Pharmaceutical sludge is considered as a hazardous substance with high treatment and disposal fees. Anaerobic digestion could not only transform the hazardous substance into activated sludge, but also generate valuable biogas. This research had two objectives. First: studying the feasibility of anaerobic digestion and determining the biochemical methane potential (BMP) of pharmaceutical sludge under different Inoculum to substrate TS ratios (ISRs) of 0, 0.65, 2.58 and 10.32 in mesophilic condition of 37±1°C. Secondly, investigating the removal efficiency of colistin sulphate during anaerobic digestion. The results showed that the use of anaerobic digestion to treat the pharmaceutical sludge is feasible and that it can completely eliminate the colistin sulphate. The highest biogas production from pharmaceutical sludge is 499.46 mL/g TS at an ISR of 10.32.
制药污泥被认为是一种具有高处理和处置费用的危险物质。厌氧消化不仅可以将危险物质转化为活性污泥，还可以产生有价值的沼气。本研究有两个目的。首先：研究厌氧消化的可行性，并确定在 37±1°C 的中温条件下，接种物与底物总固体（TS）的比例（ISR）分别为 0、0.65、2.58 和 10.32 时，制药污泥的生化甲烷潜力（BMP）。其次，研究在厌氧消化过程中硫酸粘菌素的去除效率。结果表明，利用厌氧消化处理制药污泥是可行的，并且可以完全消除硫酸粘菌素。在 ISR 为 10.32 时，制药污泥的最大沼气产量为 499.46 mL/g TS。
