This project focuses on solving the problems of high organic nitrogen wastewater treatment in petrochemical and chemical industries. In response to the international net-zero emission trend, it aims to develop innovative technologies characterized by low pollution, low energy consumption, low cost, and low space. The COAC catalytic oxidation technology, when combined with various pretreatment methods, significantly enhances catalyst lifespan and efficiency. It is particularly suitable for treating high-concentration refractory organic wastewater and offers the advantage of zero sludge production. For organic nitrogen wastewater, it achieves extremely low conversion rates of ammonia nitrogen and nitrate nitrogen. Additionally, the PVA bio-pellet technology, compared to conventional biological treatment, reduces sludge production by over 70%. For sewage and other organic nitrogen industrial wastewater, intermittent
aeration operations can lower electricity costs while effectively reducing ammonia nitrogen conversion rates, thereby decreasing the alkalinity chemical dosing required in the nitrification process. The demonstration was applied to Yilan's Chemical Industry and Tainan's Film Manufacturing Industry, achieving a COD removal rate of more than 80%, and effectively reducing carbon emissions and operating costs.
Non-thermal plasma technology has also been developed to treat persistent organic pollutants (e.g., PFAS and pharmaceutical residues). It has the characteristics of small equipment, no need to add chemicals, and can remove more than 90% of pollutants. At the same time, it integrates a micron bubble reaction module, which has been proven to have high efficiency and low carbon emissions in hospital wastewater actual plant tests, significantly better than traditional treatment methods.
In response to the challenges posed by climate change, Taiwan and India have forged a partnership in the field of water environment technologies. With India facing an urgent need to improve its drinking water and wastewater treatment infrastructure, Taiwan has stepped in with advanced solutions to support India's journey toward sustainable development. In May, both nations convened a virtual "Sustainable Water Environment Technology Exchange" conference, focusing on industrial pollution control within the Clean Ganga Project. In June, a Taiwanese delegation visited India, engaging with government agencies, leading companies, and research institutions to gain insights into local market needs. This collaboration culminated in September with the "Taiwan-India Sustainable Water Environment Forum," which included conferences, site visits, and technical exchanges. The initiative successfully fostered connections across Taiwanese and Indian industries, government bodies, academia, and research organizations, paving the way for joint efforts in water resource management and sustainable development.
Our team has also completed on-site interviews and guidance for six companies, organized expert consultation meetings, conducted performance achievement visits, and published results in journals and conferences to promote the three green processing technologies developed under this project.
