A water quality purifying system using a bio roll is provided to prevent erasure of soil and sand through a connection part because the connection part does not become weak although flood of water from river increases by connecting end parts of adjacent bio rolls using a connecting member each other and strengthening a connected state. A water quality purifying system using a bio roll sets up one or more bio rolls(10) in which biological filter media are filled inside in sides of river and purifies river. The bio rolls are fixed to the sides of river using a first rope(20) and a first pile(30). End parts of the adjacent bio rolls are connected by the second rope(40). |
