- 摘要:
- 新江水质净化二厂设计规模为7.5×104 m3/d，出水水质执行《城镇污水处理厂污染物排放标准》（GB 18918—2002）中的一级A标准。进水中工业废水量约占70%，进水水质波动大，超标风险高，具有难降解COD及TP、TN浓度高等水质特征。设计采用事故调节池＋水解酸化池+改良A2O+MBBR+磁混凝高效沉淀池+反硝化深床滤池处理工艺。在确定主体工艺方案的基础上，建立了多水质工况运行模式，并利用BioWin软件分析优化设计参数。实际运行结果表明，污水厂运行稳定，出水水质优于设计出水标准。
- 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.
