Evaluation of Rotating Biological Contactor Technology for Civil Works Recreational Areas

摘要

The objective of this study was to investigate the applicability of rotating biological contactor (RBC) technology for treating wastewaters generated at typical U.S. Army Corps of Engineers recreation areas. This report outlines selection criteria for civil works personnel who must decide whether to use RBCs, provides RBC case histories for use at Corps recreational areas, and presents guidance to ensure that RBC use is both economical and compatible with the Corps' needs. These objectives were accomplished in four steps: Corps district and division personnel, and pollution abatement engineers familiar with recreational area wastewaters were surveyed. Visits were made to Corps recreational areas, and to sites which were operated and maintained by various State and National Park Service districts, and which used RBC technology; The literature on RBC technology was reviewed; An evaluation and economic comparison were done for RBC technology and older treatment alternatives, such as package extended aeration, lagoons, septic tanks, leaching fields, oxidation ditches, and land treatment, and Preliminary design guidance and a procedure for selecting RBC technology were developed for Corps recreational areas.
