METHOD FOR TREATING WATER WITHIN A SEQUENTIAL BIOLOGICAL REACTOR COMPRISING AN ONLINE MEASUREMENT OF THE CONCENTRATION OF NITRITES WITHIN THE REACTOR

摘要

The invention relates to a method for treating a water charged with nitrogen in ammonium form, said process comprising at least: a first step (i) of supplying said water of a sequential biological reactor (10); a step (ii) aerated nitritation; a step (iii) anoxia of denitration; a step (iv) of extracting a treated water from said reactor; According to the invention, such a method further comprises an on-line measurement of the nitrite concentration of said water present in said reactor, and at least one step of controlling at least one step of the process, said control step taking into account results of said on-line measurement of nitrite concentration.
