Title: Sustainable solid and liquid waste treatment through utilization for circular economy development

Abstract: There is a clear and urgent need for effective and efficient management of all kinds of wastes including animal wastes, municipal liquid and solid wastes like waste plastics, due to increasing clean water demand and environment pollution concerns world-wide. There are also increasing interests in sustainable circular economy development. Therefore, tremendous effort has been put into researching and developing necessary technologies to support the development and applications. Complete recycling and utilizing solid and liquid wastes technologies are key to the sustainable circular economy practice. There is a great potential to recover large amounts of energy, chemicals, nutrients, and water from solid and liquid wastes. For wastewaters, treatment and disposal has been the primary management strategy, although treatment through complete utilization has gained ground in recent years. Recycling, composting, combustion, and landfilling have been the main solid wastes management strategy. While many technologies have been developed and applied in waste management, there are still tremendous needs to improve them and develop new technologies in order to promote circular economy at all levels. In this presentation, new biorefining model and development in sustainable technologies will be presented and highlighted, which have the potential to maximize use and minimize disposal of solid and liquid wastes. The model and novel technologies include 1) new anaerobic digestion and biochar based filtration for processing of liquid waste streams, combining with photocatalysis and algae and aquaponic cultivation systems to completely treat and utilize manures using a multi-stage approach consisting of following processes: a novel anaerobic digestion (AD) with pretreatment for C:N adjustment, and ammonia and hydrogen sulfide reduction to improve methane and nitrogen fertilizer production; an advanced microalgae cultivation to recover nitrogen, phosphorus, and COD in the remaining wastewater after AD and at the same time produce algal biomass as animal and fish feed or for biofuels production; and a hydroponic system to further reduce nutrients and pollutants in the post-microalgae culture broth. Additional biochar filtration steps between above main stages are used to condition the effluent for further utilization or recycling and discharge. 2) novel catalytic microwave assisted pyrolysis and gasification of solid wastes including used biochar and other solid residues such as waste plastics to enable capture of energy and recycle of chemicals and materials and hence complete utilization of solid wastes. Recommendation for further research and development will also be discussed.

Title: Water rock interaction mechanism and environment deterioration trend in group coal mining area

Abstract: Long-term large-scale coal mining in China has caused the abnormal groundwater chemical field and serious water environment deterioration, and the rapid increase of mine closures has exacerbated the problem. In view of the difficulties in the assessment and control of aquifer structure and groundwater flow field change in group coal mining area on groundwater chemical field, this proposal focused on two key scientific problems, one is the coupled process of hydrodynamic field and hydrochemical field driven by aquifer structure change, the other is the multiphase transformation mechanism environment sensitive elements excited by closed mines. Through field investigation and indoor physical simulation of water rock geochemistry simulation and multi-field and multi-phase hydrochemical coupled numerical simulation, the roof aquifer structure change impacted water rock interaction mechanism, water chemical effects of groundwater pumping on the floor limestone groundwater chemistry, the change of oxidation - reduction binary water chemical environment driven by closed coal mines, as well as the group coal mining driving environmental effect of space-time coupling mechanism of water chemical field, eventually to reverse the group coal mining area of water environment deterioration trend, and provide the scientific basis for regional economic and social sustainable development.

Title: The impact of modern coal mining activities on the environment and control

Abstract: The topic of my report is "the impact of modern coal mining activities on the environment and control", which mainly refers to the impact of modern coal mining activities on surface subsidence and water resources. The control measures include the protection of surface subsidence and water resources by non- pillar mining and backfilling mining, as well as the future research content and the achievement target.
