Treatment of Separated Pig Manure Digestate Using Woodchip Biofilters

摘要：

　　Three pilot-scale biofilters consisting of 1m aerobic woodehip layers and 0.5 m submerged woodehip layers were constructed to treat the separated pig manure anaerobic digestate (SAD).Reductions of 54% dry matter, 80% of chemical oxygen demand (COD), 93% of 5-day biochemical oxygen demand (BOD5), 86% of total nitrogen (TN) and 79% of total phosphorus (TP) were achieved.The study results confirm the occurrence of nitrification in the aerobic woodchip layers and denitrifieation in the submerged layers.The woodchip biofilters can be used for large-scale SAD treatment before landspreading so as to meet the stringent Nitrates directive.
