  在人们的使用中发现,在甲烷的储存和利用中,气罐升降频繁,有时升降过快(湿罐上升速度1。(2m/min)导致湿式储气罐维护频繁,且由于酸性气体溶于水中的甲烷,导致储气罐腐蚀,导致使用寿命缩短,给生产造成很大损失,因此有必要考虑对甲烷储气罐进行维护。
  It is found in people's use that in the storage and utilization of methane, the air tank rises and falls frequently, sometimes too fast (the rising speed of wet tank is 1. (2m / min) results in frequent maintenance of wet gas storage tank, and corrosion of gas storage tank caused by acid gas dissolving in water, which shortens service life and causes great loss to production. Therefore, it is necessary to consider the maintenance of methane gas storage tank.
  为了确保甲烷对所有点的连续供应,甚至在污水处理厂中,甲烷存储设备应设置在系统平衡甲烷流量,和甲烷气体罐的体积应该计算和确定根据天然气生产和利用率。
  In order to ensure the continuous supply of methane to all points, even in the sewage treatment plant, the methane storage equipment shall be set in the system to balance the methane flow, and the volume of methane gas tank shall be calculated and determined according to the natural gas production and utilization rate.
  (1)甲烷的来源和组成。
  (1) Source and composition of methane.
  污水处理厂的废水约70%为工业废水,约30%为生活污水。水质比较复杂。污水处理厂采用AB法处理,其特点是剩余污泥量大。A、B两块剩余污泥混合后进入浓缩池浓缩,然后进行厌氧消化,城市污水处理厂污泥主要由三种有机物质,如碳水化合物、脂肪、蛋白质、沼气产生的污泥量不同的组件,以及甲烷含量是不同的,根据废水中有机物的组成

  About 70% of the wastewater from the sewage treatment plant is industrial wastewater, and about 30% is domestic sewage. The water quality is complex. The wastewater treatment plant adopts AB process, which is characterized by a large amount of excess sludge. A. B. the two pieces of excess sludge are mixed and concentrated in the thickener, and then anaerobic digestion is carried out. The sludge of the urban sewage treatment plant is mainly composed of three kinds of organic substances, such as carbohydrate, fat, protein, components with different sludge volume generated by biogas, and different methane content. According to the composition of organic substances in the wastewater
  厌氧消化过程中产生的甲烷经过滤脱硫后进入沼气池,在稳定的运行条件下,污泥消化池甲烷含量可达55%~60%。
  The methane produced in the anaerobic digestion process is filtered and desulfurized and then enters the biogas digester. Under the stable operation conditions, the methane content in the sludge digester can reach 55% ~ 60%.
  (2)沼气的内外环境。
  (2) The internal and external environment of biogas.
  甲烷气罐中的水箱充满了水,水面以上是甲烷。因此,溶于水的气体组分在水表面形成动态平衡,CO2和H2S的溶解度高,在水中的浓度高。
  The water tank in the methane gas tank is full of water, and above the water surface is methane. Therefore, the gas components dissolved in water form a dynamic equilibrium on the water surface. The solubility of CO2 and H2S is high, and the concentration in water is high.
