Document Type and Number:
WIPO Patent Application WO/2017/116158
Kind Code:
The present invention relates to an advanced water treatment apparatus which has a high treatment efficiency of nutrients and allows for excellent space utilization due to being small in size. The advanced water treatment apparatus according to the present invention comprises: a reservoir anaerobic tank (200) having a sewage water inlet (201) formed at one side thereof and performing solid-liquid separation of the sewage water; a biological reaction tank (300) for decomposing the sewage water introduced after being filtered by a filtration screen (310) with microorganisms by aerating and stirring the same; a membrane separation tank (400) for finally discharging the treated water, which has undergone the solid-liquid separation, by using a membrane; and a concentrated storage tank (500) for concentrating conveyed sludge. According to the present invention, the effluent treatment efficiency is excellent by effectively removing not only organic matter and pathogenic microorganisms but also nitrogen and phosphorus which are responsible for eutrophication and red tide. Since a separate storage tank is not necessary, downsizing is possible, an advanced water treatment apparatus to be installed in a small space has excellent space utilization and functionality.
