| 摘 要： | 采用有效容积为240 L的中试Carrousel氧化沟处理模拟生活污水,研究了溶解氧对氧化沟同步硝化反硝化脱氮和除磷效果的影响。结果表明：溶解氧的变化对系统中有机物的去除影响不显著;过高或过低的溶解氧均会降低系统总氮和总磷的去除率,溶解氧控制在1.0～1.5 mg/L,系统可获得较高的氨氮和总氮去除率,当溶解氧为1.5...

| Abstract: | A pilot-scale Carrousel oxidation ditch with effective volume of 240 L was used for simulating wastewater treatment.The influence of dissolved oxygen(DO) on simultaneous nitrification and denitrification(SND) and phosphorus removal in the Carrousel oxidation ditch was investigated.The result shows that the effect of DO on the removal of organic substance in the system is not significant.Too high or too low DO would reduce the total nitrogen and total phosphorus removal rate.By controlling DO at 1.0~1.5 mg/L... |
