PURPOSE: A wastewater treating apparatus for a vessel is provided to improve the purifying efficiency of vessel excrements and wastewater based on first purifying treatment and second advanced ozone treatment. CONSTITUTION: A wastewater treating apparatus(100) for a vessel includes a first aerating bath(10), a second aerating bath(20), a precipitating bath(40), a sterilizing and discharging bath(50), an ozone generator(60), and an ozone pressurization-dissolution-floatation-separation bath(65). The first aerating bath includes a screen(12) and a first aerating air-diffuser(13). The screen physically filters wastewater. The first aerating air-diffuser oxidizes and decomposes wastewater based on microorganisms in active sludge. The second aerating bath includes a second aerating air-diffuser(21). The precipitating bath precipitates floating matters or the active sludge form the second aerating bath to be separated into first treated water and precipitated sludge. A pressurizing and circulating pump(61) is installed in the sterilizing and discharging bath. |
