Under the situation of increasing energy shortage and environmental protection requirements, biogas utilization is of practical significance for enriching and improving energy structure, alleviating the imbalance between energy supply and demand, improving the utilization rate of renewable resources, reducing the consumption of non-renewable energy, avoiding environmental pollution caused by waste, reducing the production costs of industry, agriculture and animal husbandry, and raising the utilization value of by-products. Therefore, the development of biogas desulfurization technology needs to pay attention to the following points:
(1)完善可再生能源鼓励政策，针对沼气工程的能量多层次应用和物质循环应用，既产生节能减排的公益性又带来环境效益，政府应加大财政补贴和扶持力度，给予一些优惠政策，鼓舞开展；
(1) To improve the policy of encouraging renewable energy, in view of the multi-level application of energy and material recycling in biogas projects, which not only produces the public benefits of energy conservation and emission reduction, but also brings environmental benefits, the government should increase financial subsidies and support, and give some preferential policies to encourage the development;
(2)增强沼气工程新技术和新设备研发，进步效率，降低工程本钱。特别是合适偏僻地域和孤岛等地综合应用的小型沼气应用技术开发；
(2) Enhance the research and development of new technologies and equipment for biogas engineering, improve efficiency and reduce project cost. Especially suitable for the development of small-scale biogas application technology in remote areas and isolated islands.
(3)对多原料高浓度结合发酵技术研讨，保证产气原料充足，进步安装产气率。沼气工程向集中化、大型化的方向开展，进步工程经济性和能源效率；
(3) Discuss the technology of multi-raw material high concentration combined with fermentation to ensure sufficient raw materials for gas production and improve installation gas production rate. The biogas project should be carried out in the direction of centralization and large-scale, so as to improve the economy and energy efficiency of the project.
(4)沼气发电和用于燃料电池，是有效应用沼气资源的新途径，具有很大的开展潜力；
(4) Biogas power generation and fuel cell are new ways to effectively utilize biogas resources and have great potential for development.
(5)沼气综合应用技术开发，展开沼气提纯技术，可使沼气注入自然气网用做燃料，或替代汽油、柴油用于车辆，完成沼气应用高端化，进步能源效益。
(5) The development of comprehensive application technology of biogas and the development of biogas purification technology can make biogas injected into natural gas network as fuel, or replace gasoline and diesel oil for vehicles to achieve high-end application of biogas and improve energy efficiency.
(6)完善和合理规划养殖与种植产业规划，完成资源综合均衡应用，减少保送本钱，进步效益。
(6) Improve and rationally plan the breeding and planting industry planning, complete the comprehensive and balanced application of resources, reduce the cost of delivery, and improve efficiency.
(7)推行沼气乡村开展，前景非常宽广；
(7) Promoting biogas rural development has broad prospects;
(8)沼气脱硫技术开展相对较成熟，但仍有很多弊端，需进一步完善，防止形成二次污染，完成循环应用。
(8) Biogas desulfurization technology is relatively mature, but there are still many drawbacks, which need to be further improved to prevent secondary pollution and complete the cycle application.
