SBIR Phase II: Application of Induction Accelerators for Electron Beam Radiolysis of Contaminated Water

*** 9531275 Moran这个小企业创新研究二期项目处理在许多地方的地下水和废水中以不可接受的高浓度存在的有毒和传染性污染物。虽然废水中的许多有毒污染物在处理之前必须降低到十亿分之一的浓度，但对于工业过程中的水回收来说，更适度的降低是合适的。这项由科学研究实验室开展的小型企业创新研究二期项目将应用一种紧凑、低成本、全固态感应加速器技术来破坏废水中的有毒有机污染物和工业生产用水，使其适用于生产用水的循环利用。在这项研究的第一阶段，科学研究实验室能够证明在添加和不添加氧化增强剂、过氧化氢和溶解氧的情况下有效和高效地破坏苯和甲苯。科学研究实验室现在能够奠定基础，以便在中试规模上快速实施基于电子束辐射分解的感应加速器水净化系统。中试规模是在科学研究实验室目前的nomad - iv加速器的设计参数范围内。成本研究表明，该技术优于所有竞争性修复处理，特别是在污染物浓度超过50 ppm时。固态电路、模块化、可扩展性和紧凑性的优势提供了比传统电子束系统更多的技术优势。苯的破坏效果可达3 ~ 4个数量级。效率与传统的静电电子加速器相比要好得多。过氧化氢的加入提高了约37%的破坏效率。这些效率的提高大大降低了成本。该项目有可能提供一种具有成本效益的处理方法，不仅可以改善废水的质量，而且还可以通过促进工业过程中水的循环利用，从而消除一个主要的污染源，大大减少或消除向环境排放的废水。美国环境保护署估计，1989年美国工业处理了350亿加仑的剧毒废水，耗资20亿美元。SRL的新型感应加速器可能会占据5%或更多的市场份额，年总收入将达到1亿美元。由于用水密集型的纸浆和造纸工业每天排放的废水量要大得多，达到42.5亿加仑，因此SRL将首先以该行业为试点。＊＊＊

*** 9531275 Moran This Small Business Innovation Research Phase II project deals with toxic and infectious contaminants which are present in unacceptably high concentrations in groundwater and in wastewater in many locations. While many toxic contaminants in wastewater must be reduced to concentrations on the order of parts per billion prior to disposal, a more modest reduction is appropriate for industrial in-process water recycling. This Small Business Innovation Research Phase II project from Science Research Laboratory will apply a compact, low cost, all-solid-state induction accelerator technology to the destruction of toxic organic contaminants in wastewater and to industrial process water so that it is made suitable for in-process water recycling. In the first phase of this research, Science Research Laboratory was able to demonstrate effective and efficient destruction of benzene, and toluene with and without addition of oxidizing enhancers, hydrogen peroxide and dissolved oxygen. Science Research Laboratory is now in a position to lay the groundwork for rapid implementation of an induction-accelerator-based water decontamination system based on electron beam radiolysis on a pilot scale. Pilot scale is within the design parameters of the current SNOMAD-IV accelerator at Science Research Laboratory. Cost studies show this technology is superior to all competing remediation treatments, especially at contaminant concentrations above 50 ppm. Advantages of solid state circuitry, modularity, scalability, and compactness offer additional technical advantages over conventional electron beam systems. Benzene destruction was effective to three or four orders of magnitude. Efficiencies compare well to those of conventional electrostatic electron accelerators. Peroxide addition improves destruction efficiency by approximately 37%. There are important cost reductions associated with these efficiency gains. This project has the potential to provide a cost-effective treatmen t which will not only improve the quality of effluent water but may also greatly reduce or eliminate wastewater discharge to the environment by facilitating industrial in-process water recycling and thereby removing a major source of pollution. EPA estimates 35 billion gallons of highly toxic wastewater was treated by U.S. industries in 1989 at a cost of $2 Billion. SRL's novel induction accelerator may capture 5% or more of this market to provide annual gross revenues of $100 million. Since the water intensive pulp and paper industry discharge even much larger volumes of wastewater, 4.25 billion gallons daily, SRL will first target this industry on a pilot scale. ***
