| Abstract |
This study applies to the Upflow contact oxidation Process for river purification. The ability of the plant to treat polluted stream water was determined and a suitable operating conditions were deduced. This study also presents a plan for effective use and operation maintenance. The results from the treatment efficiency from the Upflow contact oxidation method showed that the removal of BOD and SS depends more on the existence of aeration rather than treatment time. The best removal was seen at 2 hours retention time, and the presence of aeration proved to be twice as effective compared to the absence of aeration. The application of the Demo Plant in the field indicated a decrease in the inflow and outflow concentrations of BOD from 8.2㎎/ℓ to 4.3㎎/ℓ. The average removal percentage was 38%. However, at the 1.9 hour point of the 2 hour retention time, a maximum removal rate of 50.7% was seen. Also, if the operation were continued for 200 days, the pore is reduced 3.14% and backwash will be needed two times per year. |
