The influence of tetracycline (TC) antibiotics on phosphine (PH) production in the anaerobic wastewater treatment was studied. A lab-scale anaerobic baffled reactor with three compartments was employed to simulate this process. The reactor was operated in a TC-absence wastewater and 250μg/L TC-presence wastewater for three months after a start-up period, respectively. The responses of pH, oxidation-reduction potential (ORP), chemical oxygen demand (COD), total phosphorus (TP), enzymes activity (dehydrogenase and acid phosphatase), and microbial community were investigated to reveal the effect of TC on PH production. Results suggested that the dehydrogenase (DH) activity, acid phosphatase (ACP) activity and COD have positive relationship with PH production, while pH, ORP level and the TP in liquid phase have negative relationship with PH production. With prolonged TC exposure, decrease in pH and increase in DH activity are beneficial to PH production, while decrease in COD and ACP activity are not the limiting factors for PH production.
研究了四环素（TC）抗生素对厌氧废水处理中磷化氢（PH）生成的影响。采用三室厌氧折流反应器模拟这一过程。在启动阶段后，分别在无 TC 废水和 250μg/L TC 存在的废水中运行三个月。研究了 pH、氧化还原电位（ORP）、化学需氧量（COD）、总磷（TP）、酶活性（脱氢酶和酸性磷酸酶）和微生物群落的响应，以揭示 TC 对 PH 生成的影响。结果表明，脱氢酶（DH）活性、酸性磷酸酶（ACP）活性和 COD 与 PH 生成呈正相关，而 pH、ORP 水平和液相中的 TP 与 PH 生成呈负相关。随着 TC 暴露时间的延长，pH 值降低和 DH 活性增加有利于 PH 生成，而 COD 和 ACP 活性降低不是 PH 生成的限制因素。
