METHOD FOR TREATING RECYCLE WATER OF WASTEWATER TREATMENT

摘要

The present invention provides a method for treating recycle water generated in a wastewater treatment process, which is configured to collect recycle water generated in a wastewater treating process, to remove phosphorous using reduction slag in a fluidized bed reactor (FBR), to perform advanced oxidation processes on non-biodegradable organic material included in the phosphorous-free recycle water in advanced oxidation processes (AOP), and to return the recycle water, obtained by biologically/physically treating the advanced oxidation-treated recycle water in a membrane bioreator (MBR), to a bioreactor tank or a grit chamber, thereby enabling the recycle water to be retreated. The method for treating recycle water according to the present invention does not generate impact load in a water treating process.
