1.西北地区“四位一体”温室生态模式所谓“四位一体”是在太阳能温室的一端建地下沼气池,池上建猪舍、厕所,有的还在温室的一端建地下热交换系统。在这一系统中,人畜粪便进入沼气池,经过厌氧发酵变成高效的有机肥料。沼渣作底肥,沼液可以直接浇菜,沼气除炊用外,还可以在温室内点灯,既增加棚内温度和光照时间,又增加了棚内二氧化碳的浓度。大棚温室的适宜温度还为猪、禽的冬季育肥生长提供了良好的条件,同时也保证了沼气池冬季能正常运行产气。“四位一体”以太阳能为动力,以土地为基础,实现种植、养殖与沼气并举的一个较为完整的能源生态经济体系。
1. Northwest Territories “Four in One ” Greenhouse Ecological Model The so-called “Four in One ” is built at the end of the solar greenhouse greenhouse underground digesters, ponds built pig homes, toilets, and some still in the greenhouse built underground heat Exchange system. In this system, man and manure enter the digester and become an efficient organic fertilizer after anaerobic fermentation. Biogas residue at the end of fertilizer, biogas slurry can be directly poured vegetables, biogas in addition to cooking, but also in the greenhouse lighting, both to increase the greenhouse temperature and light time, but also increased the shed concentration of carbon dioxide. Greenhouse greenhouse temperature is suitable for pigs, poultry winter fattening growth provides a good condition, but also to ensure that the biogas digester in winter can be normal gas production. “Four in One ” A solar energy-powered, land-based, to achieve planting, breeding and biogas simultaneously a more complete energy eco-economic system.
