영문 초록

The treatment of the washout from small scale incinerator was performed physically, chemically and biologically. The results are as follows. 1. SS, FS removal efficiency of washout wastewater from incinerator was 67.4%, 37.4%, while SS, FS of sewage wastewater was removed 63.2% 35.4% respectively. 2. The optimal conditions for chemical coagulation turned out to be pH 7.5, alum(Al2O3 10%) 30ml/ι and polyelectrolyte(A-601P 0.1%) 4ml/ι. SS 86%, FS 89.5%, BOD 42.5% and CODMn, 63.5% was removed and the removal efficiency of some metals are shown as Pb 93.5%, Zn 86.5% and Fe 80.6%. The concentration of the effluent was SS 9mg/ι, BOD 98.4mg/ι, and CODMn 138.4mg/ι. 3. The removal efficiency in treating washout wastewater of incinerator through HBC-briquet media was getting higher with increasing HRT, and mixed wastewater with 1:1, 1:2 ratio could be met up to the standard limit with higher HRT than 12hr. Under the condition of 1:2 mix ratio and HRT 24 hr, removal efficiency of SS, BOD, CODMn, T-N and T-P was 92.1%, 90%, 87%, 48.2% and 48%, respectively, and the concentration of treated wastewater was SS 2.9 mg/ι, BOD 10.3mg/ι, CODMn 14.1mg/ι, T-N 11.6 mg/ι and T-P 1.3 mg/ι, respectively.
