석가공폐수 처리는 처리 과정에서 약품응집제를 사용하고 있기 때문에 환경오염 및 생태계의 변화에 많은 문제점을 유발하고 있다. 본 연구에서는 경사분리기를 개발 제작하여, 석가공폐수처리에 대한 처리특성을 규명하고자 COD, SS, 탁도를 분석하였으며, 실험결과는 유입수량 0.3 ㎖/sec의 경우 회전속도 3500rpm에서 COD제거효율 86.92%~90.54%, SS제거효율 97.56%~98.53%이었고, 유입수량 0.4㎖/sec의 경우 회전속도 3500rpm에서 COD제거율효율 83.11%~89.46%, SS제거효율 96.33%~97.07%를 나타내었다. 탁도는 유출수에서 220~350NTU, 제거효율 98.24%~99.11%로 나타냈다. The present treatment system of stone wastewater cause various environmental pollutions in ecosystem due to the fact that it uses chemical coagulants in the treatment process. In this paper, we developed and manufactured the decanter and then analysed the removal retes of COD, SS and turbidity to reveal the treatment characters according to stone wastewater treatment. As a result experiment showed COD removal rete was 86.92%~ 90.54% and SS 97.56%~98.53% when the feed velocity was 0.3㎖/sec and rotational speed Was 3500rpm. On the other hand, It showed COD removal rate is 83.11%~89.46% and SS 96.33%~97.07% when the feed velocity was 0.4㎖/sec and rotational speed 3500rpm. Turbidity showed 220~350NTU, removal rate was 98.24%~99.11% in effluent water.

본 연구는 원심경사분리기의 처리특성을 규명하기 위해 수행된 것으로 온천오수를 대상으로 하여 그 처리 특성을 실험하였다. 원심경사분리기에 의한 온천오수의 처리 결과는, 유입량 0.084~0.390 ㎖/sec, 회전수 2000~4000rpm의 범위에서 COD 제거율 86.7~96.9%, BOD 제거율 88.3~99.4%, SS 제거율 89.7~99.7%을 나타냈으며, pH는 7.0~7.2이었다. 원심경사분리기의 최적 운전조건은 유입량 0.134㎖/sec, 회전수 4000rpm일 때 COD, BOD 및 SS의 제거율은 각각 96.8%, 99.5% 및 99.8%로 나타났다. 원심경사분리기의 회전수는 제거효율과 양의 상관이 있으나, 회전수 4000rpm 이상에서는 분리효율에 미치는 영향이 거의 없었다. This study was performed to examine the treatment characteristics of centrifuge with incline plate. The treatment characteristics were analyzed for the hot spring sewage. The results of the experiment for the treatment characteristics of the centrifuge with incline plate summarized as follows: The variation of COD removal rate was ranged 86.7% ~ 96.9%, that of BOD was 88.3% ~ 99.4%, that of SS was 89.7% ~99.7% and that of pH was 7.0 ~ 7.2, where the inflow varies in 0.084 ~ 0.390 ㎖/sec and the rotational speed varies in 2000 ~ 4000rpm. And the removal rate of COD, BOD and SS were 96.8%, 99.5% and 99.8%, respectively, where the inflow is 0.134㎖/sec and rotational speed is 4000rpm. The removal efficiency was positively correlated with the rotational speed less than 4000rpm. But the higher rotational speed showed poor correlation with the removal efficiency.

The sewage discharged by major hospitals contains quite different waste material from that of household sewage since hospital sewage is produced of clinical examination as well as patient care. This study intends to suggest a equipment capacity of the sewage and wastewater treatment through the multiple liner regression analysis and the inducement of the persumption model with the latest statistical date of service water, Patient number and bed number in the A. B and C major hospital. The main purose of this paper that reduce waterpollution by the sewage and wastewater discharging from hospital, decrease a burden load by shortage of the treatment capacity, losses economic losses by a excess equipment investment, calculate a capacity of the treatment about sewage and wastewater occurrence in hospital.

Spin machines, used to remove a component from a multiphase mixture, may be among the earliest used in human evolution. When environmental engineers realized the possible use of the centrifuge in the field of sludge treatment, centrifuges had already reached an advanced stage of development. Solids migrated through the liquid radially to the bowl wall by centrifugal forces. The bowl could rotate with an elevated speed up to 1000rpm. The removal of the very fine particles form the liquid requires comparatively high acceleration numbers of the centrifuge when flocculants are not used. The recovery, based on the solids content in the liquid may be between 80 and 97%.

Abstract On this study, I would like to study economic and rational design of the water distribution pipe networks by Lagrange Multiplier method. As daily life of human being and industrial development have close relations with water resources and the costs of water distribution facilities to utilize water resources amount to more than half of all construction costs, economic and rational optimum design to minimize construction costs of water distribution facilities is needed. So, this study will be much used in practical and rational design of the water distribution pipe networks, as it uses Lagrange Multiplier method optimizes to ideal diameter on design of the water distribution pipe networks, and then make optimum ideal diameter into standard diameter by standard program, and purchases practical diameter in actual spot and can be applied directly.
