The present invention provides an upflow reactor system for sewage and wastewater treatment. The upflow reactor system comprises an upflow reactor (10), an aerobic reactor (20), and a settling tank (30). The upward reactor (10) includes: a trough (11) which sewage, wastewater, and returned sludge from the settling tank (30) flow inside; one or more distribution pipes (12) discharging the wastewater, the wastewater, and the returned sludge by being installed in the lower part of the trough (11); an outer trough (17) installed outside the trough (11), wherein the sewage and the wastewater flow into the outer trough (17); and one or more distribution pipes (18) discharging the sewage and wastewater by being installed in the lower part of the outer trough (17). A dual trough (11, 17) and the distribution pipe (12, 18) are separately installed. A reaction area is formed by being divided into two such as a lower reaction area (A) of an aerobic tank and an upper reaction area (B) of an anaerobic tank. The upflow reaction system is designed for the position of the distribution pipe (18) to be adjusted in accordance with the water quality of the wastewater and the sewage in a range in which a ratio Q_1:Q_2 of the amount (Q_1) flowing into the lower reaction area (A) of the aerobic tank and the amount flowing into the upper reaction area (B) of the anaerobic tank becomes 2:0.5-1. The upflow reaction system for sewage and wastewater treatment can achieve an anaerobic reaction in a single reactor by using the reactor of an extrusion flow form with excellent reaction efficiency. 본 발명은 상향류 반응조(10), 호기 반응조(20) 및 침전조(30)로 이루어지는 상향류 반응조 시스템에 있어서, 상기 상향류 반응조(10)가 하·폐수 및 침전조(30)로부터의 반송 슬러지가 유입되는 트러프(trough)(11), 상기 트러프(11) 하부에 설치되어 상기 하·폐수 및 반송 슬러지를 배출시키는 하나 이상의 분배관(12), 상기 트러프(11) 외부쪽에 설치되어 하·폐수가 유입되는 외부 트러프(17), 및 상기 외부 트러프(17) 하부에 설치되어 상기 하·폐수를 배출시키는 하나 이상의 분배관(18)을 포함하고, 이중의 트러프(11, 17)와 분배관(12, 18)을 별도로 설치함으로써 반응영역을 무산소조의 하부 반응영역(A)과 혐기조의 상부 반응영역(B) 2개로 분리하여 형성할 수 있는 하·폐수 처리를 위한 상향류 반응조 시스템을 개시한다. 무산소조의 하부 반응영역(A)으로 유입되는 양(Q)과 혐기조의 상부 반응영역(B)으로 유입되는 양(Q)의 비율 Q:Q가 2:0.5~1이 되는 범위 내에서, 상기 배출관(18)의 위치가 하·폐수의 수질에 따라 조정되도록 설계된다.
