| 摘 要： | 以校园餐厨垃圾为原料,分析测定了早餐、午餐和晚餐餐厨垃圾的总固体(TS)、挥发性固体(VS)、碳水化合物、蛋白质、脂肪含量以及无机盐离子浓度,并通过批式厌氧发酵试验对3种餐厨垃圾的厌氧消化性能进行了对比研究。结果表明,早餐餐厨垃圾特性与午餐/晚餐餐厨垃圾差异较大,Na+,Ca2+和Cl-含量高于后两者。餐厨垃圾不同特性对其厌氧消化产气及有机物去除率都有一定影响,早餐、午餐和晚餐餐厨垃圾的累积甲烷产量分别为212.2,331.6和362.4 ml/g,早餐餐厨垃圾产气量比午餐和晚餐餐厨垃圾分别低36%和41.4%,其中Cl-含量高可能是造成其产气量低的主要原因。 |

| Abstract: | The characteristics of wastes from breakfast,lunch and dinner were investigated and de-termined,including total solids(TS),volatile solids(VS),carbohydrate,protein,lipids,and inor-ganic salt concentrations.The digestibility of three kinds of kitchen wastes were tested in batch anaerobic digesters.The results showed that there were large differences between breakfast waste and lunch/dinner wastes,especially,the Na+,Ca2+ and Cl-contents in breakfast waste is higher than the other two.It was found that the cha... |
