Application of Microelectrolysis-Fenton-Hydrolysis-Acidification-MBBR Process in the Treatment of Bromine Flame Retardant Wastewater
Bromine flame retardant wastewater has the characteristics of high toxicity,high CODCr,low B/C,and poor biodegradability.The micro electrolysis-Fenton-hydrolysis acidification-MBBR process was used to treat this wastewater.The results showed that after treatment with the combined process,the CODCr of the wastewater decreased from 7 500 mg/L to 800 mg/L,with CODCr removal rate of 90%.The removal effect was significant,and the system could operate continuously and stably for a long time.The successful application of this project indicated that the process has certain promotion value in the treatment of bromine flame retardant wastewater.
