Interactions between plants and faecal pathogens in urban water treatment: significance of soil microbes, plant debris, root exudates and rhizosphere

重要的是在雨水和废水中的病原体释放到下游娱乐沃茨或收获之前对其进行处理。在水处理中使用植物可以改善对人类和生态系统健康所关注的污染物的去除。然而，产生这种改善的确切机制仍然未知，这对于粪便病原体去除尤其如此。这个项目将提高我们对根系、其分泌物、植物残体和土壤微生物在城市水处理系统中去除粪便病原体的相互作用的理解。通过这种理解，该项目将导致优化的低能耗，低技术和低维护的处理系统。

It is important to treat pathogens in stormwater and wastewater before release into downstream recreational waters or harvesting. Using plants in water treatment improves the removal of pollutants of concern to human and ecosystem health. However, the exact mechanisms which generate this improvement remain unknown, and this is especially true for faecal pathogen removal. This project will enhance our understanding of the interactive role that roots, their exudates, plant debris and soil microbes play in faecal pathogen removal in urban water treatment systems. Through this understanding, this project will lead to optimised low-energy, low-tech and low-maintenance treatment systems.
