Abstract:
1. A waste water treatment method, comprising the steps of: introducing waste water as treatment-receiving-water into a first micro-nano bubble generation tank for adding micro-nano bubbles, which are micrometer and nanometer size bubbles, to the treatment-receiving-water; introducing the treatment-receiving-water containing the micro-nano bubbles into a first microbe tank for applying first-stage microbial treatment to the treatment-receiving-water; introducing the treatment-receiving-water, after application of the first-stage microbial treatment, into a second micro-nano bubble generation tank for adding the micro-nano bubbles to the treatment-receiving-water; and then introducing the treatment-receiving-water containing micro-nano bubbles into a second microbe tank for applying second-stage microbial treatment to the treatment-receiving-waste, wherein the waste water is waste water containing organofluoric compounds or organochlorine compounds.
