| 摘 要： | 倒置A2/O工艺已广泛应用于新建城镇污水处理厂和老厂脱氮除磷工艺的改造,但在实际运行中常因进水碳源不足和工艺控制不合理,致使出水磷含量无法达到一级A标准.在白龙港污水厂进行中试,研究了混合液回流比、曝气量、进水分流对倒置A2/O工艺除磷效果的影响.试验结果表明,对碳源含量偏低的进水,在保证出水氮浓度达标的前提下适当降低混合液回流比和曝气量,并采用进水分流措施可有效提高除磷效果,出水水质可满足一级A标准的要求.

| Abstract: | The inverted A2/O process has been widely adopted in newly constructed wastewater treatment plants and the reconstruction of nitrogen and phosphorus removal processes.In practice,the effluent phosphorus does not always meet A level of the national discharge standard due to unreasonable operation control and low carbon source in the influent.Using influent from the Bailonggang WWTP,a pilot-scale study was carried out to investigate the impact of internal return ratio,aeration rate and influent flow distribut... |
