1春、夏季管理勤检查、勤维修上年正常运行的老沼气池,春季在运行时,首先要先检查一下沼气池体有无受冻。如发现冻裂、冻烂的池子,要及时修复,发现冻裂、冻坏的零部件要及时更换。其次检查压力表。当池内压力过大时,应及时用气、放气,以免较大压力长时间作用于沼气池,对池体造成破坏。再次检查输气管道。如果输气管道、开关的各接头部位有发黑现象,就表示沼气池漏气,应对管路进行维修。雨季,埋在地下的管道常有积水,可在离导气管1米左右的地方安装一个凝水器,以防止积水堵塞管道。勤进料、勤出料①勤进料。在常温情况下,发酵原料中有机质易被微生物分解,只需80～120天就被消耗掉。特别是人蓄粪便,有利用价值的产气时间为60～80天,而且前20天所产沼气占总产气量的30%～40%。因此,投料启动后,只有经常不断地补充新鲜原料,才能保证沼气池产气旺盛均衡。②勤出料。被沼气微生物发酵分解后的剩余物(沼渣、沼液)是优质的有机肥料,要随时从出料间取出。
1 spring and summer management ground inspection, ground maintenance last year normal operation of old biogas digesters, spring in operation, we must first check whether the digester body is frozen. Found frozen cracked, frozen rotten ponds, to be promptly repaired and found frozen cracking, frozen parts to be replaced promptly. Second check the pressure gauge. When the pressure in the tank is too large, it should be timely gas, deflate, so as not to exert greater pressure on the digester for a long time, causing damage to the pool body. Check the gas pipeline again. If the gas pipeline, the switch parts of the joints black phenomenon, it means that digesters leak, the pipeline should be repaired. Rainy season, buried in the underground pipe often have water, can be about 1 meter away from the air duct to install a water trap to prevent accumulation of water blocking the pipeline. Qin feed, ground discharge ① ground feed. In the case of normal temperature, the organic matter in the fermentation raw material is easily decomposed by the microorganism, it takes only 80 to 120 days to be consumed. In particular, man-made manure, gas production time with useful value of 60 to 80 days, and the first 20 days of biogas produced by the total gas production 30% to 40%. Therefore, feeding start, only constantly constantly add fresh raw materials, in order to ensure strong gas production biogas digesters balanced. ② hard to discharge. Biogas fermentation was decomposed residue (biogas residue, biogas slurry) is a high-quality organic fertilizer, to be removed from the discharge at any time.
