Abstract PURPOSE: A remote control method for a waste water processing equipment is provided to obtain information on environment, varied by real time, and to use the obtained information for a flow rate or a pollution variation. CONSTITUTION: The method comprises several steps. An optimal theoretical value for an optimal operating control is set according to a variation of a waste water quantity and quality item(S1). Real time data sensed by sensors, operating data output by each waste water processing equipment, and theoretical values are collected(S2). The collected data are processed, and it is checked whether a current state is optimal(S3). In a case that the current state is optimal, an operation of the waste water processing equipment is controlled by converting control data for each time according to a variation of a water quality item(S4), and it is checked whether there exists a non-continuous control condition in an operation control process(S5). In a case that there does not exist a non-continuous control condition, it is checked whether there exist different control conditions for each similar condition(S6). In a case that there do not exist different conditions, an optimal operating condition with respect to time is stored, and the waste water processing equipment is operated on a basis of the optimal operating condition(S7, S8). In a case that there exists a non-continuous control condition or there exist different control condition in the similar condition, an operating condition is set on a basis of a fuzzy or a statistical method(S9). 본 발명은 유입하폐수의 수량 및 수질농도에 따른 하폐수처리장의 최적운전을 위한 이론적 최적운전 값 설정 스텝과, 최적운전일 때와 일치하는 각 센서의 실시간 감지 데이터 및 각 기계장치의 작동 데이터를 수집하는 데이터 수집 스텝과, 이론적 최적운전 값과 실제 가동시 최적운전 값 사이에 차이를 판단하여 이론적 최적운전 값을 수정·보완할 뿐만 아니라 이와 일치하는 센서감지 데이터 및 장치작동 데이터를 수정·보완하는 최적운전 세팅 스텝과, 유입하폐수의 수량 및 수질농도 변화가 일어날 때마다 이에 맞추어 여러 가지의 기 세팅 값을 동시에 변환시키는 세팅 변환제어 스텝으로 이루어진 하수처리장 운전제어 장치이며, 이 장치를 원격으로 제어하는 방법에 관한 것이다. 현재 하폐수처리장의 자동운전을 위한 세팅 값은 시시각각으로 일어나는 유입하수의 수량 및 수질농도의 변화 시에 이와 일치하는 세팅 값의 즉각적인 변환이 어렵고, 실시간 감지 센서의 데이터에 따라 변환되도록 세팅된 자동운전 값도 감지 센서의 감도 저하나 오작동이 빈번히 일어나 하수처리장의 기능이 최대로 발휘되지 못하고 있는 실정이다. 따라서 본 발명품은 하수처리장 운전 시에 나타나는 이러한 문제점들을 해결하기 위한 것이다.
