Abstract

Abstract: The aim was to explore the purification effect of solid waste biochar on intensive piggery wastewater. Four kinds of common biomass feedstock which were corn stovers (CS), pine cones (PC), pistachios shells (PS), palm residues (PR) from agriculture and forestry ecosystem were used to make biochars. Five treatments were named as CS500, PC500, PS500, PR500, PR700, respectively. Physicochemical properties of these solid waste biochars and their purification effects on piggery wastewater were studied. The results showed that component contents of biochars from different feedstocks were different, and could also be affected by pyrolysis temperature. Contents of C, K, Cu, Zn in CS500 and N, P, Fe in PR500 were the highest, and contents of Ca, Mg as well as the pH value in PR700 were the highest. Five kinds of biochars were used to remove COD, NH3- N, TN, TP from piggery wastewater, and their performances were compared. The maximum absorption capacity on COD, NH3-N, TN was 81.62, 43.67 and 10.46 mg/g, respectively, but the biochar had no significant effect on TP. In conclusion, the absorption effect of CS500 was optimal with the absorption capacity of COD, NH3-N, TN, TP being 81.62, 20.75, 10.46, 1.19 mg/g, respectively. The study could provide some scientific information for the further development and utilization of biochar materials in wastewater treatment.
