Antibiotic residues are difficult to be treated or utilized because of their high water content and residual antibiotics. This article is devoted to investigating the possibility of biogas production from cephalosporin C residue (CPCAR), one typical type of antibiotic residues, via anaerobic digestion in combination with hydrothermal pretreatment (HTPT). The results from the bench-scale experiments showed that the combination of HTPT and anaerobic digestion can provide a viable way to convert CPCAR into biogas, and the biogas and methane yields reached 290 and 200 ml(g TS)(-1), respectively. This article further evaluated the proposed technology in terms of energy balance and technical feasibility based on theoretical calculation using the data from a pilot HTPT test. It was shown that the process is totally self-sufficient in energy and its main challenging problem of ammonia inhibition can be solved via ammonia stripping.
由于其含水量高和残留抗生素，抗生素残留难以处理或利用。本文致力于研究通过厌氧消化结合水热预处理（HTPT）从头孢菌素 C 残留（CPCAR）一种典型的抗生素残留中生产沼气的可能性。中试规模实验结果表明，HTPT 和厌氧消化的组合为将 CPCAR 转化为沼气提供了一种可行的方法，沼气和甲烷产率分别达到 290 和 200ml（gTS）（-1）。本文还进一步根据中试 HTPT 试验的数据通过理论计算从能量平衡和技术可行性方面评估了该技术。结果表明，该工艺在能量上完全自给自足，其主要的氨抑制问题可以通过氨汽提来解决。
