A photovoltaic powered ocean-based electrochemical system produces highly oxidizing active substances for simultaneous removal of antibiotics and heavy metals from mariculture wastewater
Mariculture wastewater contains a diverse array of pollutants, such as antibiotics, heavy metals, and ammonia nitrogen (-N). The concurrent removal of multiple pollutants has emerged as an urgent problem that demands immediate attention. In this research, photovoltaic powered ocean-based electrochemical system (POECs) was employed to treat mariculture wastewater. POECs exhibited outstanding performance in the treatment of mariculture wastewater, attaining high removal rates for various pollutants: 98 % for TC, 97.4 % for Cu(II), and 95.5 % for -N. The integration of the bioelectrochemical system (BES) and the electrolytic cell (EC) augmented the overall treatment capacity of the system. This integration led to the generation of a variety of highly oxidizing active species, including hydroxyl radicals and reactive chlorine species (RCS). In the anode chamber, the ocean - sourced sludge served as a source of bioelectricity. At the class level, functional microorganisms like Gammaproteobacteria and Campylobacteria were the dominant species. The study offers technical optimization for the environmentally-friendly treatment of mariculture wastewater and holds promising prospects for engineering applications.
期刊介绍:
Water Research, along with its open access companion journal Water Research X, serves as a platform for publishing original research papers covering various aspects of the science and technology related to the anthropogenic water cycle, water quality, and its management worldwide. The audience targeted by the journal comprises biologists, chemical engineers, chemists, civil engineers, environmental engineers, limnologists, and microbiologists. The scope of the journal include:
•Treatment processes for water and wastewaters (municipal, agricultural, industrial, and on-site treatment), including resource recovery and residuals management;
•Urban hydrology including sewer systems, stormwater management, and green infrastructure;
•Drinking water treatment and distribution;
•Potable and non-potable water reuse;
•Sanitation, public health, and risk assessment;
•Anaerobic digestion, solid and hazardous waste management, including source characterization and the effects and control of leachates and gaseous emissions;
•Contaminants (chemical, microbial, anthropogenic particles such as nanoparticles or microplastics) and related water quality sensing, monitoring, fate, and assessment;
•Anthropogenic impacts on inland, tidal, coastal and urban waters, focusing on surface and ground waters, and point and non-point sources of pollution;
•Environmental restoration, linked to surface water, groundwater and groundwater remediation;
•Analysis of the interfaces between sediments and water, and between water and atmosphere, focusing specifically on anthropogenic impacts;
•Mathematical modelling, systems analysis, machine learning, and beneficial use of big data related to the anthropogenic water cycle;
•Socio-economic, policy, and regulations studies.
