In recent years, with the continuous shortage of global resource storage and the increasing pressure of environmental governance, more and more biogas purification projects have been constructed. The development and utilization of new resources in line with the current situation is the inevitable direction of energy development in the future. Why is that?

　　1. 根据全球环境和可持续发展政策，有必要发展可再生能源，改善能源结构。

　　1. According to the global environment and sustainable development policies, it is necessary to develop renewable energy and improve the energy structure.

　　目前，中国已成为世界第二大能源消费国，化石燃料的消耗和使用造成了严重的温室效应、酸雨、臭氧层破坏等环境问题。沼气净化促进了能源消费结构和应用模式的创新，促进了多元化、清洁能源的发展。生物天然气作为一种清洁的天然气能源，具有环保循环利用、“废物”为“财富”、副产品应用、技术成熟等特点，在新能源利用方面具有巨大的潜力。

　　At present, China has become the second largest energy consumer in the world. The consumption and use of fossil fuels have caused serious environmental problems such as greenhouse effect, acid rain, ozone layer damage, etc. Biogas purification promotes the innovation of energy consumption structure and application mode, and promotes the development of diversified and clean energy. As a kind of clean natural gas energy, biological natural gas has the characteristics of environmental protection and recycling, "waste" as "wealth", by-product application, mature technology and so on. It has great potential in the utilization of new energy.

　　2. 延伸产业链，提升企业附加值，提升企业竞争力。

　　2. extend the industrial chain, enhance the added value of enterprises and enhance the competitiveness of enterprises.

　　能源企业面临激烈的竞争。生物天然气净化可以延伸企业的产品链条，增加产品附加值，是企业提高竞争力的有效手段之一。

　　Energy companies face fierce competition. Biological natural gas purification can extend the company's product chain and increase the added value of products, which is one of the effective means to improve the competitiveness of enterprises.

　　3.减少温室气体排放的必要性。

　　3. The need to reduce greenhouse gas emissions.

　　由于全球变暖趋势日益严重受到全世界的关注，温室气体减排越来越紧迫。发展可再生能源已成为一项紧迫的任务。通过沼气净化来达到我国节能减排的目的具有重要的意义。

　　As the global warming trend is increasingly concerned by the world, greenhouse gas emission reduction is becoming more and more urgent. The development of renewable energy has become an urgent task. It is of great significance to achieve the goal of energy conservation and emission reduction through biogas purification.
