A method and a system for controlling a sewage disposal plant by using the concentration of chlorine ions contained in sewage of a sewer pipe, which control the sewage disposal plant by estimating the contamination level and the flow amount of sewage flown into the sewage disposal plant, and a chlorine ion-measuring instrument used in the method and the system are provided. In a treatment zone of a sewer pipe with a predetermined area including at least one sewage disposal plant(110), a system for controlling the sewage disposal plant by using the concentration of chlorine ions contained in sewage of the sewer pipe comprises: a plurality of chlorine ion measuring instruments(150) installed on the sewer pipe within a plurality of monitoring areas(M) to measure the concentration of chlorine ions in sewage and transmit concentration data of the measured chlorine ions to remote places through wire or wireless communication means; flow amount measuring instruments(160) installed on the lowermost stream of the sewer pipe within the respective monitoring areas to measure the flow amount of sewage and transmit data of the measured flow amount to remote places through wire or wireless communication means; a main server(140) which is connected to the plurality of chlorine ion measuring instruments and the flow amount measuring instruments through the wire or wireless communication means, stores the concentration data of chlorine ions to judge if the water quality is changed, stores the data of flow amount to judge if the flow amount is changed, and evaluates the water quality and the flow amount of sewage flown into a sewage disposal apparatus(120) to store, output and transmit the evaluation results to remote places; and a sewage disposal plant control server(130) connected to the main server through the wire or wireless communication means to control the operation of the sewage disposal apparatus. |
