A sewage was treated using serially combined vertical and horizontal flow zeolite-filled reed bed. The sewage from thestudent dormitory of Changwon National University was fed into the reed bed for 10 minutes every 6 hours at thehydraulic load of 314 L/㎡․day. The reed bed depth was 100㎝ and the zeolite mixture was filled in the reed bed. Themixture consisted of the same volume of two types of zeolite ; 0.5∼1㎜ and 1∼3㎜ in diameter. pH value decreased invertical bed, while it increased in horizontal bed. But DO concentration in the effluent of both beds was higher than that inthe influent. Average removal efficiencies of the entire treatment system were 99.22% SS, 95.56% BOD, 91.02% CODCr,87.78% CODMn, 45.87% T-N, 99.88% NH4+-N and 71.17% T-P. Most of T-N in the effluent was NO3--N. However, theconcentration of NO2--N in the effluent was lower than 0.04 mg/L. All removal efficiencies did not show a remarkableseasonal change

본 연구의 목적은 직렬연결 수직 및 수평 흐름 갈대 제올라이트 인공습지에 생활하수를 간헐적으로 주입하였을 때 처리효율을 조사하는 것이다. 각 항목별 유입수에 대한 평균 처리효율은 수직 흐름 인공습지 유출수에서 BOD 92.42%, CODCr79.02%, CODMn 80.62%, SS 98.33%, T-N 37.06%, NH4+-N 99.45%, T-P 57.96%이었으며 수평 흐름 인공습지 유출수에서BOD 95.56%, CODCr 91.02%, CODMn 87.78%, SS 99.22%, T-N 45.87%, NH4+-N 99.88%, T-P 71.17%이었다. 최종 유출수 중T-N은 대부분이 NO3--N이었으며 NO2--N은 평균 0.04mg/L 이하이었다. 특히, 갈대 제올라이트 인공습지는 SS와 NH4+-N의처리에 탁월하였다
