Abstract |
To evaluate the effects of aeration on co-digestates, we investigated the chemical contents of aerobic liquefying processes. The six co-digestates were continuously aerated with 0.1 m3air/m3¡¤min for 54 days. The three measured chemical contents (T-N, BOD5,and CODMn)were all decreased after aeration. Meanwhile, NO3-N, DO, and ORP were all increased after aeration. A standard procedure for fertilizers in anaerobic solutions has not yet been set in agriculture. The livestock liquid manure should have a proportion of 0.3% for T-N, T-P, and T-K. In this study, the aerobic liquid fertilizer was above the standard level(0.3%), suggesting the utilization of co-digestates.
