摘要:

跟着各地污水处置厂排放尺度的日益严酷，工艺流程短、出水结果好的AAO+MBR组合工艺得以快速普和，特别对用地面积重要、景不雅情况要求高的地下式污水处置厂，其更受青睐。但是AAO+MBR组合工艺并不是是保守AAO和新型膜手艺的简单叠加，其预处置、AAO、MBR等单位的设想与保守AAO均具有较着区分。连系国内浩繁项目案例，具体阐发了AAO+MBR组合工艺的设想要点，如预处置工段需按照进水水质选择设置初沉池，同时应设置膜格栅以免纤维、毛发等形成膜丝环绕纠缠；AAO工段的非凡性在在三级回流比简直定、AAO各区设想污泥浓度的计较、AAO+MBR各区现实流量的计较、需氧量的计较和强化脱氮办法的设想等；MBR工段的非凡性在在膜通量计较、膜区设想污泥浓度简直定、产水泵流量和扬程的计较、膜区底部吹扫设想和膜清洗设想等。

Abstract:

With the increasingly stringent discharge standards of sewage treatment plants in China, the AAO and MBR combined process with short process flow and good effluent quality has been rapidly popularized, especially for underground sewage treatment plants with limited footprint area and high landscape environment requirements. However, the combined process is not a simple superposition of traditional AAO and new membrane technology, and the design of pretreatment, AAO, MBR and other units are obviously different from that of traditional AAO. Based on many domestic en����Ϸappgineering cases, this paper analyzed the design points of AAO and MBR combined process in detail. For example, a primary sedimentation tank should be set according to the influent quality in the pretreatment section, and an ultrafine screen should be set to avoid the filament entanglement caused by fiber and hair. The particularity of AAO section lay in the determination of the three-stage reflux ratio, the calculation of the designed sludge concentration in each AAO section, the calculation of the actual flow of each section of AAO/MBR, the calculation of oxygen demand and the design of enhanced denitrification measures. The particularity of MBR section lay in the calculation of membrane flux, the determination of designed sludge concentration in membrane area, the calculation of pump flow and head, the design of the membrane air souring structure at the bottom of membrane area and the design of membrane cleaning method.
