After the construction and installation of the biogas digester, proper management should be carried out, with three parts and seven branches. Management is the key. Generally, there is no problem if the biogas digester itself does not leak and leak, and the amount of gas produced depends entirely on management. The following biogas purification equipment manufacturers to summarize a few biogas digesters in northern winter use and management methods, I hope to help you!

一、将沼气池建在大棚或禽畜舍内

1. Build biogas digesters in greenhouses or livestock houses

北方地区将沼气池建在大棚或禽畜舍内，是确保北方地区沼气正常运行的好方法，温室大棚或禽畜舍内，冬季也要做好保温措施。

The best way to ensure the normal operation of biogas in the north is to build biogas digesters in greenhouses or livestock houses. In the greenhouses or livestock houses, thermal insulation measures should also be taken in winter.

二、冬季增加保温措施的几种方法：

2. Several ways of increasing thermal insulation measures in winter:

1、直接盖几层农膜，雨雪或晚间再加盖草（棉）被保温，农膜履盖面积大于沼气池周边2米以上。

1. Cover several layers of agricultural film directly. Rain and snow or cover grass (cotton) in the evening. The covering area of agricultural film is more than 2 meters around the biogas digester.

2、日出时增加光照，日落时点沼气灯保温。

2. Increase illumination at sunrise and light biogas lamp at sunset to keep warm.

3、北方建沼气池时将它与暖炕连成一体，冬季使用炕的余热加温，在连续阴雨天或下雪（无阳光），将炕的排烟阀开大些，使沼气池的周边温度控制在>15℃、<30℃之间。

3. When building biogas digester in the north, it is connected with the warm kang. In winter, the waste heat of the Kang is used to heat the digester. In continuous rainy or snowy days (without sunshine), the smoke exhaust valve of the Kang is opened larger, so that the surrounding temperature of the digester is controlled between > 15 (?) and < 30 (?).

4、入冬时将半干粪便或秸秆堆盖在沼气池上，盖上农膜，用粪便或秸秆的自身发热保温，春季气温回升后去掉。

4. When winter comes, half-dry manure or straw will be piled on the biogas digester, covered with agricultural film, feces or straw will be used to heat themselves, and the temperature will rise in spring and be removed,

三、注意事项：

3. Notes:

1、冬季不能将冰凉的原料直接进入池子，在进池前用农膜覆盖后，在有日照连晒几天后入池或直接用热水拌后进入池内。尽量在入冬前大进料一次（一般为总池容的2/3）。

1. Cold raw materials can not be directly into the pond in winter. After being covered with agricultural film before entering the pond, they can be directly mixed with hot water or sunshine for several days before entering the pond. Feed as much as possible before winter (usually 2/3 of the total tank capacity).

2、沼气压力不要太大，沼气压力太大进出料口沼液会溢出。

2. The pressure of biogas should not be too high. If the pressure of biogas is too high, the biogas slurry will overflow at the inlet and outlet.

3、冬季池子周边温度应保持在15℃以上，加温的沼气池应控制在30℃左右佳。

3. In winter, the temperature around the digester should be kept above 15 C, and the optimum temperature of the heated digester should be controlled at about 30 C.

4、用地灶或盖秸秆时应注意用火安全。

4. Fire safety should be paid attention to when using stove or covering straw.

5、用沼气灯增温时，应将大棚拱高些（一般在2米左右）。

5. When heating with biogas lamp, the greenhouse arch should be higher (generally about 2 meters).

6、应注意流入池内的液体温度尽量大于15℃以上。

6. Attention should be paid to the temperature of the liquid flowing into the tank as far as possible, which is higher than 15 degrees Celsius.

7、浓度应保持在6% ～ 10%（干物质）。

7. Concentration should be maintained at 6%-10%(dry matter).

8、15℃以下时尽量不要去掉农膜进出料，一般在中午气温回升时进出料，进出料后应及时盖好。

When the temperature is below 8 and 15 C, try not to remove the agricultural film. Generally, when the temperature rises at noon, the film should be covered in time.

9、PH值应保持在中性为佳。

9. PH value should be kept neutral.
