따라서, 오염방지시설의 설치가 법제화되고 오염물질 배출허용기준에 따른 규제가 점차 강화되는 실정이며, 오염물질 발생 사업장에서는 자체 관리인이 공인된 환경오염공정시험법에 의거하여 정기적으로 오염분석항목별로 수질을 측정 및 기록하고 있으며, 관할 환경감시기관에서도 이와 동일한 방법으로 수질을 관리 감시하고 있다.Therefore, the installation of pollution prevention facilities is legalized and the regulations according to the pollutant emission allowance standards are gradually strengthened.In the field of pollutant generation, the water quality of each pollution analysis item is regularly inspected by its manager in accordance with the certified environmental pollution process test method. The company monitors and monitors water quality in the same way.
그러나, 종래의 수질측정시스템은, 어느 한 시점의 오염도만을 측정하면서 오염도가 일정한도를 벗어났을 때에만 경보를 발생시키도록 시스템이 구축되었기 때문에 수질오염이 발생된 후에 조치되는 해결방안에만 의존하는 근본적인 문제점을 가지고 있다. 이로 인해, 체계적인 오염물질의 배출계획 및 관리가 어려워 효과적인 수질관리가 이루어질 수 없었다.
However, the conventional water quality measurement system is fundamentally based only on solutions that are taken after water pollution because the system is constructed to measure only the pollution at any point in time and to generate an alarm only when the pollution is out of a certain level. I have a problem. As a result, it was difficult to systematically plan and manage the emission of pollutants, so that effective water quality management could not be achieved.
본 발명은, 상기와 같은 문제점들을 해소하기 위해 이루어진 것으로서, 오염발생전에 사전에 알려주도록 시스템을 구축하여 체계적인 오염물질 배출계획 및 관리가 이루어지게 되는 수질측정시스템의 제공을 목적으로 한다.

제어부(30)는 데이터베이스에 실시간으로 저장되는 데이터들로부터 오염부하량을 산출한다. 오염부하량은 수질측정기(20)로부터 측정된 측정수의 오염농도와 유량측정기(10)로부터 측정된 총유량을 곱하는 식(1)에 의하여 산출된다.The
∑오염부하량(g)=오염농도(g/㎥)×유량(㎥)---------식(1)Pollution load (g) = pollution concentration (g / ㎥) x flow rate (㎥) --------- Formula (1)
본 실시예에서는 10분에 한번씩 자동으로 측정된 폐수의 오염농도와 총유량을 통해 오염부하량이 누적되도록 프로그램하였다.In this example, the pollutant load was accumulated through the pollutant concentration and the total flow rate of the wastewater measured automatically every 10 minutes.
상기의 과정을 통해 산출된 오염부하량은 관리자가 인지할 수 있는 수단을 통해 출력된다. 따라서, 관리자는 일정시점부터 배출된 오염부하 총량에 따른 오염물질의 과도유입이나 과도배출되는 것을 사전에 예측할 수 있으며, 유입/배출수량의 적절히 조절을 통해 예상되는 수질오염사고를 미연에 방지할 수 있다.The pollutant load calculated through the above process is output through means that the manager can recognize. Therefore, the manager can predict in advance the excessive inflow or excessive discharge of pollutant according to the total amount of pollutant discharged from a certain point of time, and prevent the expected water pollution accident by adjusting the inflow / emission volume in advance. have.
한편, 제어부(30)는 상기와 같은 과정을 통해 산출되는 오염부하량을 상시 체크하여 누적된 오염부하량이 기준량을 초과하였을 경우, 관리자에게 경고하여 적절한 조치를 취할 수 있도록 있게 하거나 폐수의 유입/배출용 펌프(미도시) 및 밸브(미도시)의 동작을 제어하기 위한 제어신호를 보내어 폐수의 유입/배출수량을 조절할 수도 있다.On the other hand, the
또한, 제어부(30)는 산출된 오염부하량에 비례하여 오염물질 배출요금이 산정되도록 하는 요금부과 프로그램을 더 구비할 수도 있다. 즉, 폐수가 유출되는 영업장에 유량측정기(10) 및 수질측정기(20)로부터 측정된 데이터들을 유/무선 통신기(50)를 통해 전송받은 제어부(30)가 오염부하량을 산출하고, 오염부하량에 비례하여 요금이 산정되는 요금부과 프로그램을 통해 각 영업장의 오염물질 배출요금이 부과되도록 하는 것이다. 이에 따라서, 수질관리가 보다 체계적이고 합리적으로 이루질 수 있다.
