Summary: To tackle the challenges posed by high water consumption, massive wastewater discharge, and pollution risks in textile industries, different countries have adopted different treatment methods based on the location and management of textile enterprises. The complex characteristics of textile wastewater, such as high COD levels and toxic or non-biodegradable substances, present new problems for wastewater treatment plants. Coagulants play a key role in the pretreatment of textile wastewater, helping remove hydrophobic dyes and reduce SS and COD levels.

Summary: This study investigates the control of NO in marine ship exhaust and proposes a new method for NO2 removal based on hydrodynamic cavitation. The results show that hydrodynamic cavitation can delay but not prevent the production of NO, and the accumulation and decomposition of HNO2 are the primary causes of NO formation. Further experiments reveal that ClO2, H2O2, and Na2S2O8 can slightly increase the NO2 removal efficiency, while NaClO2 is less effective than water.

Summary: This study investigates the enhancement of antibiotic degradation in water through material-enhanced peroxymonosulfate (PMS) activation. By partially substituting the B-sites of perovskite oxides, oxygen vacancies are introduced and catalytic activity is enhanced. Experimental results show that the adsorption capacity of perovskite oxides to PMS and the presence of oxygen vacancies have a synergistic effect on the degradation reaction.

Summary: A sulfur-modified Fe3O4 composite (SF10) with excellent magnetic properties was prepared and showed superior performance in the activation of peroxydisulfate for atrazine degradation. The main active species were hydroxyl radical and sulfate radical. Sulfur modification introduced pyrite and pyrrhotite phases into Fe3O4 structure, enhancing its catalytic activity and electron transfer capacity. The study provides insights into the synergism between sulfur and iron and expands the application of Fe3O4 in PDS-based advanced oxidation processes.

Summary: This study assessed heavy metal contamination in the surface sediments of the Bharalu river in India. The concentrations of Ni, Zn, Pb, and Fe were analyzed and their levels were found to exceed the sediment quality guidelines. The pollution indices and risk assessment methods used in this study revealed a higher contamination in the downstream sites compared to the upstream site. Anthropogenic sources, such as urban discharges and waste dumping, were identified as the main contributors to metal contamination in the river sediments. These findings emphasize the need for effective river management strategies to address heavy metal pollution and protect the river ecosystem.

Summary: This study explores the use of N-doped graphdiyne nanotubes (NGNTs) as a catalyst for metal-free PMS activation in water remediation. The NGNT-PMS system decomposes heterocyclic contaminants via electron-transfer-mediated nonradical oxidation, where metastable NGNT-PMS* complexes act as the primary oxidants. The NGNT-PMS system exhibits higher reaction rates compared to N-doped carbon nanotubes (NCNTs) and graphene oxide (NGO) systems, and also plays a crucial role in the cleavage of pyridine heterocycles and C-Cl bonds.
