METHOD FOR CLEANING WATER AND DEVICE THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a method for cleaning water by which the objective water under aerobic conditions can be efficiently cleaned by inducing both of nitrification reaction and denitrification reaction of the objective water under aerobic conditions by using a single embraced immobilization carrier, and to provide a device for the method. SOLUTION: In the device for cleaning water, the objective water under aerobic conditions is cleaned by introducing the water to a cleaning body housing the embraced immobilization carrier 1 in which microorganisms are immobilized by an immobilizing agent. The embraced immobilization carrier 1 is in such a size that the outer part 3 has aerobic conditions while the inner part 4 has anaerobic conditions.
