Hydrologic and water quality modelling of bioretention columns in cold regions

Hydrological Processes (2023)

Yang Yu Zhuowen Li Tong Yu Shuai Guo Yongchao Zhou

Abstract Bioretention is widely used in urban sustainable stormwater management; however, limited numerical research has been conducted on its performance in cold regions, particularly for winter snowmelt, spring runoff and summer large storms (>50 mm) for urban flood mitigation. In this study, HYDRUS 1D was used to explore these knowledge gaps. The model was comprehensively calibrated and validated against 2‐year hydrologic and water quality data of four bioretention columns with different designs under lab‐simulated cold region conditions. The Morris method was used to measure the sensitivity and interaction of the calibrated hydraulic parameters. The model revealed that the effective hydraulic conductivity ( K S ) values of the soil media were similar for winter snowmelt and spring runoff when the soil temperature was around −0.5°C. Preferential flow is likely to occur in soil media during winter or spring in cold regions. The summer modelling showed that bioretention could substantially reduce peak flow, ponding depth and duration for large storm events (even for a 1:100 local storm with 83.4 mm in 4 h). The water quality modelling confirmed experimental results that the bioretention effectively removed phosphate and ammonium but had leaching issues for chloride and nitrate. Finally, optimization and recommendations for bioretention columns were provided.

Litchi pericarps used as adsorbents for methylene blue removal from solution

Desalination and Water Treatment (2014)

Xinge Pan Xiaochen Li Jili Yang Shujuan Sun Jiyu Tian

The adsorption capacity of methylene blue (MB) on raw or chemically modified litchi pericarp (LP or MLP, respectively) was investigated as a function of contact time, pH, and adsorbent dose. The adsorption isotherms, kinetics, and thermodynamic characteristics were also studied using batch assays. The optimum MB adsorption efficiency on LP and MLP occurred at a contact time of 180 min, pH of 6.0–9.0, and adsorbent dosage of 2 g/L. Langmuir, Freundlich and Dubinin–Radushkevich isotherms and a pseudo second-order kinetic model satisfactorily fit the equilibrium adsorption with high correlation coefficients (R2 > 0.97). Based on the Langmuir model, the maximum adsorption capacities of MB on LP and MLP were 100 and 139 mg/g, respectively. The results of thermodynamics studies indicated that MB adsorption on both LP and MLP was a spontaneous and exothermic process. The physical characteristics of LP and MLP were also studied using FTIR.

Using the dehydrogenase activity for alert of activated sludge system under different copper concentrations

Desalination and Water Treatment (2015)

Qian Feng Yubing Xiao Xiaochen Li Zhaoxia Xue Fang Fang

The aim of this study is to evaluate the effectiveness of dehydrogenase activities as an early warning indicator in wastewater treatment process under the impact of Cu(II). The substrate removals in sequencing batch reactors (SBR) on different Cu(II) concentrations (0, 5, 10, and 20 mg L−1) were investigated during long-term operation. Meanwhile, the dehydrogenase activities of activated sludge taken from SBR were observed in short-term bioassays. The results indicate that the inhibitory rates of Cu(II) on substrate removal efficiencies increased along with an increment of Cu(II) concentration. The dehydrogenase activities demonstrated similar trend. Logarithmic curves were used to describe the inhibitory effect of Cu(II) on dehydrogenase activities. Positive correlations were then obtained between the substrate removal efficiencies during long-term operation and dehydrogenase activities in short-term bioassays. Thus, 2-(p-iod-phenyl)-3-(p-nitrophenyl)-5-phenyltetrazolium chloride (INT)-dehydrogenase activity test can be applied as an effective method to alert the activated sludge system performance under the impact of heavy metal. In addition, median inhibitory concentration (IC50) by INT-dehydrogenase test after 1-h and 24-h Cu(II) exposure (5.93 mg L−1 for 1 h exposure and 5.45 mg L−1 for 24 h exposure) were obtained. These results showed that IC50 after 24 h of Cu(II) exposure appeared more sensitive to copper than that after 1 h. Therefore, INT-dehydrogenase test after 24 h Cu(II) exposure could be better fit for the early warning of wastewater treatment performance.

Timely and atomic-resolved high-temperature mechanical investigation of ductile fracture and atomistic mechanisms of tungsten

Nature Communications (2021)

Jianfei Zhang Yurong Li Xiaochen Li Yadi Zhai Qing Zhang

Abstract Revealing the atomistic mechanisms for the high-temperature mechanical behavior of materials is important for optimizing their properties for service at high-temperatures and their thermomechanical processing. However, due to materials microstructure’s dynamic recovery and the absence of available in situ techniques, the high-temperature deformation behavior and atomistic mechanisms of materials are difficult to evaluate. Here, we report the development of a microelectromechanical systems-based thermomechanical testing apparatus that enables mechanical testing at temperatures reaching 1556 K inside a transmission electron microscope for in situ investigation with atomic-resolution. With this unique technique, we first uncovered that tungsten fractures at 973 K in a ductile manner via a strain-induced multi-step body-centered cubic (BCC)-to-face-centered cubic (FCC) transformation and dislocation activities within the strain-induced FCC phase. Both events reduce the stress concentration at the crack tip and retard crack propagation. Our research provides an approach for timely and atomic-resolved high-temperature mechanical investigation of materials at high-temperatures.
