PURPOSE : A water treatment apparatus of an eco-pond is provided to maintain water quality of the eco-pond in the base state by forcibly circulating rainwater in an eco-pond using power, filtering the rainwater at least twice, sterilizing or disinfecting the rainwater, and accurately purifying the rainwater, and properly realize the function of a pleasant and clean ecological part by maintaining a constant level of water in the eco-pond. CONSTITUTION : A water treatment apparatus of an eco-pond(EP) comprises : an eco-pond into which collected rainwater is supplied; a circulation pump(11) operated by a control part to circulate forcibly supernatant of the eco-pond through a line(13) for water to be treated; a first filter(15) installed on the line for water to be treated to remove relatively large adulterations, earth and sand, and suspended solids; a second filter(17) installed in rear of the first filter to remove fine turbid components, and adsorb and remove organic matters, residual chlorine, floating dust, nitrogen oxides, and sulfur oxides; an advanced oxidation equipment(19) for sterilizing/disinfecting the secondly filtered supernatant using ultraviolet rays and ozone, and supplying the sterilized/disinfected supernatant into the eco-pond again; a reservoir(1) for storing the rainwater after removing contaminants from initial rainwater, collecting the rainwater through a roof or housetop of a building and a separate catchment means, and removing relatively large adulterations from the rainwater through a contaminant treating equipment(3); underwater pumps(5) for forcibly transferring rainwater that has stayed in the reservoir for a predetermined time to replenish the rainwater into the eco-pond through a supplementary water line(7); and a water level sensor(9) for measuring a water level of the eco-pond to send out a signal to the control part when water is deficient, and operating the underwater pumps by the control part to supplement the rainwater into the eco-pond. © KIPO 2008
