This Small Business Innovation Research (SBIR) Phase I project will engineer a fully automated, trailer-mounted Supersaturated Dissolved Oxygen Injector (SDOX) and determine the effects of addition of dissolved oxygen (DO) to impaired waterways. Waterways with low dissolved oxygen cannot support fish and other aquatic life and are dominated by anaerobic microbial digestive processes. If the amount of organic nutrients in a waterway is such that resulting bacterial populations consume oxygen at a rate higher than can be replenished to the system through natural aeration, then DO concentration is reduced until anaerobic conditions prevail. The potential utility of the SDOX unit ranges from remediation of waterways that have been impaired by long term exposure to organics (due to excessive or improper fertilization practices or other anthropogenic impacts) to emergency response for treatment of organic spills (from wastewater treatment facilities, animal waste lagoons, petroleum spills and the like). Currently, there are no practical methods to rapidly response to a spill of organics into a body of water. One of the most common organic spills is the accidental release of untreated grey water from a municipal wastewater treatment facility. As a result of the Clean Water Act, each state has mandated water quality parameters for the release of pollutants from any point source (such as wastewater treatment facilities). The development of the technology described in this proposal will provide a practical method to remediate spills that may be significantly less expensive than state imposed fines.

这个小型企业创新研究（SBIR）第一阶段项目将设计一个全自动的，拖车安装的过饱和溶解氧注射器（SDOX），并确定溶解氧（DO）添加到受损水道的影响。溶解氧低的水道不能支持鱼类和其他水生生物，主要是厌氧微生物消化过程。如果水道中有机营养物的量使得所得细菌群体以高于可通过自然曝气补充到系统的速率消耗氧，则DO浓度降低直到厌氧条件占优势。 SDOX装置的潜在效用范围从修复因长期暴露于有机物（由于过度或不适当的施肥实践或其他人为影响）而受损的水道到处理有机物溢出（来自废水处理设施、动物废物泻湖、石油溢出等）的应急响应。目前，还没有实用的方法来快速响应有机物泄漏到水体中。最常见的有机物泄漏之一是市政废水处理设施意外释放未经处理的灰水。由于《清洁水法》，每个州都规定了从任何点源（如废水处理设施）释放污染物的水质参数。本提案中所述技术的开发将提供一种补救溢油的实用方法，其成本可能大大低于国家征收的罚款。
