Treatment of UF-Concentrate of Dyeing Industrial Complex Wastewater by Chemical Oxidation Process = 綜合染色廢水의 限外膜濾過處理에 의해 生成된 濃縮水의 化學的 酸化處理

다국어 초록 (Multilingual Abstract)

ABSTRACTThe effluent CODMn of tested processes for the treatment of dyeing industrial
complex wastewater were followings : 183mg/ t by the oxygen activated sludge process,
75mg/1 by the oxygen activated sludge-coagulation process and 20mg/ t by the oxygen
activated sludge-coagulation-ultrafiltration process.The treatability of the concentrate from the oxygen activated
sludge-coagulation-ultrafil tration process was studied by the chemical oxidation
methods such as Fenton's reagent or ozonization.When the mixture of the dyeing wastewater and the oxidized concentrate was
treated at MLSS 4,500mg/<' and HRT 24hr by the oxygen activated sludge process, the
water quality of effluent was improved compared to the effluent of the dyeing
wastewater only treated by OAS process. From this result, it was found that the
mixture of the dyeing wastewater and the concentrate oxidized by chemical reagent
increased the biodegra-dability.
