高有机负荷冲击对填料型MBR运行性能的影响
|
摘要
针对分散式农村生活污水有机负荷变化明显的特点,研究了填料型厌氧-缺氧-好氧膜生物反应器(A~2O-MBR)抗高有机负荷的能力,考察了高有机负荷冲击对污染物去除效果、悬浮和附着污泥性质以及膜污染的影响.结果表明,高负荷冲击期间污染物去除稳定,氨氮去除率在冲击第3d从99.1%下降到78.5%,出水氨氮浓度高于5mg/L,随后去除率恢复至97.6%;悬浮和附着微生物的三磷酸腺苷(ATP)含量增加;附着生物量显著增加;细胞外聚合物(EPS)增加;高有机负荷冲击期间膜污染更严重,膜面污染层EPS含量显著增加;太阳能微动力A~2O-MBR系统能减少10%的碳排放.
Regarding the changing nature of the organic load in decentralized rural wastewater, the ability of the anaerobic-anoxicaerobic membrane bioreactor(A~2 O-MBR) with suspended carriers to resist the high organic load shock was studied. The effects of high organic load shock on the pollutant removal, properties of suspended and attached sludge as well as membrane fouling were investigated. The results showed that the pollutant removal was stable during high load shock. The removal rate of ammonia nitrogen decreased from 99.1% to 78.5% on the third day after the shock, and the ammonia nitrogen concentration in the effluent was higher than 5 mg/L. Then the removal rate of ammonia nitrogen recovered back to 97.6%. The adenosine triphosphate(ATP) content of suspended and attached microorganisms, the attached biomass and the content of extracellular polymer(EPS) increased. The membrane fouling became more serious, and EPS content of the membrane-fouling layer was increased significantly during the shock period. The solar-powered A~2 O-MBR system can cut down 10% of carbon emissions.
