Recovering energy nutrients wastewater treatment

项目摘要

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.

废水中含有能量，但我们花费更多的能量来处理它。如果您发现这种说法不一致，那么这个博士学位将会很有趣，它将探索废水中的能量和营养物回收。在一个必须满足严格法规且资产通常有 50 年周期的行业中，进行根本性变革是很困难的。创建一系列技术，使每一项技术都在其能够最佳工作的地方工作，这可能是允许应用新技术的方法。一些大型处理厂现在拥有厌氧消化器来从污泥中回收能量，但在对污泥进行脱水时，会产生含有机物和营养物的能量极高的液体。目前，这种液体被送回到工厂顶部重新进行处理，失去了浓缩的能量和营养。我们提议开展一项研究，对 AD 滤液中可回收的物质及其价值进行经济评估。然后，我们将探索可用于回收能量和营养物质的技术，特别是生物电化学系统套件。这些技术将在实验室进行中试开发，以展示一种可以应用于处理厂的技术。
