Abstract: 호소와 하천의 오염 및 부영양화의 주요 원인이 되고 있는 유기성 오·폐수에 함유된 유기물 및 영양염류를 효과적으로 처리할 수 있고 유출수를 중수도 수질로 정화시킬 수 있으며 기존의 처리방법에 비해서 작은 시설규모로 운용이 가능한 오폐수의 정화방법이 개시되어 있다. 본 발명에 따른 오폐수의 정화방법에서는, 시간변화에 따라 유량 및 농도변화가 매우 심한 분뇨 또는 오·폐수 처리시 희석수를 가하지 않고 간헐폭기 방식에 의해서 유기물 뿐만 아니라 영양염류(질소, 인)까지 제거하여 환경오염 방지에 기여한다. 즉, 유입되는 오·폐수 전량을 저류조에 저장하는 것이 아니라, 일정 유량 보다 유량이 많은 경우에 일정 유량 이상되는 것만을 저류조에 저류시킨 후 저류된 폐수를 유량이 적은 시간에 유입시킨다. 따라서, 저류조의 용량을 축소시킬 수 있고, 일정 표면적이 요구되는 침전조를 반응조내 설치하여 부지 요구량을 줄일 수 있다. 또한, 유기물, 질소 및 인의 제거가 주로 행해지는 2개의 간헐폭기 반응조에서 비폭기시 탈질산화 반응에 필요한 유기물(=전자공여체)을 혐기성 발효조에서 생성된 발효 유기산을 이용하여 효과적으로 탈질 및 탈인반응을 진행시킬 수 있다.

Title: 자동소화설비 모니터링 시스템
Filed: 1999-05-25
Abstract: 본 발명은 CO 2 또는 하론등의 자동소화설비 모니터링 시스템에 관한 것으로서, CO 2 또는 하론 등의 패키지 소화설비의 근처에 구비되어 불꽃 발생여부 및 온도 상태를 감지하는 소화설비 센서부와, 상기 소화설비 센서부로부터 검출신호를 인가받아 이상신호 검출시 이를 판단하여 에러 여부를 식별하는 서브 드라이브 콘트롤러부와, 상기 소화설비 센서부에서 감지된 검출데이터를 서브 드라이브 콘트롤러부까지 전송하기 위한 데이터 케이블부와, 선로상에 발생되는 노이즈로 인한 데이타의 손실을 막기위해 전송되는 데이터값을 보정하는 증폭기부와, 상기 서브 드라이브 콘트롤러부로부터 전송된 센서 검출데이터를 주기적으로 검색하여 저장한 후 센서 검출데이터를 기설정 정보와 비교 판단하고 전송받은 모든 감시정보를 화면상으로 출력하는 마스터 콘트롤러부와, 상기 마스터 콘트롤러부로부터 각종 감시정보를 전송받아 감시 및 에러경고 화면 디스플레이, 비상 알람 울림, 에러 메시지 인쇄 및 감시정보의 저장 처리과정을 제어하는 호스트 컴퓨터부와, 모니터부와, 상기 호스트 컴퓨터의 제어를 받아 이상사태 발생을 알리는 경보수단과, 프린터부로 구성함으로써 관리인력, 관리시간 등에 따르는 경비 절감을 할 수 있어 생산성을 향상시킬 수 있다.
