What are the advantages of dry anaerobic digestion technology? STRABAG manufacturers to introduce for you!
According to the STRABAG manufacturer, under anaerobic conditions, the method of using natural microorganisms or inoculated microorganisms to convert organic matter into carbon dioxide and methane gas is called anaerobic digestion treatment. This method has the advantages of low energy consumption, less residual sludge and energy recovery. In recent years, dry anaerobic digestion technology has been actively developed and applied in developed countries, especially in Europe, and will become one of the directions of organic solid waste treatment in the future.

Some knowledge of dry anaerobic, STRABAG manufacturers tell you
STRABAG manufacturers believe that kitchen waste, as the main urban organic solid waste, has caused tremendous pressure on society and the environment. Its characteristics of high water content, high organic matter and easy degradation are very suitable for anaerobic fermentation. Compared with the traditional wet fermentation, dry anaerobic fermentation is more suitable for treating a large amount of food waste. However, in the process of dry anaerobic fermentation of kitchen waste, there are problems such as volatile fatty acid (VFA) accumulation, difficult stirring and poor mass transfer, which affect the stability and gas production efficiency of the system.

Dry anaerobic fermentation principle and characteristics, STRABAG manufacturers to explain for you
STRABAG manufacturers believe that kitchen waste refers to the garbage generated by residents in daily life, food processing, kitchen services, unit meals and other activities, including household kitchen waste, kitchen waste and other kitchen waste. It has the characteristics of high water content and high organic matter content, which is perishable and produces stench, threatening the urban living environment and residents' health.

Dry anaerobic fermentation process and characteristics, STRABAG manufacturers for you to dispel doubts
STRABAG manufacturers believe that under anaerobic conditions, the use of natural microorganisms or inoculated microorganisms to convert organic matter into carbon dioxide and methane gas is called anaerobic digestion. This method has the advantages of low energy consumption, less residual sludge and energy recovery. In recent years, dry anaerobic digestion technology has been actively developed and applied in developed countries, especially in Europe, and will become one of the directions of organic solid waste treatment in the future.

What are the characteristics of dry anaerobic process
The dry anaerobic process starts from feeding, which is to mix the organic part of the kitchen waste pretreatment with the solid residue part separated from the three phases of the kitchen waste, and then transport it to the dry anaerobic tank through the metering and conveying system. The capacity of a single tank to treat organic matter is 110 tons/day. After 22 days of anaerobic fermentation in the tank, the organic waste is transported to the subsequent dewatering system through the vacuum discharge system.

The role and characteristics of dry anaerobic equipment
In recent years, with the implementation of the compulsory classification policy of domestic waste and the promotion of the four-division classification method, kitchen waste will be treated separately and resourced, and the dry anaerobic comprehensive treatment of kitchen waste will gradually become the mainstream technology. At present, the development and application of dry anaerobic technology in foreign countries have been very mature, but the application of dry anaerobic technology independently developed in China in large-scale industrial projects is still rare.

Some Common Sense of Dry Anaerobic Fermentation
Dry anaerobic fermentation refers to a complex biochemical reaction process in which a variety of microorganisms work together to degrade organic matter and produce methane and carbon dioxide under anaerobic conditions. Compared with other treatment methods, anaerobic fermentation has obvious advantages. Anaerobic fermentation has the characteristics of high treatment efficiency, strong impact resistance, low energy consumption and biogas production, which can meet the urgent needs of energy saving, emission reduction and environmental protection.

What are the advantages of dry anaerobic digestion technology?
As the main component of urban organic domestic waste, it has the characteristics of high moisture, high oil, high salt, perishable and biodegradable. Direct landing is appropriate. At present, the treatment of kitchen waste is mainly based on resource utilization, such as feed, aerobic composting, anaerobic digestion and biogas recovery.

What are the main factors affecting the dry anaerobic fermentation process?
The amount of gas produced, the stability of operation and the level of CH4 content are closely related to the control of process conditions in the fermentation process. Due to the high dry material concentration of fermentation materials, problems such as difficulty in production, uneven heat transfer quality, and acidosis have become technical difficulties in dry anaerobic fermentation technology. They conducted in-depth research at home and abroad. The main factors that affect the stable operation of dry anaerobic fermentation include: substrate composition, substrate pretreatment, inoculation amount, organic load, pH value and temperature, and stirring.
