PURPOSE: A method and an apparatus for monitoring and controlling remotely a waste water treatment system are provided to reduce the environmental pollution by performing efficiently a waste water treatment process. CONSTITUTION: An apparatus for monitoring and controlling remotely a waste water treatment system includes a sensor for identifying the internal state information of the waste water treatment system and an interface(40) for monitoring and controlling the waste water treatment system. The sensor includes a D0 sensor(33), an ORP sensor(34), a temperature sensor(35), and an MLSS sensor(36). The D0 sensor(33) is used for sensing the dissolved oxygen concentration. The ORP sensor(34) is used for measuring the oxygen acidity of the solution within a tank. The temperature sensor(35) is used for measuring the internal temperature of the tank. The MLSS sensor(36) is used for measuring the floating solid. The interface(40) includes an ADC module(41), a DAC module(42), a memory module(43), DI0 module(44), a CPU, a backup module(46), and a display(47). The ADC module(41) and the DAC module(42) are used for converting an analog signal to a digital signal or the digital signal to the analog signal. The memory module(43) is used for storing the sensor information. The DI0 module(44) is sued for monitoring an operating state of a main controller. The CPU is used for comparing the measured values. The backup module(46) is used for storing the data. The display(47) is used for displaying the present state.
