The ideal push flow process increases the driving force of biochemical reaction, improves efficiency and stable operation effect;
Resistant to shock load, there is treated water retained in the pool, which dilutes and buffers the sewage, and effectively resists the impact of water and organic pollutants;
The concentration gradient of DO and BOD5 in the reaction tank can effectively control the expansion of activated sludge;
Has a good denitrification and phosphorus removal effect;
The technological process is simple and the cost is low.
High requirements for automation control;
The drainage time is short, and the sedimentation sludge layer is required not to be stirred during drainage, so a special decanter is required, and the requirements for the decanter are very high;
The post-processing equipment requirements are large.
