Speech Title：Water environment comprehensive regulation and ecological restoration

Abstracts: The report "Water environment comprehensive regulation and ecological restoration" is based on the current water environment background of water disaster intensification, water resource shortage, water environment pollution, water ecological degradation, water landscape destruction. Based on the relationship between city and water, the comprehensive water environment regulation strategy is proposed from different dimensions such as urban pipe network construction, urban water body treatment and watershed water body treatment, which would promote the development of urban water environment comprehensive treatment from a single flood control and drainage, landscape beautification, to a multi-dimensional integration of security, ecology, and economy. The report highlights the important role of ecological restoration in the comprehensive management of water environment. With ecological concepts, methods and technologies as the core, advanced technologies such as green road, ecological floating island and ecological slope protection are comprehensively applied to create diversified ecological environment types, establish multi-level stable biological populations and structures, and achieve sustainable development of water environment. Finally, with the actual case as evidence, Guangfo New World Manor and Dongguan Qingxi River as typical urban community and watershed governance models, respectively, to explore their comprehensive water pollution treatment strategies and water environment comprehensive governance models, providing reference and guidance for future urban water environment comprehensive governance.

Speech Title：The direct effect of elevated carbon dioxide on denitrification in sediments and its mechanism

Abstracts: The CO2 concentration in soil microenvironment and Carbon Capture and Storage (CCS) site was 10 to 100 folds of the atmospheric one. Therefore, the increase in carbon dioxide will bring challenges to the living organisms on Earth. Microbial denitrification is an important step in reducing nitrate to nitrogen and maintaining nitrogen balance in the nitrogen cycle. However, the direct effect of elevated CO2 on denitrifying organisms and denitrification processes has seldom been reported. This presentation reported the direct impact of elevated CO2 concentration on denitrification in sediments and explored its mechanism. It was observed that the microbial denitrification in estuarine sediments was inhibited with the increase of CO2, but intermediates (NO2--N and N2O-N) were accumulated. Further investigation with P. denitrificans as model denitrifying bacteria showed that CO2 significantly inhibited bacterial growth and cell viability. Also, the transmembrane transport of carbon source (acetate) was inhibited by decreasing the driving force for acetate transport, which reduced the generation of NADH. In addition, the increase of CO2 inhibited nitrate metabolism and caused the accumulations of NO2--N and N2O-N, which was attributed to the suppression of CO2 on electron transport and consumption proved by the down-regulated expression of proteins and gene of key proteins, such as flavoprotein, succinate dehydrogenase, cytochrome, nitrate reductase (NAR), nitrite reductase (NIR), nitric oxide reductase (NOR), and nitrous oxide reductase (N2OR). These results provided new insight into the effects of CO2 on bio-denitrification.

Speech Title：Key technologies in biological purification of VOCs gases and their full-scale applications

Abstracts: Volatile organic compounds (VOCs) in the ambient air play an important role in the formation of particulate matter and ozone, thereby affecting air quality. Industrial waste gases contribute largely to the VOCs emissions, and different end-of-pipe methods have been developed to control such emissions. Among these methods, biotechnology is suitable for treating low-concentration VOCs with almost no secondary pollutants generated. However, the application of biotechnology may be limited by some inherent properties of different VOCs, such as hydrophobicity and poor biodegradability. In this presentation, we share our research progress on key technologies for improving VOCs removal using biotechnologies, including development of bioactive functional materials, enhancement of mass transfer, use of coupled chemical-biological process and establishment of novel bioelectrochemical systems.

Speech Title：Unlocking Tomorrow's Clean Water: Challenges and Promising Pathways in Emerging Contaminant Management

Abstracts: Microplastic, pesticides, personal care items, cosmetics, and medications are just a few of the various compounds that fall under the heading of emerging contaminants (ECs). These ECs, which pose serious risks to the environment and public health, have penetrated groundwater, surface water, and wastewater systems at alarming rates as a result of booming enterprises. Water sources have been contaminated as a result of agricultural practices that extensively rely on pesticides and herbicides, accumulating dangerous substances in aquatic species. Similar to the increased usage of cosmetics and personal care items containing synthetic substances, ECs are now found in drinking water supplies. Additionally, it has come to light that pharmaceuticals significantly contribute to EC pollution. This chemical buildup exerts adverse effects on aquatic ecosystems, ranging from disruptions in reproductive systems to behavioral alterations. Moreover, human exposure to ECs has been linked to various health issues, including cancer, reproductive disorders, and developmental abnormalities. Consequently, urgent measures are imperative to curtail EC release into the environment through enhanced regulation and management practices.The ability to partially remove EC has been demonstrated using conventional wastewater treatment techniques such as activated sludge, membrane filtration, coagulation, adsorption, and ozonation. With the goal of recovering valuable molecules from wastewater, groundwater, and surface water, recent research has focused on creating effective methods for locating and eliminating these pollutants from wastewater. However, detailed knowledge of many of these new contaminants is still lacking, and the majority are currently unregulated.This study focuses on innovative remediation strategies capable of efficiently eliminating these contaminants from polluted sites. Promising methods include phytoremediation, bioremediation, and nanotechnology-based approaches. In conclusion, this research underscores the necessity of ongoing investigations into novel approaches to identify and mitigate EC risks, safeguarding both human health and the environment.
