活性 슬러지에 의한 有害 廢水 處理度에 관한 硏究 : Formaldehyde 廢水 Formaldehyde Wastewater = Hazardous Wastewater Treatability by Activated Sludge

다국어 초록 (Multilingual Abstract)

The purpose of this research was to examine the possibility of biodegradation of the hazardous wastewater -formaldehyde wastewater- and to determine the engineering design parameters by the activated sludge process.
The main results of this experimental study are as follows:
1) It was indicated that formaldehyde wastewater can be treated by Activated sludge, and to accmplish the COD removal efficiency 90%, the HRT was above 11 days, COD volume loaling was below 096㎏ COD/㎥·d, and F/M_(v) ratio would be expected to have below 0.45
2) Oxygen reguirment was above 0.81㎏ O₂/㎏ CODrm and Sludge production was about 0.1㎏ VSS/㎏ CODrm.
