  1. 合适的发酵温度
  1. Appropriate fermentation temperature
  蒸煮器的温度条件可分为:
  The temperature conditions of the digester can be divided into:
  1. 室温发酵(又称低温发酵)的温度范围在10℃到30℃之间。在此温度下,产气量可达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. 中温发酵温度在30℃~ 45℃之间。在此温度下,池容产气量可达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.高温发酵温度45℃~ 60℃。在此温度下,储气罐产气量可达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.
  沼气发酵经济的温度是35℃,即中温发酵。
  The economic temperature of biogas fermentation is 35 ℃, i.e. medium temperature fermentation.
  二是发酵液的适当浓度
  The second is the proper concentration of fermentation liquid
  发酵液的浓度范围为2-30%。浓度越高,产气量越大。发酵液浓度在20%以上称为干发酵。
  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.发酵材料中碳氮比例适宜(C:N)
  3. The proportion of carbon and nitrogen in fermentation materials is suitable (C: n)
  沼气发酵微生物对碳的需求量,其次是氮。我们把微生物所需的碳氮比称为碳氮比,用碳氮比表示。目前一般采用25:1,但不是很严格,20:1,25:1,30:1可以正常发酵。
  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.
  合适的ph值
  Suitable pH value
  沼气发酵适宜的PH值在PH=6.5 - 7.5之间,PH值影响酶活性,影响发酵速率。
  The pH value of biogas fermentation is between 6.5 and 7.5, which affects enzyme activity and fermentation rate.
  5. 足够数量的菌株
  5. Enough strains
  沼气发酵中细菌的数量,直接影响到沼气的产量和质量,一般要求发酵原料的液体总量为10-30%,才能保证正常启动和旺盛的沼气生产。
  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.
