- 摘要:
- 根据进水情况复杂、提标改造用地受限等问题，制定了污水厂提标改造技术决策路线图，其核心为生化处理单元，可优先采用“七段式”生化组合工艺。“七段式”生化组合工艺是在传统Bardenpho工艺上,增加预缺氧池和脱气池，改善脱氮除磷效果，同时在池型布置上进行改进，可实现传统A2O和两级AO之间灵活切换，实现多模式运行，能够灵活解决进水水质波动大、出水标准高、进水污染物浓度高等问题。工程案例表明，其脱氮率可达到74%，与传统A2O相比，节省碳源药剂费用0.06元/m3，节省除磷药剂费用0.02元/m3。
- Abstract:
- According to the complicated situation of water inflow and limited land for upgrading, the technical decision-making roadmap for upgrading of WWTPs is made. Its core is the biochemical treatment unit, which is “seven-segment” biochemical combined process in this work. Based on the traditional Bardenpho process, pre-anoxic tank and deoxygenation tank are added to improve the removal efficiency of nitrogen and phosphorus. Meanwhile, the layout of tank type is improved to realize the swtich between traditional A2O and two-stage AO to perform multi-mode operation. Thus, we could solve the problems such as remarkable fluctuation of influent quality, high standard of effluent quality and high concentration of influent pollutant. The engineering case shows that the denitrification rate can reach 74%. Compared with the traditional A2O, the cost of carbon source agent is saved by 0.06 yuan/m3, and the cost of phosphorus removal agent is saved by 0.02 yuan/m3.
