<p><P>PROBLEM TO BE SOLVED: To provide a method for treating drainage including dialysis treatment drainage capable of treating with more downsized installations. <P>SOLUTION: The method for treating drainage including dialysis treatment drainage produced via dialysis treatment includes a first stage in which the pH of the drainage is measured as a water quality indication of the drainage and the drainage is treated through neutralizing treatment followed by membrane-separation treatment and activated sludge treatment when the pH is 6 or below, and a second stage, when the pH is over 6, in which an electric conductivity and a chlorine concentration are measured as water quality indications of the drainage, and when the electric conductivity is 10 mS or over and the chlorine concentration is 10 mg/L or below, the drainage undergoes neutralizing treatment followed by membrane-separation treatment and activated sludge treatment, and when the electric conductivity is below 10 mS or the chlorine concentration is over 10 mg/L, the drainage undergoes the neutralizing treatment. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
