摘要:
厌氧发酵是餐厨垃圾无害化和资源化处理的重要技术手段，而温度是影响厌氧发酵的重要参数。西安市餐厨垃圾资源化利用和无害化处理项目（一期）的厌氧工段采用优化发酵条件，着重介绍了中温和高温过渡区发酵温度为43~45 ℃时的餐厨垃圾厌氧发酵技术，并对项目稳定运行期的生产数据进行分析总结。结果表明，采用中温和高温过渡区厌氧发酵技术，有机负荷率高，垃圾挥发性固体（VS）产气率达到1 170 m3/tVS，全混发酵CSTR发酵装置容积产气率达3.0 m3/(m3·d) 以上，取得了良好运行效果。
Abstract:
Anaerobic digestion is an important technology for harmless and resource treatment of food waste, and temperature is an important affecting parameter. The fermentation technology at mesophilic and thermophilic temperature (43-45 ℃) adopted in the anaerobic section of Xi’an food waste biogas project (phase Ⅰ) is introduced, and the stable operation data of the project are analyzed and summarized. The results show that by using the anaerobic digestion technology at mesophilic and thermophilic temperature, the organic load rate is high, the gas production rate of volatile solid (VS) of waste is 1 170 m3/tVS, and the volume gas production rate of full mixed CSTR fermentation unit is more than 3.0 m3/(m3·d), so that good operation results are achieved.
