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

废水含有能量，但我们要花费更多的能量来处理它。如果你觉得这个说法不协调，那么这个博士学位将会感兴趣，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要求、资产周期通常为50年的行业，进行彻底变革是很困难的。创建一个技术链，每一个技术都在它可以最佳工作的地方工作，这可能是允许新技术应用的方法。一些大型处理厂现在有厌氧消化器来从污泥中回收能量，但在脱水污泥的过程中产生的液体含有极高的能量，含有有机物和营养物质。目前，这种液体被反馈到作品的顶部重新进行处理，失去了已经集中的能量和营养。我们建议进行一项研究，对从AD滤液中可以回收的东西进行经济评估，以及这可能是什么价值。然后，我们将探索技术，特别是生物电化学系统套件，可用于回收能量和营养物质。这些技术将在实验室开发，并以试点规模进行，目的是展示一项技术，然后在滤水厂实施。

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.
