<p><P>PROBLEM TO BE SOLVED: To provide a method for treating dialysis waste water, in which the dialysis waste water after artificial dialysis is performed is treated so that the treated dialysis waste water can be discharged into a sewer. <P>SOLUTION: The method for treating dialysis waste water comprises the steps of: neutralizing, if necessary, the dialysis waste water after artificial dialysis is performed so that the pH of the dialysis waste water becomes around 6-8; and bringing the neutralized waste water into contact with bacteria in a biological treatment tank 10 to treat the neutralized waste water biologically. The above step of bringing the neutralized waste water into contact with bacteria is combined with a step of filtering the waste water by using a hollow fiber membrane which is used in the form of a bundle 21 of hollow fiber membranes and is immersed in the biological treatment tank 10. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
