Complementary characterization of waste activated sludge during sustainable low-temperature pretreatment for enhanced biogas production

Low-temperature pretreatment process to waste activated sludge was used to improve biogas production during the anaerobic digestion process.针对剩余活性污泥（waste activated sludge）的低温预处理工艺，可提升厌氧消化（anaerobic digestion）过程中的沼气产量。
