Embodiment 1

[0033] Example 1: This electromagnetic enhanced continuous fermentation method treats cow manure. The cow manure is fed from the feed port into a fermentation chamber uniformly equipped with an array of hollow perforated electrode pairs. The fermentation raw material is cut through the hollow perforated electrode pair and then placed on the hollow perforated electrode Between the pairs, the air is blown into the fermentation raw materials through the hollow perforated electrode pair to aerate the fermentation raw materials to ensure that the fermentation raw materials in different stages are in a fully and evenly mixed state. The electrochemical action in the fermentation process produces free radicals, and at the same time heavy metals are transformed into soluble forms from the fermentation raw materials and move out into the fermentation broth through electrochemical action, and the positively charged heavy metal ions are enriched in the hollow perforated electrode pair. On ...

Abstract

The invention discloses an electromagnetically enhanced continuous fermentation method and device. A fermentation raw material enters a fermentation chamber, which is uniformly provided with hollow perforated electrode pair arrays, from a feeding hole and is arranged between hollow perforated electrode pairs after being cut through the hollow perforated electrode pairs, and gas is blown into the fermentation raw material through the hollow perforated electrode pairs for aeration in order to ensure that the fermentation raw material at different stages is fully and uniformly mixed. A micro-voltage is applied to the hollow perforated electrode pairs during a fermentation process at the temperature of 15 to 70 DEG C, and meanwhile a magnetic field is applied to the fermentation raw material in the fermentation process. A continuous fermentation way is adopted during fermentation to increase the production efficiency. Leachate, volatile ammonia and a fermentation product are collected in the fermentation process to prepare fertilizer and by-products. The fermentation method disclosed by the invention has the advantages of short production cycle, good product quality, simple and convenient operation process and high resource utilization value. The problems of difficulty in quality control, environmental pollution caused by the fermentation process, low fermentation efficiency and the like in traditional fermentation methods are solved.

Description

technical field [0001] The invention relates to an electromagnetic enhanced continuous fermentation method and device, that is, continuous fermentation treatment is carried out under the conditions of aeration, strong free radicals, micro voltage and magnetic field enhancement, so as to realize the rapid and efficient completion of the fermentation process of organic matter, belonging to the field of organic matter fermentation production. Background technique [0002] Ordinary fermentation technology uses the degradation of natural microorganisms to transform unstable organic matter into more stable organic matter. However, the production of natural fermentation by microorganisms takes a long time and is low in efficiency, and the process requires regular manual turning. To ensure the amount of oxygen, this method is often difficult to control the accurate content of oxygen, and it is easy to form an anoxic environment and affect the effect of aerobic fermentation.
