In view of the high dissolved organic matter and salt content of the Mariculture wastewater in coastal industrial clusters, because that moving bed biofilm reactor (MBBR) normally faces the unbalanced carbon -nitrogen ratio and long flow, MBBR is rarely used for wastewater treatment of mariculture wastewater. Moving bed biofilm reactors of magnetic photocatalysis (MPBR) were treated with mariculture wastewater and constantly purified wastewater on a seawater ranch in Hebei. Results show that this biofilm colonization is completed faster than the other MBBR or magnetic photocatalysis microsphere. That typical constituents in this biofilm were confirmed by fourier transform infrared spectroscopy (FTIR). Pyrosequencing of 16srRNA revealed that SphaeroCalus was the predominating microbial community in MPBR. Therefore, the MPBR will be a promising alternative for the mariculture wastewater. These processing techniques can effectively reduce the risk of impact load on seawater ranch in Northern coastal areas.

Photocatalysis is an extraordinary and vastly researched topic; there is a need to find new ways to support producing composite materials that are cost-effective, efficient and have a low environmental impact. The investigation was undertaken on syn TiO2 by depositing it on silica. The results elucidate the positive effect on photocatalysis activity and the macroscopic structure on which the TiO2 is formed. For the analysis of photocatalyst, various characterisation measurements were undertaken, such as XRD, FTIR, DRS, FESEM, TEM, RS, and BET. The accumulated TiO2 onto the surface of SiO2 stabilised its transformation of the phase from anatase to rutile, resulting in decreased particle size and enhancing its photocatalytic activity under UV irradiation. The concentration of OH• radicals was determined using terephthalic acid as a probe molecule to determine its role in the photocatalytic degradation of antihistamine. The results of BET analysis showed that the syn TiO2-SiO2 sample has a large specific surface area of 192.6 m2 g−1. Maximum degradation of cetirizine (about 97%) was achieved with 80% TiO2-20% SiO2 (TS-4). Recyclability test confirmed that 80% TiO2-20% SiO2 sample was stable up to six cycles.
