Optimization-close precise aerating method for sewage treatment

The invention discloses an optimization-close precise aerating method for sewage treatment. According to change of concentrations of dissolved oxygen online, aeration of biopools can be more preciselycontrolled by adjusting the aerating amounts of the biopools by adjusting the opening of an electric valve and the pressure of an air general pipe and adjusting the upper and lower limit values in adissolved oxygen concentration change area and the upper and lower limit values of the air general pipe in an optimization-close manner. 本发明公开了种污水处理趋近循优精确曝气方法，根据在线溶解氧浓度的变化，通过调节电动阀开度和空气总管压力来调节各生物池的曝气量，并可循优调整溶解氧浓度变化区间上、下限值以及空气总管压力的上、下限值，实现生物池曝气更为精确的控制。
