摘要
无锡某新建污水处理厂设计规模为10×104 m3/d,采用两点进水及多模式运行方式的改良型A2/O工艺。生物池前端设置前置缺氧池,后端设置后缺氧池和后好氧池,进一步提高了脱氮除磷效果。实际运行监测结果表明,出水水质稳定达到GB 18918-2002一级A标准,其中TN平均质量浓度为8.4 mg/L,TP平均质量浓度为0.31 mg/L。
The design scale of new wastewater treatment plant in Wuxi city is 10×10^4 m^3/d, and the modified A^2/O process with two water and multi mode operation mode is adopted. There is a anoxic tank in the front of the biological; and the back is a anoxic tank and aaerobic tank, and the effect of nitrogen and phosphorus removal was further improved.The results show that the water quality of the effluent can reach the level of A GB 18918-2002 standard. The average value of total nitrogen was 8.4 mg/L, and the average total phosphorus was 0.31 mg/L.
