Abstract

The invention discloses a cold-region methane accelerator and a preparation method of the cold-region methane accelerator and relates to a methane accelerator and a preparation method of the methane accelerator. The invention aims at solving the technical problems that the existing methane accelerators can not improve gas production rate at low temperature and are difficult to obtain. The cold-region methane accelerator provided by the invention comprises ferrum, cobalt, nickel, organic matters, an adsorbent and a filler. The preparation method comprises the following steps that: (1) ferrous sulfate, cobalt chloride, nickel chloride, the organic matters, the adsorbent and the filler are weighed; (2) distilled water is added to the weighed ferrous sulfate, cobalt chloride and nickel chloride to prepare saturated solution; the adsorbent is added; a crusher is used for crushing after drying to obtain powder; and (3) the organic matters and the filler are added to the powder and the mixture is evenly mixed to obtain the cold-region methane accelerator. The methane accelerator and the preparation method are applicable to the methane field.

Description

technical field [0001] The invention relates to a biogas accelerator and a preparation method thereof. Background technique [0002] Due to the low annual average temperature of biogas production in cold regions, the fermentation effect is not ideal, and the gas production rate is low, below 1:0.3, and the gas production time is short, which seriously limits the development of biogas in cold regions. There are three types of biogas accelerators. The first type is to improve the nutritional status of fermenting microorganisms and meet their nutritional needs. For example, leftovers from tofu factories, wine factories, and powder factories can be added to biogas digesters to increase the temperature of the pond and increase production. Gas volume; the second category provides fermenting microorganisms with trace element substances that promote growth and reproduction, such as peat and old batteries; the third category is substances that improve and stabilize the living environ...
