Analysis of Organic Pollutants from Biologically Treated Coking Wastewater in a Multiple Barrier Method

Abstract:

The objective of this study was aimed to investigate the COD removal from biologically treated coking wastewater with a multiple barrier process of coagulation-flocculation (CF)/Fenton oxidation (FO)/ powdered activated carbon (PAC) adsorption. Optimized parameters validated by a series of processes were found to be FeCl3 concentration of 320.0 mg/L, anionic polyacrylamide (APAM) of 0.8 mg/L, the mass ratio mH2O2/mFe2+ of 4.7 and 500.0 mg/L of PAC, respectively. The total COD removal of 88.1% was obtained. Furthermore, through GC/MS analyzing of treated coking wastewater by stages, which was consistent with the COD removal. The results showed that the effluent treated by the integrated processes could meet the national second-grade standard of sewage comprehensive discharge in China and the requirements of reverse osmosis (RO) feed water. This implied the multiple barrier method had promising in practical applications.
