一、維護與防范措施：
1、 Maintenance and preventive measures:
1、檢查循環泵：
1. Check the circulating pump:
沼氣脫硫設備系統正常運行后，定期巡視系統，保障脫硫泵和再生泵工作正常。
After the biogas desulfurization equipment system operates normally, the system shall be inspected regularly to ensure that the desulfurization pump and regeneration pump work normally.
2、檢查溢流：
2. Check overflow:
根據相關溢流流量，保障硫磺泡沫排放良好（砂的溢流表明再生塔中的鼓泡方式不能及時排放，影響脫硫效果；溢流流量過大容易干擾廢液罐中的硫磺沉積，不利于硫磺沉淀和分離）。
According to the relevant overflow flow, ensure that the sulfur foam is discharged well (the overflow of sand indicates that the bubbling mode in the regeneration tower cannot be discharged in time, affecting the desulfurization effect; the excessive overflow flow easily interferes with the sulfur deposition in the waste liquid tank, which is not conducive to the sulfur precipitation and separation).
3、排水：
3. Drainage:
脫硫塔后的分離器和過濾器應每小時定期排水，以保障沼氣不會攜帶大量水進入裝置和H2S檢測器。
The separator and filter behind the desulfurization tower shall be drained regularly every hour to ensure that biogas will not carry a large amount of water into the unit and H2S detector.
4、檢查H2S探測器：
4. Check H2S detector:
定期檢查H2S檢測器氣體管道（入口管和出口管）的堵塞情況，保障管道暢通，以便準確檢測脫硫后沼氣中的H2S含量。
Regularly check the blockage of the gas pipeline (inlet pipe and outlet pipe) of the H2S detector to ensure that the pipeline is unblocked so as to accurately detect the H2S content in the biogas after desulfurization.
5、管道檢查：
5. Pipeline inspection:
沼氣脫硫設備系統停止正常運行后，定期檢查所有管道和法蘭連接，保障無氣體和液體泄漏。
After the biogas desulfurization equipment system stops normal operation, regularly check all pipelines and flange connections to ensure that there is no gas and liquid leakage.
6、硫磺泡沫清洗：
6. Sulfur foam cleaning:
定期清理廢液罐中積累的硫磺，避免硫磺沉積過多，導致液體溢出到循環液中，導致脫硫效率下降。
Regularly clean up the sulfur accumulated in the waste liquid tank to avoid excessive sulfur deposition, which will cause the liquid to overflow into the circulating liquid and reduce the desulfurization efficiency.
7、做好值班記錄：
7. Keep duty records:
每次檢查或操作后，應仔細填寫值班記錄表。如果設備有問題，須在離開前解釋清楚。
After each inspection or operation, carefully fill in the duty record form. If there is any problem with the equipment, please explain clearly before leaving.
二、故障判斷與處理：
2、 Fault diagnosis and treatment:
對于沼氣脫硫設備系統運行中可能出現的一些常見故障及相應的處理方法，請參考以下內容：
For some common faults that may occur during the operation of biogas desulfurization equipment system and the corresponding treatment methods, please refer to the following contents:
1、H2S檢測器讀數長期保持不變，無法實現自動加堿：
1. The reading of H2S detector remains unchanged for a long time, and automatic alkali dosing cannot be realized:
原因分析及處理方法：
Cause analysis and treatment method:
（1）H2S探測器的氣管線堵塞，清洗干凈。（2）如果儀器損壞，請更換。
(1) The gas pipeline of H2S detector is blocked and cleaned. (2) If the instrument is damaged, please replace it.
2、H2S檢測儀讀數低于較大報警值，電磁閥仍處于開加堿狀態：
2. The reading of H2S detector is lower than the larger alarm value, and the solenoid valve is still in the open alkali adding state:
原因分析及處理方法：
Cause analysis and treatment method:
如果電磁閥卡住，應及時清理。
If the solenoid valve is stuck, it should be cleaned in time.
3、沼氣脫硫設備噴射器的反向噴射：
3. Reverse injection of ejector of biogas desulfurization equipment:
（1）如果噴油器尾管堵塞，應及時清理。（2）再生泵、管路堵塞，噴射壓力降低，應及時清洗。
(1) If the fuel injector tail pipe is blocked, it shall be cleaned in time. (2) If the regeneration pump and pipeline are blocked and the injection pressure is reduced, it shall be cleaned in time.
