Abstract

PURPOSE: To make sewage as high quality treated water by adding a catalyst to an effluent of a secondary treatment process from a sewage treatment facility, recovering the catalyst while treating the effluent with ozone, and filtering the resulting effluent after adding a flocculant.
CONSTITUTION: Flowing water to be treated is led to the secondary treatment process 8 such as an activated sludge process, and a suspension catalyst (e.g. iron oxide catalyst) 9 is added to the treated water flowing out from the secondary treatment process. Then, it is led to ozone treatment process 10 and while carring out the ozone treatment, the suspension catalyst 9 is recovered and recycled. Further, after a flocculant 11 is added to the ozone treated water flowing out from the ozone treatment process 10 and adding a trace of the suspension catalyst 9, treated water is obtained through a sand filtration process 12. Periodically cleaned water in the sand filtration process 12 is sent to a sludge treating process 13.
