- Abstract:
- The combined process of denitrification deep bed filter, ozone contact oxidation tank and activated carbon adsorption filter is adopted for advanced treatment of domestic sewage and industrial wastewater in Zhucheng Yinhe wastewater treatment plant (WWTP) with a treatment capacity of 10.6×104 m3/d. The main effluent indicators have reached level Ⅳ criteria in Environmental Quality Standards for Surface Water (GB 3838-2002), where COD≤30 mg/L, NH3-N≤1.5 mg/L, TN≤10 mg/L, TP≤0.2 mg/L, SS≤5 mg/L respectively. The TN removal rate was up to 68% without the increase of effluent COD concentration due to the successful cultivation of biofilm during commissioning in denitrification deep bed filter. COD was removed by 10 mg/L by ozone contact oxidation tank and activated carbon adsorption filter. The advanced treatment process is suitable for upgrading wastewater treatment plants mixed industrial wastewater to meet surface water standards, which plays a very important role in improving the surrounding water environment, protecting water quality and ecological balance of local river basins.
