영문 초록

The objectives of this study is to examine efficiency of swinery wastewater treatment by trickling filters pilot plant. The results of this study are as follows: 1. The characteristics of sample. The BOD₅ was from 2,450 to 2,880mg/l, COD(KMnO₄ acid method) was from 910 to 1,064mg/l, and SS was from 920 to 990mg/l. The pH of influent was from 7.3 to 7.6, and the temperature of water was from 17.0°C to 22.5°C. 2. For experiment by recirculation, the BOD₅ removal efficiency is 65.2% at recirculation ratio (r)=0, and 70.7% at r=1. The removal efficiency of this study is higher than NRC formula of U.S.A.. The recirculation is not significant effect on removal efficiency. 3. For experiment by hydraulic load, the BOD₅ removal rate decreased from 73.1% at 3.1m³/m²⋅d to 65.3% at 9.2 mm³/m²⋅d. The design formula of this study which shows the removal rate of soluble BOD is Le/Li=10^−0.24 D/Q^0.23 (Q: hydraulic load, D: depth of filter). 4. For experiment by organic load, the BOD₅ removal rate is increased from 70.2% at 0.77kg/m³⋅d to 75.4% at 4.28kg/m³⋅d. We can obtain the straight line y=0.749 x (y: removed BOD, x :applied BOD) by the least squares method. 5. We can know that trickling filters is strong with the hydraulic load and the organic matter shock load. Here, we can judge that trickling filters is a good method for the treatment of swinery wastewater which containing high concentrated organic matter.
