Abstract

Four batches of potato-processing wastewater were collected every two weeks. After sedimentation for 1 h and subsequent decanting, the supernatant had a 5-day biochemical oxygen demand (BOD) ranging from 620 to 1743 mg/l and total suspended solids ranging from 0.31 to 0.49 mg/ml. Thermophilic aerobic digestion (55°C, 0.6l air/min) decreased the BOD and total suspended solids of the supernatant by 98% and 75%, respectively, in 96 h.

摘要

四个批次的马铃薯加工废水每两周收集一次。经过 1 小时沉淀和后续倾析，上清液的五日生化需氧量（BOD）范围为 620 至 1743mg/L，总悬浮固体（TSS）范围为 0.31 至 0.49mg/ml。在 96 小时内，高温好氧消化（55°C，0.6l/min 空气）使上清液的 BOD 和总悬浮固体分别降低了 98%和 75%。
