气池建成后,日常的管理好坏对沼气的产生及运用影响很大。沼气池建立“三分在建池,七分在管理”。沼气池建好是产气的根底,但沼气池的运用管理却是沼气池运转的关键。
After the completion of the gas pool, the daily management has a great impact on the production and application of biogas. The biogas digester is to be built in three parts and managed in seven parts. The construction of biogas digester is the foundation of gas production, but the application and management of biogas digester is the key to the efficient operation of biogas digester.
(1)及时补充新原料,确坚持续产沼气。有些沼气池在运用段时间后(2~3个月后),会呈现不产气或产气少或产气但点不着火的现象,这可能是发酵原料耗费完了,这时应思索补充新料。补充新料时间控制在新沼气池正常产气后1.5~2个月时停止,新原料补充宜逐步、持续投人,不可一次投入过多。
(1) timely supplement new raw materials to ensure continuous biogas production. After some biogas digesters are used for a period of time (2-3 months later), there will be no gas production or less gas production or gas production but no ignition, which may be due to the consumption of fermentation raw materials. At this time, it is necessary to consider adding new materials. The time of adding new materials shall be controlled to stop 1.5-2 months after the normal gas production of the new biogas digester, and the new materials shall be added gradually and continuously, without excessive input at one time.
(2)坚持稳定的养殖量,是好的原料补充源。一座10立方米的沼气池,要想取得持续稳定的产气量,坚持3~5头猪(或1~3头成牛)的养殖量为好,这即可保证充足的粪源供给,持续运用沼气,又能靠养殖増加家庭收入。
(2) it is the best supplement source of raw materials to maintain stable breeding quantity. If a 10 cubic meter biogas digester wants to achieve sustained and stable gas production, it is the best to maintain the breeding capacity of 3-5 pigs (or 1-3 adult cows), which can ensure adequate supply of manure sources, continue to use biogas, and increase family income by breeding.
(3)勤进、勤出、勤搅动,可大大进步产气量。为保证沼气池能正常、稳定产生大量沼气,就要做到勤进料、勤出料。这既可保证有充足的发酵原料又有以下几点益处:一是与定期大换料相比,不会形成大量沼气菌的流失。二是对沼气池内料液的温度影响较小。三是对池内沼气压力变化影响小,不会呈现大换料后断气现象。四是对池内料液酸碱度影响较小,有利于沼气发酵稳定停止。勤搅动能够使沼气池内料液的浓度、温度、酸碱度坚持分歧;能够使发酵原料与沼气菌充沛混合接触,进步转换率;能够加快沼气向外扩散的速度,进步产气量。能够突破原料浮壳层,有利沼气释放。勤进、勤出、勤搅动均匀产气量可进步50%以上。
(3) frequent in, out and agitation can greatly improve gas production. In order to ensure the normal and stable production of a large amount of biogas in the biogas digester, it is necessary to feed and discharge materials frequently. This not only ensures that there are sufficient fermentation materials, but also has the following benefits: first, compared with regular large refueling, it will not form a large number of loss of biogas bacteria. Second, it has little effect on the temperature of the feed liquid in the biogas digester. Third, it has little effect on the change of biogas pressure in the tank and will not show the phenomenon of gas cut-off after large refueling. Fourth, it has little effect on the pH value of feed liquid in the tank, which is conducive to the stable stop of biogas fermentation. Frequent agitation can make the concentration, temperature and pH value of the feed liquid in the biogas digester stick to differences; it can make the fermentation raw materials and biogas bacteria fully mix and contact, improve the conversion rate; it can speed up the outward diffusion of biogas, and improve the gas production. It can break through the floating shell of raw materials and facilitate the release of biogas. More than 50% of the average gas production can be improved by frequent input, frequent output and frequent agitation.
(4)冬季保暖是沼气池终年运用的关键。冬季气温、地温较低,特别是地温对沼气池产气量影响尤为明显,据多年调查理解,以3~4月份产气少,以是不产气,所以,对冬季和早春季的沼气池停止保温是沼气池终年运用的关键。
(4) keeping warm in winter is the key to the annual operation of biogas digesters. In winter, the temperature and ground temperature are relatively low, especially the ground temperature has an obvious impact on the gas production of biogas digesters. According to the investigation for many years, the gas production is the least from March to April, even the gas production is not. Therefore, the key to the annual operation of Biogas digesters is to stop the heat preservation of biogas digesters in winter and early spring.
①沼气池建造时宜先在背风、向阳、地温较高的。有条件的可建在日光温室大棚内。没条件的也要建在冻土层以下。冬季池上堆盖秸秆、杂草、锯末等作为保温资料。
① the biogas digester should be built in the center of leeward, sunny and high ground temperature. If possible, it can be built in a greenhouse. It should also be built under the permafrost. In winter, straw, weeds and sawdust are piled on the pond as heat preservation materials.
②沼气池好建在畜禽圈舍下方,在做好圈舍保温的同时也确保了沼气池的保温。
② the biogas digester is best built under the livestock and poultry enclosure, which ensures the insulation of the biogas digester at the same time.
③冬季和早春时节补充原料时好添加热水,以进步发酵原料和池内的温度。
③ it is better to add hot water when replenishing raw materials in winter and early spring to improve the temperature of fermentation raw materials and pool.
④要及时补充发酵原料,进步料液浓度。但不宣添加粘、杂草等含碳素高的原料作为补充。
④ the raw materials for fermentation should be supplemented in time to improve the concentration of feed solution. However, it is not recommended to add raw materials with high carbon content such as sticky and weeds as supplements.
⑤要勤搅动,低温条件下沼气池易结売、分层,需求增强搅动。普通每3~4天搅动一次为好,可自制搅拌器从进料口伸入池内搅动,也可应用沼液回流搅动(即用水桶从水压间内取出一定沼液后从进料口倒入池内)。
⑤ frequent agitation is required. At low temperature, the biogas digester is easy to form and stratified, and the demand is increased. Generally, it is better to agitate once every 3-4 days. The self-made agitator can be extended into the tank from the feed port for agitation, or the biogas slurry can be used for backflow agitation (that is, take a certain amount of biogas slurry out of the water pressure room with a bucket and then pour it into the tank from the feed port).
