Anaerobic treatment of pre-settled cosmetic wastewater in batch and continuous experiments has been investigated. Biodegradability tests showed high COD and solid removal efficiencies (about 70%), being the hydrolysis of solids the limiting step of the process. Continuous treatment was carried out in an upflow anaerobic sludge blanket reactor. High COD and TSS removal efficiencies (up to 95% and 85%, respectively) were achieved over a wide range of organic load rate (from 1.8 to 9.2g TCODL(-1)day(-1)). Methanogenesis inhibition was observed in batch assays, which can be predicted by means of a Haldane-based inhibition model. Both COD and solid removal were modelled by Monod and pseudo-first order models, respectively.
采用批式和连续实验对预沉降化妆品废水进行了厌氧处理研究。生物降解性测试表明 COD 和固体去除效率较高(约 70%),其中固体的水解是该过程的限制步骤。连续处理在升流式厌氧污泥床反应器中进行。在较宽的有机负荷率范围内(从 1.8 到 9.2g TCODL(-1)day(-1)),COD 和 TSS 去除效率较高(分别高达 95%和 85%)。在批式实验中观察到甲烷生成抑制作用,这可以通过基于 Haldane 的抑制模型进行预测。COD 和固体去除分别通过 Monod 模型和准一级模型进行模拟。
