Abstract:
The combined process, physicochemical pretreatment-UASB-hydrolysis acidifying-contact oxidation-bio-logical activated carbon filter, has been used for treating chemical wastewater in a company.The operation results show that the pretreatment process can obviously reduce the concentrations of chemical oxygen demand (COD) and salinity in high-concentration wastewater.The water quality of the effluent treated by the whole process reaches the take-over requirements.
