The accumulation of plastics in the aquatic environment is a global issue of emerging concern. Small plastic particles known as microplastics (MP) represent about 92% of the total plastic waste. Many organisms can ingest MP, which are eventually transferred to humans through food chain. MPs can cause toxic and adverse effects on organisms, including endocrine disruption, mortality, delayed ovulation, and hepatic stress.Advanced oxidation processes (AOPs) have been proved effective for the treatment of such biologically recalcitrant pollutants. The key advantage of AOPs is that they generate, in-situ, reactive oxygen species, which, in turn, react with the pollutants and eventually mineralize them to safe final products. Using an appropriate AOP as a pre-treatment to conventional biological treatment can lead to partial mineralization of organic content, accompanied with detoxification and biodegradability improvement of the treated effluent.The aim of this project is to explore and develop new sustainable and efficient technologies to remove microplastics from water and wastewater.

塑料在水环境中的积累是一个新出现的全球问题。被称为微塑料(MP)的小塑料颗粒约占塑料垃圾总量的92%。许多生物可以摄取MP，最终通过食物链传播给人类。MPS可对生物体造成毒性和不良影响，包括内分泌干扰、死亡、排卵延迟和肝脏应激。高级氧化工艺(AOPS)已被证明是处理这些生物顽固性污染物的有效方法。AOPS的主要优势是，它们在现场产生活性氧物种，这些活性氧物种反过来与污染物反应，最终将它们矿化成安全的最终产品。采用合适的AOP作为常规生物处理的前处理，可以使有机物部分矿化，同时处理后的出水解毒和可生化性提高，本项目的目的是探索和开发可持续高效的新技术来去除水和废水中的微塑料。
