There are many industries in which biogas generators are used, such as aquaculture, food wastewater treatment, and kitchen waste treatment. Biogas combustion power generation is a biogas utilization technology that has emerged with the continuous development of large-scale biogas digesters and comprehensive utilization of biogas. It uses the biogas generated by anaerobic fermentation treatment on the engine and is equipped with a comprehensive power generation device to generate electricity and heat energy. Biogas power generation has the characteristics of efficiency creation, energy conservation, and environmental protection, and is a widely distributed and cost-effective distributed energy source. Basic conditions for biogas fermentation process of biogas generator units

一、 合適的發酵溫度

1、 Suitable fermentation temperature

蒸煮器的溫度條件可分為:

The temperature conditions of the digester can be divided into:

1. 室溫發酵(又稱低溫發酵)的溫度範圍在10℃到30℃之間。在此溫度下，產氣量可達0.15-0.3m3/m3.d

The temperature range of room temperature fermentation (also known as low-temperature fermentation) is between 10 ℃ and 30 ℃. At this temperature, the gas production can reach 0.15-0.3m3/m3. d

2. 中溫發酵溫度在30℃~ 45℃之間。在此溫度下，池容產氣量可達1m3/m3.d左右。

2. The medium temperature fermentation temperature is between 30 ℃ and 45 ℃. At this temperature, the gas production capacity of the pool can reach about 1m3/m3. d.

3.沼氣好色先生在线观看沼氣高溫發酵溫度45℃~ 60℃。在此溫度下，儲氣罐產氣量可達2-2.5m3/m3。

3. The high-temperature fermentation temperature of biogas generator set is 45 ℃~60 ℃. At this temperature, the gas production capacity of the gas storage tank can reach 2-2.5m3/m3.

沼氣好色先生在线观看沼氣發酵經濟的溫度是35℃，即中溫發酵。

The economic temperature for biogas fermentation in biogas generator units is 35 ℃, which is medium temperature fermentation.

二、發酵液的適當濃度

2、 Appropriate concentration of fermentation broth

沼氣好色先生在线观看沼氣發酵液的濃度範圍為2-30%。濃度越高，產氣量越大。發酵液濃度在20%以上稱為幹發酵。

The concentration range of biogas fermentation liquid for biogas generator units is 2-30%. The higher the concentration, the greater the gas production. Fermentation broth with a concentration above 20% is called dry fermentation.

三、發酵材料中碳氮比例適宜(C:N)

3、 Suitable ratio of carbon and nitrogen in fermentation materials (C: N)

沼氣發酵微生物對碳的需求量，其次是氮。好色TV下载安装把微生物所需的碳氮比稱為碳氮比，用碳氮比表示。目前一般采用25:1，但不是很嚴格，20:1,25:1,30:1可以正常發酵。

The demand for carbon by biogas fermentation microorganisms is followed by nitrogen. We refer to the carbon to nitrogen ratio required by microorganisms as the carbon to nitrogen ratio, which is represented by the carbon to nitrogen ratio. At present, 25:1 is generally used, but it is not very strict. 20:1, 25:1, and 30:1 can ferment normally.

合適的ph值 沼氣發酵適宜的PH值在PH=6.5 - 7.5之間，PH值影響酶活性，影響發酵速率。

The appropriate pH value for biogas fermentation is between pH=6.5-7.5, which affects enzyme activity and fermentation rate.

四、足夠數量的菌株

4、 Sufficient number of strains

沼氣發酵中細菌的數量，直接影響到沼氣的產量和質量，一般要求發酵原料的液體總量為10-30%，才能保證正常啟動和旺盛的沼氣生產。

The number of bacteria in biogas fermentation directly affects the yield and quality of biogas. Generally, the total liquid content of fermentation raw materials is required to be 10-30% to ensure normal start-up and vigorous biogas production.
