SEWER ODOUR ABATEMENT PRACTICES - AN AUSTRALIAN SURVEY

摘要

A survey of nine Australian wastewater utilities was undertaken to assess current sewer network odour abatement practices. The survey results indicated that activated carbon based systems are the most common followed by biofilters, and that most processes are treating passive emissions from the sewers. Most abatement processes are not being routinely maintained and are monitored solely through community complaints. Activated carbon media is generally replaced in a reactive manner. H_2S is the dominant online and offline monitoring parameter with limited use of non-H_2S odorant analysis. There were significant limitations in the industry's ability to provide fundamental process data.
