Development of a sustainable and effective oxidation technology for wastewater treatment

摘要：该跨学科项目旨在为包括生活和工业废水在内的废水处理提供一种安全可靠的技术。为了实现这一目标，将开发一种将光催化氧化和吸附过程相结合的新技术。在整个学生期间，来自Dryden Aqua的科学投入和资金支持将确保该项目的可行性和有效性。背景：在过去20年中，废水处理得到了显著改善，英国大部分地表水现在都处于良好的生物和化学质量。然而，处理达到这一标准的废水所需的能源很高；能源用于收集、处理和排放废水以及管理污水污泥。毫无疑问，随着我们对清洁水的需求增加，安全地将废水排放到环境中所需的能源总量也在增加。由于传统的废水处理过程是能源密集型的，因此不环保，未来的战略应侧重于减少能源需求，使能源处理需求从零到负，以创造经济激励，并使发达国家和发展中国家都能够获得可持续的卫生设施。Dryden Aqua最近展示了新型吸附材料，它可以通过加倍性能成功地取代传统的砂过滤器。然而，持久性和外来污染物，如药品、微塑料、洗涤剂和其他新出现的污染物，不能通过传统技术有效地去除。近几年的研究已经证明，光催化氧化技术可以有效地降解废水中的持久性和有毒污染物。光催化是基于使用光和催化剂将污染物氧化成安全的最终产品。该项目是独一无二的设计，旨在通过使用新型干胶材料与光催化工艺相结合，实现超出最先进水平的重大技术步骤，为废水处理提供一种综合、低成本和高效的方法。我们最近在光催化氧化和水处理方面的发现[5]将进一步推进，以达到饮用水处理的质量标准。目标：提供一种新的强大的技术，能够作为水和废水处理的三级处理抛光方法，以去除有害的持久性有机污染物以及优先考虑的物质，如微塑料

Abstract: This interdisciplinary project aims to provide a safe and reliable technology for thetreatment of wastewater including domestic and industrial effluents. To achieve this, a noveltechnology will be developed by combining photocatalytic oxidation with adsorptionprocesses. Scientific input and financial support from Dryden Aqua during the whole durationof the studentship will safeguard the feasibility and effectiveness of the project.Background: Wastewater treatment has improved significantly over the past 20 years, withmost of UK surface waters now being in good biological and chemical quality. However, theenergy required to treat wastewater to this standard is high; with energy being used to collect,treat and discharge wastewater and manage sewage sludge. There is no doubt that as ourdemand for clean water increases, so does the total amount of energy needed to safelydischarge wastewater into the environment. Since conventional wastewater treatmentprocesses are energy-intensive and hence not environmentally friendly, future strategiesshould focus on reducing energy demands and enabling zero to negative energy treatmentrequirements, as to create economic incentives and enable access to sustainable sanitationin both developed and developing communities.Dryden Aqua has recently demonstrated novel adsorption materials that can successfullyreplace conventional sand filters by doubling their performance. Nevertheless, persistent andxenobiotic pollutants, such as pharmaceuticals, microplastics, detergents, and other emergingcontaminants, cannot be effectively removed by conventional techniques. Over the last fewyears, research has proven that photocatalytic oxidation technology can effectively degradepersistent and toxic pollutants from wastewater. Photocatalysis is based on the use of lightand a catalyst to oxidize pollutants to safe final products. This project is uniquely designed tomake significant technological steps beyond the state-of-the-art by using novel Drydenmaterials in combination with photocatalytic processes to provide an integrated, low cost andefficient method for wastewater treatment. Our recent discoveries in photocatalytic oxidationand water treatment [5] will be further advanced to meet the quality standards for drinkingwater treatment.Objectives: To deliver a new robust technology able to serve as a tertiary treatment polishingmethod for water and wastewater treatment to remove hazardous persistent organic pollutantsas well as priority substances such as micro-plastics
