<p>PURPOSE: A wastewater treatment system by multiple sequencing batch reactors is provided to induce efficient removal reaction of nitrogen and phosphorus by using two or more of reactors and alternately setting injection of air and influent into the reactors according to characteristics of the influent, and its operation method is provided. CONSTITUTION: In a wastewater treatment system by multiple sequencing batch reactors comprising an inflow part for storing and supplying sewage and wastewater, sequencing batch reactors, an agitator(7) for agitating sewage and wastewater in the reactors, an air supply unit(5) for supplying air into the reactors, an air supply controller(6) for controlling supply of air into the reactors at a determined time, and a discharge unit(9) for discharging purified water in the reactors to the outside so that sewage and wastewater are treated through inflow step, anoxic, anaerobic and aerobic reaction step, precipitation step and discharging step in the reactors, the wastewater treatment system by multiple sequencing batch reactors is characterized in that two or more of sequencing batch reactors(3,4) are arranged in a row so that air is alternately supplied to each of the sequencing batch reactor, influent is continuously supplied to the reactors from the inflow part, and an automatic channel change unit(2) is installed to alternately change channels to the respective reactors at a determined time so that the influent is supplied into the reactors in the state that air is not supplied into the reactors.</p> |
