之前由于垃圾處理主要以衛生填埋的方式來處理。用這種方式處理的垃圾填埋場會產生大量的垃圾填埋氣，如果不加以處理或者利用，將對周邊環境造成很大的空氣污染，嚴重影響附近居民的生活品質。其中垃圾填埋氣發電目前是一種主要利用方式。那垃圾填埋場沼氣發電需要哪些外部條件呢？
Previously, due to the fact that garbage disposal was mainly carried out through sanitary landfilling. The landfill site treated in this way will generate a large amount of landfill gas. If not treated or utilized, it will cause significant air pollution to the surrounding environment and seriously affect the quality of life of nearby residents. Among them, landfill gas power generation is currently the main utilization method. What external conditions are required for landfill biogas power generation?
1：垃圾填埋場必須是衛生填埋的，也就是說垃圾填埋場填埋過程中用到了防滲膜
1: The landfill site must be sanitary, which means that anti-seepage membranes are used during the landfill process
2：垃圾填埋場的垃圾必須是生天然氣發電機組活垃圾，建筑垃圾當然不行
2: The garbage in the landfill must be the live garbage of the raw natural gas generator set, of course not Construction waste
3：日填生活垃圾在500噸以上，這樣的量才有大量的垃圾填埋氣產生，不然氣量小影響發電量，以及投資收益率，如果氣量小可以考慮用沼氣焚燒火炬把這些氣體焚燒掉。

3: Daily filling of household waste is above 500 tons, which is the amount that generates a large amount of landfill gas. Otherwise, a small amount of gas will affect power generation and investment returns. If the gas volume is small, it can be considered to use a biogas incineration torch to burn these gases.
4：填埋時間少在三年以上，垃圾填埋場設計在10年以上填埋時間。
4: The landfill time should be at least three years, and the design of the landfill site should be at least 10 years.
5：如果要垃圾填埋氣發電上網的話還要考慮近的上網地點離垃圾填埋場的距離是否太遠，太遠投資非常大。
5: If you want landfill gas power generation to be connected to the grid, you also need to consider whether the nearest connection point is too far from the landfill site, as it would be very expensive.
只有滿足以上幾點的基本條件，對于是否投資垃圾填埋場有意義的考量。當然還有其他的因素也會影響到垃圾填埋氣發電。
Only meeting the basic conditions mentioned above is a meaningful consideration for whether to invest in a landfill. Of course, there are other factors that can also affect landfill gas power generation.
