Abstract ：
Biological foaming is a major problem in activated sludge (AS) wastewater treatment systems. In this study, four wastewater treatment plants (WWTPs) (a total of six AS treatment systems) were investigated. The microscopic examination shows that foaming was mainly caused by gram-positive short branch microorganisms, sludge fragments, and/or other microorganisms, while the long unbranched filamentous was easy to cause bulking. The high throughput sequencing (HTS) and Linear discriminant analysis effect Size (LEfSe) identified the significant discrepancy of bacteria in foams compared to normal AS. Mycobacterium, Mycobacteriaceae, Nocardiaceae, Actinomycetales, Chryseobacterium, Flavobacterium, Ormithobacterium, Flavobacteriaceae, and Portibacter were considered as the dominant foaming-potential bacteria but not the most abundant bacteria in the foams. The excessive growth of foaming bacteria (including Haliscomentbacter, Saprospiraceae, and Tetrasphra) directly led to bulking with a high sludge volume index and was positively correlated with sludge retention time (SRT) and negatively correlated with dissolved oxygen (DO), which means long SRT and low DO may lead bulking instead of foaming. It also found that the foaming bacteria (including Skermania, Comamonadaceae, Cloacibacterium, Flavobacterium, and Chryseobacterium) had significant positive correlations with suspended solids and mixed liquid suspended solids, and negative correlations with temperature and DO concentration.

Abstract ：
The growing complexity of dyeing and printing effluents has presented considerable challenges for their effective treatment and recycling. Recently, there has been a notable increase in the development of loose nanofiltration (NF) membranes, which are characterised by their exceptional environmental resilience, high throughput, and superior dye/salt selectivity. This work presents the development of a new loose NF membrane prepared from a modified polymer called poly(ether sulfone ether ketone ketone) (PESEKK). The membrane features a dense- loose-support structure and is prepared through a straightforward one-step, non-solvent induced phase separation (NIPS) technique, eliminating the need for heating or post-treatment. Precise regulation of membrane pore size down to 4.27 nm can be achieved through modulation of PESEKK and pore-former composition. The membranes could separate positively and negatively charged dyes in mixed dye solutions accurately and selectively. Additionally, the membrane demonstrated exceptional dye/salt selective separation with a high water flux of 230.7 L m- 2 h- 1 bar- 1 , Congo red rejection of 99.91 +/- 0.13 %, NaCl rejection of 2.71 +/- 0.23 %, and a separation factor (alpha) of 347.4, outperforming state-of-the-art membranes. Remarkably, PESEKK membrane maintained outstanding stability and separation performance for up to 200 h under extreme environments, including NaOH solution (up to 9 mol L-1), NaClO solution (up to 40,000 mg L-1 h), n-hexane, isopropanol, and methanol. This high-performing loose NF membrane, developed using innovative polymer materials, offers a promising solution for treating the challenging wastewater generated by printing and dyeing processes.

Abstract ：
With the rapid growth of the demand for lithium-ion battery (LIBs), a large number of waste LIBs will be produced. If not disposed of properly, it will bring serious environmental pollution problems. The cathode materials of spent LIBs contain a large number of rare valuable metals, and the recovery of these metals will produce both environmental and economic benefits. Compared with the traditional separation, purification and recovery technologies of metal components from cathode materials, the strategy of direct regeneration of cathode materials has attracted much attention due to its advantages of simple process, low energy consumption, short recycling cycle and high added value of products. Six direct regeneration technologies for cathode materials from spent LIBs such as coprecipitation method, sol-gel method, solid phase sintering method, hydrothermal method, ion thermal/molten salt method and electrochemical repair method were reviewed and their advantages and disadvantages were also summarized. Among them, coprecipitation method and sol-gel method had some limitations in industrial application because of their relatively complex steps, high equipment requirements and reagent cost. Solid phase sintering method, hydrothermal method, ion thermal/molten salt method and electrochemical repair method had great opportunities for development because of their convenience and economy. In addition, the prospect and development trend of direct recycling of cathode materials from spent LIBs were prospected in order to provide reference for the research in the field of spent LIBs recycling. © 2024 Chemical Industry Press Co., Ltd..

Abstract ：
Electrocatalytic reduction of nitrate (NO3- ) to ammonium (NH4+) is an environment friendly approach for treating nitrogen-containing wastewater. Consequently, electrocatalysts capable of effectively and selectively reducing NO3 - to NH4+ receives growing attention. However, Cu-based catalysts demonstrate limited efficiency and the drawback of generating toxic NO2 - though it is prevalent in the field of electrocatalytic reduction of NO3 (NO3RR). In this work, a CuNi alloy was synthesized on a Co foil through electrodeposition (marked as CuNi@Co) and its electrocatalytic performance for NO3RR was evaluated. XRD, EDS mapping and XPS characterization indicate CuNi exists with alloy state. Electrocatalytic experiments demonstrate that CuNi@Co exhibits an exceptional FENH3 of 99.12% at -0.64 V (vs. RHE). Importantly, no detrimental NO2 - generated during NO3RR process because the reduction rate from NO2 - to NH4+ is faster than that from NO3 - to NO2- . Mechanistic analysis suggests that Cu serves as a 'reservoir' to provide electrons to facilitate the reduction of NO3 - to NO2during NO3RR process and the synergistic effect of Ni and Cu promotes more active hydrogen (H*) to participate the reduction process of NO2 - to NH4+ not H2 generation, ultimately improving FENH3. This work elucidates the role of electrons and H* in electrocatalytic nitrate reduction to ammonium for CuNi alloy, providing new insights into the reduction process of NO3RR for Cu-based materials.

Abstract ：
The presence of polyethylene terephthalate (PET) microplastics (MPs) in waters has posed considerable threats to the environment and humans. In this work, a heterogeneous electro-Fenton-activated persulfate oxidation system with the FeS2-modified carbon felt as the cathode (abbreviated as EF-SR) was proposed for the efficient degradation of PET MPs. The results showed that i) the EF-SR system removed 91.3 +/- 0.9 % of 100 mg/L PET after 12 h at the expense of trace loss (< 0.07 %) of [Fe] and that ii) dissolved organics and nanoplastics were first formed and accumulated and then quickly consumed in the EF-SR system. In addition to the destruction of the surface morphology, considerable changes in the surface structure of PET were noted after EF-SR treatment. On top of the emergence of the O-H bond, the ratio of C-O/C=O to C-C increased from 0.25 to 0.35, proving the rupture of the backbone of PET and the formation of oxygen-containing groups on the PET surface. With the verified involvement and contributions of SO4 center dot- and (OH,)-O-center dot three possible paths were proposed to describe the degradation of PET towards complete mineralization through chain cleavage and oxidation in the EF-SR system.

Abstract ：
Spinel-type complex oxides are considered promising electrocatalysts, nevertheless, the mechanism of electrocatalytic reduction of O 2 to generate H 2 O 2 and to activate H 2 O 2 still needs to be further explored. In this work, the dependence of selectivity of electrocatalytic O 2 to generate H 2 O 2 and the efficiency of activating H 2 O 2 of defect sites in ZnFe 2 O 4 /CNT composites were investigated based on experimental data and characterization. Firstly, the ZnFe 2 O 4 /CNT composites were obtained by hydrothermal method combined with high-temperature calcination. Then phenol was used as a typical pollutant to evaluate its electrocatalytic performance. The results indicated that ZnFe 2 O 4 /CNT can degrade nearly 100% phenol of 20 mg/L and appears excellent TOC removal efficiency. Impedance experiments showed that the existence of CNT significantly promoted the electron transfer for ZnFe 2 O 4 /CNT. Raman spectroscopy and XPS analysis disclosed that the defect degree of CNT as well as oxygen vacancies of ZnFe 2 O 4 in the ZnFe 2 O 4 /CNT composites were higher than those of the individual CNT and ZnFe 2 O 4 , greatly facilitating the adsorption of O 2 . Consequently, more O 2 was reduced electrocatalytically to H 2 O 2 via the 2e process. Free radical quenching experiments and Fenton experiments showed that homogeneous and heterogeneous activation jointly promoted the conversion of H 2 O 2 to center dot OH. This work provides a strategy for the design of efficient electrocatalysts with spinel structures.

Abstract ：
The chromium (Cr) pollution of soil has recently gained a lot of attention for the demand of environmental protection. One of its main resources is from the landfill of the chromium containing sludge (CCS) that produces from reduction-precipitation treatment of the Cr(VI) wastewater. In this work we provide an improved alkaline oxidation calcination (AOC) treatment for CCS, which achieves high Cr recovery efficiency at relatively low calcination temperature and oxygen-rich conditions. The leaching risk of the final residue is much reduced compared to the conventional calcination. It reveals that by using air flow the oxidation efficiency is effectively improved to a value of near to similar to 90 % at 450 degrees C. The thermal analyses of the reaction suggest that Cr (III) in CCS transforms to chromite at the temperature range of 340-450 degrees C, which ensure the subsequent oxidation. On the other hand, it reveals that at higher temperature ( 500 degrees C) it will produce Ca-Fe oxides which are confirmed to be dissolved in the leachate of the toxicity test. The concentration of Cr (III) increases obviously, which could be associated with the release of Cr(III) that doped into Ca-Fe oxides as solid solution. The transformations of the CCS components during the AOC process are depicted in detail. The method proposed here enables high oxidation efficiency of CCS and meanwhile avoids the environmental risk of final residue.

Abstract ：
Electrocatalytic reduction of nitrate to ammonia is an effective method for the recycling of NO3--N in the field of nitrate polluted water treatment. In this work, Co-N-C was prepared in this work by pyrolysis of Co-based metal organic framework at 700 degrees C and it can achieve 100 % selectivity to ammonia under the optimum experiment conditions. Impressively, no harmful nitrite generated in the reduction process because the reduction rate constant of Co-N-C for NO2- -N is higher than that of NO3- -N. Experiment results show that the chemical adsorption rather than electrostatic adsorption dominated among Co-N-C and free NO3- , which is significant for the subsequent electronic reduction process. Mechanism analysis indicated the active hydrogen (H*) reduction mechanism is predominate for Co-N-C but the direct electron mechanism is predominate for Co-C during the reduction from NO3- to NO2- . While for Co-N-C and Co-C, the subsequent reduction of NO3 to NH4+ was conducted by the direct electron mechanism. The present work not only explores high performance for the selectively electrocatalytic reduction from nitrate to ammonia but also promote new inspiration for the preparation of other Co-based functional materials for reducing the production of nitrite.
