Abstract: 우리 나라의 하수종말처리장에 유입되는 하수는 BOD(생화학적산소요구량) 값이 평균 86.5mg/L, T-N(총질소)의 값이 40∼70mg/L로서 유입수질이 설계수질에 크게 미치지 못하고 있으며 특히, BOD/T-N비의 값이 낮아 질소 및 인의 제거를 위한 고도처리공정을 도입하는 데에는 여러 가지 어려움이 많다. 하폐수의 질소 및 인을 제거하기 위한 고도처리공정에서는 폐수의 C/N비 및 C/P비가 중요하므로 유입 탄소원이 부족한 경우 외부탄소원으로서 메탄올을 권장하고 있으나 고가의 메탄올 구입비용은 고도처리 공정의 운영비에 엄청난 부담을 주게됨으로서 하폐수의 고도처리를 더욱 어렵게 하는 요인이 되고 있다. 혐기성 조건하에서 하수슬러지내의 입자성 유기물 성분은 용해성유기물로 가수분해되며, 용해성 유기물은 산발효균에 의해 유기산으로 전환된다. 하수슬러지의 산발효공정으로부터 생산된 유기산은 탈질공정에서 효율적인 외부탄소원으로 사용될 수 있다. 국내의 경우 1997년말 현재 하루에 약 12,391 천톤의 하수가 처리되고 있으며, 하수에서 분리된 하수슬러지의 발생량은 전체 처리하수량의 약 1-2%에 달하는 것으로 알려지고 있다. 그러나, 국내에서는 아직까지 하수슬러지로부터 고도처리용 외부탄소원을 개발하기 위한 연구가 수행된 예가 드물고 체계적이지 못하여, 대부분 고도처리공정에서는 외부탄소원으로서 값비싼 메탄올을 활용하는 경우가 많다. 이러한 현실은 단순히 유기자원으로서 활용가치가 대단히 우수한 하수슬러지를 그냥 낭비하는 것에 그치는 것이 아니라 하수슬러지의 처리 및 처분에 막대한 별도의 노력과 예산이 낭비되고 있다는 측면에서 대단히 심각한 상황이다. 따라서 본 발명은 하수처리 과정에서 발생되는 1차하수슬러지 및 2차하수슬러지 등의 폐슬러지를 이용하여 하폐수의 고도처리용 탄소원을 제조하여 하폐수의 고도처리를 위해 경제적으로 외부 탄소원을 공급하는 동시에 발생되는 폐슬러지의 양을 줄이는 데 그 목적을 두었다. 
     본 발명의 핵심기술은 하수슬러지의 고효율 산발효 기술 및 이를 이용한 적절한 질소제거 기술로서 크게 산발효 공정과 탈질 공정으로 구성되어 있다. 산발효 공정은 하수의 1차 슬러지와 2차 슬러지를 고효율 산발효 시키는 산발효조와 고액분리조, 산발효 후 잔류고형물의 추가적인 가수분해를 가능케하는 가수분해촉진조 등의 단위공정들으로 구성되고 탈질 기술 공정은 제 1 호기조(Primary aerobic zone), 준혐기조(Anoxic zone), 제 2 호기조(Secondary aerobic zone)와 침전조로 구성된다. 유입 하폐수는 제 1호기조(Primary aerobic zone)로 유입되며, 산발효조에서 생성된 탄소원은 준혐기조(Anoxic zone)로 유입되어 탈질이 이루어지도록 되어 있다. 
     본 발명에 따른 효과는 하수슬러지의 산발효기술과 이를 이용한 질소제거 기술에 대한 것으로서, 이 것은 국내에서 하수슬러지의 처리와 동시에 부가가치가 높은 유가물질의 생산기술에 대한 개발의 시효가 된다는 측면과 하수의 고도처리시에 부족한 외부탄소원 개발의 파급효과가 크다고 할 수 있다. 또한, 하수슬러지를 이용한 산발효 공정에 의해 유기산을 만들어 탈질공정의 유기탄소원으로 사용함으로써 하수슬러지의 처리와 함께 질소 제거율을 향상시킬 수 있어, 기존의 고도처리공정에 요구되는 메탄올과 같은 화학적 유기탄소원을 대체할 수 있다는 경제적인 장점이 있으며, 나아가 국가적인 경제산업발전에 크게 기여 가능하다.
