Title:
APPARATUS FOR TREATING ORGANIC WASTE WATER CONTAINING MICROBIOLOGICALLY DEGRADABLE MATTERS AND TREATMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2007/102379
Kind Code:
A1
Abstract:
It is intended to provide a low cost method, whereby waste water is treated in a
manner fitting for organic matters contained therein by taking the advantage
of an electrochemical treatment method, and an apparatus therefor. First, untreated
waste water (1) is introduced into a biological treatment step (a biological
treatment device) (2) wherein highly biologically degradable matters are separated
and removed to give biologically treated water (3) containing a large amount
of hardly biologically degradable matters. Next, this biologically treated
water (3) is introduced into an electrolysis step (an electrolysis tank) (4)
wherein the hardly biologically degradable matters are degraded into highly
biologically degradable matters such as VFA, carbon dioxide, water, etc. and
the water is discharged as electrolyzed water (5). A portion of this electrolyzed
water (5) is returned into the biological treatment step (the biological treatment
device) (2) as returned electrolyzed water (6) and the highly biologically degradable
matters contained in the returned electrolyzed water (6) are biologically treated.
