Design Basis for Enhanced Biological Phosphorus and Nitrogen Removal Wastewater Treatment Systems

9716144兰德尔奖是一个支持研究的奖项，其目的是为基于生物的废水处理工艺的设计提供比目前更合理的基础，该工艺有能力减少其流出物中的磷含量。这项研究涉及确定需要优选阶段以产生非挥发性脂肪酸的条件，并与处理过程的厌氧/反应阶段排除需要优选阶段的条件进行比较。这项研究的结果有望用于确定在何种条件下，优先处理是利用生物工艺强化废水除磷的必要步骤。这些知识有望用于改进基于生物的除磷工艺和系统的工程设计。与物理化学工艺相比，生物工艺在减少工艺残留量、改善残留物的脱水特性以及与生物反硝化工艺集成方面具有优势。***

9716144 Randall This is an award to support research the objective of which is to provide a more rational basis than now exists for design of biologically based wastewater treatment processes that have the capability for reducing the phosphorus content of their effluents. The research involves determination of conditions that necessitate the need for a prefermentation phase to produce nonvolatile fatty acids in comparison with conditions where the anaerobic/reaction phase of the treatment process precludes need for a prefermentation phase. Results of this research are expected to be used in determination of conditions under which prefermentation is a necessary step in enhanced removal of phosphorus from wastewater by use of biological processes. This knowledge is expected to be used in improving the engineering design of biologically-based, phosphorus removal processes and systems. Biologically-based processes have the advantage over physical-chemical processes in reducing the amounts of process residuals, improved dewatering characteristics of the residuals and capability of being integrated with biologically-based denitrification processes. ***
