Abstract
PURPOSE: To obtain dischargeable purified water with high efficiency, by adding an NO2 salt to waste water containing NH4 +, polythionic acid, S-N compounds, etc., oxidizing the waste water with sludge containing sulfur bacteria and nitrifying bacteria, and then reducing nitrogen compounds in the waste water to N2 gas.
CONSTITUTION: Waste water containing NH4 +, NO2 -, NO3 -, polythionic acid and S-N compounds is introduced into a disposal vessel 3.The waste water in the vessel 3 is kept at pH about 4 or less and a temperature of about 60°C or higher. NO2-N, having a concentration at least equal to an expected N concentration of the S-N compounds, is fed to the waste water, and the waste water is agitated to decompose the S-N compounds into N2 or N2O gas and SO4 2-. The treated waste water is let flow into a pH-adjusting vessel 4, where the waste water is neutralized at pH about 6W8. Thereafter, the waste water is oxidized by sulfur bacteria in an aerobic disposal vessel 11 containing a sulfur compound, e.g. SCN- or the like, as a nutritious source. the waste water is further introduced into an anaerobic denitrifying vessel 2 containing denitrifying bacteria, where the waste water is agitated and fluidized to reduce most of NO2 - to N2 gas.
