厌氧消化处理餐饮有机垃圾初探

The Laboratory Experiment on Anaerobic Digestion of Municipal Dietetic Organic Wastes

采用厌氧消化工艺处理餐饮有机垃圾 ,实验获得较高的COD去除率和TS去除率 ,厌氧消化液和消化固体可以作肥料来使用 ,结果表明厌氧消化处理方法可行。同时工艺参数建议水力停留时间以 2 0d为宜 ,容积负荷应小于 3.5gCOD/(L·d)。

The authers the municipal dietetic organic wastes with anaerobic digestion in lab and obtained the removal rates of COD and TS. The digested solid and out flow can be used as fertilizer. The results show anaerobic digestion is an accessible way to treat the municipal dietetic organic wastes. The appropriate HRT should be 20 days. The VLR may be less than 0.65 gCOD/ (L·d).
