Abstract
This paper describes how to determine the amount of oxygen required for the catalytic wet-oxidation treatment of wastewater which contains highly concentrated organic substances and/or ammonia. Here is an outline of the rescach results.
(1) A simplified formula was developed to calculate an amount of oxygen required for oxidative decomposition and thus to determine a total oxygen demand (TOD) for various nitrogen compounds, which has been complicated so far. Using the simplified formula, the required oxygen amont can be more accurately determined with the TOD of wastewater as well as the analysis of nitrogen compounds such as ammonia in wastewater.
(2) It was also clear that using the air amount obtained by the simplified formula, organic substances, ammonia and other pollutants in wastewater-night soil and gas liquid in particular-can be efficiently treated.
