Abstract

Antibiotic residues have significantly effects on aerobic composting process. This study was targeted at antibiotic composite pollutants (e.g., sulfanilamides, tetracyclines, and quinolones) and probed into the effects of pollution levels on aerobic composting. With higher initial antibiotic concentrations, the NH4+ –N and NO3− –N concentrations at the end of composting were higher, but TN content decreased, which may be due to the inhibition effects of antibiotics on nitrogen-fixing bacteria and thus were unfavorable for nitrogen accumulation. Antibiotic pollution obviously delayed composting maturity, and the antibiotics at initial concentration above 306.12 mg/kg were significantly toxic to seeds. Analysis of structural changes in dissolved organic matter (DOM) showed the humification after treatments CK and AT100 mainly occurred at the high-temperature stage (day 2–14) and later lower-temperature maturity stage (day 21–36). Humification after treatment AT300 mainly happened at the high-temperature stage (day 2–14), and that in AT600 mainly occurred at the early temperature rise and high-temperature stage (day 2–7). This study comprehensively evaluated the effect of antibiotic composite pollution on the maturity of aerobic compost, and provided a theoretical basis for the treatment of antibiotic composite pollution materials in practical production.

抗生素复合污染下好氧堆肥过程中氮和腐殖质的变化
抗生素残留对好氧堆肥过程有显著影响。本研究针对抗生素复合污染物(如磺胺类、四环素类、喹诺酮类),探讨污染水平对好氧堆肥的影响。初始抗生素浓度越高,堆肥后期NH4+ -N和NO3−-N浓度越高,TN含量越低,这可能是由于抗生素对固氮菌的抑制作用,不利于氮素积累。抗生素污染明显延迟堆肥成熟,初始浓度大于306.12 mg/kg的抗生素对种子的毒性显著。可溶性有机质(DOM)结构变化分析表明,CK和AT100处理腐殖质化主要发生在高温期(2 ~ 14 d)和较晚的低温成熟期(21 ~ 36 d)。处理AT300后腐殖质化主要发生在高温阶段(2 ~ 14 d),处理AT600腐殖质化主要发生在升温前期和高温阶段(2 ~ 7 d)。本研究综合评价了抗生素复合污染对好氧堆肥成熟度的影响,为实际生产中抗生素复合污染材料的处理提供了理论依据。
