“…In order to comply with more stringent environmental regulations, numerous WWTPs have undergone upgrades and renovations, predominantly incorporating tertiary treatment processes. Physical and chemical methods have emerged as the most prevalent approaches in this regard [21,22]. However, the detection and analysis methods for emerging contaminants such as Pharmaceuticals and Personal Care Products (PPCPs), Endocrine Disruptors (EDs), Antibiotics Resistance Genes (ARGs), Persistent Organic Pollutants (POPs), MPs, etc., have only been mentioned in recent years, and our knowledge of the removal efficiency and mechanism of WWTPs for these contaminants is limited [23,24].…”

Microplastics have been widely detected in wastewater treatment plants, but there is still a significant dearth of research data on the removal efficiency of microplastics in such plants. The present study focused on three wastewater treatment plants situated in Zhengzhou, China. On-site sampling and Raman spectrum detection techniques were employed to identify microplastics in both wastewater and sludge samples, while the removal efficiency of microplastics was quantified for each plant. Results showed that the abundance of microplastics in influent exhibited ranging from 147.5 ± 2.6 to 288.8 ± 11.8 n/L, while the range in sludge samples was from 12,024.7 ± 1737.0 n/kgdw to 20,818.4 ± 5662.0 n/kgdw. The removal efficiencies of microplastics in the three WWTPs ranged from 76.2% to 91.2%. The primary components of microplastics were generally identified as fibers ranging in size from 10 to 100 μm. The samples collectively exhibited a total of seven distinct colors, with the predominant proportion being transparent. Polypropylene was the polymer type with the highest proportion. The sludge in WWTPs plays a pivotal role in the accumulation of MPs from wastewater bodies, necessitating increased attention toward its proper disposal in future endeavors.

“…Photocatalytic technology has become increasingly important as a green and sustainable technology [ 2 , 3 , 4 ]. Emerging contaminants, such as microplastics, persistent organic pollutants, antibiotics, pesticides, and endocrine disruptor chemicals, could damage the reproduction of human beings and animals [ 5 , 6 , 7 ]. Most of the emerging contaminants exist as organic pollutants and could be removed by the adsorptive and photocatalytic approach, which has recently gained broad attention [ 8 , 9 , 10 ].…”

Emerging contaminants, which mainly exist as organic pollutants and pose adverse biological effects, could be removed using photocatalytic degradation, resulting in a low-cost and environmentally friendly solution. Herein, BiVO4 nanoparticles with different morphologies and photocatalytic performances were synthesized by hydrothermal treatment at different residence times. The XRD and SEM results indicate that the crystal phase of BiVO4 gradually transformed from a single tetragonal phase to a single monoclinic crystal phase as the hydrothermal time increased, and with the extension of the hydrothermal time, the morphology of BiVO4 nanoparticles gradually differentiated from a smooth spherical shape to flower-like shapes composed of polyhedrons; the size of the crystals also increased accordingly. Methylene blue (MB), used as a probe of organic pollutants, was degraded under visible light irradiation by all BiVO4 samples to investigate its photocatalytic activities. The experimental results show that the longer the hydrothermal time, the better the photocatalytic performance. The optimum hydrothermal time was 24 h, at which the sample showed the highest photocatalytic activity for MB degradation. This work shows a convenient strategy for control of the crystal phase of BiVO4-based photocatalysts based on the understanding of the crystal morphology evolution mechanism, which will benefit the researchers in designing new BiVO4-based photocatalysts with high efficiency for emerging contaminants’ degradation.
