摘　　要：我国餐厨垃圾具有产量大、难以收集处理的特点,易导致环境污染。本文研究了不同温度、铁源的三价铁-生物炭复合材料对餐厨废弃物厌氧发酵产氢的影响。结果表明,与空白实验组相比,煅烧温度为600℃,以硫酸铁为铁源制备的铁基生物炭可提高微生物酶的活性,同时使更多的微生物附着,对餐厨垃圾厌氧发酵产氢的促进作用最佳,产氢量提高约15.47%。Food waste in China has the characteristics of large output and difficult to collect and treat,which is easy to cause environmental pollution.The effect of ferric iron biochar composites with different temperature and iron source on hydrogen production from kitchen waste by anaerobic fermentation was studied.The results showed that,compared with the blank experimental group,the iron-based biochar prepared with ferric sulfate as iron source at the calcination temperature of 600℃could improve the activity of microbial enzymes and attach more microorganisms.It had the best promoting effect on the anaerobic fermentation of food waste,and the hydrogen production was increased by about 15.47%.
