我市自1997年开展“四位一体”(厕所、畜棚、沼气池、日光温室)能源生态农业模式生产以来,取得了一定的经济效益和生态效益。但由于此模式是新生事物,技术指导一旦滞后,就会因管理不善,使用不当而产生副作用。因此,必须用科学的态度对待这一新生事物,充分认识其内在规律,才能保证最大的收益,达到预期的目的。现将其冬春季管理要点摘录如下,以供各“四位一体”用户参考。1 合理使用沼气 在“四位一体”模式中,要求使用沼气的工作间和猪舍应在棚的同一侧,在沼气炉与作物之间,以猪舍作为缓冲间,防止当脱硫效果不良时,沼气燃烧后产
Since 1997, the city has achieved certain economic and ecological benefits since it started the production of the energy-based ecological agriculture model of “four in one” (toilets, barns, digesters and solar greenhouse). However, since this model is newborn, once the technical guidance lags behind, it will cause side effects due to poor management and improper use. Therefore, we must treat this new thing with a scientific attitude and fully understand its inherent laws so as to ensure the maximum benefits and achieve the desired goals. Now winter and spring management points are summarized below, for the “four in one” user reference. 1 Reasonable use of biogas In the “four in one” mode, workplaces and pighouses requiring biogas should be on the same side of the shed, between the biogas furnace and the crops, with pig houses as buffers to prevent the desulfurization effect from being poor Biogas combustion after production
