Anaerobic Fermentation Process and Advantages

The Anaerobic Fermentation Process usually includes the following steps:

  1. Pretreatment: including impurity removal, material crushing, pulping and stirring, in order to improve the fermentability of materials and reduce the difficulty of operation.For example, for viscous organic matter, it is necessary to add chemical agents or biological treatment agents for pretreatment.
  2. blowdown and conveying: conveying the pretreated materials into a fermentation tank. The conveying mode can be gravity conveying, mechanical conveying, pneumatic conveying and the like.
  3. anaerobic fermentation: placing the materials in a fermentation tank for fermentation.Certain environmental factors, such as temperature, pH, pressure and reaction time, need to be controlled in the fermentation tank to ensure the normal growth and metabolism of anaerobic bacteria. The products produced in the fermentation process need to be discharged regularly and recycled through post-treatment.
  4. post-treatment: separating, refining, processing and the like are carried out on the product generated by fermentation and conversion to obtain the target product. For example, biogas produced by anaerobic fermentation can be used for power generation or heat utilization, and sludge can be treated by biological drying. The above is a simple anaerobic fermentation process. Different materials, reaction conditions and requirements will have different processes and steps.

Advantages of Anaerobic Fermentation:

  1. The treatment effect of the waste with high moisture content is good. Compared with the traditional composting method, the anaerobic fermentation does not generate leachate, thereby reducing the cost of waste treatment.
  1. Biogas produced in the fermentation process can be recycled as energy. Anaerobic fermentation is a way of energy recycling, and the biogas produced by anaerobic fermentation can be used for heating, power generation and other energy supply.
  2. Changes in the number and types of microorganisms in the fermentation process play a more significant role in inhibiting odor, viruses and harmful substances. Short time and high efficiency. Compared with traditional composting, anaerobic fermentation takes only half the time to decompose kitchen waste into fertilizer and biogas.
  3. Small footprint. Compared with landfill and incineration, the anaerobic fermentation method for treating kitchen waste does not need to use a large area of land, so it can save a lot of land investment and management costs.
