Research progress in aquaculture wastewater treatment technologies
Journal Title: Journal of Fisheries Research - Year 2025, Vol 47, Issue 3
Abstract
BackgroundWith the rapid expansion of the aquaculture industry, the impact of the resulting aquaculture wastewater on the environment, human production and life has become increasingly significant. Wastewater contains nutrients, pathogens and other harmful substances, if wastewater discharge directly without proper treatment, it will not only contaminate water bodies and disrupt the ecological balance, but also pose potential threats to human health. Therefore, the effective treatment of aquaculture wastewater has become a focal issue of concern both within and outside the industry. ProgressCurrently, aquaculture wastewater treatment technologies mainly include physical treatment, chemical treatment, biological treatment, and their combined treatment technologies. Due to differences in their treatment mechanisms, these technologies exhibit varied removal efficiencies for various pollutants. This review first introduces the composition of pollutants in aquaculture wastewater and their impacts on ecosystems, then describes a detailed analysis of the treatment mechanisms, advantages, and problems of each type of treatment technology. OutlookIn the future, wastewater treatment will further evolve towards intelligence, greenness, and integration. Further research is needed on how to achieve maximum pollutant removal through combined treatment methods while balancing economic benefits and environmental protection factors. SignificanceConducting in-depth research and development on aquaculture wastewater treatment technologies are of great significance for reducing environmental pollution during aquaculture processes, maintaining aquatic ecological balance, and also provides technical support and theoretical references for promoting the sustainable development of the aquaculture industry.
