Abstract

A 50-day anaerobic digestion test is conducted by mixing raw pig manure with maize straw at dry matter mass ratios of 1:1 and 2:1 at the temperature of (35±1) ℃. The fractions of Cu and Zn of the co-digestion fermentation materials and the biogas residues are measured by modified BCR extraction and 0.01 mol·L-1 CaCl2 extraction processes, respectively. The results showed that the concentrations of leachable fraction and the percentages of bioavailability (sum percentages of exchangeable and reducible fractions) of Cu and Zn all decreased in biogas residues, and the stability (sum percentages of oxidizable and residual fractions) of Cu and Zn all increased in biogas residues during anaerobic co-digestion.
