沼氣池建好安裝后應于適當的管理，三分建七分管，管理很關鍵。一般沼氣池本身不漏水漏氣就沒有問題，產氣的多少完全靠管理。下面沼氣提純設備廠家給大家總結幾點沼氣池在北方地區冬季使用管理的方法，希望對大家有所幫助！
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、將沼氣池建在大棚或禽畜舍內
1. Build biogas digesters in greenhouses or livestock houses
北方地區將沼氣池建在大棚或禽畜舍內，是確保北方地區沼氣正常運行的好方法，溫室大棚或禽畜舍內，冬季也要做好保溫措施。
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、冬季增加保溫措施的幾種方法：
2. Several ways of increasing thermal insulation measures in winter:
1、直接蓋幾層農膜，雨雪或晚間再加蓋草（棉）被保溫，農膜履蓋面積大于沼氣池周邊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、日出時增加光照，日落時點沼氣燈保溫。
2. Increase illumination at sunrise and light biogas lamp at sunset to keep warm.
3、北方建沼氣池時將它與暖炕連成一體，冬季使用炕的余熱加溫，在連續陰雨天或下雪（無陽光），將炕的排煙閥開大些，使沼氣池的周邊溫度控制在>15℃、<30℃之間。
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、入冬時將半干糞便或秸稈堆蓋在沼氣池上，蓋上農膜，用糞便或秸稈的自身發熱保溫，春季氣溫回升后去掉。
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、注意事項：
3. Notes:
1、冬季不能將冰涼的原料直接進入池子，在進池前用農膜覆蓋后，在有日照連曬幾天后入池或直接用熱水拌后進入池內。盡量在入冬前大進料一次（一般為總池容的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、沼氣壓力不要太大，沼氣壓力太大進出料口沼液會溢出。
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、冬季池子周邊溫度應保持在15℃以上，加溫的沼氣池應控制在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、用地灶或蓋秸稈時應注意用火安全。
4. Fire safety should be paid attention to when using stove or covering straw.
5、用沼氣燈增溫時，應將大棚拱高些（一般在2米左右）。
5. When heating with biogas lamp, the greenhouse arch should be higher (generally about 2 meters).
6、應注意流入池內的液體溫度盡量大于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、濃度應保持在6% ～ 10%（干物質）。
7. Concentration should be maintained at 6%-10%(dry matter).
8、15℃以下時盡量不要去掉農膜進出料，一般在中午氣溫回升時進出料，進出料后應及時蓋好。
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值應保持在中性為佳。
9. PH value should be kept neutral.
