Currently, the Strategy for the development of the fi shery sector of the Russian Federation for the period up to 2030 has been approved. To implement this strategy, the construction of new and reconstruction of existing enterprises is planned. Wastewater from fi sh processing contains a large amount of scales, remnants of entrails (liver, intestines, ovaries), proteins and lipids. Therefore, when developing a treatment technology, it is necessary to pay increased att ention to mechanical and physicochemical pre-treatment of effl uents. This article summarizes the experience of foreign and domestic research on mechanical and physical-chemical wastewater treatment. Also presented are the results of studies on wastewater treatment of two fi sh processing enterprises. The use of Al2(SO4)3 at a dose of 50 mg/l for Al2O3 gave the best results in a laboratory experiment.
