Study On Micro-electrolysis, Fenton Reagent And Immobilized Microorganism Technique Combination Processes In Dyeing Wastewater Treatment

The dyeing waste water was one of the high concentration organic and hard treatment industry waste water and discharged straightly without being treated, these wastewaters would pollute environment.Especially, at the same time the rapid development of township enterprises in recent years, the small dyeing factories were rapidly developed, too.The production process of these small factories were backward, and lots of these factories were lack of practical and effective treatment technologies, so the waste water of these factories was discharged straightly; in this situation, these factories had caused serious pollution to aquatic ecosystems and its borders had bring in some significant environmental impact. The poisoning incident was increasing.Dyeing industry varieties, which processes complex, particularly with water containing the dye with the characteristic of effect large distribution extensive, water quality change was big, high Cod, color depth, high salinity and debiodegradation, so the waste water had been treated difficultly. Dyeing wastewater treatment was difficult to deal with and the treatment cost were high, and the research of treatment of dyeing wastewater was a hot spot.According to principles wastewater treatment methods can be marking physics,chemistry,physical chemistry,biochemical and so on. For wastewater that has the characters of simpleness composition,biodegradation,lower concentration can adopt routine physics,chemistry,physical chemistry,biochemical and craftwork of unite treatment. But if the wastewater is...
