　　The use and management of biogas equipment

　　時必須控製空氣流量，使脫硫劑床層溫度穩定在60℃左右。脫硫劑的活性隨再生次數逐漸下降，一般使用2～5次即更換新的脫硫劑。羞羞视频黄色软件生產管理羞羞视频黄色软件是一種易燃易爆、窒息性氣體，在羞羞视频黄色软件生產管理中宜注意以下方麵：①在羞羞视频黄色软件生產區、羞羞视频黄色软件發電室等處，禁止放置易燃、易爆物品，嚴禁煙火，並須備有消防設備。用氣設備均有阻止回火裝置（防火器），並保持良好狀態。

　　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.

　　對驗收合格的羞羞视频黄色软件工程設施必須進行科學使用和管理，才能充分發揮工程效益和安全運行。使用和管理主要有以下內容。

　　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.

　　投產前的試運轉

　　Trial operation before production

　　新建羞羞视频黄色软件池應灌水試壓，使氣壓增至2940帕。如24小時內壓力下降小於10%，則可認為池體密封性符合要求，否則重新采取密封措施，再按上述方法檢驗，直至合格為止。與羞羞视频黄色软件池配套的所有管道、閥門均須根據其各自的運行技術條件，分別按照設計標準進行檢驗。對於各種壓力表和流量計，以及液麵、溫度、pH等指示、儀表，加熱器、攪拌器、電機、水泵等設備，按各自的產品質量檢驗標準和設計要求進行單機調試和整個係統聯動運行，使全套設備按工藝要求處於正常技術狀態。

　　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.

　　羞羞视频黄色软件發酵裝置的起動

　　Start up of biogas fermentation device

　　羞羞视频黄色软件發酵起動期較長，若能在起動時加入大量厭氧活性汙泥作為接種物就可縮短起動期。起動的生化需氧量負荷一般可在0.5～3千克COD/米3·天，待工作正常後可逐漸增加負荷，每次提高0.5～1.5千克COD/米3·天，每次提高負荷後的穩定運行時間為水力滯留期的5～10倍。在接種來源方便的地方，應一次把所需的汙泥加足。起動運轉階段注意因超負荷運轉而出現酸化，使甲烷化過程受到抑製。

　　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.

　　羞羞视频黄色软件發酵工藝的生產控製

　　Production Control of Biogas Fermentation Process

　　羞羞视频黄色软件發酵起動後，主要通過調節所投加原料的量控製負荷，並控製溫度和發酵液的pH值等以保證正常的生產過程。在實際工作中，對進料量、進料和出料的COD或濃度、產氣量、氣體成分，進出料的pH值及揮發酸含量進行監測。對於高濃度廢料的處理，如僅測定出水的pH值，會出現滯後現象，而應在進料端設置取樣點，當發現pH值出現較大變化時立即減少或停止進料，使pH值得到恢複，維持pH值在6.8以上，使羞羞视频黄色软件池正常運轉。羞羞视频黄色软件產量也是很敏感的指標，在工藝條件穩定的情況下，羞羞视频黄色软件產量大幅度上升，可能與負荷突然提高有關，此時須注意酸化現象的產生：如果負荷未變，氣體產量突然降低，此時須檢查是否有有毒物質進入羞羞视频黄色软件池內。氣體中的甲烷含量及發酵液中的揮發酸構成也可以預報可能發生的事故。在一般情況下，甲烷含量均在55%以上，揮發酸中的乙酸占95%，丙酸占5%，丁酸和戊酸則含量甚微。如果甲烷含量下降，丁酸和戊酸含量上升，這就預示設備超負荷運轉，須立即采取措施防止事故發生。在日常運行過程中，注意定時打開排泥管排泥，放掉冷凝水收集器中的積水，排泥管長期不排泥會因沉砂遊積而堵死，冷凝水過多會引起輸氣管路堵塞。

　　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.

　　全混消化工藝和厭氧接觸工藝在運轉過程中要對發酵原料進行攪拌，通過攪拌可以增加原料和微生物的接觸，從而使反應速度加快，同時可防止沉澱分層現象，保持池內溫度均勻，防止產生或破壞浮渣層，促進氣泡的分離和逸出。攪拌的次數與強度可根據具體情況確定，懸浮固體含量濃度大的發酵原料需加強攪拌，一般每天攪拌1～3次，每次攪拌的時間長短以發酵原料達到完全混合的均一狀態為準。過多的攪拌對發酵則不起作用。

　　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.

　　羞羞视频黄色软件發酵過程中需保持溫度穩定，因微生物對溫度有較大的敏感性，溫度變化將影響產氣量。對采用高中溫發酵的羞羞视频黄色软件工程，溫度變化宜控製在±3℃之內。

　　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 ℃.

　　羞羞视频黄色软件裝置維修

　　Maintenance of biogas plant

　　分別製定所有羞羞视频黄色软件裝置的檢修周期，除臨時維修外，按規定周期主要進行檢修。發酵池每隔5～15年有計劃地清掃檢修一次，事先備好存放活性汙泥的容器，以便檢修後很快投產。檢修時將汙水、汙泥浮渣和底部沉沙清掃幹淨，進行防腐、防滲、防漏處理，最後按規定進行合格驗收後，才能重新投入汙泥繼續運行。

　　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.

　　脫硫劑需定時進行再生處理，當脫硫裝置出口的羞羞视频黄色软件中硫化氫濃度超過要求指標，而脫硫劑的硫容尚未達到30%時，則需在裝置內進行脫硫劑的再生處理。再生時先將脫硫裝置羞羞视频黄色软件係統關閉，前期可將上部的放空閥和塔底的排汙閥打開，利用脫硫劑再生時本身放出的熱量形成空氣對流，再生即由下向上逐層進行。後期用鼓風機由上口向下鼓入空氣，直至進出口氧濃度基本相等為止。再生時間一般在24小時左右。再生時切忌超溫，否則會導致硫升華和硫自燃，使脫硫劑失活，設備損壞。因此，再生時必須控製空氣流量，使脫硫劑床層溫度穩定在60℃左右。脫硫劑的活性隨再生次數逐漸下降，一般使用2～5次即更換新的脫硫劑。

　　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.
