Anaerobic treatment of wastewater and waste organic solvents originating from the pharmaceutical and chemical industries was tested in a pilot anaerobic membrane bioreactor, which was operated for 580days under different operational conditions. The goal was to test the long-term treatment efficiency and identify inhibitory factors. The highest COD removal of up to 97% was observed when the influent concentration was increased by the addition of methanol (up to 25gL as COD). Varying and generally lower COD removal efficiency (around 78%) was observed when the anaerobic membrane bioreactor was operated with incoming pharmaceutical wastewater as sole carbon source. The addition of waste organic solvents (>2.5gL as COD) to the influent led to low COD removal efficiency or even to the breakdown of anaerobic digestion. Changes in the anaerobic population (e.g., proliferation of the genus Methanosarcina) resulting from the composition of influent were observed.
采用中试规模的厌氧膜生物反应器对来源于制药和化工行业的废水和废有机溶剂进行了厌氧处理试验，该反应器在不同操作条件下运行了 580 天。目的是测试长期处理效率并确定抑制因素。当通过添加甲醇（高达 25gL 作为 COD）来提高进水浓度时，观察到最高 COD 去除率高达 97%。当采用进水的制药废水作为唯一碳源时，观察到变化且通常较低的 COD 去除效率（约 78%）。向进水中添加废有机溶剂（>2.5gL 作为 COD）会导致 COD 去除效率低，甚至导致厌氧消化崩溃。观察到由于进水组成而引起的厌氧种群（例如 Methanosarcina 属的增殖）的变化。
