- 摘要:
- 三亚某水质净化厂扩建规模为4.0×104 m3/d,采用ABR-AO生化沉淀一体化工艺。该工艺的显著特点是分级曝气(O1~O5池)、二沉池V形构造、斜管沉淀池单斜壁结构,不仅能节省土建和占地,而且明显提高了生化系统的MLSS浓度、降低污泥负荷值,脱氮除磷效果突出,同时可节约缺氧脱氮碳源投加量。试运行37 d,一体化池出水COD、NH3-N、TN、TP平均值分别为12.0、0.31、10.54、0.37 mg/L,显著优于《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准,为后续反硝化深床滤池出水稳定达到地表水准Ⅳ类水质指标创造了有利条件,亦为低C/N比污水低成本脱氮除磷提供了参考。
- Abstract:
- The expansion scale of a water purification plant in Sanya is 4.0×104 m3/d, and the process is integrative ABR-AO biochemical sedimentation. The process is characterized by staged aeration (O1-O5 tanks), V-shaped structure of the secondary settling tank and single inclined wall structure of the inclined tube sedimentation tank. It can not only save civil construction and footprint area, but also significantly improve the MLSS of the biochemical system and reduce the sludge load. In addition, it has prominent nitrogen and phosphorus removal performance, and a lower amount of carbon source for anoxic nitrogen removal. After 37 days of trial operation, average COD, NH3-N, TN, TP in the effluent of integrative tank were 12.0, 0.31, 10.54, 0.37 mg/L, respectively, which was superior to the first level A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). The process creates an appropriate condition for effluent of the subsequent deep bed denitrification filter to steadily meet the quasi?Ⅳ surface water standard, and provides a reference for low?cost nitrogen and phosphorus removal of low C/N ratio wastewater.
