However, the existing treatment system had the original design defects and the equipment was seriously aged, thus the effluent was unable to meet the level A criteria in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), while the high operating cost greatly increased the enterprise’s burden. Therefore, the WWTP adopted a phased upgrading and reconstruction, by adding physical and chemical pre-treatment, optimizing biochemical treatment section and adding terminal advanced treatment section. Finally, the combined treatment process of ozone oxidation tank, hydrolysis acidification tank, A/O ����APPtank, secondary sedimentation tank, Fenton oxidation tank, high-density clarifier, V-type filter was formed. The combined process of sludge conditioning, plate and frame pressure filtration and low temperature drying was adopted for physicochemical sludge treatment. After the completion of the transformation, the effluent quality met the standard requirements stably, and the comprehensive operation cost was reduced by 2.5 yuan/m3. In the face of the new standard of Jiangsu Province that may be implemented in the later period, the existing V-type filter could be transformed into a denitrification biofilter to achieve advanced nitrogen removal, and an activated carbon adsorption tank could be added at the end of the whole process as a safeguard measure to achieve the removal of COD and residual organic nitrogen.类似文献/References:[1]潘名宾,潘维龙,陈燕波,等.某年夜型分析化工园区污水处置厂分质提标项目设想[J].中国给水排水,2021,37(18):70.
