<p>PURPOSE: A continuous biological water treatment system using an automatic water quality measuring machine is provided to reduce power cost by setting optimal retention time in an aeration tank, to actively deal with changes of an influent condition and a temperature condition, and to optimize driving condition. CONSTITUTION: A continuous biological water treatment system has a reaction tank (T) with an aeration tank (T3) and is divided by variable partition walls (Tp1,Tp2). The system comprises an automatic water quality measuring machine (Wa) for measuring TN concentration and a control unit. The control unit increases the space of the aeration tank by moving the variable partition wall when the measured TN concentration is greater than standard TN concentration, and reduces the space of the aeration tank when the TN concentration is less than the standard TN concentration.
