PROBLEM TO BE SOLVED: To provide a method for treating wastewater produced by treating raw laver, enabling the wastewater to be cleaned and reused (used cyclically), and also to be sterilized as necessary. SOLUTION: This method for treating wastewater produced by treating raw laver comprises the following steps: subjecting wastewater produced by treating raw laver to primary filtration to separate large and small solids from the wastewater; subjecting the resultant filtrate to secondary filtration to separate minute solids from the filtrate; and thereafter cyclically using the thus filtered water by using it for raw laver treatment, or discharging it after sterilized. |
