The invention relates to a method for regulating a water treatment plant (2) having an inlet (3), an ozonation stage (4), a transfer stage (5), at least one biological filter (6) and an outlet (7), comprising the following process steps: measuring a first parameter set in the inlet (3) by means of a UV/Vis sensor (8), wherein, based on the first parameter set, a measurement is determined for a first concentration of micro-contaminants (c1) and/or a nitrite concentration (n1); controlling the ozonation stage (4) such that ozone is supplied at a preselected ratio to the measured first parameter set (c1, n1); measuring a second parameter set in the transfer stage (5) by means of a UV/Vis sensor (9), wherein, based on the second parameter set, a measurement is determined for a second concentration of micro-contaminants (c2); regulating the ozonation such that the quotient of (c1-c2)/c1, representing the difference between the first concentration of micro-contaminants (c1) and the second concentration of micro-contaminants (c2) divided by the first concentration of micro-contaminants (c1), adopts a value between a predetermined minimum value and a predetermined maximum value; measuring a third parameter set in the process (7) by means of a UV/Vis sensor (10), wherein, based on the third parameter set, a measurement for a third concentration of micro-contaminants (c3) is determined; if the measurement for the concentration of micro-contaminants (c3) in the process (7) exceeds a predetermined maximum value, increasing the ozone supply in step 1.2. |
