1、 Feeding stage

1、通过管道运输或人工将猪粪等发酵原料经进料斗过格栅入进料池。

1. Pig manure and other fermentation raw materials are transported by pipeline or manually into the feed tank through the feed hopper through the grid.

2、发酵原料需加水、沼液调配浓度。

2. The raw materials for fermentation need to be mixed with water and biogas slurry.

3、启动进料搅拌器，搅拌3-5min后停止搅拌，打开进料管上的进料阀门，启动进料切割泵。

3. Start the feed agitator, stop mixing after 3-5min, open the feed valve on the feed pipe, and start the feed cutting pump.

4、待进料池物料降至进料界面以下时，即关闭进料切割泵，再关闭进料阀门。

4. When the material in the feed pool falls below the feed interface, close the feed cutting pump, and then close the feed valve.

5、物料进入厌氧发酵进行厌氧处理后，每隔24小时通过取样管进行取样分析检测，实时监控发酵状态。

5. After the material enters anaerobic fermentation for anaerobic treatment, the sampling pipe is used for sampling analysis and detection every 24 hours to monitor the fermentation state in real time.

6、沼气发电机组厂家表示启动运转正常后，可陆续向罐内进料，每日进料约9～15立方，待进料量达到容积的85%～90%时，进料停止后，启动循环泵3-5min后停止。

6. The biogas generator manufacturer said that after the start-up and operation are normal, it can feed into the tank one after another. The daily feed is about 9-15 cubic meters. When the feed volume reaches 85% - 90% of the volume, the feed is stopped, and the circulating pump is started for 3-5 minutes.

二、出料阶段

2、 Discharge stage

1、出料时，缓慢打开溢流管上的出料阀门，打开至1／3～1／2左右，以免出料过快产生负压。待无沼液排出后，关闭阀门。

1. When discharging, slowly open the discharge valve on the overflow pipe to about 1 / 3 ~ 1 / 2, so as to avoid negative pressure caused by too fast discharging. After no biogas slurry is discharged, close the valve.

2、排泥时，先打开溢流管阀门，后缓慢打开排泥管上的出料阀门，打开至1／3～1／2左右以免出料过快产生负压。待无大量污泥排出后，关闭排泥管阀门，再关闭溢流管阀门。

2. When discharging sludge, first open the overflow pipe valve, and then slowly open the discharge valve on the sludge discharge pipe to about 1 / 3 ~ 1 / 2, so as to avoid negative pressure caused by too fast discharging. After no large amount of sludge is discharged, close the valve of sludge discharge pipe and then close the valve of overflow pipe.

三、使用阶段

3、 Use stage

1、沼气火炬具备自动点火功能，当气柜内沼气过多，自动进入沼气火炬内。

1. The biogas torch has the function of automatic ignition. When there is too much biogas in the gas holder, it will automatically enter into the biogas torch.

2、使用发电机时，打开发电机进气阀门，按照沼气发电机组操作规程操作。

2. When using the generator, open the air inlet valve of the generator and operate according to the operating procedures of biogas generator set.

3、使用锅炉时，打开锅炉进气阀门，按照沼气锅炉使用说明操作。

3. When using the boiler, open the air inlet valve of the boiler and operate according to the operating instructions of the biogas boiler.

4、正常使用时脱水脱硫阀门正常打开，需要维修时由工程技术人员关闭阀门进行维修，脱水脱硫罐每隔3-7天打开排水阀门进行排水。

4. In normal use, the dehydration and desulfurization valve is normally opened. When maintenance is needed, the engineering and technical personnel shall close the valve for maintenance. The dehydration and desulfurization tank shall open the drainage valve every 3-7 days for drainage.
