　　The use and management of biogas equipment

　　时必须控制空气流量，使脱硫剂床层温度稳定在60℃左右。脱硫剂的活性随再生次数逐渐下降，一般使用2～5次即更换新的脱硫剂。丝瓜视频污版生产管理丝瓜视频污版是一种易燃易爆、窒息性气体，在丝瓜视频污版生产管理中宜注意以下方面：①在丝瓜视频污版生产区、丝瓜视频污版发电室等处，禁止放置易燃、易爆物品，严禁烟火，并须备有消防设备。用气设备均有阻止回火装置（防火器），并保持良好状态。

　　It is necessary to control the air flow rate to stabilize the temperature of the desulfurizer bed at around 60 ℃. The activity of desulfurizer gradually decreases with the number of regenerations, and it is generally replaced with a new desulfurizer after 2-5 uses. Biogas production management: Biogas is a flammable, explosive, and suffocating gas. In biogas production management, attention should be paid to the following aspects: ① Flammable and explosive materials are prohibited from being placed in biogas production areas, biogas power generation rooms, etc. Smoking is strictly prohibited, and fire-fighting equipment must be prepared. All gas equipment is equipped with anti backfire devices (fire extinguishers) and maintained in good condition.

　　对验收合格的丝瓜视频污版工程设施必须进行科学使用和管理，才能充分发挥工程效益和安全运行。使用和管理主要有以下内容。

　　Scientific use and management of qualified biogas engineering facilities must be carried out in order to fully utilize engineering benefits and ensure safe operation. The use and management mainly include the following contents.

　　投产前的试运转

　　Trial operation before production

　　新建丝瓜视频污版池应灌水试压，使气压增至2940帕。如24小时内压力下降小于10%，则可认为池体密封性符合要求，否则重新采取密封措施，再按上述方法检验，直至合格为止。与丝瓜视频污版池配套的所有管道、阀门均须根据其各自的运行技术条件，分别按照设计标准进行检验。对于各种压力表和流量计，以及液面、温度、pH等指示、仪表，加热器、搅拌器、电机、水泵等设备，按各自的产品质量检验标准和设计要求进行单机调试和整个系统联动运行，使全套设备按工艺要求处于正常技术状态。

　　Newly built biogas digesters should be filled with water for pressure testing to increase the air pressure to 2940 Pa. If the pressure drop within 24 hours is less than 10%, it can be considered that the sealing of the pool meets the requirements. Otherwise, sealing measures will be taken again and the above method will be used for inspection until it is qualified. All pipelines and valves that are compatible with biogas digesters must be inspected according to their respective operating technical conditions and design standards. For various pressure gauges and flow meters, as well as indicators and instruments for liquid level, temperature, pH, heaters, mixers, motors, water pumps, and other equipment, single machine debugging and overall system linkage operation shall be carried out according to their respective product quality inspection standards and design requirements, so that the entire set of equipment is in normal technical condition according to the process requirements.

　　丝瓜视频污版发酵装置的起动

　　Start up of biogas fermentation device

　　丝瓜视频污版发酵起动期较长，若能在起动时加入大量厌氧活性污泥作为接种物就可缩短起动期。起动的生化需氧量负荷一般可在0.5～3千克COD/米3·天，待工作正常后可逐渐增加负荷，每次提高0.5～1.5千克COD/米3·天，每次提高负荷后的稳定运行时间为水力滞留期的5～10倍。在接种来源方便的地方，应一次把所需的污泥加足。起动运转阶段注意因超负荷运转而出现酸化，使甲烷化过程受到抑制。

　　The start-up period of biogas fermentation is relatively long. If a large amount of anaerobic activated sludge can be added as inoculum during start-up, the start-up period can be shortened. The starting biochemical oxygen demand load can generally be between 0.5-3 kg COD/m3 · day. After normal operation, the load can be gradually increased by 0.5-1.5 kg COD/m3 · day each time. The stable operation time after each increase in load is 5-10 times that of the hydraulic retention period. In places where vaccination sources are convenient, the required amount of sludge should be added at once. During the start-up phase, attention should be paid to the occurrence of acidification due to overload operation, which can suppress the methane conversion process.

　　丝瓜视频污版发酵工艺的生产控制

　　Production Control of Biogas Fermentation Process

　　丝瓜视频污版发酵起动后，主要通过调节所投加原料的量控制负荷，并控制温度和发酵液的pH值等以保证正常的生产过程。在实际工作中，对进料量、进料和出料的COD或浓度、产气量、气体成分，进出料的pH值及挥发酸含量进行监测。对于高浓度废料的处理，如仅测定出水的pH值，会出现滞后现象，而应在进料端设置取样点，当发现pH值出现较大变化时立即减少或停止进料，使pH值得到恢复，维持pH值在6.8以上，使丝瓜视频污版池正常运转。丝瓜视频污版产量也是很敏感的指标，在工艺条件稳定的情况下，丝瓜视频污版产量大幅度上升，可能与负荷突然提高有关，此时须注意酸化现象的产生：如果负荷未变，气体产量突然降低，此时须检查是否有有毒物质进入丝瓜视频污版池内。气体中的甲烷含量及发酵液中的挥发酸构成也可以预报可能发生的事故。在一般情况下，甲烷含量均在55%以上，挥发酸中的乙酸占95%，丙酸占5%，丁酸和戊酸则含量甚微。如果甲烷含量下降，丁酸和戊酸含量上升，这就预示设备超负荷运转，须立即采取措施防止事故发生。在日常运行过程中，注意定时打开排泥管排泥，放掉冷凝水收集器中的积水，排泥管长期不排泥会因沉砂游积而堵死，冷凝水过多会引起输气管路堵塞。

　　After the start of biogas fermentation, the load is mainly controlled by adjusting the amount of raw materials added, and the temperature and pH value of the fermentation broth are controlled to ensure the normal production process. In practical work, monitoring the feed rate, COD or concentration of feed and discharge, gas production, gas composition, pH value of feed and discharge, and volatile acid content. For the treatment of high concentration waste, if only the pH value of the effluent is measured, hysteresis may occur. Therefore, a sampling point should be set up at the feeding end. When a significant change in pH value is found, the feeding should be immediately reduced or stopped to restore the pH value and maintain it above 6.8, so that the biogas digester can operate normally. Biogas production is also a sensitive indicator. Under stable process conditions, a significant increase in biogas production may be related to a sudden increase in load. At this time, attention should be paid to the occurrence of acidification phenomenon: if the load remains unchanged and the gas production suddenly decreases, it is necessary to check whether there are toxic substances entering the biogas digester. The methane content in the gas and the composition of volatile acids in the fermentation broth can also predict possible accidents. In general, methane content is above 55%, acetic acid accounts for 95% of volatile acids, propionic acid accounts for 5%, and butyric acid and valeric acid have very low content. If the methane content decreases and the butyric acid and valeric acid content increases, it indicates that the equipment is operating at overload and immediate measures must be taken to prevent accidents from occurring. During daily operation, pay attention to opening the sludge discharge pipe regularly to drain the accumulated water in the condensate collector. If the sludge discharge pipe is not discharged for a long time, it will be blocked due to sedimentation and accumulation. Excessive condensate water can cause blockages in the gas pipeline.

　　全混消化工艺和厌氧接触工艺在运转过程中要对发酵原料进行搅拌，通过搅拌可以增加原料和微生物的接触，从而使反应速度加快，同时可防止沉淀分层现象，保持池内温度均匀，防止产生或破坏浮渣层，促进气泡的分离和逸出。搅拌的次数与强度可根据具体情况确定，悬浮固体含量浓度大的发酵原料需加强搅拌，一般每天搅拌1～3次，每次搅拌的时间长短以发酵原料达到完全混合的均一状态为准。过多的搅拌对发酵则不起作用。

　　The fully mixed digestion process and anaerobic contact process require stirring of the fermentation raw materials during operation. By stirring, the contact between the raw materials and microorganisms can be increased, thereby accelerating the reaction rate. At the same time, it can prevent sedimentation and stratification, maintain uniform temperature in the tank, prevent the formation or damage of the floating slag layer, and promote the separation and escape of bubbles. The frequency and intensity of stirring can be determined according to specific situations. Fermentation materials with high suspended solid content concentration need to be stirred more frequently, generally 1-3 times a day. The length of each stirring time is based on the fermentation materials reaching a completely mixed and uniform state. Excessive stirring has no effect on fermentation.

　　丝瓜视频污版发酵过程中需保持温度稳定，因微生物对温度有较大的敏感性，温度变化将影响产气量。对采用高中温发酵的丝瓜视频污版工程，温度变化宜控制在±3℃之内。

　　During the process of biogas fermentation, it is necessary to maintain temperature stability, as microorganisms are highly sensitive to temperature, and temperature changes will affect gas production. For biogas projects that use high and medium temperature fermentation, temperature changes should be controlled within ± 3 ℃.

　　丝瓜视频污版装置维修

　　Maintenance of biogas plant

　　分别制定所有丝瓜视频污版装置的检修周期，除临时维修外，按规定周期主要进行检修。发酵池每隔5～15年有计划地清扫检修一次，事先备好存放活性污泥的容器，以便检修后很快投产。检修时将污水、污泥浮渣和底部沉沙清扫干净，进行防腐、防渗、防漏处理，最后按规定进行合格验收后，才能重新投入污泥继续运行。

　　Develop maintenance cycles for all biogas plants separately, and except for temporary maintenance, mainly carry out maintenance according to the prescribed cycle. The fermentation tank should be cleaned and maintained in a planned manner every 5 to 15 years, and containers for storing activated sludge should be prepared in advance for quick production after maintenance. During maintenance, the sewage, sludge scum, and bottom sediment should be cleaned up, and anti-corrosion, anti-seepage, and leak proof treatment should be carried out. After passing the qualified acceptance according to regulations, the sludge can be put back into operation again.

　　脱硫剂需定时进行再生处理，当脱硫装置出口的丝瓜视频污版中硫化氢浓度超过要求指标，而脱硫剂的硫容尚未达到30%时，则需在装置内进行脱硫剂的再生处理。再生时先将脱硫装置丝瓜视频污版系统关闭，前期可将上部的放空阀和塔底的排污阀打开，利用脱硫剂再生时本身放出的热量形成空气对流，再生即由下向上逐层进行。后期用鼓风机由上口向下鼓入空气，直至进出口氧浓度基本相等为止。再生时间一般在24小时左右。再生时切忌超温，否则会导致硫升华和硫自燃，使脱硫剂失活，设备损坏。因此，再生时必须控制空气流量，使脱硫剂床层温度稳定在60℃左右。脱硫剂的活性随再生次数逐渐下降，一般使用2～5次即更换新的脱硫剂。

　　The desulfurizer needs to be regenerated regularly. When the concentration of hydrogen sulfide in the biogas at the outlet of the desulfurization device exceeds the required index and the sulfur capacity of the desulfurizer has not yet reached 30%, the desulfurizer needs to be regenerated inside the device. When regenerating, first turn off the biogas system of the desulfurization device. In the early stage, open the upper vent valve and the bottom drain valve of the tower, and use the heat released by the desulfurizer during regeneration to form air convection. Regeneration is carried out layer by layer from bottom to top. In the later stage, use a blower to blow air downwards from the upper opening until the oxygen concentration at the inlet and outlet is basically equal. The regeneration time is usually around 24 hours. During regeneration, it is important to avoid overheating as it can cause sulfur sublimation and spontaneous combustion, leading to deactivation of the desulfurizer and equipment damage. Therefore, during regeneration, it is necessary to control the air flow rate to stabilize the temperature of the desulfurizer bed at around 60 ℃. The activity of desulfurizer gradually decreases with the number of regenerations, and it is generally replaced with a new desulfurizer after 2-5 uses.
