Summary: The study aims to maximize the mass yield, higher heating value, and energy yield of food waste through optimizing the operational variables of hydrothermal carbonization process. It is found that temperature and reaction time have a significant impact on the fixed carbon and carbon percentage of hydrochar. The combination of process water and hydrochar under optimal conditions yields the highest methane production.

Summary: Anaerobic co-digestion is an important technology for processing organic waste, recovering nutrients, and creating sustainable biofuel. However, the low biogas output and high installation costs limit its viability. This literature review demonstrates that anaerobic co-digestion produces more methane biogas than anaerobic digestion, and adjusting the waste-to-water waste ratio can increase methane production.

Summary: Anaerobic digestion of food waste appears to be a promising method for generating biogas in the face of increasing energy demand and the circular economy. It causes less air and solid waste pollution compared to other methods such as incineration, gasification, and pyrolysis. Research on biogas production mainly focuses on substrate performance, with limited investigations on the environmental impact of anaerobic digestion.

Summary: This study investigated the effect of co-digestion of food waste (FW) with kitchen waste (KW) or garden waste (GW) on biogas production and organic loading rate. The results showed that co-digestion increased biogas production and improved the tolerance to higher organic loading rate by mitigating ammonia nitrogen inhibition and volatile fatty acids accumulation.

Summary: This study evaluated the effect of alternative filtering materials and bed aeration on the retention of nutrients and fecal bacteria in woodchip bedded stand-off pads for cows. The results showed that the alternative biofilters were more efficient in removing COD, SS, TN, and NO3-N, while conventional biofilters were more efficient for PO4-P removal. Aeration did not have a significant effect under the tested temperature conditions.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: In this study, an electron beam excitation multi-wavelength ultraviolet (EBE-MW-UV) system was established and found to have significantly higher microbial inactivation effects compared to single-wavelength UV-LEDs in water. Mechanism analysis revealed that EBE-MW-UV damaged microbial DNA and proteins, and generated additional reactive oxygen species, leading to microbial inactivation.

Summary: This study focuses on the development of an air-lift bio-electrochemical reactor (ALBER) with a continuous feeding regime to enhance nitrogen removal from synthetic wastewater. The effect of temperature, hydraulic retention time (HRT), N -NH+4 /TN ratio, and current density on the reactor performance was investigated, and the ALBER achieved a maximum TN removal of 73%. The results suggest that the ALBER has potential for treating industrial wastewater at low temperatures.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
