- Abstract:
- The AAO process was adopted in Yancheng Chengdong wastewater treatment plant in original design plan, and the effluent water quality was required to meet the first level B standard in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002). In order to meet the first level A standard, the upgrading and renovation project was conducted. In this project, three AAO bioreaction tanks were transformed into MBBR tanks to achieve high efficiencies of nitrification and denitrification according to the simulation and analysis of biological treatment system. Meanwhile, TP and SS were removed by magnetic coagulation clarifier. The smelly structures of the whole plant were covered with fiberglass, and the “soil method” was adopted for deodorization. The total investment of the project was about 70 million yuan and the operating cost increased by 0.22 yuan/m3. In conclusion, an excellent treatment performance has been achieved after operation, and the MBBR+ magnetic coagulation process combined with soil deodorization, would be a good technology for the upgrading and renovation project of wastewater treatment plant in China.
