1. Appropriate 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)的溫度范圍在10℃到30℃之間。在此溫度下，產氣量可達0.15-0.3m3/m3.d

　　1. 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 tank can reach about 1m3 / m3. D.

　　3.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. High temperature fermentation temperature 45 ℃ ~ 60 ℃. At this temperature, the gas production of gas storage tank can reach 2-2.5m3/m3.

　　沼氣發酵經濟的溫度是35℃，即中溫發酵。

　　The economic temperature of biogas fermentation is 35 ℃, i.e. medium temperature fermentation.

　　二是發酵液的適當濃度

　　The second is the proper concentration of fermentation liquid

　　發酵液的濃度范圍為2-30%。濃度越高，產氣量越大。發酵液濃度在20%以上稱為干發酵。

　　The concentration range of fermentation broth is 2-30%. The higher the concentration, the greater the gas production. When the concentration of fermentation liquid is more than 20%, it is called dry fermentation.

　　3.發酵材料中碳氮比例適宜(C:N)

　　3. The proportion of carbon and nitrogen in fermentation materials is suitable (C: n)

　　沼氣發酵微生物對碳的需求量，其次是氮。我們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。

　　Biogas fermentation microorganism needs the most carbon, followed by nitrogen. We call the ratio of carbon to nitrogen required by microorganisms as the ratio of carbon to nitrogen, which is expressed as the ratio of carbon to nitrogen. At present, 25:1 is generally used, but it is not very strict. 20:1, 25:1, 30:1 can be fermented normally.

　　合適的ph值

　　Suitable pH value

　　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 pH value of biogas fermentation is between 6.5 and 7.5, which affects enzyme activity and fermentation rate.

　　5. 足夠數量的菌株

　　5. Enough 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 quantity of bacteria in biogas fermentation directly affects the output and quality of biogas. Generally, the total amount of liquid in fermentation raw materials is required to be 10-30% to ensure the normal start-up and vigorous biogas production.
