摘要

摘要: 为改善厌氧反应器内的流态,加快污泥的颗粒化和形成具有生态梯度的微生物生态系统,设计并制作了新型厌氧多级喷动床,实验测试了反应器的水力喷动、气体喷涌和污泥分层分级现象。在常温下,利用新型厌氧多级喷动床接种混合污泥,经过42 d的培养,成功启动厌氧氨氧化反应器,稳定运行18 d后,NH₄⁺-N、NO₂^--N去除率均达到90%以上。启动60 d后,反应器底部出现大量粒径2 mm左右的颗粒污泥,且污泥具有良好的稳定性和沉降性能,沉降速度达到70 m/h。结果表明:厌氧多级喷动床因其特殊的水力结构,可有效加快污泥的颗粒化。

Abstract: In order to improve the flow state in the anaerobic reactor, accelerate the granulation of sludge and form an ecological gradient microbial ecosystem, a new type of anaerobic multi-stage spouted bed was designed and fabricated, and the hydraulic spout, gas jet and sludge stratification of the reactor were tested. At room temperature, the mixed sludge was inoculated into a new type of anaerobic multi-stage spouted bed. After 42 days of cultivation, the anaerobic ammonium oxidation reactor was successfully started. Through 18 days of stable operation, the removal rates of NH₄⁺-N and NO₂^--N were achieved of 90% above. After 60 days of starting, a large amount of granular sludge with particle size of about 2 mm appeared at the bottom of the reactor, which sludge had good stability and sedimentation performance, which sedimentation speed reached 70 m/h. The results showed that the anaerobic multi-stage spouted bed could effectively accelerate the granulation of sludge, due to its special hydraulic structure.
