An Engineering Practice of Industrial Wastewater Treatment with Fe/Cu Bimetallic Process

Abstract:

Fe/Cu bimetallic process was developed as a new industrial wastewater pretreatment method. It was difficult for an industrial park wastewater treatment plant in Shanghai to treat the wastewater with many refractory pollutants and match the improved discharge standards. The plant needed renovation and adopted Fe/Cu process as a core pretreatment technology. 60,000 tons of wastewater is treated in the plant every day and the average removal rate of COD, BOD, total phosphorous (TP) and color was 73%, 77%, 55% and 48% respectively before renovation. After renovation, the average removal rate of COD, BOD, total phosphorous (TP) and color was reached to 86%, 93%, 76% and 85%, respectively. The engineering practice shows that the removal rate of COD, color and TP in Fe/Cu tank reached 29.7%, 60% and 53.6%. The continuous operating data in two years shows that Fe/Cu process can effectively improve the biodegradability of wastewater and enhanced the subsequent biological treatment. The successful engineering practice indicts that the slag dropping quickly effectively avoid agglomeration and clogging of the Fe/Cu filler and the operating cost is very low.
