沼气池建成以后如果原料投放不当,则易造成产气缓慢或产气点不着火,甚至不产气的现象。因此,新建成的沼气池首次投料时应注意以下几方面:一、原料堆沤原料在入池前先堆沤一段时间,促其腐熟。若气温高,堆沤时间为2～3天;气温低堆沤时间则需4～5天。原料的腐熟程度也可通过直观判断,如果原料的颜色加深、气味浓厚、不断渗出褐色 Biogas digesters built if the improper delivery of raw materials, it is easy to cause slow gas production or gas point does not catch fire, or even gas phenomenon. Therefore, the newly built biogas digester for the first time should pay attention to the following aspects: First, the raw materials 沤 沤 raw materials into the pool before the reactor for some time, to promote its maturity. If the temperature is high, the pounding time is 2 to 3 days; the temperature is low piling time is 4 to 5 days. The degree of maturity of raw materials can also be intuitively judged, if the color of raw materials deepen, strong smell, constantly seeping brown
