Abstract
본 발명은 정수처리과정에서 응집처리를 하기 위한 응집제의 주입량을 결정하는 방법에 있어서, 과거의 원수 수질(pH, 알칼리도, 수온, 탁도, 전기전도도) 데이터 및 응집제 주입량 데이터로부터 응집제 주입량을 조절변수로, 원수 수질(pH, 알칼리도, 수온, 탁도, 전기전도도)을 제어변수로 하여 ARIMA모형을 이용한 시계열 분석을 통해 회귀식을 유추하는 단계; 상기 회귀식을 컴퓨터 연산자화하는 단계; 원수의 수질(pH, 알칼리도, 수온, 탁도, 전기전도도)을 측정하는 단계; 원수의 수질(pH, 알칼리도, 수온, 탁도, 전기전도도)을 컴퓨터 연산하여 응집제 주입량을 결정하는 단계; 응집제 주입 정량펌프의 속도를 조절하는 단계를 포함하는 것을 특징으로 하는 염소제 주입량 결정방법을 제공한다.
본 발명은 실시간으로 응집제의 주입량을 결정할 수 있고 적정량의 응집제를 주입할 수 있도록 하여 응집제의 소비량을 줄일 수 있을 뿐만 아니라, 종래의 수작업으로 행하던 일을 자동 시스템으로 대체하여 편리하고 저비용으로 시스템을 운영할 수 있는 효과가 있다.

Claims (2)
- 정수처리과정에서 응집처리를 하기 위한 응집제의 주입량을 결정하는 방법에 있어서,과거의 원수 수질(pH, 알칼리도, 수온, 탁도, 전기전도도) 데이터 및 응집제 주입량 데이터로부터 응집제 주입량을 조절변수로, 원수 수질(pH, 알칼리도, 수온, 탁도, 전기전도도)을 제어변수로 하여 ARIMA모형을 이용한 시계열 분석을 통해 회귀식을 유추하는 단계;
상기 회귀식을 컴퓨터 연산자화하는 단계;
원수의 수질(pH, 알칼리도, 수온, 탁도, 전기전도도)을 측정하는 단계;
원수의 수질을 컴퓨터 연산하여 응집제 주입량을 결정하는 단계;
응집제 주입 정량펌프의 속도를 조절하는 단계를 포함하는 것을 특징으로 하는 응집제 주입량 결정방법. - 응집처리를 위하여 응집제를 저장하는 응집제 저장조, 상기 응집처리가 진행되는 혼화지를 구비하는 정수처리장치에 있어서,
과거의 원수 수질(pH, 알칼리도, 수온, 탁도, 전기전도도) 데이터 및 응집제 주입량 데이터로부터 응집제 주입량을 조절변수로, 원수 수질(pH, 알칼리도, 수온, 탁도, 전기전도도)을 제어변수로 하여 ARIMA모형을 이용한 시계열 분석을 통해 회귀식을 유추하고, 유추한 회귀식을 컴퓨터 연산자화한 컴퓨터에 현재 측정된 원수 수질(pH, 알칼리도, 수온, 탁도, 전기전도도) 값을 도입하여 연산한 후, 연산된 응집제 주입량을 결정하여 필요한 양의 응집제를 공급할 수 있도록 정량펌프를 제어하는 응집제 주입량 제어부를 포함하는 것을 특징으로 하는 정수처리장치.
