New technologies for wastewater resource recovery by anoxigenic photoheterotrophic biological processes

对生物固体处理的严格规定和能源利用的增加增加了废水处理厂的运营成本，并降低了市政基础设施的可持续性。因此，废水处理行业正在从单纯的环境保护转向额外回收与水一起浪费的资源。在能量含量方面，可回收的有机物和营养物质（氮、磷）占人均用电量的15%左右；因此，恢复将提高可持续性并减少二氧化碳足迹。然而，利用目前的好氧生物过程进行恢复是有限的。因此，目前的项目将有助于开发新的厌氧生物过程，使回收成为可能。结果将提高基础设施效率，减轻纳税人的负担。

Tightening regulations on biosolids disposal and growing energy utilization increase the operational costs of wastewater treatment plants, and reduce the sustainability of municipal infrastructures. In response, the wastewater industry is converting from only treating wastewater for environmental protection to additionally recovering resources wasted with the water. In terms of energy content, recoverable organics and nutrients (nitrogen, phosphorus) account for ~15% of the per capita electricity consumption; accordingly, recovery will improve sustainability and reduce CO2 footprint. However, recovery using current aerobic biological processes is limited. Thus, the current program will contribute to the development of new anaerobic biological processes enabling recovery. The results will improve infrastructure efficiencies and reduce burden to tax payers.
