flocculating settling effect is improved. Resultsshow thatbiogas slurry flocculation and sedimentationeffect is impossible to achieve without aerobic aeration treatment.

Description

technical field

[0001] The invention relates to the technical field related to the treatment of anaerobic biogas slurry, in particular to a treatment process of anaerobic biogas slurry. Background technique

[0002] Anaerobic is a commonly used process in the treatment of high-concentration organic wastewater such as kitchen wastewater and aquaculture wastewater, and it is also a common resource (gasification) treatment method for perishable organic matter. Organic matter is degraded under the action of anaerobic microorganisms. Due to the difference in the initial organic matter, the molecular state at the end of anaerobic is different, resulting in the distribution of organic matter in anaerobic biogas slurry is different from that of ordinary wastewater, resulting in the degradation of biogas slurry COD by the usual Fenton oxidation and microbial treatment processes are difficult to work, and they are generally diluted and discharged after treatment to a certain extent. ...
