摘要

  • 摘要: 在常温的条件下,用厌氧折流板反应器(ABR)化粪池、YDT填料化粪池和传统三格式化粪池处理生活污水,进行了对照实验研究。实验结果表明,在温度为14~29℃,HRT为36 h时, 反应器运行85 d后,对以上3个反应器进出水中CODtot、CODdis、氨氮、总氮、总磷进行测定,在水温24℃稳定阶段,ABR化粪池和YDT填料化粪池CODtot去除率比传统化粪池分别提高30.5%和9.2%;在水温16℃稳定阶段时,该值分别提高10.9%和9.0%。总氮和氨氮去除率在5%~30%之间,稳定运行后总磷去除率为5%左右。通过测定3个反应器最后一格中厌氧污泥的比产甲烷速率,结果表明,ABR化粪池的厌氧污泥产甲烷的活性最好。此研究对传统化粪池的改造提出经济而行之有效办法,新型化粪池强化了化粪池出水的生化性和对污染物的去除,进而为化粪池的取舍和改造提供技术的参考依据。
    Abstract: Three on-site septic tanks, namely ABR-septic tank(R1), YDT-carrier-septic tank(R2) and traditional septic tank(R3), were operated in parallel over a three-month period under the hydraulic retention times (HRT) of 36 hours at sewage temperature of 14~29℃. The achieved CODtot removal efficiencies in R1 and R2 increased by 30.5% and 9.2%, respectively,compared with R3 at the stage of 24℃, while the value reduced to 10.9% and 9% in the phase of 16℃.The achieved removal efficiencies of TN and NH4+-N arrived at 5%~30%, and the value of TP was negligible,with approximately 5%. R1 achieved a better specific methane production rate as compared to R2 and R3. The two modified septic tanks improve biochemical characters and attain better removal efficiency for domestic sewage. The results provide a technical support and a theoretical basis for the modification of septic tank.
