Pre operation inspection of biological desulfurization system I
检查沼气流经系统的各阀门控制情况，开和关要到位。
Check the control status of each valve in the biogas flow system, and ensure that the opening and closing are in place.
检查循环水管路上的阀门正确使用情况。
Check the correct use of valves on the circulating water pipe.
检查各仪表，仪器是否完好，有无漏气、漏水存在，能否正常运行。
Check whether all instruments are in good condition, whether there are any air or water leaks, and whether they can operate normally.
检查每个用水点水位，系统严禁缺水运行。
Check the water level of each water point, and the system is strictly prohibited from running short of water.
二运行中注意事项
II. Precautions during operation
设备启动前在控制柜触屏上要确定与之相对应的设备按键。
Before starting the device, it is necessary to determine the corresponding device button on the touch screen of the control cabinet.
循环水泵开启后，应观察水泵是否上水，压力表正常稳定。
After the circulating water pump is started, it should be observed whether the water pump is filled with water and whether the pressure gauge is normal and stable.
各设备启动后，注意机器声音、电流、振动情况、温度、螺丝是否松动。
After starting each device, pay attention to the machine's sound, current, vibration, temperature, and whether screws are loose.
每天按时用手持式检测仪测生物脱硫后H2S三--四次。
Use a handheld detector to measure H2S after biological desulfurization three to four times a day on time.
营养盐计量泵，氢氧化钠潜污泵24小时应有正常工作水位，两桶加水时不要让液体溢出桶外。
The nutrient metering pump and sodium hydroxide submersible sewage pump should have a normal working water level within 24 hours, and do not allow the liquid to overflow when adding water to two buckets.
The water temperature of the aeration tank is controlled at 32 ℃ - 35 ℃, the PH value of alkali desulfurization is controlled at 8-8.5, and the oxidation reduction potential is between - 320 and 260mv.
三维护保养
3D Care
每天将系统内冷凝水排水阀放空。
Empty the condensate drain valve in the system every day.
严格执行交接班制度，并做好设备运行记录、各项指标参数记录。
Strictly implement the handover system and keep records of equipment safety operation and various indicator parameters.
定期对设备除尘，润滑，防锈（一个月一次），保持环境干洁。
Regularly dust, lubricate, and rust the equipment (once a month) to maintain a dry and clean environment.
每天往洗气水箱注水15分钟，达到脏水置换作用，一个月整体换一次水.
Fill the gas washing water tank with water for 15 minutes every day to achieve the effect of replacing dirty water. Change the water as a whole once a month
