沼氣發(fā)酵微生物是人工生產(chǎn)沼氣的重要因素。沼氣微生物數(shù)量眾多，可以獲得各種微生物的基本生長條件，因此沼氣發(fā)酵原料可以在微生物的作用下轉(zhuǎn)化為沼氣。大型沼氣工程的啟動(dòng)和調(diào)試是指沼氣池中厭氧活性污泥的過程從接種物和原料開始，經(jīng)過馴化和培養(yǎng)，逐漸增加沼氣池中厭氧活性污泥的數(shù)量和活性，直至沼氣池運(yùn)行達(dá)到要求的過程。
Biogas fermentation microorganism is an important factor in the artificial production of biogas. There are a large number of biogas microorganisms, which can obtain the basic growth conditions of various microorganisms. Therefore, biogas fermentation raw materials can be transformed into biogas under the action of microorganisms. The start-up and commissioning of large-scale biogas project refers to the process of anaerobic activated sludge in biogas digester, starting from inoculum and raw materials, through domestication and cultivation, gradually increasing the amount and activity of anaerobic activated sludge in biogas digester until the operation of biogas digester meets the requirements.
關(guān)于大型沼氣工程的啟動(dòng)調(diào)試應(yīng)在工程竣工驗(yàn)收合格后進(jìn)行，同時(shí)還應(yīng)做好下列的運(yùn)行管理的基本要求：
The start-up and commissioning of large-scale biogas project shall be carried out after the project is completed and accepted. Meanwhile, the following basic requirements for operation and management shall be well done:
1、運(yùn)行管理人員要熟悉大型沼氣工程工藝、設(shè)施設(shè)備的運(yùn)行要求和技術(shù)指標(biāo)；
1. The operation and management personnel must be familiar with the operation requirements and technical indicators of large-scale biogas engineering process, facilities and equipment;
2、操作人員要熟悉該位置設(shè)施設(shè)備的操作要求和技術(shù)指標(biāo)，并了解沼氣工程工藝流程；
2. Operators must be familiar with the operation requirements and technical indicators of the facilities and equipment at the location, and understand the process flow of biogas engineering;
3、操作人員應(yīng)準(zhǔn)時(shí)準(zhǔn)確填寫操作記錄，運(yùn)營管理人員應(yīng)定期檢查原始記錄；
3. The operators should fill in the operation records timely and accurately, and the operation management personnel should regularly check the original records;
4、運(yùn)行管理人員和操作人員應(yīng)按照工藝和管理規(guī)定檢查結(jié)構(gòu)、設(shè)備、電器和儀表的操作。
4. Operation management personnel and operators shall check the operation of structure, equipment, electrical appliances and instruments according to process and management regulations.
大型沼氣工程管理要點(diǎn)：
Management points of large-scale biogas project:
1、投料量和周期應(yīng)按工藝設(shè)計(jì)參數(shù)進(jìn)行，并在實(shí)踐中摸索出參數(shù)；
1. The feeding quantity and cycle should be carried out according to the process design parameters, and the excellent parameters can be found out in practice;
2、維持相對(duì)穩(wěn)定的厭氧消化溫度；
2. Maintain relatively stable anaerobic digestion temperature;
3、厭氧消化器的攪拌根據(jù)工藝要求進(jìn)行。采用沼氣攪拌的，在啟動(dòng)期間或產(chǎn)氣量不足時(shí)，應(yīng)輔以機(jī)械或泵等其它方式攪拌；
3. The mixing of anaerobic digester is carried out according to the process requirements. If biogas is used for mixing, machinery or pump should be supplemented during start-up or when gas production is insufficient;
4、厭氧消化器的攪拌不得與排泥同時(shí)進(jìn)行；
4. The mixing of anaerobic digester should not be carried out simultaneously with sludge discharge;
5、宜每日監(jiān)測：pH值、揮發(fā)酸、總堿度、溫度、氣壓、產(chǎn)氣量和沼氣成分等指標(biāo)，掌握厭氧消化池運(yùn)行工況，并根據(jù)監(jiān)測數(shù)據(jù)及時(shí)調(diào)整大型沼氣工程運(yùn)行方案或采取相應(yīng)措施。
5. Daily monitoring: pH value, volatile acid, total alkalinity, temperature, air pressure, biogas composition and other indicators should be monitored daily to master the operation conditions of anaerobic digestion tank, and timely adjust the operation scheme of large-scale biogas project or take corresponding measures according to the monitoring data.
The above is about how to carry out the operation and management of large-scale biogas project. I hope it will help you. If you want to know more, please consult the biological desulfurization http://www.fengkecheng.cn Official website.
