METHOD FOR TREATING WATER IN A SEQUENCING BATCH REACTOR |
摘要 |
<p>A method for treating water laden with nitrogen in the form of ammonium within a sequencing batch reactor, said method including: a first step of feeding said water into said sequencing batch reactor; an aerated nitritation step); an anoxic denitritation step; and a step of extracting treated water from said reactor. The method further includes an in-line measurement of the nitrite concentration of said water in said reactor, a step of measuring the pH of said water contained in said reactor, a step of determining information that is representative of the nitrous-acid (HNO2) concentration of said water contained in said reactor on the basis of said in-line measurement of the nitrite concentration and said pH measurement, and a step of controlling the duration of said aerated nitritation process in accordance with said nitrous-acid concentration.</p> |
