摘要: Aquaculture produces numerous by-products like aquatic plants, algae, and nutrient-enriched sediment annually, which are often discarded as waste, are not environmentally friendly, and are harmful to the environment. In this study, aquaculture by-products were utilized to prepare moss biochar at 500, 700, and 800 C-degrees (BC500, BC700, and BC800, respectively); Elodea biochar (WBC800) at 800(degrees)C; and sediment biochar (SBC800) at 800 C-degrees. Characterization and experimental results showed that BC800 had the best adsorption effect on geosmin (GSM) under the same conditions; when using BC800 to treat GSM solution with a pH of 7, the adsorption efficiency of GSM was high (97.08%) under the conditions of dosage of 1.0 g, temperature of 25 C-degrees, and adsorption time of 2 min. Adsorption is a multimolecular layer process that involves both physical aspects of porous adsorption and connections between chemical bonds. Biochar, derived from aquaculture by-products, is utilized to eliminate odorous substances in aquaculture environments, thereby promoting resource recycling.
