Inhibition of Sulfate Reduction in Anaerobic Bioreactors

该项目的目标是确定将 抑制硫酸盐还原成硫化氢的生物反应器， 来自废水处理的厌氧消化污泥。 实验将在分批培养中进行，以确定 抑制剂的有效性，抑制剂/拮抗剂的重要性 的作用，及其机制。 缓蚀剂添加方式 将在附着膜蒸煮器中进行研究， 形成生物膜 附片研究，以确定 饲料强度、有机负荷和扩散限制对 规划了硫酸盐还原菌的竞争力。 厌氧反应器广泛应用于有机物的稳定化 在废水处理厂。 这个项目可能会提供 为工程设计人员提供流程改进指南， 减少或消除由氢气生产引起的问题 在此过程中的硫化物的操作。

The objective of this project is to determine conditions that will inhibit sulfate reduction to hydrogen sulfide in bioreactors used to anaerobically digest sludges derived from treatment of wastewater. Experiments will be conducted in batch cultures to determine the effectiveness of inhibitors, the importance of inhibitor/antagonist rations, and their mechanism of action. Modes of inhibitor addition will be studied in attached-film digesters both during start-up and with established biofilms. Attached-film studies to determine the effect of feed strength, organic loading, and diffusion limitation on the competitiveness of the sulfate-reducing bacteria are planned. Anaerobic reactors are widely used for stabilization of organic matter in wastewater treatment plants. this project is likely to provide guidance to engineering designers for process improvement that will reduce or eliminate problems resulting from production of hydrogen sulfide during operation of this process.
