- Abstract:
- Xinjiang second wastewater treatment plant had a design capacity of 75 000 m3/d. The index of outflow was carried out by first class A standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918-2002）. Industrial wastewater accounts for about 70% of the influent. The influent quality fluctuates greatly and the risk of exceeding the standard is high. It has the characteristics of high concentration of refractory COD, TP and TN. In the engineering design, the treatment processes include accident regulating tank+hydrolysis acidification tank+improved A2O+MBBR+magnetic coagulation high-efficiency sedimentation tank+denitrification deep bed filter. On the basis of determining the main process scheme, multiple operation modes were established for different water quality conditions, and the design parameters were optimized through the software BioWin. Actual operation data showed that the operation of the wastewater treatment plant was stable, and the effluent quality was superior to the designed effluent standard.
