本发明的工作原理：污水从厌氧段处的进水口流入，进行厌氧处理，污水中的有机物被厌氧细菌分解、代谢、消化，使得污水中的有机物含量大幅减少，然后污水通过潜水推流器自流至缺氧段，由于缺氧段设有曝气装置，进行间歇式微曝气，形成缺氧反应，反硝化去除硝态氮，同时去除部分BOD，且由于缺氧池内投加有MBBR填料，可吸附部分杂质、SS，然后污水通过缺氧池与好氧池之间分隔板上设置的溢流口/过水口流入好氧池进行好氧处理，进行生物代谢以降解有机物,使其稳定、无害化，且由于好氧池内不断曝气，内部投加的MBBR填料不断旋转滚动，形成MBBR流化床效果，然后污水通过好氧池与二沉池相连的管道流入二沉池，经二沉池内的倒梯形台结构和填充的斜管填料进行充分沉淀，过滤去除污水中的SS和杂质，一部分沉淀的污泥经污泥泵抽吸，通过管道将污泥排入污泥沉淀池中，进一步沉淀，一部分污水则通过二沉池与过滤池相邻的主隔板上的溢流口/过水口，流入过滤池，污泥沉淀池中一部分淤积的污泥经排泥管、污泥泵抽吸排出，防止淤堵，一部分则通过混合液回流装置经污泥泵抽吸回流至缺氧池中的厌氧段，形成硝化反硝化反应，进一步处理，过滤池的污水通过纤维滤布吸附过滤SS后，污水流入出水管，经出水管内的紫外线消毒装置消毒处理后排出或进入下一道工序。
