Newton Fund - Novel UV-assisted catalytic process for the treatment of Brazil wastewater and reuse

2007年，巴西人均可用水量达到43027立方米/年，高于同年世界人均8209立方米的平均水平。然而，分布非常不均匀，主要沿海城市，如里约热内卢、圣保罗和累西腓，受到上游居民和工业污水污染的影响，污染了河流、湖泊和海洋。2000年，收集到的废水中只有35%得到了处理。该项目是为巴西一家污水处理公司开发和推广一种具有成本效益、低能耗的英国污水处理和水再利用创新技术解决方案。待开发的技术是在一种新型反应器设计中，在催化网状氧化过程中添加紫外线辅助，以降解顽固污染物，如表面活性剂，石化产品和农药。环境友好型过氧化氢在室温下将污染物氧化成无害的可生物降解的有机酸或二氧化碳和水。将优化处理时间，以满足特定水回用的要求。

In 2007, per capita water availability in Brazil reached 43,027 m3 per year, above the world average of 8,209m3 per capita in the same year. However the distribution is very uneven with major Coastal cities such as Riode Janeiro, São Paulo and Recife suffer effects of upstream residential and industrial sewage contaminatingfeeder rivers, lakes, and the ocean. In 2000, only 35% of collected wastewater received any treatment. Thisproject is the development and roll-out of a ost effective, low energy UK innovative technology solution towastewater treatment and water reuse to an established Brazilian Wastewater treatment company. Thetechnology to be developed is to add UV assistance to a catalytic mesh oxidation process in a novel reactordesign to degrade recalcitrant pollutants, e.g. surfactants, petrochemicals and pesticides. Environmentallyfriendly hydrogen peroxide is used at room temperature in the process to oxidise pollutants to harmlessbiodegradeable organic acids or carbon dioxide and water. Treatment duration will be optimised to meet therequirements of the specific water reuse.
