之前由于垃圾處理主要以衛(wèi)生填埋的方式來(lái)處理。用這種方式處理的垃圾填埋場(chǎng)會(huì)產(chǎn)生大量的垃圾填埋氣，如果不加以處理或者利用，將對(duì)周邊環(huán)境造成很大的空氣污染，嚴(yán)重影響附近居民的生活品質(zhì)。其中垃圾填埋氣發(fā)電目前是一種主要利用方式。那垃圾填埋場(chǎng)沼氣發(fā)電需要哪些外部條件呢？

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：垃圾填埋場(chǎng)必須是衛(wèi)生填埋的，也就是說(shuō)垃圾填埋場(chǎng)填埋過(guò)程中用到了防滲膜

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

2：垃圾填埋場(chǎng)的垃圾必須是生天然氣發(fā)電機(jī)組活垃圾，建筑垃圾當(dāng)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噸以上，這樣的量才有大量的垃圾填埋氣產(chǎn)生，不然氣量小影響發(fā)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: 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：填埋時(shí)間最少在三年以上，垃圾填埋場(chǎng)設(shè)計(jì)在10年以上填埋時(shí)間。

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：如果要垃圾填埋氣發(fā)電上網(wǎng)的話(huà)還要考慮最近的上網(wǎng)地點(diǎn)離垃圾填埋場(chǎng)的距離是否太遠(yuǎn)，太遠(yuǎn)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. If it is too far, the investment is very high.
