  • High content organic wastewaters from different industrial sources were classified as waste emulsions with high suspended solid concentration, biorefractory wastewaters with high organic loading, high suspended solid organic wastewater without oil, organic wastewater containing chromium, emulsions with low suspended solid content which were treated by using acidification demulsification/Fenton oxidation/coagulation/flocculation, Fenton oxidation/coagulation/flocculation, coagulation/flocculation, reduction/coagulation/flocculation, vibrating membrane respectively. Performance of pretreatment was investigated in both laboratory experiments and full scale application. Results indicated that water quality of industrial wastewaters could be improved significantly by using pretreatment technologies, and effluent was fit for further biological treatment. The biological process has operated normally for 120 days, more than 90% of COD could be removed. The final effluent could meet the Water Quality Standards for Discharge to Municipal Sewers(CJ343-2012) after treatment by Fenton reagent at low dosage.

Abstract: High content organic wastewaters from different industrial sources were classified as waste emulsions with high suspended solid concentration, biorefractory wastewaters with high organic loading, high suspended solid organic wastewater without oil, organic wastewater containing chromium, emulsions with low suspended solid content which were treated by using acidification demulsification/Fenton oxidation/coagulation/flocculation, Fenton oxidation/coagulation/flocculation, coagulation/flocculation, reduction/coagulation/flocculation, vibrating membrane respectively. Performance of pretreatment was investigated in both laboratory experiments and full scale application. Results indicated that water quality of industrial wastewaters could be improved significantly by using pretreatment technologies, and effluent was fit for further biological treatment. The biological process has operated normally for 120 days, more than 90% of COD could be removed.
