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

* 9531275莫兰 这个小企业创新研究第二阶段项目涉及有毒和传染性污染物，这些污染物在许多地方的地下水和废水中的浓度高得令人无法接受。 虽然废水中的许多有毒污染物在处置前必须降低到十亿分之几的浓度，但对于工业过程中的水回收来说，更适度的降低是合适的。 来自科学研究实验室的小型企业创新研究第二阶段项目将采用紧凑，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工艺用水，使其适用于过程中水回收。 在这项研究的第一阶段，科学研究实验室能够证明有效和高效的破坏苯，甲苯和氧化增强剂，过氧化氢和溶解氧的添加和不添加。 科学研究实验室现在能够奠定基础，快速实施一个感应加速器为基础的水净化系统的基础上，电子束辐解的试点规模。 中试规模在科学研究实验室目前的SNOMAD-IV加速器的设计参数范围内。 成本研究表明，该技术上级所有竞争性补救处理，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点提供了优于常规电子束系统的附加技术优点。 苯的破坏是有效的三个或四个数量级。 与传统的静电电子加速器相比，其效率更高。 添加过氧化物可将销毁效率提高约37%。这些效率的提高带来了重要的成本降低。 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的水循环利用来大大减少或消除废水排放到环境中，从而消除主要的污染源。 美国环保署估计，1989年美国工业界处理了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，每年的总收入为1亿美元。 由于水密集型纸浆和造纸行业排放的废水量更大，每天42.5亿加仑，SRL将首先针对该行业进行试点。 ***

*** 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. ***
