之前由于垃圾处理主要以卫生填埋的方式来处理。用这种方式处理的垃圾填埋场会产生大量的垃圾填埋气，如果不加以处理或者利用，将对周边环境造成很大的空气污染，严重影响附近居民的生活品质。其中垃圾填埋气发电目前是一种主要利用方式。那垃圾填埋场沼气发电需要哪些外部条件呢？

Previously, 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 biogas power generation in landfills?

1：垃圾填埋场必须是卫生填埋的，也就是说垃圾填埋场填埋过程中用到了防渗膜

1: The landfill must be sanitary, which means that anti-seepage membranes are used during the landfill process

2：垃圾填埋场的垃圾必须是生天然气发电机组活垃圾，建筑垃圾当然不行

2: The garbage from landfills must be live waste from natural gas generators, and construction waste is not allowed

3：日填生活垃圾在500吨以上，这样的量才有大量的垃圾填埋气产生，不然气量小影响发电量，以及投资收益率，如果气量小可以考虑用沼气焚烧火炬把这些气体焚烧掉。

3: A daily amount of household waste exceeding 500 tons is necessary to generate a large amount of landfill gas. Otherwise, a small amount of gas will affect power generation and investment returns. If the amount of gas is small, it can be considered to use a biogas torch to incinerate these gases.

4：填埋时间最少在三年以上，垃圾填埋场设计在10年以上填埋时间。

4: The landfill time should be at least three years, and the design of the landfill site should have a landfill time of at least 10 years.

5：如果要垃圾填埋气发电上网的话还要考虑最近的上网地点离垃圾填埋场的距离是否太远，太远投资非常大。

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. If it is too far, the investment is very high.
