Difference between Hydrolytic Acidification and Anaerobic

In the chemical industry, the treatment of organic matter is a complex and important task. Both hydrolytic acidification and anaerobic fermentation are commonly used organic matter treatment processes. Due to the significant differences in mechanism, application range and treatment effect, it is the key to choose the appropriate process. This paper will analyze the difference between hydrolysis acidification and anaerobic fermentation in depth to help chemical workers make scientific decisions.

Hydrolytic acidification: a biochemical process

Hydrolytic Acidification Basic Concepts

Hydrolytic acidification is an organic matter treatment process based on biodegradation, which mainly uses the biochemical action of microorganisms to decompose organic matter into simpler substances. Its core is the use of hydrolytic bacteria to convert high molecular organic matter into soluble substances, followed by acidification to further remove impurities.

The biochemical reaction process

The biochemical reaction of hydrolysis acidification mainly includes the following stages:

1. Hydrolysis stage: hydrolysis bacteria polyethylene and other high molecular organic decomposition into monomer substances, such as ethylene and methanol.
2. Reduction stage: through specific microorganisms, the decomposed products are further reduced to carbon dioxide and methane.
3. Acidification: the use of acidic conditions, the removal of decomposition process by-products, to ensure the system stable operation.

Hydrolytic Acidification Applicable Scenarios

The hydrolysis acidification process is suitable for the treatment of high concentration organic environment, such as waste treatment in polyethylene production. It is characterized by good treatment effect and can achieve the goal of complete recycling.

Anaerobic Fermentation: Biodegradation of Organic Matter

Anaerobic Fermentation Basic Concepts

Anaerobic fermentation is an anaerobic fermentation process that uses aerobic microorganisms to decompose organic matter into carbon dioxide and methane. Its core is the gradual decomposition of complex organic matter through the activities of microorganisms.

anaerobic fermentation reaction mechanism

The reaction mechanism of anaerobic fermentation mainly includes the following steps:

1. Decomposition: Aerobic microorganisms decompose organic matter into carbon dioxide and methane Deleting methane.
2. Stable stage: by adjusting the temperature and pH value, to ensure the fermentation process stability and safety.

Anaerobic Fermentation Applicable Scenarios

Anaerobic fermentation process is suitable for the treatment of low concentration organic matter environment, such as swill treatment in catering industry. It is characterized by a mild treatment process and is not easy to produce secondary pollution.

Hydrolytic Acidification and Anaerobic Fermentation

Same point

1. Biodegradation mechanism: both use microbial biodegradation, through different reaction mechanisms to deal with organic matter.
The
2. goals are the same: both aim to reduce organic content and improve environmental friendliness.

difference point

1. Applicable concentration: hydrolysis acidification is suitable for high concentration of organic matter environment, while anaerobic fermentation is suitable for low concentration environment.
2. Reaction Phase: Hydrolytic acidification comprises an acidification phase, while anaerobic fermentation is entirely dependent on microbial activity.
3. Treatment: Hydrolytic acidification can more thoroughly decompose organic matter and achieve completely recyclable goals.

Select Recommendations

When selecting an organic treatment process, trade-offs should be made based on specific environmental conditions and treatment objectives:

1. High concentration of organic matter: give priority to the hydrolysis acidification process.
2. Low concentration organic: can choose anaerobic fermentation process.
3. Special requirements: according to the specific processing objectives and economy, flexible choice of process combination.

Conclusion

Hydrolysis acidification and anaerobic fermentation are commonly used organic matter treatment processes in the chemical industry, and both have their own advantages and disadvantages. Choosing the right process can not only improve the processing efficiency, but also create favorable conditions for the subsequent recycling of resources. Chemical workers need to be based on actual needs, scientific analysis, reasonable selection, in order to achieve efficient treatment of organic matter and sustainable use of resources.
