Abstract

A study was conducted to evaluate the performance of six advanced wastewater treatment facilities using biological nutrient removal processes as the primary mechanism for removing carbon, nitrogen, and phosphorus from domestic wastewater. One year of operating data was obtained from monthly operating reports provided by the Georgia Environmental Protection Division (EPD) in Atlanta. Additional information about facility operations and the types of chemicals used was gathered through review of EPD files and interviews with plant personnel. Data evaluated were: influent and effluent five-day Biochemical Oxygen Demand (BOD(5)); influent and effluent total suspended solids (TSS); influent Total Kjeldahl Nitrogen and effluent Total Nitrogen; and influent and effluent Total Phosphorus (TP). Although varying from plant to plant, effluent requirements for BOD(5), TSS, ammonia, and TP were met. Chemicals utilized, design capacity, and monthly effluent concentrations are presented in this study.

摘要

开展了一项研究，以评估六个采用生物营养物去除工艺作为从生活污水中去除碳、氮和磷的主要机制的先进污水处理设施的性能。从亚特兰大的佐治亚州环境保护部（EPD）提供的月度运营报告中获取了一年的运营数据。通过查阅EPD文件和与工厂工作人员面谈，收集了有关设施运营和所使用化学品类型的更多信息。评估的数据包括：进水和出水的五日生化需氧量（BOD(5)）；进水和出水的总悬浮固体（TSS）；进水凯氏氮和出水总氮；以及进水和出水的总磷（TP）。尽管各工厂情况不同，但均满足了对BOD(5)、TSS、氨和TP的出水要求。本研究介绍了所使用的化学品、设计能力和月度出水浓度。
