- 摘要:
- 河南省三门峡市某县城污水处理厂现状规模为3×104 m3/d，采用CAST+絮凝沉淀+纤维转盘过滤工艺，出水水质执行一级A排放标准。提标改造工程将出水水质提高到地表水准Ⅳ类水质。针对该厂进水NH3-N、TN浓度较高的特点，改造工程注重对脱氮功能的强化，即将生化系统CAST工艺改造为Bardenpho(A2O+AO)工艺，同时深度处理系统增加反硝化滤池（DN池）和曝气生物滤池（CN池）。项目改造后运行稳定良好，出水水质全面优于准Ⅳ类水质标准。
- Abstract:
- The current treatment scale of a county wastewater treatment plant of Sanmenxia City in Henan Province was 3×104 m3/d. The combination process of CAST+flocculation sedimentation+fiber rotary table filtration process was applied, and the effluent quality was required as first class A discharge standard. The project was required to improve the effluent quality to quasi-Ⅳ level. In view of the high concentration of NH3-N and TN in the influent, the transformation focused on the enhancement of denitrification performance, i.e. the biochemical system CAST process was transformed into Bardenpho process(A2O+AO), while the advanced treatment system was added with denitrification filter (DN tank) and biological aerated filter (CN tank). After the reconstruction of the project, the production operation is stable and the effect is good. The effluent quality is better than the quasiⅣ water quality standard.
