STTR Phase I: Ultraviolet Activated Chelation (UVAC) for the Recovery of Hg from Industrial Wastewater

这个小企业技术转让第一阶段项目的重点是开发一种先进的氧化技术，以满足目前和即将出台的关于工业废水中可能排放的汞浓度的法规。在目前的项目中，将使用一种专有的光催化剂来研究氧化和去除汞的能力。该项目的研究目标将是更好地了解去除过程，优化使用这种方法去除汞的效果，并确定未来发展所需的参数。通过提议的方法，预计汞浓度将低于100毫帕。该方法具有从各种不同的废物流中去除汞的稳健性，并且比传统的水处理技术需要更少的o&m成本。汞排放，无论是来自空气排放还是工业废水，都严重威胁着生态系统和渔业。通常，环保技术被视为符合环境要求的必需品，而不会对其利润表产生积极影响。拟议的方法可能会改变这种观点；这个过程可能会从烧碱中去除汞，烧碱是工业的一种商品。

This Small Business Technology Transfer Phase I project focuses on developing an advanced oxidation technology to meet current and pending regulations for concentrations of mercury that can be emitted in industrial wastewaters. In the current project, a proprietary photocatalyst will be used to investigate the ability to oxidize and remove the Hg. The research objectives of this project will be to better understand the removal process, to optimize the removal of mercury using this approach, and to define the parameters necessary for future development. Mercury concentrations below 100 ppt are anticipated via the proposed approach. The approach has the robustness to remove Hg from a variety of different waste streams and requires less O&M costs than traditional water treatment technologies. Mercury emissions, whether originating from air emissions or industrial effluents severely threaten the ecosystem and the fishing industry. Typically, environmental technologies are viewed as necessities for environmental compliance, and not as positively impacting their profit statements. The proposed approach can potentially alter this view; this process could possibly remove Hg from caustic, a commodity product for the industry.
