SBIR Phase I: A Portable Dissolved Oxygen Delivery System for Rapid Treatment of Organic Spills

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、拖车安装的过饱和溶解氧注射器(SDOX)，并确定向受损水道添加溶解氧(DO)的影响。低溶解氧的水道无法养活鱼类和其他水生生物，以厌氧微生物消化过程为主。如果水道中的有机营养物的数量使得产生的细菌种群消耗氧气的速度高于通过自然曝气补充到系统中的速度，那么DO浓度就会降低，直到厌氧条件占上风。SDOX装置的潜在用途从修复因长期暴露于有机物(由于过度或不当的施肥做法或其他人为影响)而受损的水道，到处理有机泄漏(来自废水处理设施、动物粪便泻湖、石油泄漏等)的紧急反应。目前，还没有实用的方法来对泄漏到水体中的有机物做出快速反应。最常见的有机泄漏之一是市政污水处理设施意外泄漏未经处理的灰水。作为《清洁水法》的结果，每个州都规定了从任何点源(如废水处理设施)排放污染物的水质参数。这项提案中描述的技术的发展将提供一种实用的方法来补救漏油，这种方法可能比国家征收的罚款要便宜得多。

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.
