摘要：

The 2-year study by Hampton Roads Sanitation District to evaluate methods to eliminate off-site plant odors resulting from a force main collection system produced the following results: Hydrogen peroxide addition was effective but very expensive. Ferrous sulfate addition was undesirable because of poor performance and high cost. Upline chlorination was not effective. Upline bacterial culture addition was not effective. Pre-chlorination was effective; however, both chemical cost and chemical supply make it unattractive. Pre-aeration can effectively oxidize 80% of the influent sulfides; the remaining 20% are released with the air stream. Sulfides in the air stream can be removed using a packed-tower scrubber. Three chemicals that can be used with the packed-tower scrubber are hypochlorite, chlorine solution, and caustic. Of the three chemicals, caustic was the most cost-effective and easiest to control. Based on this study, design criteria were developed and used to design odor control facilities at the six treatment plants associated with this study.
