项目摘要

DESCRIPTION (provided by applicant): This SBIR project addresses toxic and heavy metal exposure reduction through environmental contamination minimization via metal removal at the contamination source. Harmful metals which are not readily degraded or detoxified enter the environment in significant quantities via numerous industrial activities and frequently pose long-term environmental hazards. This Phase I program will develop a novel electrolytic technology for efficient aqueous source metal contaminant removal/recovery. The innovative cell design proposed will achieve higher removal efficiencies at lower contaminant concentrations, dramatically reduced fluid management power costs, and higher operating current densities allowing smaller and cheaper treatment units compared to conventional technology. Additionally several improvements to the approach will allow a much greater range of process optimization while enhancing both the cell and process robustness. The technology will work with a variety of common contaminants and mixtures thereof. The technology will be compact, reagentless, will require no feedstream pretreatment, and will recover the contaminant as a compact, pure, and potentially saleable product. Cell performance, stability, and design optimization will be explored with selected model contaminants. The results obtained will be used to develop treatment cost estimates, to design a prototype pilot-scale automated treatment system for Phase II implementation and subsequent field trial evaluation, and to perform feasibility analyzes against various contamination source scenarios. Target applications include treatment of: acid mine drainage, heavy metal and radionuclide contaminated sites, and metal contaminated industrial dragout/wash effluents and general discharges in operations such as electrowinning, metal manufacturing, plating, pickling, and circuit board manufacture operations being notable examples.

描述（由申请人提供）：该 SBIR 项目通过在污染源去除金属来最大程度地减少环境污染，从而减少有毒和重金属的暴露。不易降解或无毒的有害金属通过众多工业活动大量进入环境，并经常造成长期环境危害。该第一阶段计划将开发一种新型电解技术，用于有效去除/回收水源金属污染物。与传统技术相比，所提出的创新电池设计将在较低污染物浓度下实现更高的去除效率，显着降低流体管理电力成本，并提高工作电流密度，从而允许更小、更便宜的处理单元。此外，对该方法的一些改进将允许更大范围的工艺优化，同时增强电池和工艺的稳健性。该技术适用于各种常见污染物及其混合物。该技术将是紧凑的、无试剂的，不需要进料流预处理，并且将污染物回收为紧凑的、纯净的和潜在可销售的产品。将使用选定的模型污染物来探索电池性能、稳定性和设计优化。获得的结果将用于制定处理成本估算，设计用于二期实施和后续现场试验评估的原型中试自动化处理系统，并对各种污染源情景进行可行性分析。目标应用包括处理：酸性矿井排水、重金属和放射性核素污染场地、金属污染的工业拖出/洗涤废水以及电解冶金、金属制造、电镀、酸洗和电路板制造等操作中的一般排放物，这些都是著名的例子。
