Recovering energy and nutrients from the wastewater treatment process using Bioelectrochemical systems

废水含有能量，但我们花了更多的精力来处理它。如果你觉得这一说法不一致，那么这个博士将会很有兴趣，它将探索从废水中回收能量和养分。在一个必须满足严格监管的行业中，资产通常有50年的周期，要做出根本性的改变是困难的。创建一系列技术，每一种技术都能在它能以最佳方式工作的地方工作，这可能是一种允许应用新技术的方法。几个大型处理厂现在都有厌氧消化器来从污泥中回收能量，但在脱水这些污泥的过程中产生的液体含有极高的能量，其中含有有机物和营养物质。目前，这些液体被反馈到工厂的顶部重新进行处理，失去了已经浓缩的能量和营养。我们建议进行一项研究，对AD滤液中可以回收的东西进行经济评估，以及这可能有什么价值。然后，我们将探索可用于回收能量和营养的技术，特别是在生物电化学系统套件中。这些技术将在实验室和试点范围内开发，以期展示一种随后可用于处理厂的技术。

Wastewater contains energy, yet we spend even more energy getting rid of it. If you find this statement incongruous then this PhD will be of interest, it will explore energy and nutrient recovery from wastewater. In an industry that has to meet strict regulations, and assets have typically a 50 year cycle, making radical change is difficult. Creating a chain of technologies, each one working where it can work optimally is likely to the approach which will allow new technologies to be applied. Several large scale treatment plants now have anaerobic digesters to recover energy from sludge, but in dewatering this sludge a liquid is produced that is extremely high in energy containing organics and nutrients. Currently this liquid is fed back into the top of the works to re-undergo treatment, loosing the energy and nutrients that have been concentrated. We propose a study to conduct an economic assessment of what can be recovered from the AD filtrate, and what the value of this might be. We will then explore technologies, in particular in the suite of bioelectrochemical systems, which may be used to recover the energy and nutrients. These technologies will be developed in the lab, and at a pilot scale, with a view to demonstrating a technology that can then be implemented into the treatment works.
