(1) High solid-liquid separation efficiency, no need for a secondary sedimentation tank, reducing excess sludge production;
(2) Long sludge age, high concentration of activated sludge, fast degradation rate of organic matter, and high efficiency;
(3) The growth and reproduction of Nitrifying bacteria improve the nitrification capacity and efficiency of the system;
(4) Changing the operating mode can achieve the functions of removing organic matter, ammonia nitrogen, and total phosphorus respectively, resulting in good effluent quality;
(5) Strong resistance to impact loads, high concentration of activated sludge, helps to alleviate impact loads within a certain range;
(6) High volumetric load, low sludge load, long sludge age, almost achieving zero discharge of excess sludge;
(7 ) Single set processing scale: 50~200m3 /d;
(8) The effluent meets the requirements of the national discharge standard Class A discharge standard
