Summary: In this study, excellent H2S removal performance was achieved by wet scrubbing persulfate solution combined with UV irradiation. The H2S removal efficiency was enhanced with the increase of UV power and initial (NH4)2S2O8 concentration, but restrained with the increase of initial H2S concentration and gas flow. Free radicals of sulfate radicals and hydroxyl radicals played a leading role in H2S oxidation in the advanced oxidation process.

Summary: The study focused on using a halotolerant strain of the genus Janibacter to remove phenol from saline wastewaters, showing that bacterial cells immobilized on mica and zeolite had higher removal efficiency, better thermostability, wider operating range, and longer reuse potential. The process involved complete destruction of phenol through the meta pathway involving phenol hydroxylase and catechol 2,3-dioxygenase enzymes, with zeolite-immobilized cells showing consistent efficiency even after 4 months of storage at low temperatures.

Summary: Thallium (Tl) and antimony (Sb) are toxic elements in the natural environment. The emerging pollution of Tl and Sb in water has become a global concern. However, there are limited technologies available for simultaneous removal of Tl and Sb from wastewater. In this study, a novel system was successfully developed using a MnFe2O4-biochar composite (MFBC) as an adsorbent and persulfate (PS) as an activator, which showed promising results for the simultaneous removal of Tl and Sb from wastewater.

Summary: In recent years, researchers have paid attention to novel disinfection processes for municipal wastewater treatment plant effluents due to the global demand for reusable water. Conventional disinfection processes have raised concerns about effluent quality fluctuations and the spread of emerging contaminants into the environment. This study focuses on the degradation of amoxicillin using sulfate radical-based advanced oxidation processes (SR-AOPs) for disinfection purposes. The results show that UV activation of SR-AOPs is an efficient method for disinfection and removal of pharmaceutical contaminants.

Summary: Organic contaminant abatement by upgraded electrochemical process is highly efficient. An electrochemical advanced oxidation process is developed by combining in situ electro-generation of persulfate on beta-PbO2 anode and hydrogen peroxide on carbon cathode. The presence of reactive species, such as 1O2, ·OH, and SO4·-, produced on-site contributes to the strong oxidant power and mineralization. The application of oxygen-depolarized electrode not only produces hydrogen peroxide but also reduces cell voltage and energy consumption.

Summary: The presence of antibiotics in the aquatic environment can cause significant environmental and human health problems. Conventional treatment systems are ineffective in removing these antibiotics. This study utilized oxidation and adsorption techniques to explore the removal of chloramphenicol, a recalcitrant antibiotic. An aluminum-based metal-organic framework was prepared and used as an adsorbent and catalyst. The results showed that the framework had high surface area and porosity, and effectively removed chloramphenicol through adsorption and oxidation processes.

Summary: Methylisothiazolinone (MIT) is efficiently degraded by vacuum ultraviolet (VUV)/ultraviolet (UV) irradiation, with the presence of .center dot & nbsp;OH as the main oxidant. The degradation efficiency of MIT under VUV/UV irradiation is higher than under UV irradiation, and is influenced by solution pH and the concentration of CO32- /HCO3-. The study also identified the main degradation mechanisms of MIT as sulfur atom oxidation and hydroxyl addition, with VUV/UV degradation being an effective method to remove MIT toxicity.

Summary: This study evaluated the feasibility of N-methyldiethanolamine (MDEA) degradation through electrochemical activation of persulfate (PS). The results showed that the dosage of PS, voltage, and initial pH had an impact on the removal rate of MDEA, and the synergistic effect between SO4-. and the three-dimensional electrochemical system increased the removal rate. In addition, kinetic analysis revealed that the degradation process followed a pseudo-first-order model and the reaction rate increased with increasing voltage.

Summary: The direct use of Fe-III is more convenient than Fe-II in iron-based advanced oxidation processes (AOPs), but the reduction of Fe-III to Fe-II is a rate-limiting step. Introducing co-catalysts with abundant reducing sites, such as molybdenum disulfide (MoS2), can enhance the catalytic performance of Fe-based AOPs for phenol removal. The results showed that MoS2 effectively facilitated the reduction of Fe3+ to Fe2+ and maintained the Fe2+/Fe ratio, enabling the use of Fe3+ in AOPs.

Summary: This study evaluated the color wastewater treatment in the textile industry using the persulfate/dithionite (PS/DTN) process. By optimizing pH, PS, DTN, and reaction time, the efficiency of the PS/DTN process in removing COD from the textile wastewater was determined. Although the removal efficiency reached 64.9% for COD and 54.5% for TOC under optimal conditions, it did not meet the required discharge conditions and standards. However, the process showed a good ability to improve the biodegradability properties of the wastewater.

Summary: In this study, the removal of nitrate and total coliforms using zeolite-supported bimetallic nanoparticles coupled with ultrasonic treatment was investigated. The results showed that the nitrate removal efficiency increased with higher catalyst concentration and ultrasonic frequency, while the total coliform removal efficiency increased with higher total coliform concentration. Optimization results demonstrated a maximum removal efficiency of 97.77% for both nitrate and coliforms. Comparatively, ultrasonic treatment alone and ultrasonic treatment coupled with Z-nZVI/Cu catalyst were found to be the most effective methods for removing total coliforms and nitrate from aqueous solutions.

Summary: This study investigated the inhibition of bis(2-ethylhexyl) phthalate (DEHP) in flocculent and granular sludge sequencing batch reactors (GSBRs) used for treating landfill leachate. It was found that GSBRs exhibited high performance in SCOD and DEHP removal at concentrations of up to 200 μg/L, while the process ceased in FSBRs at 200 and 400 μg of DEHP/L. Different dosing concentrations of DEHP led to the gradual accumulation of inhibitory compounds and limited DEHP degradation at inhibitory concentrations.

Summary: The study used non-thermal plasma and aerobic granules to treat landfill leachate, with the plasma reactor showing high efficiency in removing heavy metals and quasi-metals. However, the removal efficiency of COD decreased with different concentrations and hydraulic retention times, indicating the potential of aerobic granules in reducing organic load and heavy metals. Further full-scale studies at landfill sites are recommended for heavy metal and organic loading reduction, presenting new research opportunities for different contaminants in leachate from various landfill areas.

Summary: In this paper, a novel needle-shaped Zinc organic framework (Zn-MOF/CE) was formed on the surface of a functionalized graphite electrode, providing a systematic alternative electrode. The ZnMOF modifier was characterized by XRD, FT-IR, FESEM-EDS mapping, and N2 sorption. The modified electrode exhibited high stability and conductivity, making it an ideal working electrode. The redox process of hydroquinone at the modified electrode surface was optimized and modeled using the central composite design method, showing the best performance at a scan rate of 560 mV/s and pH of 9.9. Frequency domain using bode plots and CCD results could be employed for stability and electrode material performance prediction.

Summary: This study investigated the efficiency of a hybrid system combining 3DE electrochemical treatment with MBBR biological treatment for removing 2,4-D herbicides. The results showed that increasing current density, decreasing pH, decreasing herbicide concentration and increasing electrolysis time improved the degradation efficiency in the 3DE pretreatment process. In the MBBR post-treatment process, increasing HRT and filling ratio also increased herbicide removal efficiency. The identified consortium of 2,4-D degrading bacteria in the MBBR process included various bacterial species, and the overall process showed relatively high efficiency in 2,4-D herbicide degradation.
