Biogas generator units are now widely used, especially in industries such as animal husbandry and food wastewater treatment. As we all know, biogas generators have the characteristics of creating efficiency, energy conservation, safety, and environmental protection, which is also one of the reasons why they are popular. However, when using biogas generator units and biogas digesters, safety should be paid attention to:

我们要注意的是，沼气发电机组新池排放废气期间，禁在导气管口试火，以免发生回火，引起池体爆炸。

We should note that during the discharge of waste gas from the new pool of the biogas generator unit, it is prohibited to conduct a fire test at the outlet of the gas conduit to avoid flashback and explosion of the pool.

清池检修时，须在沼气技术员的指导下进行，禁单独操作。需要特别注意的是，在清空池体后立即通风1—2天，方可入池。入池前须进行动物试验，待池内氧气充足后再下池操作，以防因氧气不足而窒息。 同时，池内严禁点火吸烟。

During the cleaning and maintenance of the pool, it must be carried out under the guidance of the biogas technician, and individual operations are prohibited. Special attention should be paid to immediately ventilate the pool for 1-2 days after emptying it before entering the pool. Animal testing must be conducted before entering the pool, and the operation can only be carried out when there is sufficient oxygen in the pool to prevent suffocation due to insufficient oxygen. Meanwhile, ignition and smoking are strictly prohibited in the pool.

不允许各种农药及有害杂物入池，以免杀死沼气微生物，影响产气。

Various pesticides and harmful substances are not allowed to enter the pool to avoid killing biogas microorganisms and affecting gas production.

室外管路应采取防晒保护措施，延长使用寿命，以免管路风化，引起漏气。

Outdoor pipelines should take sun protection measures to extend their service life and prevent weathering, which may cause air leakage.

灯灶具要远离易燃物品，以免引起火灾。

Lights and stoves should be kept away from flammable materials to prevent fires.

当发现漏气时，及时关闭气源，打开门窗，禁生火吸烟开关电器，以免发生火灾。

When air leakage is found, turn off the air source in a timely manner, open doors and windows, and prohibit starting fires or smoking. Switch on electrical appliances to avoid a fire.

严禁在沼气发电机组沼气池5m范围内生火，以免发生不安全事故。

It is strictly prohibited to start a fire within a 5m range of the biogas digester of the biogas generator set to avoid unsafe accidents.

日常出料时，禁吸烟点火。

Smoking and ignition are prohibited during daily discharge.

燃烧过废弃的纱罩含有毒物质，应深埋处理，严禁手摸误食。

Burnt and discarded gauze covers contain toxic substances and should be buried deep for disposal. It is strictly prohibited to touch or ingest them by hand.

建池及进出料时，应特别注意安全，并及时进行保护措施，以防人畜掉入池中。

Special attention should be paid to safety during the construction of the pool and the inflow and outflow of materials, and protective measures should be taken in a timely manner to prevent humans and animals from falling into the pool.
