为保证冬季正常产气运行,在入冬前做好以下工作;1、入冬前沼气池要彻底换料一次,加足新料,在加料时可提高发酵料液浓度,将料液浓度提高到10%~15%。2、做好沼气池的保温工作。“一池三改”的沼气池要及早在圈舍上覆盖塑料薄膜,形成太阳能暖圈,一方面促进畜禽的生长,另一方面有利于沼气池的安全越冬。对于不是“一池三改”的沼气池,可在沼气池进料口上覆盖稻草、秸秆或干土等保温材料。
In order to ensure the normal operation of gas production in winter, do the following work before winter: 1, before the winter biogas digesters should be thoroughly refueled once, add enough new material, feeding can increase the concentration of fermented feed, the feed concentration increased To 10% to 15%. 2, good digester insulation work. “A pool of three change ” biogas digesters should be covered early in the pens on plastic film, the formation of solar warm circle, on the one hand to promote the growth of livestock and poultry, on the other hand is conducive to the safety of biogas overwintering. For not a “a pool of three changes ” digesters, biogas digesters can be covered with straw, straw or dry soil and other insulation materials.
