Water treatment method, water treatment system, carbonized combustion material, and method for producing carbonized combustion material

Abstract

Provided is a technique capable of efficiently removing nitrogen contained in water to be treated and efficiently recovering microplastics from the water to be treated. An aspect of the present invention is a water treatment system 10 including an aquaculture tank 20 and a water treatment tank 30. Aquatic organisms are cultivated in the aquaculture tank 20. In the water treatment tank 30, algae having a microplastic adsorption and recovery ability grow in the water to be treated introduced from the aquaculture tank 20. The microplastics contained in the water to be treated are recovered, and the nitrogen compounds contained in the water to be treated are removed, by the algae.
