摘要: 利用自行设计的消化反应器对餐厨垃圾和剩余污泥开展高温微氧消化试验，按批式运行方式考察了曝气强度、消化温度、pH值对餐厨垃圾和污泥消化释放碳源过程的影响，以消化体系SCOD和SCFAs最大化为主要指标确定了适宜的消化工艺参数。试验最佳工艺条件为：曝气强度为每升混合物料曝气0.8 L/h，消化温度50℃，pH值9.0。研究表明，适当降低曝气强度和升高温度都有利于餐厨垃圾和污泥的微氧消化效果，有利于碳源的累积。
Abstract: Experiment of high temperature anaerobic digestion on food waste and sewage sludge was carried out by use of designed reactor. Effect of digestive on aeration intensity, digestion temperature and pH value were investigated by batch type of operation mode. SCOD and SCFAs of digestion system were the most important indicator. The optimum technological conditions for research were aer-ation intensity of 0.8 L/(h•Lsludge), digestion temperature of 50˚C and pH of 9.0. Research shows that the property of microaerobic digestion system can be improved by reduced aeration intensity and raise the temperature.
